If you’ve been searching for the perfect way to enjoy rhubarb while doing keto, this low-carb strawberry rhubarb pie recipe should be at the top of your list.

Keto Strawberry Rhubarb Pie
I am so thrilled to finally be able to share a keto rhubarb and strawberry pie that has the potential to rival its high-carb counterpart.
If you are a fan of this seasonal combo, you are going to be delighted with this keto-friendly recipe.
Strawberries balance the tartness of rhubarb in this keto pie recipe perfectly. The best part is that it can be served at room temperature or cold for a delightful keto strawberry rhubarb dessert.
Are you wondering how many carbs are in a regular strawberry rhubarb pie? Well, a traditional one has, on average, 44 net carbs. That, my friend, means it’s a no-go on a keto diet.
However, the good news is that this low-carb rhubarb-strawberry pie has only 6.5 g net carbs per generous serving. This means that with a little macro planning, you can enjoy this rhubarb dessert while doing keto.
A 1/2 cup serving of rhubarb contains about 1.7 net grams of carbs, making it low-carb.
Low-Carb Strawberry Rhubarb Pie Recipe
As far as sourcing rhubarb for this pie, if you happen to live in a colder northern climate, you know it can be easily found in the local grocery store.
In fact, many people even grow rhubarb and usually find themselves with enough rhubarb to share. All I can say is that I hope you realize how blessed you are.
Here in South Florida, fresh rhubarb isn’t as readily available. Thankfully, it can be found frozen in some grocery stores. Thank you, Publix.
The good news is that this recipe has been adapted to use both fresh and frozen rhubarb, making it possible for more people to enjoy it.
How to Make Keto Strawberry Rhubarb Pie
If you are not familiar with cooking or baking rhubarb, it’s pretty straightforward. If using fresh rhubarb, be sure to remove the leaves since they are toxic.
After you wash the stalks, slice the rhubarb into 1/2-inch pieces. You can use frozen sliced strawberries and rhubarb, but you must thaw and remove excess moisture before adding it to the pie.
The tartness of the rhubarb and fresh strawberries comes together for keto pie you will be proud to share with your whole family!

How To Thicken The Filling
I used three cups of rhubarb and three cups of strawberries in this recipe to ensure it produced a nice tart pie, just as I liked it.
If you have ever made a strawberry rhubarb pie, you know that the filling can produce a lot of liquid when baked. It’s the only downside.
To avoid this, make sure that when combining the filling ingredients, you leave the extra liquid behind in the bowl.
Some pies use pectin, flour, or cornstarch to thicken their pie fillings, but none of those options are keto-friendly. I discovered that a tiny amount of psyllium husk powder does the same to ensure that the pie isn’t runny.
I use a small amount of psyllium husk powder over the strawberries and rhubarb pie filling to thicken the strawberry-rhubarb filling.
It’s important to note that the filling will thicken as it cools. This is why, straight out of the oven, the pie filling will still be a little loose and why it’s crucial to let the pie cool to room temperature before slicing.
Crust For Keto Pie
Until now, I have only been raving about the filling, and I haven’t even mentioned the fantastic crust that beautifully encloses this pie.
But trust me when I tell you that having a flaky, buttery keto pie crust is essential in this recipe. I used my pie crust recipe because it’s one I have perfected.
Not only does it have the texture we all expect, but this pie crust rolls beautifully and is not temperamental. An issue you find with most is the lack of gluten.

But this girl managed to crack the code for you with this crust.
The keto-friendly crust for this pie uses both coconut and almond flour.
But no need to worry because I have also tested the use of sunflower seed flour in place of almond flour, and it also works beautifully, creating a nut-free option if you need it.
Melted mozzarella cheese is also used in the pie dough. It’s the secret ingredient that makes this pastry roll out like a traditional crust recipe.
Once the dough is kneaded, it is divided in half, wrapped in parchment or cling wrap, and allowed to rest in the refrigerator for 30 minutes.
After the pastry is chilled, you can roll the dough easily between two parchment sheets of paper or wax paper. After it’s been rolled out, I place it back in the refrigerator for another 15 minutes.
Then it’s just a matter of adding the bottom crust to your pie dish, adding the filling on top, and then enclosing the pie with the top crust and baking.
Best Sugar Substitutes For Sugar-Free Strawberry Rhubarb Pie
As far as choosing your sweetener, my top choice is a monkfruit sweetener; it’s an erythritol blend. My personal favorite is Lakanto’s brand. But you can also use Swerve, an erythritol sugar substitute.
You could also use the stevia and erythritol-based brand Pyure for most of my baked goods. However, if using Pyure, you will want to use half the amount called for in this recipe since it’s a much sweeter choice.
Lastly, if you can’t easily find a more natural sweetener, you can also use Splenda for baking or a generic brand of the same. It will also work with great success.
I know not everyone would agree with me here, and I respect that, but in my book, it’s still better than regular sugar.

Keto Strawberry Rhubarb Pie (Gluten-Free)
Enjoy a keto strawberry rhubarb pie that is brimming with sweet strawberries and tart rhubarb and has the flakiest keto crust making it a swoon-worthy dessert.
Ingredients
Keto Pie Crust
- 1 cup of unsalted butter melted and cooled
- 2 large eggs, room temperature
- 1 cup of almond flour measured and sifted
- 1/2 cup of coconut flour
- 1/2 teaspoon of sea salt
- 2 cups of shredded mozzarella cheese, melted
Keto Strawberry Rhubarb Pie Filling
- 3 cups of sliced rhubarb (1/2 inch pieces)
- 3 cups of fresh strawberries sliced
- 1/2 cup of granulated sugar-substitute
- 1 tablespoon of unsalted butter cut into small pieces to dot the pie filling
- 1 1/2 teaspoons psyllium husk powder
- 1/4 teaspoon of sea salt
- 1/2 teaspoon of vanilla extract
Instructions
Keto Crust
- In a medium-sized bowl, combine the coconut flour and almond flour, and salt. Note if making the nut-free option use sunflower seed flour in place of almond flour and set it aside.
- Melt the unsalted butter and set aside.
- To the dry ingredients, add the melted butter and combine quickly.
- Next, add the two whole eggs and combine.
- Melt the mozzarella cheese in the microwave using 30-second intervals, mixing in between until fully melted but not crispy. This should take about three rounds in the microwave, depending on the power of your microwave.
- Once it comes out of the microwave, mix well until fully incorporated. You can also melt the mozzarella cheese in a double boiler.
- Add the melted mozzarella cheese to the mixture and knead the dough with your hands until all the cheese is blended well into the pie dough. I recommend you do so between two sheets of parchment paper so that the dough doesn't stick to your hands. Alternatively, you can use a stand-up mixer with a dough hook.
- Once the dough forms, divide the dough in half to make the top and bottom of the pie crust.
- Place the pastry dough in the refrigerator to rest the dough and allow the dough to chill. This will make it easier to work with and produce the flakiest crust.
- Roll out the dough between two sheets of parchment paper for both the top and bottom of the crust and place back into the refrigerator for another 15 minutes to cool again and make it easier to work with the dough
- Preheat oven to 350 degrees
Transfer one rolled crust to a 9-inch pie pan. Being careful to smooth any cracks. - Fill the pie with strawberry rhubarb filling and dot the pie with sliced butter.
- Add the top crust and make 5-6 slits to the top of the pie to let the steam vent as it cooks.
- Bake the pie until the topping is lightly brown, around 35-40 minutes.
- Store leftovers in the refrigerator for up to 5 days or freeze for up to 3 weeks.
Keto Strawberry Rhubarb Pie Filling
- In a large bowl, combine the sliced rhubarb, strawberries, sugar substitute, and vanilla extract. You can use frozen sliced strawberries and rhubarb, but you must allow them to thaw to remove the excess moisture before adding them to the pie.
- Next, sprinkle the salt and psyllium husk powder and combine well.
Notes
You can use frozen sliced strawberries and rhubarb but will need to thaw and remove excess moisture before adding to the pie.
