Sweet Potato Crust is a Must

December 27, 2015 | By | Comments (88)


Sweet potatoes might actually be my favorite ingredient. They’re incredibly versatile, naturally sweet, loaded with nutrients and fiber, and low in calories. Really, what’s not to love?

Whether perfectly roasted, made into gnocchi, whisked into a pancake batter, or sliced into chips, this humble ingredient continues to reach beyond my expectations with each dish I try. Well, once again, it did more than impressed me, it wowed me!


The whipped egg and milk combination sunk down perfectly in between the slices of sweet potatoes to create a perfectly tender crust (that holds together) on the bottom with a chip-like consistency around the edges. The filling is from our Spinach and Feta Quiche.

2 medium sweet potatoes
1 teaspoon canola oil
1 (5-ounce) bag baby spinach
1/2 cup 1% low-fat milk
1/2 teaspoon kosher salt
1/4 teaspoon freshly ground black pepper
1/4 teaspoon crushed red pepper
4 large eggs
2 large egg whites
1.5 ounces feta cheese, crumbled



1. Preheat the oven to 350°, then peel and slice sweet potatoes. I sliced mine using a mandoline, but a knife works great as well. The mandoline speeds up the process significantly and gives you even slices. Coat a pie dish with cooking spray, then fill the bottom of the dish with a layer of sweet potato slices. Cut the sweet potato rounds in half and fill around the edges of the pie dish; round side facing up. Once the entire dish is filled, coat one more time with cooking spray. Bake for 20 minutes. Turn heat up to 375°.


2. For the filling, heat a nonstick skillet over medium heat. Add spinach; sauté 3 minutes. Remove from heat; cool.

3. Combine milk and next 5 ingredients in a bowl; stir with a whisk. Arrange spinach mixture in crust; pour egg mixture over spinach. Sprinkle with feta. Bake at 375° for 35 minutes. Let stand 5 minutes; cut into 4 wedges.

    If you want to print, follow the link to the Spinach and Feta Quiche recipe. Just make a note of how to make the crust. It was very simple.

    This is just the recipe I’ve been looking for! Question: Which mandolin do you use? I’ve been struggling to find one that will slice sweet potatoes into thin rounds. thank you!

    Looks like a great recipe. Too bad lots of the commenters are a bit whiney…

    This isn’t a crust – this is a vegetarian way of substituting a real crust.

    Thank you Sharon for your comment. I’m frustrated when there is no “Print” option. What’s the big secret?
    Why not respect your “customers”.

    The recipe doesn’t call for onions, yet the video showed onions. I made it with onions and added mushrooms. I also use halvarti cheese (cause that’s what I had). It’s in the oven now. I also noticed that the video showed yams, not sweet potatoes. I’m not a fan of yams so I stuck with sweet potatoes. Can’t wait to try it.

    The above recipe doesn’t include the onion, which is very important.

    Sugar content would be nice. Many of us need to have the “sugar” listed.

    Please, what is the size of the pie dish?
    Also, if i cook it the night before and reheat it the same day, would it still look and taste fresh?
    Thank you

      Hi Monica,

      I calculated calories myself and I believe this nutritional information is for pieces 1/6 of the quiche. Hope this helps! 😀

    […] I’ve been wanting to try this next recipe for a while and so glad I did! Spinach quiche with sweet potato crust. It was really easy to make. I kept it in the fridge and reheated it in the oven when we had it for dinner during the week. Sweet potato, egg, spinach, feta and crushed red pepper flakes work very well together!http://simmerandboil.cookinglight.com/2015/12/27/sweet-potato-quiche-crust/?crlt.pid=camp.H3YGeKOY5w… […]

    I sautéd some garlic and Vidalia onions and added that to the spinach….also added more spinach. Mixed the eggs and almond milk with crumbled feta and baked….YUM!

    We truly enjoyed this BUT needed more. We will make again with minced garlic added to the milk mixture. Thinking adding Rosemary to the sweet potato crust might be nice. Possibly add pinenuts for crunch. Just needed a little moe “oomph” for my family.
