Here’s how this is going to go down, my friends: whole roasted onions, roasted with olive oil and butter, roasted with rosemary, roasted whole, roasted to sweet submission.
It’s cold. I mean… really cold. Here’s our chance to crank up the oven, throw these onions inside and lean against the oven door as they transform from sharp and bite-y to soft and sweet. And while we’re at it, here’s how to roast any vegetable.
Oh wait… you might be one of those people who think they don’t like onions. I’m here to tell you that you’re wrong. You exclusively like whole roasted onions.
If you’re feeling fancy you might want to try this recipe for Ottolenghi’s Miso Butter Roasted Onions and Garlic! It’s like a savory onion candy. 10/10 recommend.
Roasting is magic. It’s as simple as that.
These roasted onions, tops removed and toasted in their jackets, become soft, smooth, sweet, and almost spreadable. I served mine along side thin cut pork chops and salad because I’m really good at living.
Happy Winter and happy roasting!

I loved this recipe. Roasted them tonight for just a little over the suggested baking time and they turned out absolutely delicious.
Such an easy and effective way to cook onions.
This recipe is going to become a regular whenever I cook a roast.
Thank you so much :-)

This is fabulous….but that pan looks like a nightmare to clean…I think I’ll slip some parchment underneath when I try this…

A question, please – do you leave the root end intact or cut that off when you cut off the tops ?
joythebaker
I leave the root end intact and remove the root end and skin after baking.

The best part about this recipe (and doing it while I write) is *no peeling of the onions*. Gold, right there, let alone all the rest of the goodness!

These were very good but took a LOT longer to cook than the recipe called for. I used the smallest onions I had but they were still likely bigger. I’d say it took at least an hour and 15 minutes and could have used a bit more.

Yes, the longer bake time sounds much better. Thought of that when reading it over. Melted onions. Yum.
