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.

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

  • 2 Sweet Potatoes medium size orange, peeled, finely sliced
  • 1 tablespoon Extra Virgin Olive Oil
  • 2 Garlic Clove finely chopped
  • 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.

    • I am sure it will! You may have to add 2 more egg white to balance the loose of liquid if you remove egg yolk tho. Enjoy the quiche ! XOXO Carine.

    Thank you so much for the recipe and especially for adding metric measures! I added 250g of wild salmon and it was delicious!

    • great idea on the salmon! we try to incorporate a lot of salmon for our cholesterol issues (hereditary)…did you cook it first??

    • My pleasure! Enjoy the recipes on the blog. I am vegetarian so I don’t eat fish but I am sure others will love to try your recipe ! thanks for sharing ! XOXO Carine.

    Loved the quiche. Always trying to serve healthy meals that are lower in calories and carbs. Thank you for your recipe. The sweet potatoes worked so well. I had selected the recipe and got busy at dinner time. My husband volunteered to make it. He is not a good cook but this was so easy that even he could make this without a problem.

    • The most beautiful comment on earth! When husband are in the kitchen it is big YEAH 🙂 I am so happy you enjoyed the quiche and he can’t cook for you. Amazing! Thanks for testing my blog recipes. XOXO Carine.

    • Of course! If you are on a low carb or keto diet I would recommend turnips or jicama for sure. I made this recipe with swedes once, it cook slightly longer to cook tho – I recommend to precook the crust longer until soft before adding the spinach filling. Enjoy the recipe. XOXO Carine.

      • I was also thinking maybe squash?? Our supermarket often sells it cubed and ready to go. I wish they did for sweet potatoes as well! LOL! I’d make the dish even more (I’m always crunched for time!)

  3. Hello! I am not a good cook, but I am on dinner duty! 🙂 I have a glass round dish and wonder if I have to adjust the cooking time or temp because the pan is glass and not ceramic? OR do you not recommend using glass at all?

    • Hello! Don’t worry it will be fine with ceramic or glass. Both cook food pretty much the same way. My advice, check the filling when it is set it is cooked 🙂 Let me know how it goes! Enjoy the quiche. XOXO Carine.

    • Hello! Any usual quiche filling will work well like zucchini slices, broccoli pieces – steam them before and let cool down before adding to avoid adding extra mositure – a combo of mushrooms, spring onion and red capsicum. Enjoy the recipe. XOXO Carine.

    Made this tonight – a friend posted it just as I was looking for a meatless dish to make tonight…I loved that I only needed a few ingredients! It was delicious! My only issue was the cooking time – It took about an hour to really cook through. The only thing my husband and I can think of is that I didn’t drain the spinach well enough? Thoughts???

    Looking forward to perfecting my technique and serving for a family dinner in April!
    P.S. I used lactose free milk and added Valencia orange peel spice to the quiche mix and I use Lemon Olive Oil – it all meshed together beautifully!!

    • Hello! It should take so long at all ! is that your filling that wasn’t set or the crust that was still soft? If it is the filling it defo comes from too much liquid. I cook my spinach in a fry pan before adding them on the pre-baked sweet potato crust and there is no water left after cooking them. May be cook the spinach longer to evaporate the liquid before spreading on the crust? Love your spices and oil choice!Sounds amazing for extra boost of flavors. Thanks for sharing and testing my recipes ! XOXO Carine.

      • 5 stars
        Yes – I used the lemon olive oil to saute the spinach and so that probably added a ton – that is how I like to make my fresh spinach. Trying again today to bring to a family who is in need of meals at a difficult time. Going to make sure I drain it well!! I’ll drain in a sieve and pat with paper towels as well. I’ll keep you posted!

    Can you use fresh spinach in this recipe! We don’t have whole leaf frozen spinach here. How much would it take. Thanks

    • Sure you can. I do use fresh spinach most of the time. For this quiche size you need 400 g of fresh spinach – trim the spinach leaves – remove feet and chop finely before cooking in the pan. Enjoy the recipe ! XOXO Carine.

    I’m wondering what are the best kinds of cheese to use on this dish. I have shredded mozzarella and a Mexican blend. Do you think either one of those will work fine? I also have grated Parmesan.

    • Hello! Honnestly any kind of hard cheese works well in this quiche. I love shredded mozzarella because it melt really well and create cheese strings when super hot from the oven. But it is also a very bland cheese. For extra boost of flavor I would recommend grated parmesan, emmental, cheddar or even feta (feta and spinach is AMAZING but it doesn’t makes strings as mozzarella does, so maybe a combo of too :). Let me know what you try and if you love it ! XOXO Carine.

    Caribe. I don’t know you, but I love you. I came upon this by accident (or maybe not). I bought a ton load of spinach on sale yesterday. Washed them and I’m sitting on my sofa trying to figure out what to do with all this spinach. Here comes my ‘sweetashoney’ angel Carine. You see, I’m always buying sweet potatoes, but all I do is bake them or make a pie. This is perfect for me because I’m trying to stay away from regular pie crusts. What a genius idea. Thanks for sharing. Nothing happens by chance.

    • You are so lovely ! I am a HUGE spinach lover so search the blog for ‘spinach’ and you should find plenty of easy healthy recipes to use those lovely spinach you bought 🙂 Enjoy the recipes on the blog! XOXO Carine.

    So yummy! Today i ended up mixing spinach and raimbow chard and bacon as my filling. And used regular potatoes because its all we had on hand :/ but still just as delicious as the original recipe!

    • Love your recipe option! Looks so good as well. Thanks for following the blog nd testing the recipe I post here. Talk to you soon! XOXO Carine.

    • Hi, Sure you can, if you finely chop your trim kale leaves it won’t be a problem. Use same amount as spinach. Enjoy the recipe. xoxo Carine.

      • 5 stars
        Ha ha, I thought you were responding to me. It was from previous question regarding substituting kale. So, should I pre cook the kale and squeeze before making the quiche?

        • Hi, Yes I would pre cook the trimmed kale leaves and squeeze out any water from the vegetables before using it into the quiche. I would also chop finely the cooked kale to make texture tastier. Enjoy the quiche! XOXO Carine.

      • Wow, thank you for your quick reply I love your style and dedication to clean eating. Going to make this with a roasted beet salad.

    This quiche is amazing !! what a great idea substituting crust with sweet potato. It was a huge hit in my household.

    . I am really interested in your Vegan Recipes. I am trying to get my mother to eat more vegetables.

      • hi for the sweet potato crusted spinach quiche what is the difference in taste appearance and texture as far as eggs and cheese for vegan and nonvegan?? is there any beside the obvious difference of being different things??

        • Hello! I would love to help you out but I am not sure I understand well your question. This recipe is not vegan as it use eggs and cheese. Feel free to replace the filling with a vegan filling using my chickpea flour frittata recipe here. Enjoy the blog recipes. XOXO Carine.

    This is the first time I have run into your Recipes. I enjoyed reading about them all. How do I go about requesting a copy for me and my son..

    • Hi, I am so glad you love the recipes on the blog ! don’t have a cookbook to sale online. All my recipes are accessible for free on this blog. Enjoy them ! Carine.

  13. Hi Carine,

    thanks for the lovely recipe! Do you think this would work with “normal” potatoes as well as I have some picky eater around here who’s not too fond of sweet potatoes (and: I know! how can you not love them?

    • Hi Julia, I am pretty sure it will work. I am so glad you found the blog and love the recipe idea! Let me know how the potatoes goes ! I always love to try new things 🙂 See you soon on the blog Julia, Carine.
