Wow these back-to-school mornings are a hustle! After 18 months with everyone working and schooling at home, I had forgotten how crazy weekday mornings can be when chilling in your PJs all day wasn’t an option. So I have been busting out all of my best meal prep tips and tricks to make these busy fall mornings a little less hectic.
Quiches are one of my favorite healthy make-ahead breakfasts. Full of protein from eggs and super easy to veggie-load. Plus, it is simple to make and great to store in the fridge so you can reheat and eat quickly on those mornings when the snooze button was hit one too many times.
This Crustless Spinach Sweet Potato Quiche is easy to make now and enjoy for days. Baked to perfection in about 25 minutes, this is the perfect savory and filling breakfast. Naturally gluten free and vegetarian, this delicious quiche serves 8, so it works well for serving to a crowd with lots of different eating styles!
Suggested adaptations
- Make it dairy-free by using your favorite plant-based milk and omitting the goat cheese.
- Add more veggies. Bell peppers or mushrooms would be a delicious addition to this sweet potato quiche.
- Use a different cheese. Mozzarella or cheddar would also be great in this breakfast recipe. Use about 1/2 a cup of shredded cheese on top of this vegetarian quiche.
- Add meat. If vegetarian isn’t needed, throw some cooked bacon, chopped ham or cooked breakfast sausage into the mix.

How to store this vegetarian quiche
Once this sweet potato quiche is done cooking, let it cool completely before covering and transferring to the fridge. You can store it in the pie pan covered in foil or slice and store individually in air-right containers. It should be good for 3-4 days in the fridge.
Tips for reheating this crustless quiche
I like to reheat this quiche by the slice in my air fryer. Use the reheat setting and set temperature to 375℉ and warm for about 5 minutes.
You can also reheat this recipe in the toaster oven/oven. 375℉ for 5-7 minutes. – but keep an eye on your oven and check after 5 minutes. You want the eggs to be warm, but the top of the quiche can easily burn in the toaster if left in too long.
The whole quiche can be rewarmed in the oven. Place the cold quiche covered in foil in the cold oven. Turn your oven on to 350°F. Let warm in the oven for about 25 minutes.
You can also microwave this recipe, but I don’t recommend microwaving eggs, as it can change the texture and turn eggs rubbery easily.

Crustless Spinach Sweet Potato Quiche
Ingredients
- 1 Tablespoon olive oil or avocado oil
- 1/2 cup chopped yellow onion, can sub scallions
- 2 cups diced sweet potato, cut into 1/4 inch dice
- 2 cups loosely packed spinach, roughly chopped
- 1/2 teaspoon course salt, divided
- 1/2 teaspoon paprika
- 1/2 teaspoon garlic powder
- 6 large eggs
- 1/2 cup milk of choice
- 2 ounces goat cheese, cut into chunks, can sub feta cheese
Instructions
- Preheat oven to 350℉ and grease a 9-inch pie plate.
- Heat oil in a large skillet over medium-high heat. Add onions and cook for 2 minutes. Add diced sweet potato and cook, stirring occasionally, until pieces are starting to brown and slightly tender, about 6-7 minutes.
- Add chopped spinach and stir in with the potatoes and onions. Cook until spinach is starting to wilt. The vegetables don’t need to be all the way cooked through yet since they are going to cook more in the oven.
- Season with 1/4 teaspoon of salt. Add vegetables to your prepared pie pan and spread into an even layer.
- While vegetables are cooking, whisk eggs, milk, garlic powder, paprika, and remaining 1/4 teaspoon of salt in a large bowl. Pour egg mixture over the vegetables in the pie pan and give the pan a little shake to even everything out. Crumble the goat cheese over the top.
- Bake until set and lightly golden brown on the top, about 20-25 minutes. Allow to cool for 10 to 15 minutes then slice into wedges. Serve warm.
How much onion and how many does this serve?
Hi there! Excited to make this. I read about cooking and and reheating but any issue with say prepping everything in morning but leaving in fridge and waiting to bake? The only thing I can think is temp of veggies…
I haven’t tried but I cant see a reason why that wouldn’t work! Please let us know how it goes if you try it out!
One of my favorites!
So glad to hear that, Grace!!
I made the crustless spinach sweet potato quiche today. I used a 10” pie plate, added a yellow bell pepper, used a large sweet potato, and a red instead of yellow onion. I baked it in a countertop convection oven for 45 minutes. It was perfect! I loved it! I ate it for lunch. I will make it again with mushrooms and other vegetables, as well. A great recipe, thank you!
Yay! So glad you enjoyed it so much, Melinda!
I just sent you a review of your quiche. I forgot to add that I did not cook the veggies before baking except the sweet potato. I cooked it in a microwave after scrubbing the sweet potato, piercing it with a fork front and back, oiled it with olive oil, then cooked it for 8 minutes in the microwave on a plate. I also did add spinach to the other ingredients, uncooked. I added the 1 tablespoon oil to the veggie mix with the 1/4 tsp of salt and mixed it together before adding them to the greased pie plate.
Oh thanks for coming back and adding this note!
