Roasted Sweet Potato Quiche- A delicious twist on a traditional quiche with roasted sweet potatoes, onions, and lots of gruyere cheese.

I’m quite aware that not everyone has my sweet potato obsession. ‘Not sweet potatoes again” is a phrase often muttered by members of my family.

What’s not to like about a healthy food that’s naturally sweet? I just don’t get it. Especially considering how much pumpkin love there is. I find that sweet potatoes can be used in any recipe pumpkins can be used in, plus a whole lot more. They are more accessible than pumpkin during the non-fall months and they are easier to prepare. OK maybe not easier than canned pumpkin. But still.

Sweet potatoes are so versatile. They can be eaten plain, or in a variety of sweet and savory recipes. My personal trainer, who is perhaps the healthiest eater I’ve ever met, eats a sweet potato just about everyday. Totally plain. Just pops it in the microwave until it’s cooked, picks it up, in his hand, and starts chomping away at it. Not utensils needed, no salt or butter. Just the sweet potato. Wish I enjoyed eating food that plain.

My favorite sweet potato recipes are always savory. When I saw a recipe for Sweet Potato and Onion Tart in the October 2012 Southern Living Magazine, I was very intrigued. A tart (or quiche is a better term for this particular recipe) was one way I had never cooked sweet potato.

And let me just tell you, I think Roasted Sweet Potato Quiche might just be my favorite quiche ever. The sweet potatoes, along with some onions are roasted first to heighten their flavors. Some bacon is added which gives a salty contrast to the sweetness of the sweet potato and onion. Plenty of Gruyère cheese is used. Is there any better cheese for quiche? I don’t think so. Fresh parsley and rosemary round out the flavors. Oh how I love rosemary with sweet potatoes.

The mixture of sweet potatoes, eggs, and cheese tasted so fabulous I’m thinking that sweet potatoes would be delicious in omelet form too!

For more sweet potato cooking inspiration check out my Sweet Potato Pinterest Board. Over 320 sweet potato recipes pinned. Told you I’m sweet potato crazy! Maybe I’ll pin 40 more and make a different sweet potato recipe everyday next year. That may cure my sweet potato obsession!

Note: Gruyère cheese is a little on the expensive side- but it is so worth it. I really don’t think there is a less expensive cheese that comes close to matching its flavor. I used a refrigerated pie crust, but you could definitely make a homemade piecrust.

Oh! And I almost forgot! This new, blue tart pan (see the second picture) that I got with a removable bottom worked really great. The quiche just popped out in one giant piece. It was only about $10 at Target and it came in a bunch of different colors. Definitely a good buy.

A delicious twist on a traditional quiche with roasted sweet potatoes, onions, and lots of gruyere cheese.
PREP: 30 minutes
COOK: 35 minutes


  • 3 cups sweet potatoes, 1/2-inch cubed, (about 2 medium peeled)
  • 1 cup chopped sweet onion
  • 2 tablespoons olive oil
  • 1/2 teaspoon seasoned pepper
  • 1/4 teaspoon kosher salt
  • 6 slices bacon cooked and crumbled
  • 1 refrigerated pie crust
  • 2 cups shredded Gruyere cheese
  • 1 1/2 cups half-and-half
  • 4 large eggs
  • 2 tablespoons chopped fresh parsley
  • 1 teaspoon chopped fresh rosemary
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon pepper


  • Preheat oven to 425 degrees.
  • In a medium bowl, toss together sweet potatoes, onion, olive oil, seasoned pepper and 1/4 teaspoon salt. Spread in a single layer on a lightly greased jelly roll pan. Bake 15 minutes, or until sweet potatoes are just tender. Stir halfway through.They will get softer when the quiche is baking.
  • Let sweet potatoes cool to room temperature.
  • Remove pie crust from refrigerator and let sit on the counter for 5 minutes. Unroll the piecrust and fit into a pie plate or deep dish tart pan with removeable bottom. Trim excess pie crust from edges or fold excess and tuck it under. If tart pan has fluted edges, press the pie crust into the edges.
  • Line piecrust with a double layer of heavy duty aluminum foil. You can place pie weights or dried beans on top, but I found that a double thickness of heavy duty foil was enough by itself to keep the pie crust from puffing up while baking.
  • Place on a baking sheet and bake for 10 minutes. Remove foil and bake 5 more minutes. Let crust cool 5-10 minutes.
  • Reduce oven temperature to 350 degrees.
  • Add crumbled bacon to sweet potatoes and onions and place half of this mixture on top of piecrust. Top with half of cheese. Repeat layers.
  • Whisk together half-and-half, eggs, parsley, rosemary, salt and pepper and pour into piecrust. Bake in lower part of oven for 35 to 40 minutes or until set. Cool for 15 minutes before slicing.

    Dont let them get you down on your sweet potato obsession. I made the mistake of going oh their purple flowers are so pretty. Well they are…they also took over half my yard. So now we have 9000 football sized sweet spuds. Appreciate your site it will help me immensely.

    I too used butternut squash but also used the sweet potato. It was amazing. I wasn’t able to put all the egg mixture in but, it still turned out super.
    Thank you for posting. Best quiche ever!

  3. Even though I could only fit half the mixture it was still delicious! I also used butternut squash, pancetta and sage instead of the sweet potato/bacon/herbs in your recipe and it came out great. Oh and i used 2% milk instead of half and half and it was still amazing. I love sweet potato but didn’t have any on hand. I will try your suggestion and see how the pie crust does! Thanks for a great recipe!

      SO happy it turned out well! Butternut squash, pancetta, and sage sounds wonderful! I love the smell of sage this time of year. Nice to know you cut down the calories and it was still delicious.

      Oh no! That happens to me on occasion too. Next time try folding the excess crust back under so there is a double layer around the edges and press it so that it is really clinging to the top of the pan.

    Oh girl, move in with me and you will NEVER hear the words “not sweet potatoes again”! I guarantee I am probably even more obsessed with them than you are, and this quiche? To die for!

  5. Amy @ Elephant Eats

    Hehe. I definitely have food obsessions too 🙂 I would never have thought to add sweet potatoes to a quiche, but it sounds delicious!

  6. Erin | The Emerging Foodie

    Oh I absolutely share your sweet potato obsession! I actually like them totally plain like your trainer… funny! This look deliiiiiicious!

      Ok, something happened and it forced to post a comment before I finished typing it. 🙂

  9. This recipe sounds interesting! I have also used sweet potatoes for a breakfast hash type dish that was super yummy…Cut sweet potato into small cubes and brown in a little oil/butter, add onions if you like…When the sweet potatoes are almost cooked, break an egg over them and cook until set; I like to leave the yolk runny to break over the mix once on my plate. The only seasonings i used were salt and pepper 🙂

      That sounds fantastic Tiffany! Love the way sweet potatoes taste with eggs and I like the yolk a little runny too!

  10. Samina | The Cupcake Confession

    That blue tart pan is just TOOOO CUTE!!!! I agree with you, I find it soooo difficult to eat food that tastes kind of…bland! there needs to be flavor somewhere so I can definitely not think of eating a sweet potato or any veggie without something to go with it! And then there’s this lovely quiche! The perfect solution to my problem!!! It’s soooo amazing! I love the browned top!!! Yum!

      Thanks Samina! I actually picked the blue pan with this recipe in mind. Love blue and orange together!

  11. I share your obsession for sweet potatoes — I can’t get enough! I love them in pie, mashed, roasted, you name it. This quiche looks to die for! If this were in front of me, I would eat a giant slice!

  12. I am a big fan of sweet potatoes too so this quiche looks fabulous! Perfect for a weekend brunch. Love the blue tart pan too! Have a great weekend Christin!

  13. Ashley | Spoonful of Flavor

    Another amazing recipe, Christin! I love sweet potatoe and quiche so this is the perfect combination for a weekend brunch.

  14. Consuelo @ Honey & Figs

    I feel your pain, everybody in my family HATES sweet potatoes :(( But these look so lovely that I’m definitely not missing them… I guess I’ll try to make mini quiches or something instead 😉
    Happy weekend!
