While it is easy to slice and serve in a place, it does not hold well in your hands. It is more similar to a crustless spinach quiche in which you would have had some sweet potatoes.

It makes a very easy healthy dinner that everyone loves.  All you need to make this simple sweet potato crust quiche or easy spinach quiche crustless are:

  • Orange sweet potatoes – peeled, thinly sliced
  • Spinach – fresh or frozen
  • Eggs
  • Dairy-free milk or regular milk as you like
  • Cheese – optional if you are on a paleo diet you can omit the cheese on top

How many carbs in a Sweet Potato Quiche

Hi! Do you need help to start Keto?

By Carine from Sweetashoney

While it may seem a lot for someone on a keto diet, it is a low-carb vegetable for anyone looking to decrease their carbs.

It should be reminded that a regular pastry crust made of white wheat flour contains around 40g of net carbs. So this sweet potato crust quiche is a good start to half your carbs by 50% in an easy spinach quiche recipe.

Of course, it is recommended to use a round ceramic tart dish to make this quiche recipe. It is easier to slice and serve.

How to store your spinach quiche?

This sweet potato crust quiche is an easy sweet potato recipe to make-ahead and reheats the next day. You can store your recipe in an airtight container in the fridge for 3 days.

The first option, reheat in the microwave for 2 minutes. Otherwise, bring back to the oven at 350F (180 C) for 8-10 minutes.

Finally, you can freeze your quiche in single portions or whole and defrost in the fridge the day before serving and reheat in the oven.

  • 1 Onion finely chopped
  • 14 oz Frozen Spinach

  • Preheat oven to 360°F (180°C).
  • Grease a 9-inch (24 cm) round ceramic quiche dish with butter or coconut oil. Set aside.
  • In a frying pan, under medium heat warm the olive oil.
  • Add garlic and onion. Fry until fragrant and golden brown. Stir often to prevent the spices from burning.
  • Add the frozen spinach cover and reduce to low heat. Cook until the spinach is cooked through, soft and tender - about 15 minutes. Adjust with salt and pepper to taste.
  • Meanwhile, peel the sweet potatoes then use a mandoline Vegetable Slicer to finely slice the sweet potatoes. 
  • Arrange the slices on the pan making sure that you cover all the bottom leaving no empty space. For the border, cut in half the sweet potatoes slices to create a 'flat' bottom it will hold better and create a beautiful crust border.
  • Prebake the sweet potato crust at 180°C for 15 minutes.  This is optional, you can also add the spinach and egg filling directly and bake your quiche - make sure you cover the dish with a piece of foil to ensure the quiche is cooking at the same speed. I prefer to prebake the crust to avoid using a foil - up to you.
  • Spread the cooked spinach all over the pre-baked sweet potatoes crust. Set aside.
  • In a medium mixing bowl beat the eggs, almond milk, and nutmeg. Adjust with salt and pepper if desired.
  • Pour the egg mixture onto the quiche.
  • Add a handful of grated cheese on the top of the quiche, if desired. If paleo, sprinkle almond meal on top instead of cheese, it gives a delicious crisp on top.
  • Bake for 25-30 minutes or until the sweet potatoes are soft and the cheese is grilled. 
  • Serve immediately. 
Pan: Don't use a loose bottom pan or the egg mixture will run away from the dish.
Storage: Store well in the fridge for up to 4 days. Simply leave the quiche in the pan and wrap it with plastic film to prevent the quiche from drying out. Remove in the microwave or hot oven until hot.
Dairy-free option: Replace cheese with 2 tablespoons of almond meal. Sprinkle on top and bake until crispy.

    This was one of the best healthy meals I’ve ever made! I have gotten more ingredients to make it again because my husband and I just enjoyed it so much. It is both a light but filling dinner. One pie was good for two meals for us ad my hubby loves his food.

    • The recipe is not tagged at whole30, none of them on my blog are and as mentioned in the recipe card, the cheese is optional of course! Enjoy the recipes on the blog. XOXO Carine.

    • Yes sure! Freeze in an airtight container, defrost the day before and rewarm either in the microwave or oven. Enjoy the recipe. XOXO Carine.

  3. Hello
    I’m. new to this post. Can I get away with using pre boiled sweet potatoes and slice them up for the crust. I don’t have a mandolin

    • The sweet potato slices need to be raw/uncooked or it will get too soft when baked. If you don’t have a mandoline, use a sharp knife, slice as thin as you can and even if it is thicker than my slices it will work! It will simply request about 10 minutes extra baking. Enjoy the recipe ! XOXO Carine.

  4. hi from Switzeland-just found this recipe and your blog on Pinterest while looking for some ideas for dinner.. pinned your blog for good. will make a vegan option tonight. thanks for the inspo!

    • Awesome ! Welcome on the blog. I am so happy to have more people from Europe here. I am French and visit Switzeland last year, what a beautiful place! Enjoy the blog. XOXO Carine.

    Hey there, quick question

    Do you think this would taste good without cheese? I’m lactose intolerant and I live in Lebanon so there aren’t really any fake cheeses/cheese alternatives.


    • Of course! My little girl don’t like melted cheese and we replace that by ground almonds or crushed seeds to add a little crunch on top! Delicious ! Enjoy the recipe and the blog. XOXO Carine.

    I made this this week and it’s yummy however my base was really soggy. Not sure if this was because of the potato’s (which I pre baked ) or the water from spinach? Is there anything I can do?

    • It should not be soggy and it is the first comment I read about that. If you perfectly cook your spinach in the saucepan all the water from the spinach should be out so it won’t come from here. The crust gets dry too after beeing pre baked so same, not a problem. If it was the egg filling that wasn’t set it means that you may have overcooked the quiche, or too low temperature? Next time, make sure you cook very well the spinach that is the only thing that could make the quiche runny – like any other quiche actually. The extra liquid from spinach dissolve the egg batter making it difficult to set. Enjoy the recipe. XOXO Carine.

    • Cheese is optional but if used add 1/4 cup of any sort of cheese. Feel free to use a combo of cheese, ratio you like or only edam or only cheeddar. Anything taste delicious. Enjoy the recipe, XOXO Carine.
