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

Did you know that 100 grams of orange sweet potatoes contain only 17 grams of net carbs?

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.

Hi! Do you need help to start Keto?

By Carine from Sweetashoney

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.

Instructions

  • 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.

      • That is wonderful! Thanks for sharing your option. Enjoy the recipes on the blog my friend. XOXO Carine.

    • Hi Elena, Sure you can! I used frozen spinach in this recipe. If you read the instructions further you will see that I cooked the frozen spinach into a frying pan with garlic and onion before garnishing the quiche. Enjoy! It is super yummy & healthy. Carine.

  1. I made this for my family for dinner tonight and it was so good! The texture of the sweet potato, spinach, and egg was great. Definitely will be making again as a healthier alternative to a quiche with a traditional crust!

    • Hi Danielle, I makes me so happy to read your comments. I am so glad you enjoy this quiche recipe and I hope you will make it again soon. I made with quiche many times and I also love to use different filling ingredient. I recently tried to subsititute the spinach by grated zucchini and bacon with parmesan on top. It was delicious.

    Wow! This looks so good! I’m vegan, so will sub out the egg mix with a tofu ricotta cheese and top with Daiya cheese shreds. Thank you Carine for the idea of the sweet potato crust!

    • Ooooh, can you pls share the tofu ricotta cheese mixture that you would sub in? Sounds amazing!

    • Hi, I am so happy to read your comment because I am always on the look for vegan options. I am not eating fully plant based but I love having at least a vegan meal per day. Your tofu ricotta cheese sounds amazing! Thank you for sharing here! Merry Christmas. Carine.

    • Hello! I love your vegan option sooo much! I will definitely try this next time. I hope you enjoy this simple quiche crust as much as we do 🙂 Merry christmas! Carine.

    Hi there Carine, As always I played around with this recipe. (Everything I cook.) I JUST last night used all my fresh spinach up BUT I always have fresh broccoli so I par steamed the cut up broccoli and left in a sieve to get as much fluid out. Not only did I not have any sweet taters but don’t care for them anyway. I also wondered about using regular taters too (LOVE THEM!!) but will wait to see how “Julia” makes out with them. I’m worried they might come out chewy enough; like baked to a crisp. SO, I sauteed onions, fresh garlic and mushrooms and will dump that and the broccoli in a regular crust. 360 for about 30″ huh?? Wish me luck and thanks so much Carine!!

  4. Hello lovely !I am sure it turns out great ! The best recipe are always the one we twist a bit. I am like you I can’t follow a recipe at 100%. I always like to change something 🙂 Thanks for your lovely comment and for testing my recipes. You are the BEST. XOXO Carine.
