Why you’ll love it: If you haven’t made a quiche with a sweet potato crust, it’s time to give it a try! This bacon cheddar quiche is a healthier alternative to a traditional quiche, plus it packs more flavor. If you love quiche but want to make it more nutritious and/or gluten-free, this quiche with sweet potato crust is the perfect solution.

You guys know I’m pretty loyal to my mom’s cornmeal crust when it comes to quiche. The crispy texture is perfect for a rich quiche. However, I’m always looking for ways to make my recipes a bit healthier.
I’ve been seeing the idea of a sweet potato crust floating around Facebook and the internet and I knew I had to try it. I love the idea of a healthier and gluten-free version of quiche, plus I’m crazy about sweet potatoes. And dare I say, it’s easier than making a traditional crust?
If you don’t have a mandoline, it might be slightly more time consuming, but I’d definitely advise you to buy a mandoline, and not just for this recipe. A mandoline is such a great tool to have in your kitchen!

Bacon Cheddar Quiche
Not as rich as a quiche made with pastry. Quiche alway seems like a bit of a splurge with the pastry crust because after all, pastry is usually made with butter and white flour. You’ll love that the crust in this quiche is made with sweet potatoes, making it nutritious instead of merely adding calories and fat. Another bonus is that sweet potatoes are tasty, too!
Adaptable. You can adapt this recipe to include any quiche filling you enjoy. Make this recipe vegetarian by omitting the bacon. Try Swiss cheese or another favorite cheese instead of sharp cheddar. Substitute other vegetables for the spinach. Use egg whites instead of whole eggs.
Reheats well. I love this quiche because it’s so great leftover. Make a quiche (or two!) on the weekend and you’ll have breakfast or lunch covered for most of the week. Each slice contains a good amount of protein (13 grams) and is less than 200 calories.

I garnished the quiche with fresh chives because my chive plant is always out of control and I love the mild onion/garlic taste (but the chives are totally optional).

Refrigerate/Freeze: Allow quiche to cool to room temperature. Refrigerate in a covered container for up to 4 days or freeze for up to 3 months.
Reheat: Gently reheat the baked quiche in the microwave with 50% power until warmed through.

Bacon Cheddar Quiche with Sweet Potato Crust

Ingredients
- 2 medium sweet potatoes
- 6 ounces center cut bacon, cut into small pieces
- ½ cup diced onion (about 1 small yellow onion)
- 6 ounces baby spinach
- 6 large eggs
- ½ cup whole milk
- ¼ teaspoon kosher salt
- ¼ teaspoon freshly ground black pepper
- ½ cup grated extra sharp cheddar cheese (about 2 ounces)
- chives for garnish, optional
Instructions
- Preheat the oven to 350°F. Spray a 9-inch pie plate with nonstick cooking spray.
- Peel sweet potatoes and slice very thinly, using a mandoline if possible. Layer sweet potatoes into pie plate, overlapping to completely cover the bottom of the pie plate. To create sides, trim the sweet potato slices so they are flat on one side and continue to line the edges of the pie plate, overlapping slices. Continue this process until the pie plate is completely covered, 5 to 7 layers thick. Spray again with nonstick cooking spray or olive oil spray.2 medium sweet potatoes
- Bake sweet potato crust for 20 minutes.
- Meanwhile, fry chopped bacon in a large skillet over medium heat until browned and crispy. Remove bacon to a paper towel-lined plate, reserving 1 tablespoon of bacon grease in pan. Keeping heat on medium, add onion to bacon grease and cook until translucent. Add spinach, cover for 1 to 2 minutes, and then stir until spinach is wilted.6 ounces center cut bacon, cut into small pieces, ½ cup diced onion, 6 ounces baby spinach
- In a medium-sized bowl or large measuring cup, whisk eggs and milk with salt and pepper until well-combined.½ cup whole milk, ¼ teaspoon kosher salt, 6 large eggs, ¼ teaspoon freshly ground black pepper
- When crust is pre-baked, remove from oven; increase oven temperature to 400°F.
- Carefully arrange the spinach/onion mixture in the crust. Sprinkle cooked bacon on top of spinach; add the cheese in an even layer. Pour the egg mixture over spinach, bacon and cheese. If you have too much egg mixture, discard or save to make scrambled eggs later. The amount you need will depend on the size of your pie plate and how thick you made your crust.½ cup grated extra sharp cheddar cheese
- Bake at 400°F for 25 minutes or until eggs are set in the middle. Cool for 5 minutes before slicing and serving.
Notes
- Pro tip: For a crispy cheddar top “crust”, sprinkle additional shredded cheddar cheese on top of the quiche before baking.
- Vegetarian: Omit bacon, fry onions and spinach in 1 tablespoon olive oil.
- More variations: You can choose alternative fillings. Instead of bacon, try ham or sausage. Different vegetables can be used as well, such as asparagus, broccoli, mushrooms, and so on.
- Storage & reheating: Cool completely before storing. Leftover quiche should be refrigerated in a covered container. It will keep for up to 4 days or frozen for up to 3 months. To reheat, microwave at medium power until heated through.

This is absolutely gorgeous! I don’t eat a lot of potatoes these days, but when I do, sweet potato is my choice. I love everything about this recipe and I love your video!
Thank you, Shelby!
I love adding sweet potato to dishes! The crust sounds yummy!
Rachel, I just made your quiche this morning and this recipe is by far one of the best quiches I have ever made. I wasn’t sure if the sweet potato crust was going to turn out, but it adds so much more favor. I also didn’t have onions and I like spicy foods, so I added jalapenos to it instead. The only issue that I had, was that I had to add about 10 more minutes to the cooking time because the middle wouldn’t cook all the way through. But EXCELLENT job with this! I will be sharing this with my friends and co-workers. :)
Oh I’m so happy to hear that, Toni! This comment made my day! Loving the jalapeno addition!
Have you ever made this in advance and re-heated? What about freezing it?
I have reheated leftovers for breakfast but not the entire thing. I don’t think it would freeze well, potatoes typically don’t freeze super well and it would probably get a little watery. I hope you love it!
I made a variation of this for dinner. I had to use soy instead of reg. milk but still turned out fine. I didn’t use bacon but added cooked breakfast sausage and b/c I can’t have dairy did not add cheese. It was very good!!! I realized I didn’t add as many pieces of sweet potato as recipe and next time I will be sure to add more. So good. Thanks.
So glad you liked it! Thanks for taking the time to come back and leave a comment about your experience and changes! :)
I love this recipe so so much! I have made tons of recipes for my boyfriend over the years and this is the ONE recipe he always asks for. Well done!
So glad you btoh like it so much! Thanks for taking the time to come back and leave your feedback!
I was a bit skeptical about the sweet potato crust (don’t get me wrong I love sweet potatoes) but my husband and I had this last night for dinner and we both decided it was a KEEPER (our slang for a meal we would eat again) Thanks for the great recipe.
Oh I’m so glad to hear you liked it! It makes me so happy that it was a keeper for you guys! Thanks for taking the time to come back and let me know.
oh my god Rachel, this looks amazing!!!! I’m currently scouring for brunch dishes for the weekend and this just jumped to the top of my list xo
Not only does this sound incredible, but WOW-the photos are gorgeous! :)
Thank you SO much!
That sweet potato crust looks fabulous!
Thanks Medha!
