Keto Pie Crust | low carb, grain free, gluten free, sugar free, nut free

Three Ingredient Keto Pie Crust

It’s Pi Day, and since I love food (like the rest of the world), I’m also going to stretch this to mean “Pie Day.” In honor of this, I thought I’d trot out this recipe for a keto pie crust!

Anyway, I’ll admit it – I’ve never been able to make a good keto pie crust. I’ve tried (oh, how I’ve tried), but each and every time leaves something to be desired. Well, my friends, that has ended. I finally managed to get it together and actually create an edible keto pie crust. The secret? Butter and eggs. Yeah, I know. Years of watching Julia Child and Martha Stewart probably should have taught me this.

So, armed with my eggs, butter and coconut flour, I set off to make a keto pie crust. There was still trial and error (the first attempt involved salt, which has since been removed – you’re welcome), but we’ve finally arrived at a delicious crust recipe that was crazy easy to make and really, really tasty.

You can use this nut free beauty in both sweet and savory recipes. So, whether you’re in the mood for apple pie and pumpkin peanut butter pie, or you really have a hankering for spinach pie or buffalo cheddar pie… this is the recipe for you!

Keto Pie Crust | low carb, grain free, gluten free, sugar free, nut free

Some quick notes:

  • the butter substitute should be used directly out of the fridge – nice and chilly (it makes the dough easier to work with)
  • when smushing the pie crust into the pan, wetting your fingertips will help them to not stick to the dough
  • not all coconut flours are created equal – I really like how Nutiva bakes up (and it’s cheaper than most)
  • if the dough becomes too soft, chill it in the fridge for a few minutes
  • this is a pastry cutter (but a fork will work, too), and it makes everything so much easier. It’s kind of a unitasker, but if you make enough pies, it’s totally worth it.
  • this is how you use a pastry cutter – turn the volume down, there are children screaming in the background!
  • instead of the flax, you could use psyllium husk as a binder, and it will be much prettier. People have also reported good results with egg substitutes (though they’re a little higher in carbs), and also real eggs.

Okay, on to the keto pie crust recipe!

Three Ingredient Keto Pie Crust

This low carb pie crust is super simple, and bakes up flaky, yet strong enough to stand up to a solid filling!


  • 3/4 cup coconut flour
  • 8 tbsp (1/2 cup, 1 stick, 4 ounces) chilled, salted butter (or Earth Balance)
  • 2 flax eggs (or psyllium eggs, or eggs)


  1. In a mixing bowl, use a pastry cutter (or fork) to blend the coconut flour and butter until the texture is sandy, and there are no giant lumps of butter, or free floating dry bits of coconut flour.
  2. Add in two eggs, and mix until a thick dough forms and can be formed into a ball.
  3. If the dough is too dry and crumbly here, add in a tablespoon of cold water and keep gently kneading until the dough comes together.
  4. Press the dough into a 9" pie pan.
  5. The crust is ready to be used in a recipe!

    Can you recommend a low carb bread?

    • Liz December 12, 2015 at 5:35 pm

      Hi Janet – I have only tried the Julian Bakery breads. They’re okay, but pretty expensive!

      I’ve heard very good things about the breads from Thin Slim Foods, though I have yet to find them near me!!

      • Jan Monaco December 13, 2015 at 2:45 am

        Thanks so much for the reply. I have tried Samis Bakery multi grain bread – it is great but is $30.00 for three loaves on eBay. Comes from Florida. I really recommend it! I freeze it and it lasts me a long time.

        • Liz December 13, 2015 at 10:53 am

          Thank you for the recommendation! I’ll have to try that out. I’ve been trying to come up with my own recipe, but it is not easy!

          • Stephanie January 13, 2018 at 12:04 pm

            This is a late answer, but try looking for spelt flour bread recipes – I made gluten free bread with it that turned out well, and it’s much lower carb than wheat flour.

      • Jeane February 25, 2018 at 12:26 pm

        there is one on Pinterest, its 1 carb per slice ! try looking under Keto bread recipe ! Mine is in the oven now !

    • Cammi February 5, 2017 at 9:33 am

      While researching for Keto recipes, I had found this one for Keto Pancakes & Waffles. The reviews were really good for it, and one from someone caught my eye when she said she alters the recipe a little bit and uses for a bread substitute. I decided to give it a try, following the waffle recipe but leaving out the vanilla, cinnamon, maple extract, and almond milk, and using only half the sugar. I can now have sandwiches again!! I make a batch like this every Sunday and usually get between 7 and 8 waffles. I cut one waffle in half and use it as bread to make a sandwich (half fills me up about 90% of the time). Oops, one more thing. I also replace one of the tablespoons of coconut flour with a tablespoon of flax meal. I haven’t tried the recipe the normal way for waffles yet, but I’ll probably do so.

      • Liz February 5, 2017 at 11:12 am

        Thank you so much for sharing this!! It sounds amazing, and I’ve been looking for both a bread and a waffle substitute!!

        • Cammi February 7, 2017 at 1:46 am

          No problem! I hope you like it. I just got done having a sandwich, yum!! I really am going to need to try the recipe as written one day and make waffles, LOL.

    • Laura April 22, 2017 at 9:06 pm

      Thinslim bread. It’s only 1g net carbs per slice, and they have all kinds of low carb food. It’s only available through mailorder. I did find a frozen bread at Whole Foods, but it cost twice as much as Thinslim. They have a sampler pack for $19.99 that includes a loaf of bread, pasta, and several other items to try.

      • Liz April 22, 2017 at 9:08 pm

        Oooh, thank you! This sounds awesome! I’ll have to check it out 🙂

    • Christel September 23, 2017 at 10:12 am

      There is a great recipe for a Keto bread I have made. Texture is just like sliced bread. Comes from if you are up for baking your own.

    • Angie November 20, 2017 at 9:58 am

      Sara Lee has a 45 calorie bread that’s only 6 net carbs per slice….and it’s soft and delicious!

      • Liz November 20, 2017 at 3:02 pm

        Oh, awesome! Thanks so much for the recommendation!

    • Judy Hannah Reynolds March 11, 2018 at 2:56 pm

      These are amazing… I love them and make them often

  • Denise December 19, 2015 at 1:37 pm

    Can you replace the eggs with flax? Being Keto but allergic to nuts and eggs is not easy when it comes to baking!

    • Liz December 19, 2015 at 2:13 pm

      Oh, wow! I’m allergic to nuts, so I can’t imagine adding eggs to that! I thinks a flax egg should be fine 🙂

  • kitti April 7, 2016 at 4:49 pm

    How long do you cook it?

    • Liz April 7, 2016 at 4:53 pm

      Hi there, that depends on the recipe! You can either bake it by itself for 20 minutes, and then fill it, or just bake according to whatever time the recipe for a pie you’re using says. That’s usually between 30-45 minutes, depending on the filling. I hope this helped! 🙂

  • Lindsey April 26, 2016 at 11:29 am

    Tried this for a quiche. It’s a little fluffier than I thought it would be, but it was still delicious!!

    • Liz April 26, 2016 at 12:02 pm

      Thanks for commenting, Lindsey! I’m glad it was still delicious! I’ll make a note in the recipe that it’s fluffier than normal pie crust, so people know what to expect 🙂

  • Elizabeth Czilok June 10, 2016 at 9:25 am

    HI Liz!
    What type of pie do you use with this? Would this work as a cheesecake crust?


    • Liz June 10, 2016 at 9:32 am

      Hi Liz!! You could definitely use this for cheesecake!! I’ve made savory and sweet pies with this. 😀

    • Liz June 10, 2016 at 9:32 am

      And I’d love to know how your cheesecake turns out!!!

  • beth September 15, 2016 at 11:46 pm

    Will this hold up as a top crust, too?

    • Liz September 16, 2016 at 8:51 am

      Hi Beth – thanks for asking this question! I think if you chill the dough before rolling it out, and do so very carefully, it should hold up as a top crust. I’ve used it as a top crust on mini pies before and it was fine! It won’t be the prettiest, though!

      I’d love to know how it turns out if you try it!

  • Minerva November 17, 2016 at 9:08 pm

    Hello! What oven temp would you bake this at on its own?

    • Liz November 17, 2016 at 9:15 pm

      Hi Minerva! Thanks for commenting! This could be baked on its own at 350F as well, just for less time (try maybe 20 minutes at first and see). 🙂

  • Cynthia November 20, 2016 at 11:41 am

    Could you use this crust for pumpkin pie?

  • Diane Anderson December 17, 2016 at 3:02 am

    Hi! I can’t digest nut flours, so this looks perfect for me. However, I don’t live in the US so our butter doesn’t come in “sticks”, can you tell me how much a stick of butter weighs? I am really looking forward to trying this!

    • Liz December 18, 2016 at 10:28 am

      Hi there! Thanks for the comment 😀

      A “stick” of butter is 4 ounces/110 grams. I’ll fix the recipe to say that!

      • Diane December 18, 2016 at 10:49 am

        Thank you. I can’t wait to try this.

  • ann January 24, 2017 at 5:52 pm

    do you have to spread butter in the pan before you put the dough in it?

    • Liz January 25, 2017 at 10:27 am

      You do not! There’s enough fat in the dough that it should pop out without issue (I’ve never had a problem, at least!). If you’re worried, you could always add a teensy bit of butter or oil to the pan, but it’s definitely not necessary!

  • Theresa March 14, 2017 at 10:01 am

    Can I sub almond flour for coconut and would it be the same amount?

    • Liz March 14, 2017 at 12:25 pm

      You can certainly sub in almond flour, but it won’t be a 1:1 ratio. Coconut flour absorbs a loooot of moisture, and almond flour does not. So, you’ll at least have to double the amount of almond flour, and then keep adding in a little at a time until the consistency looks right!

      • Amy July 23, 2017 at 8:34 am

        Can I sub in chickpea flour?

        • Liz July 25, 2017 at 1:40 pm

          Oh, I haven’t tried this, but I don’t see why not. Chickpea flour is so versatile! Like with substituting with almond flour, the ratio won’t be 1:1, you’ll likely have to double the amount of flour and go from there.

          I’ll try to do a test on this soon, and post the results!

  • Tara June 28, 2017 at 10:35 am

    Do you bake this before filling?

    • Liz June 28, 2017 at 9:05 pm

      Hi Tara, thanks for the good question! You can either bake before adding a filling (like a custard), or bake it with the filling inside (I do this for quiches and such)!

  • Alice July 3, 2017 at 8:03 am

    I did this with a non-vegan version of your peanut butter pumpkin pie (I just doubled the filling and put in eggs instead of flax eggs), and it turned out incredibly well!

    I actually made the crust in the food processor (processing the flour and butter until broken into pea-size bits, adding the eggs and waiting for a ball to form). Really simple, easy, and quick! Thanks so much.

    • Liz July 7, 2017 at 11:23 am

      Hi Alice! Thanks so much for the comment. I’m so glad this turned out well! 😀

      And seriously, peanut butter and pumpkin is such a delicious and underrated combination.

  • Michele July 11, 2017 at 4:54 pm

    How is this pie crust vegan?

    • Liz July 11, 2017 at 4:57 pm

      Hi Michele! Good question. This recipe doesn’t actually say it’s vegan, as I posted it back when I still ate dairy, but there is a vegan modification mentioned in the notes! Basically, you can just replace the butter with coconut oil and a little salt.

      • Belinda November 19, 2017 at 11:49 pm

        Just what I was looking for! One daughter is vegan, one son us allergic to dairy, and one daughter is allergic to nuts, dairy, and wheat! Baking during the holidays is a challenge!

  • Chris August 6, 2017 at 12:14 pm

    Could you prebake the crust for a specific period of time, so that it’s more crust like?

    • Liz August 8, 2017 at 12:25 pm

      Hi Chris, you can definitely pre-cook this for about 20 minutes, so it’s a little crispier before adding in the filling! 🙂

  • Paula August 20, 2017 at 6:00 pm

    Hi Liz, I tried but the dough was too wet and I only puted one egg.

    • Liz September 10, 2017 at 6:52 am

      Hi Paula! This could be due to the brand of coconut flour used, or the size of the eggs. If you find the dough is too wet, you can always add in a little more coconut flour at a time until it reaches the correct texture!

  • Christine August 28, 2017 at 11:32 am

    Hi. Im from the UK and a bit co fused as to the measurements of ‘ 1 stick’ of butter. Can you pleasr share what that weighs in grams or ounces please! Tia…keep up the good work

    • Liz August 28, 2017 at 1:19 pm

      Hi! Sorry about this – I should just change this since a “stick” is really only understood if you are a) American and b) bake frequently. A stick is 8 tablespoons, or a quarter pound. However, 100g is pretty darned close to this!

      • diana October 2, 2017 at 9:30 am

        I was wondering abut the msmt of butter when i saw this recipe and searched these comments hoping to find a post like this… so this recipe should actually say 4 oz butter instead of 8 oz butter?

        • Liz October 2, 2017 at 2:08 pm

          Yes! So sorry! It should have read 8 tbsp (4 ounces). It’s fixed now – thank you so much for catching this!

  • Craftywitch August 30, 2017 at 4:52 pm

    Hi, I want to try this crust, but I usually use unsalted butter. Do you have any idea how much salt I should add if I don’t want to get salted butter just for one recipe?

    • Liz August 31, 2017 at 7:30 am

      Hi there, that’s a great question! You can usually add around a 1/4 tsp of salt to every stick of unsalted butter for similar results. 🙂

  • Jenn September 7, 2017 at 1:00 pm

    Can you combine all ingredients in a food processor? This is home I make regular pie crust.

    • Liz September 7, 2017 at 2:23 pm

      Good question, Jenn! You can definitely do this, though the texture is a bit different from a regular pie crust.

      • Jenn September 7, 2017 at 2:25 pm

        Thank you. I will give it a try. Just starting on this low carb journey.

        • Liz September 7, 2017 at 2:26 pm

          My pleasure! Good luck with your journey and let me know of you have any other questions!

  • Tamera September 9, 2017 at 7:39 pm

    How long and at what temp do you bake this (for a pie that’s just filled but not baked again). It’s in the oven right now so I’m guessing 335 for about 15-20! 🙂

    • Liz September 10, 2017 at 4:47 am

      Hi Tamera! I really depends on the filling, but if you’re just heating it and not cooking anything, then your temp and time looks right on!

      • Jessica November 21, 2017 at 8:07 am

        I did it at 425 for 10 mins! I had already popped it in the oven before I remembered the temp was high for a different recipe. It turned out really nice though. Just the right amount of light browning on the edges. And yes, it did hold up to the no-bake pumpkin cheesecake filling I dumped in it! It was really thick on the bottom though, so I might remove a bit of dough before putting it in the pie pan next time. Maybe use it for another crust for the extra filling I ended up with. And I think I’ll add a pinch of salt next time too.
        No complaints from the peanut gallery on this one though! Thanks!

        • Liz November 21, 2017 at 8:28 am

          Hi Jessica, thanks for the comment and feedback! It’s always nice to know different baking times and temps for things, especially around times when the oven is pretty full!! 🙂

  • Debi January 29, 2018 at 12:44 pm

    I know this maybe be a strange question, but how much almond flour would you use in place of coconut flour. I’m not a fan of coconut. I want to try this pie crust with sugar free cherry filling Thank you for sharing this recipe.

    • Liz January 31, 2018 at 2:23 pm

      Hi Debi, this isn’t a strange question at all! Unfortunately because almond flour and coconut flour have such different fat, protein and fiber profiles, it would be difficult to sub one for another. A sugar free cherry pie sounds delicious, though!

      I can give you my best guess, and that would be to use about a cup and a half of almond flour, and reduce the butter to 2 tbsp!

  • NANCY April 19, 2018 at 5:20 pm

    i just put a zucchini quiche with your crust in the oven. I’m doing a low carb diet.

    • Liz April 19, 2018 at 6:01 pm

      I hope you enjoy it, Nancy! Zucchini quiche sounds delicious!
