Rosemary Potato Frittata with Diamond of California Nut Crust

Hello my friends!  We are well on our way into the cozy season – perhaps my favorite time of year – when my oven is always on and I roast or bake absolutely everything.  

Every dinner is a combination of vegetables roasted on a sheet pan combined with eggs of some sort.  Do you eat eggs as enthusiastically for dinner as I do?  They’re a majority of my diet mostly because they’re always in my baker’s fridge and it’s such a comfort. 

The most comforting combination of roasting vegetables and egg is, of course, a quiche – the food of truly any time of day!  Today we’re adding layers of thinly sliced potatoes and fresh rosemary and a bright apple and walnut topping.  Trust. It’s good stuff. 

Today’s quiche recipe is made in partnership with Diamond of California to celebrate their new nut pie crusts! A few weeks back we made Dark and Stormy Pie with the Diamond of California’s Pecan Nut Pie Crust (major win!), and today we’re exploring a savory version of these versatile crusts! 

Here’s what you’ll need for this deliciously easy quiche: 

• Diamond of Californias Walnut Nut Crust. The crust is ready to go and super easy to use, crisp, and deliciously nutty in flavor.  It’s also great in sweet preparations too. See: Dark and Stormy Pie. 

•  Six large eggs and a cup of half and half. 

•  Russet Potatoes, shallots, and fresh rosemary. 

•  Apple, walnut, fresh herbs, and walnuts for a fresh sweet and savory topping to the quiche. 

Start by peeling and very thinly slicing the potatoes. Slice carefully, we’re going for thinner than 1/4-inch – as thin as we can slice them by hand, really.  

Thinly slice shallots as well.  Layer in a medium bowl. 

Generously sprinkle the potatoes and shallots with sea sat and crushed red pepper flakes. 

Sprinkle with freshly torn rosemary leaves. 

The Diamond of California Walnut Nut Crust has a hint of rosemary, so we’re adding an additional layer of herb. 

Crack six large eggs into a medium bowl. 

Whisk in about 1 cup of half and half until the yolks and egg whites are well incorporated into a cool custard. Season well with sea salt and more crushed red pepper flakes. 

Time to unveil the crust! The crisp Walnut Pie Crust is ready to fill, so this quiche is a breeze!

Before filling the Walnut Nut Crust, toss together the seasoned potatoes, shallots, and rosemary. 

Begin to layer the potatoes in the pie crust. It doesn’t have to be perfect or packed in. 

Sprinkle generously with grated parmesan cheese. 

And cover the potatoes with the egg mixture. 

As the quiche bakes, the parmesan cheese will brown to golden, the potatoes will roast and soften, the crust edges will crisp and the eggs will bake to firm.  

It’s the most delicious way to quiche. 

I love a sweet and savory combination so I added an apple gremolata topping: diced apples, thinly sliced shallots, parsley and herbs, diced walnuts, and parmesan cheese.  It’s a sweet and savory flavor bit that’s really nice compliment to the salty savory quiche.
