I’d really like to tell you about these Mustard Roasted New Potatoes, but I have a really really good excuse for keeping this post short.
See…
I’m practicing my booty dance moves around my apartment. I just ate two, frozen, unfrosted cupcakes and I plan on eating at least two more.
I have a scarf wrapped around my head and slippery socks on.
So you’ll have to forgive me.
I’m swamped.
This booty isn’t going to dance itself… nor will these frozen cupcakes eat themselves.
Also! Completely unrelated pro-tip: always always ALWAYS mute Eharmony commercials. They’re totally annoying.
It’s alright that I’m dancing around my apartment with a scarf on my head.
It’s totally cool… because the description of these potatoes is pretty dang straight forward.
There’s whole grain mustard, whipped with melted butter and olive oil and garlic and lemon. It’s tossed with thin-skinned new potatoes and baked until crisp and flavorful.
Um. Dreamtime!!
The potatoes are browned and mustardy on the outside, and light and creamy on the inside.
Bake them. Eat them. Practice that booty dance.
Ok… you guys are freaking out about this salad.
It’s my big sister’s creation. Romaine lettuce, carrots, cucumber, scallions, edamame, and avocado. She tossed it with some sort of miso sesame dressing, from a jar…. it was incredible.
Mustard Roasted New Potatoes
serves 4 or 6 as a side dish
adapted slightly from epicurious
3 pounds new potatoes
1/2 cup whole grain dijon mustard
3 tablespoons olive oil
2 tablespoons unsalted butter, melted
2 cloves garlic, minced
3 tablespoon fresh lemon juice
1 teaspoon lemon zest
1 teaspoon kosher salt
ground black pepper to taste
1/2 medium yellow onion, sliced
chopped fresh parsley to taste
Place a rack in the center of the oven and preheat to 425 degrees F. Line two baking sheets with foil or parchment paper, and spray with non-stick cooking spray. Set baking sheets aside.
Clean and dice new potatoes. Try to slice them so they’re just about all the same size. Place in a large bowl. Toss in sliced onions.
In a small bowl, whisk together mustard, olive oil, melted butter, minced garlic, lemon juice, zest, and salt. Pour mustard mixture over diced potatoes and onions. Toss until potatoes are coated. Divide the coated potatoes between the two baking sheets. Leave any extra mustard mixture in the bowl. It will just burn in the oven.
Bake potatoes for 20 minutes. Remove from the oven and toss. Return to the oven and bake for another 25 minutes, or until the potatoes are browned and cooked through. Remove from the oven, toss with parsley, and serve warm. They’re yummy.

I used homemade Dijon for this and I guess it was a mistake. My husband and I found the flavor to be underwhelming. I don’t mean to be rude, I just like leaving a review whenever I try a blogger’s recipe.
I should note that they didn’t go unenjoyed, the potatoes… They were delicious dipped in steak juices and a melted compound butter.
You shouldn’t support the use of glass cutting boards. Terrible for your knives.
I don’t have any garlic cloves..:( Can this be substituted for garlic powder or something similar??
These are amazing :) have made them 2x now and everyone who I’ve served them to loves them!
I’m not a huge potato fan, but these look totally awesome. Might have to make them at my next dinner party!
Made these tonight and they were awesome. Everyone raved about them. Definitely going to make these again!
Wow! These are amazing! I had no idea mustard on potatoes could taste so good! I made these tonight and they will definitely be in my regular rotation from now on.
these were outta control good…made tonight, served with fritatta & a caprese salad. yay! also, big ole congratulations on the Saveur award! so well deserved
I just made a mushroom-shallot quiche and was wondering what to serve with it for dinner. It’s going to be these potatoes, along with some salad. Thanks!
I made these potatoes over the weekend.
SO easy!
SO deelish!
My potatoes looked like your potatoes – *BONUS!* :-)
Thanks much.

Dear Joy,
I made this potato dish yesterday when my boyfriend was over for supper. It should be said that my boyfriend is a very picky eater who gets apprehensive about trying new foods. Well, he loved these potatoes. And so did I. Thank you for sharing this great recipe!
These are amaze!!! I halved the recipe and had to try reeeally hard to not eat all of them by myself in one sitting. So delicious!
Oh dear I want to eat these right now. This is definitely the next way I am preparing potatoes! Thanks!
we are baking these right now. the smell is amazing! need to find a recipe for making whole grain mustard pronto.
You should look up the definition for dice, because that’s not what you did to those potatoes.
entirely helpful. thanks.
!! These look amazing! <3 I must must must try these asap!
haha I found myself eating a frozen cupcake a few days ago (who am I kidding? Im also eating one right now) and I couldn't help but think of you! There's just an indescribable amazingness when they're frozen :)
They were delightful. I was surprised that each of the flavors came through after baking for 45 minutes, the lemon and little mustard grains especially. I tossed in some sweet potatoes cut the same size and they were excellent bowlmates. Thanks!
I made this as a side dish for my in-laws tonight and it was a big hit. I loved the flavor and it will definitely become a part of the regular rotation. Thank you!
Oh.my.goodness. These are AMAZING. Though, if you do not like your onions completely CHARRED (I do. I’m one of those people that turns bonfire ‘mallow toasting into balls of fire on the end of a stick. yum.) then I would recommend slicing your onions kind of on the thicker side. I ate this dish with ketchup but is it still phenomenal without it. (I have a strong love, borderline obsession, for ketchup)
Definitely a keeper!!! Thanks Joy!! (btw, I read your blog so much that I feel like I know you. If I ever visit LA, don’t be surprised if I show up at your doorstep to hang out. Now that I read that sentence out loud, that sounds super creepy. But I really just wanted to say that I think we would be BFFs if we lived in the same city. That’s less creepy, right?)
I made these. They were delicious. I think next time I will have to add a little more mustard though. =) great recipe.
This dish has everything I love: mustard, potatoes, garlic and onions! It looks like something that would be a great side dish to almost anything. The photo is great and makes them look all crusty and yummy.
I am pleased as punch to say that I made these Monday night and they were totes delish. Even my picky, I-don’t-like-mustard husband ate (and enjoyed) them! (I ate the rest for lunch yesterday and they were still goooood.)
Yay for booty dancing! My favorite kind of dancing!
Will you forigve if I make this tonight with ‘old” potatoes? I kinda sorta have to make these tonight. No, right now. Forget taking the wee ones to school – this is why the created the term ‘hooky’
I blame you. I had mustard roast vegetables on the brain. But I bought cocoa. After I made truffles and shortbread I ended up making chocolate-roasted aubergines. DISASTER.
Hi Joy,
I just wanted to let you know that you are awesome. I’m graduating from college this saturday and am feeling uncertain about which path to take. You inspire me to pursue my passion for food! Thanks for making me laugh whenever I read a new post (:
Besos,
Roxy
ps love the new text in the photos, adds even more of your personality to your posts
Wow, these look amazing. So amazing that i’m craving roasted potatoes at 11.30am!
I’m not a huge potato fan, but these look totally awesome. Might have to make them at my next dinner party!
Anyone tried Spicy brown mustard for this recipe?! That’s all I have in my pantry, but my taste buds are watering just looking at these pics!
I was thinking exactly the same thing!!! I’m too cheap and lazy to go out and buy a whole new bottle of mustard…but I really want this. What a predicament. Please let me know how it turns out if you end up using spicy brown mustard instead!
We don’t have brown mustard here in Ukraine, but I did use a spicy mustard. The extra kick was perfection. Give it a try and I hope it’s spectacular!
Definitely potatoes worth dancing for! Whole-grain dijon mustard is one of the great loves of my life!
YUM!!! These potatoes look incredible, and easy to do also! I will definitely be trying these out soon! My family will think I am the greatest for making this!
What’s in this mustard??!
Those potatoes look spectacular! Would it be too much to serve them with mustard chicken? I love how even the spiciest mustards get all mellow and complex when they get cooked. Yumm.
And that salad is a must have! Keep on dancing!
Maybe you should change the blog title to Joy in the Kitchen, rather than Joy the Baker since not all your articles are related to baking….
I love reading your blog – you have shared many recipes that are fun to try.
i’m pretty sure i’ll stick with Joy the Baker.
Looks FANtastic!
joy, that salad was AMAZING…seriously I read the post this afternoon, went to Trader Joe’s and made that salad for dinner tonight. We paired it with some wild salmon marinated in Tjoe’s Soyaki…OH MY!
thank you so much it was INCREDIBLE :)
Sounds like you had a blast dancing around in your fuzzy socks. Sweet cupcakes chased by salty potatoes, nice! xo
This one time I was listening to hip-hop and draining my mac(pre-cheese) and noticed my face looked funny in the side of the pot… so… naturally I made a thug face and danced a little… lost 68.4% of my noodles in the sink. 49.6% landed in a rinsed out frying pan. Cleaned that off under some water… good as new!
Moral of the story… always rinse your pots out prior to dancing in the kitchen.
Potatoes ROCK!! I’ve added mustard to creamy mashed potatoes before. Loves it!! Mustard is a must in potato salad!! Now I have a new variation on the mustard potato marraige. I wonder if potatoes and mustard first met on EHarmony??? Well, all the power to them. As for booty dancing with scarves on (AND with you sister, no less)…the last time I did that with my sisters we were in our training bras and panties and had tucked all the scarves from grandma’s drawer in the waistband of our Hanes so that we could pretend that we were starring in an ‘I Dream of Jeannie’ episode. GIRLS ROCK TOO!!
amazeballs.
get the dancing. that booty ain’t gonna shake itself :)
Mmmmm I love, love, love potatoes! They are the only vegetables I eat (and I don’t eat fruit either, hope I don’t get scurvy!) and these look fantastic! I wanna make them now!
This post just made my day. I giggled, “yummed” and now I want potatoes with mustard. Good job!
Yum. Yum. Yum. These look delicious. Thanks for the recipe.
I need these potatoes in my life. Stat.
Oh my gosh these potatoes sound amazing! I would be dancing around my house too
!
Oh my, those potatoes look dreamy and creamy and I need to try them!
Um, i <3 you, mustard-y, buttery, onion-y, potato loveliness. That salad looks scrumdiddlyumptious (yes, as a matter of fact, I did google the spelling) too.
I want to try this. I can imagine the yumminess
I can’t knock eharmony. I met my sweet husband that way 7 years ago.
These look excellent.
These potatoes look amazing! Will def be trying!
POTATOOOOOOES! excellent. I am always looking for a new way to eat my favorite food. :) thanks for your magical blog writing, Joy!
Ha! I just got some new potatoes in my weekly CSA stash, and came here on a whim to look for an inspiring recipe. That booty-dancing is impressive stuff, Joy, to get you so attuned to the needs of your readers: per. fect. recipe. Thanks!
I was sure the first photo was of peanuts. Then I read the title, figured it was potatoes, then kept thinking the photos were of peanuts. What does that say about me?
I’m am ready to dig in to those potatoes and that salad. Except I’m making sukiyaki tonight, so maybe I’d better wait until a little later. ;-)
My mother-in-law found the love of her life on Eharmony and they were married 3 months after they found each other! They are perfect for each other! :]
I should definitely try these. My normal potato routine is to cut them with my wavy cutter and then toss them with a tiny amount of salt, lots of black pepper, and a lot of chipotle and freshly ground cumin. (or just lemon pepper if I am in a rush)
Aah Joy, those mustard roasted potatoes were fabulous! What a Mother’s Day treat you surprised us with!
Hi joy. Love the mustard dressing for the new potatoes and the salad looks yum. Know what you mean about the eharmony commercials! We get these in the Uk as well and they are pretty shocking; I dont think turning the sound down is enough – maybe throwing something at the tv set as well…:)
You’re a genius.
Joy! I don’t even like potatoes (at all), and somehow these still look kinda yummy!
Looks so good! I love the really grainy mustards.
Yum! The potatoes must have a really good taste! Spicy and all. You should try a “pommes de terre à la lyonnaise”, it’s pretty tasty!
Ah, and keep dancing ^^
These look incredible! Love roasted potatoes :)
Yes! Shake that booty! I will sit my plump butt down and eat this potato salad :)
Potatoessssssssssssss – now! Thx.
Again, OH. MY. GOODNESS.
Now about this booty dance, do I need to work in circles in any way, or just shake what my babies gave me?! lol
This made me laugh out loud and those potatoes look amazing! Glad to know other people do crazy things while cooking and eating…
The potatoes sound fantastic, and the salad looks divine!
Hey Joy, I’m new to your site and I’m lovin’ it! You are the most amazing photographer. I love your writing as well, sort of off the wall and right on! How refreshing you are.
this is my favorite way to make taters! i love the mustard on them, it crisps up so perfectly in the oven. these pictures are great – so clean and expansive. i love them. im not sure about eating frozen cupcakes – i dont think my wimpy front teeth could handle it! but then i am SURE i would manage.
thanks for gorgeousness as always!!
Major dreamtime! I just made breakfast and now you have me thinking about dinner!
Wholegrain mustard, I love you…
I’ve been all about mustard lately. It may have a little to do with trying to kick myself off my ketchup addiction, but I’m sure this dish will help me enjoy my “detox!”
This recipe looks just delicious and perfect!!!!
Um, damn tasty! I have never met a potato I haven’t liked … adding this to my MUST MAKE pile.
Joy you are hilarious! Thanks for the awesome looking recipe! I love new potatoes and I am always looking for a new way to make them.
YUM!
Wait a gosh darn second. Those potatoes look fabulous but what is that salad?! Edamame and avocado? Give me some of that! Mmm
You know, there are so many things to do with potatoes and yet I’m always hungry for more. Maybe because potato recipes can be so, um, bland. This sounds dinner-worthy.
yum! and yeah- whats with the salad??have you shared that before or should we be expecting it soon??? HOPE SO, it looks yummy!
JP
The potatoes look so so so good… but so does the salad with edamame and avacado!!!
Yay! The farmer’s market just started up hear I’ll be looking for recipes to use all this fresh produce in. :) I love spring!
Those look delicious! It doesn’t help that I am so hungry right now.
These are, hands down, my favorite potatoes. I make them any chance I can get!
This is one of those posts I had trouble reading at first, I was so busy scrolling through the pictures and had to go back. Just gorgeous, fun recipe. I love it.
I have a slight obsession with anything mustard. These are a must try for me! Have fun dancing!!
I always mute EHarmony commercials and Match.com commercials. They’re always on and so annoying!
When your done booty shaking and wearing head scarves, can you also tell me what kind of salad that is on the right hand side of the last pic?
I spied edamame and I’m in love.
LMAO @ muting eHarmony commercials. I definitely agree.
right!? thank you.
sounds like a delightful combination of flavors. btw my whole grain mustard and i are bffs.
I’ve been looking for a mustard-potato recipe for a while and these look amazing! Can’t wait to try.
Must be in the air….I have been doing a lot with mustard this past few weeks too :) They look delish and love the additional veggie combination.
what’s the salad? where does the avocado come in? is that the next post? do share, joy . . .
I love roasted potatoes with mustard and herbs. I have never tried them quite like this. Gonna do it!
I have everything I need for this. I think I’ll try them tonight, but roasted on the grill with salmon and asparagus. Perfect. Thanks Joy. :)
Your potatoes look so delicious and makes me wish I liked dijon mustard. But I might try this with a raspberry mustard instead because your photos are making my mouth water.
Enjoy your booty dancing and shakin’ your booty! There’s nothing more fun than dancing around the house expressing your joy…unless it’s eating cupcakes! :)
We love potatoes in this house and I’m always looking for new ways to do them. We typically do the garlic thing, or dill and occasionally the Cajun style but I’ve never heard of mustard potatoes! (I wonder if you can do ketchup ones like this, like ketchup chips but not…)
Now I can’t wait to try!
this is a must make for me, they look awesome and sound delicious. Job well done Joy…now go back to your dancing :)
I love this deliciousness!
Don’t be ashamed. Go ahead and dance! Just try not to bruise yourself with those slippery socks on.
Mmmm, lovely, Joy! I have a bunch of new potatoes I picked up at the farmer’s market this weekend and was looking for a good roasting recipe to use them up. Thanks!
Perfect for Meatless Monday. Thanks for sharing, Joy. Happy Monday :)
Dancing in slippery socks is the best exercise for the soul.
Those potatoes look yummy yum yummy Joy but what is that green goodness in the bowl beside them? That looks like a yummy edamame salad or something….looks yummy enough to dance over!
Yay, these look so yummy!! I have a packaged mix very similar to this that you can toss new potatoes in, but I’d so much rather make my own potato-bath-dressing. Can’t wait to try it! :)
We love roasted potatoes, but have never tried them with mustard. We will add this the next time. Beautiful photos and super recipe, can’t ask for more, but the side image of dancing and eating cupcakes was nice.
~Brenda
Awsome timing!!
We are planing a huge Crab bash (it’s a Baltimore thing) and I need to find easy sides to serve. This is perfect. Thanks!
Looks delicious, as always. Do you have a recipe for that lovely looking salad on the left? x
I have a sack of New Potatoes in the pantry as we speak…. and now I know exactly what to do with them for dinner tonight :) Thanks for the inspiration!!!
These potatoes look just perfect, they are on the menu list this week!
New potatoes have been popping up all over the place here in Denmark. The newest of the new potatoes are insanely expensive, and only get purchased by the most fancy smancy restaurants to be turned into marvelous culinary works of art. The older new potatoes eventually end up in the supermarkets, still expensive of course, but utterly delicious and so worth the wait.
Damnit, Spring is seriously just the BEST.
Enjoy your dancin’!
xxx
Sounds Delish! I want some now but instead for now I think I’ll dance around my kitchen too. I will get to the potatoes soon.
Love the looks of this dish, and was just wondering if you are going to post more detailed step-by-step instructions about the booty dance. I’m not very good at that sort of thing. ;)
i have never thought to mustard roast potatoes, but i’ve done brussels sprouts and it’s HEAVEN! i can only imagine how great starchy potatoes would be with it. yum!
These are fancy and I want some. Yum!
Potatoes and booty dancing? Count me in. Just saw and voted for you on saveur, so happy to see your wonderful site was nominated :)
Yum, I have people coming for lunch on Sunday and wanted something new to try so I shall definately be making this.
You’re hilarious! Can’t wait to switch up my old boring roasted potatoes!
What about the salad, is that edamame? Share or have you already?
Yes! I want to know about that salad!
the taters look great! anything with mustard, i am down for! i roast carrots and squash with a dijon glaze/marinade..need to put it on the taters like you did!
I don’t usually get excited about roasted potatoes, but these could change that!
I’ll have to wait until July to eat new potatoes when I travel to Europe. I have a feeling that this mustardy, lemony coating will do wonders for the rather average potatoes in the shops in Dubai. Off to grab my slippy socks and the mustard jar.
You just changed my potato plans for tonight!!! I was going to make a different kind, but after reading your post I decided to change the menu and am making these :-)
Go on dancing, eating cupcakes and writing great posts.
Ooh these look super. So easy to make and yet I can imagine them going well with lots of stuff.
Looks incredibly yummy!
Cor, these look like a perfect combo – and so easy too!
I’m thinking I’ll be doing this with some of those fingerling potatoes and perhaps a roasted or grilled turkey thigh. No headscarf though, but maybe in a flowy maxi-skirt….with my dancin slippers on……
These potatoes look great…one day you should show us how you practice your dance while eating cupcakes with scarf and slippery socks on… ^_^
I’m pretty sure these potatoes taste infinitely better when roasted while practicing booty dance moves. Yum.
Mmmm New Potatoes!! Ina Garten has a recipe very similar to this – I think she uses lots of sliced onions and grainy mustard too, as well as fresh parsley, olive oil, salt, pepper and just a touch of white vinegar. It really works well. I add a splash of maple syrup to it to bring out the sweetness of the roasted onions. I like the lemon zest in this one, though, it’s a nice change for potatoes!
Wow Becca, that sounds amazing, nice touch!
Love the final photo. Beautiful! And girllllllllllllll, that salad looks FRESH.
<3
Do you sing too Joy when you make your yummy potatoes? I almost always warble when I bake. Especially bread. The kneading I feel is enhanced considerably by my out-of-tune, dreadful, dreadful singing. I’m occasionally known to shake a little bit too. Shaking in the flour rather than my booty mind.
This looks and sounds amazing! I have to make as a side for dinner tonight. Thank you for sharing
This is awesome to combine mustard with roasted potatoes. You will certainly earn this after the intensive exercise!
