Sugar Free Strawberry Pie (Keto, Low Carb, Fresh Berries)

This sugar free strawberry pie is one of my favorite summer recipes, and I have been making it every strawberry season since 2019. With a buttery almond flour crust, a glossy filling made from fresh berries and just 4 grams of net carbs per slice, this low carb sugar free strawberry pie is the kind of keto dessert that nobody at the table will realize is better for you. The majority of carbs in this pie are from the almond flour and the fresh berries.

I originally developed this easy sugar free strawberry pie after a strawberry picking trip at Blooms and Berries here in Cincinnati. Growing up on a farm in Louisiana, fresh strawberry pie was one of my mom's go to desserts, and I wanted to recreate that same flavor without all the refined sugar. After years of following a ketogenic diet, I knew it was possible to make a version that tastes every bit as good as the original.

Whether you are bringing dessert to a Fourth of July cookout, a summer baby shower, or you just want something sweet after dinner, this keto strawberry pie delivers. The filling comes together on the stovetop in about 10 minutes, the almond flour crust bakes in 15, and once it chills in the fridge, you have a gorgeous pie that slices beautifully. Add some blueberries and whipped cream on top and you have the perfect red, white, and blue patriotic dessert.

Why This Sugar Free Strawberry Pie Works

Most sugar free pie recipes rely on boxed gelatin mixes that contain artificial colors and questionable sweeteners. This recipe takes a different approach. The filling uses real strawberries, water, and xanthan gum as the thickener instead of cornstarch or gelatin packets. This keeps the carb count lower than recipes that use cornstarch while still giving you a filling that holds together when you slice.

The almond flour crust is another win. Instead of a store bought graham cracker crust (which is loaded with sugar and wheat flour), you get a rich, buttery, slightly sweet crust that complements the berries perfectly. It takes a few extra minutes, but it is absolutely worth it for both the flavor and the macros.

Here is what sets this keto fresh strawberry pie apart from others:

• Fresh berries, not frozen – The filling uses 5.5 cups of sliced fresh strawberries for the best texture and flavor. Fresh berries hold their shape better and do not release as much water as frozen, which prevents a soggy crust.
• Xanthan gum thickener – Instead of cornstarch (which adds carbs) or sugar free jello packets (which add artificial ingredients), xanthan gum creates a smooth, glossy filling with virtually zero carb impact.
• Erythritol sweetener – Swerve or any erythritol blend adds sweetness without spiking blood sugar. Erythritol has zero glycemic impact and does not contribute to net carbs.
• Grain free almond flour crust – High in protein and healthy fats, low in carbs, and it tastes like a real pie crust.

Key Ingredients and Keto Substitutions

You can find all of these ingredients at most grocery stores or order them online. Here is a closer look at the key players and what you can swap if needed.

Almond flour is the base of the crust. Use a finely ground blanched almond flour (not almond meal) for the best texture. If you have a nut allergy, you could try sunflower seed flour, but the flavor will be slightly different.

Xanthan gum serves double duty in this recipe. A small amount goes into the crust to help it hold together (almond flour crusts are more fragile than wheat), and it is also the thickener for the strawberry filling. A little goes a long way, so measure carefully.

Swerve sweetener (erythritol) is my go to for this recipe. You can substitute monk fruit sweetener or allulose if you prefer. Note that allulose will make the filling slightly softer since it does not crystallize the same way erythritol does. If you use a concentrated sweetener like pure stevia, you will need to adjust the amount significantly since Swerve measures cup for cup like sugar.

Fresh strawberries are essential here. I strongly recommend using fresh, in season berries rather than frozen. Frozen strawberries release too much liquid as they thaw, which can make the filling watery and the crust soggy. If strawberries are not in season where you are, this recipe is best saved for when they are. Check out the keto food list for other fruits that work well on a low carb diet.

Instructions

Keto Pie Crust Instructions

• Add all dry ingredients into food processor and pulse to blend.
• Add the rest of the ingredients except butter and pulse until crumbs begin to form.
• Add butter and pulse until large crumbs begin to form and dough just starts to come together. Do not overwork the dough.
• Form dough into a ball and place in the freezer for at least 30 minutes.
• Preheat convection oven to 325 degrees or 350 degrees for conventional.
• Roll out dough between parchment paper, lumps of butter will still be visible. Keto pie crust is more fragile than traditional crust, so be sure to work quickly.
• Place dough into a 9 inch pie plate. Flute edges if desired or use fork to make indentions of the edge of the crust.
• Poke holes in the crust.
• Bake crust for 15 minutes or until edges are golden brown.
• Allow crust to cool for about 15 minutes.

Strawberry Pie Filling Instructions

• Slice strawberries lengthwise.
• Boil 3/4 cup water in a saucepan large enough to hold 4 cups of strawberries. There will be 1 1/2 cups of strawberries left out of this mixture for topping the pie.
• Remove 1/4 cup of hot water from the pan and whisk in 2 teaspoons of xanthan gum until dissolved.
• Add strawberries, xanthan gum mixture and swerve back to the saucepan.
• Stir mixture constantly over medium heat until combined and add the remaining 1/2 cup of water.
• Continue stirring until liquid is reduced and mixture is thickened, about 7-10 minutes.
• Remove from heat and allow mixture to cool.

Assembling the Strawberry Pie

• Once the crust and strawberry mixture have come to room temperature, add the filling to the crust and smooth.
• Arrange the remaining fresh strawberries on the top of the pie to create a design.
• Chill pie in the refrigerator for about an hour or until filling is set.
• Serve with whipped cream and garnish with fresh mint, if desired.

Tips for the Best Sugar Free Strawberry Pie

After making this keto strawberry pie dozens of times over the years, here are the things that make the biggest difference in how it turns out.

Freeze the dough before rolling. Almond flour dough is sticky and fragile. Chilling it in the freezer for at least 30 minutes makes it much easier to roll out and transfer to the pie plate. Roll it between two sheets of parchment paper and work quickly, because it softens fast at room temperature.

Do not skip the fork holes in the crust. Poking holes prevents the crust from puffing up during baking. You can also use pie weights or dried beans on parchment for an even flatter result.

Let both components cool completely before assembling. If you pour warm filling into a warm crust, the crust will absorb too much moisture and lose its texture. Patience pays off here.

Stir the filling constantly while cooking. Xanthan gum can clump if you do not keep it moving. Whisk it into the hot water separately before adding it to the strawberry mixture, and stir continuously over medium heat until the filling thickens, about 7 to 10 minutes.

Chill for at least one hour before serving. The filling needs time in the refrigerator to fully set. For the cleanest slices, chill for two hours or even overnight.

Sugar Free Strawberry Pie Variations

Once you have the basic recipe down, there are plenty of ways to change it up. Here are some of my favorite variations.

Sugar Free Strawberry Cream Pie: After the filling has set, top the pie with a layer of keto whipped cream. Whip 1 cup of heavy cream with 2 tablespoons of Swerve confectioners and a splash of vanilla until stiff peaks form. Spread over the top and chill for another 30 minutes. This version is richer and more indulgent.

Keto Strawberry Jello Pie: If you prefer a firmer, more traditional jello-style filling, you can dissolve one packet of sugar free strawberry gelatin into 1 cup of boiling water, let it cool slightly, and pour it over the fresh sliced strawberries in the crust. Chill until set, about 4 hours. This version has a slightly different texture but captures that classic Shoney's strawberry pie flavor that many people remember.

No Bake Strawberry Mousse Pie: For a completely no bake option, blend 2 cups of fresh strawberries with 8 ounces of softened cream cheese, 1/2 cup of Swerve, and 1 cup of whipped heavy cream. Pour into a pre-baked and cooled almond flour crust and refrigerate for at least 3 hours. The mousse version is lighter and almost cheesecake-like.

Sugar Free Strawberry Rhubarb Pie: Replace about 1.5 cups of the strawberries with chopped rhubarb. Since rhubarb is quite tart, you may want to increase the sweetener slightly. Cook the rhubarb pieces in the filling mixture a few minutes longer than you would for strawberries alone so they soften properly.

Crustless Sugar Free Strawberry Pie: If you want to save carbs and time, skip the crust entirely. Pour the thickened strawberry filling into a greased pie dish and chill until set. You lose the buttery crust but drop the net carbs per serving even further.

Can You Eat Fruit on Keto?

One of the most common questions from people starting a ketogenic diet is whether fruit is allowed. The short answer is that most fruits are too high in sugar for strict keto, but berries are the notable exception.

Strawberries are one of the lowest sugar fruits you can eat. A half cup of sliced strawberries has about 4.7 grams of net carbs and 4.1 grams of sugar. For comparison, a medium apple has around 20 grams of sugar. When you spread those strawberry carbs across 10 slices of pie, the per serving impact is very manageable.

The type of sugar in fruit is fructose, which is processed differently than glucose. Fructose must be converted to glucose in the liver before the body can use it for energy. When you eat more fructose than the liver can handle at once, the excess can contribute to elevated triglycerides and potentially fatty liver over time. Research also suggests that fructose may not suppress appetite as effectively as glucose and could contribute to leptin resistance, which affects hunger signaling.

That said, the amount of fructose in a slice of this sugar free strawberry pie is quite small, especially compared to a conventional pie loaded with refined sugar. If you are following keto 90 to 99 percent of the time and are generally healthy, an occasional serving of berries or a slice of keto strawberry pie is unlikely to derail your progress. If you are dealing with specific health concerns like fatty liver, you may want to be more cautious with fructose. The ketogenic diet has shown promise for reversing fatty liver, and keeping fructose intake low supports that process.

Using a blood glucose or ketone monitor can help you understand how your body responds to berries specifically. I use one regularly and find that a serving of strawberries has minimal impact on my ketone levels. Everyone is different though, so testing is the best way to know for sure.

Keto Strawberry Pie Nutrition Breakdown

Here is what you are looking at per slice when this sugar free strawberry pie is cut into 10 servings from a 9 inch pie:

• Calories: 192
• Total Carbohydrates: 12g
• Fiber: 5g
• Net Carbs: 7g
• Protein: 6g
• Fat: 15g
• Sugar: 5g (naturally occurring from strawberries)

The erythritol/Swerve is not included in the net carb count since sugar alcohols are not absorbed by the body. The 7 grams of net carbs comes almost entirely from the strawberries and the almond flour in the crust. For context, a single slice of traditional strawberry pie from a restaurant typically has 40 to 60 grams of sugar and 50 or more total carbs.

If you are tracking macros closely, you could bring the net carbs down a bit by making 12 slices instead of 10, or by trying the crustless version mentioned in the variations section above.

Storage and Make Ahead Tips

This pie stores well in the refrigerator for 3 to 4 days covered with plastic wrap or in an airtight container. The filling will stay set and the crust holds up nicely, though it does soften slightly after the first day.

For make ahead prep, you can bake the crust up to two days in advance and store it at room temperature. Make the filling the day you plan to serve and assemble at least one to two hours before serving to give it time to chill and set.

I do not recommend freezing this pie. The fresh strawberry filling does not freeze and thaw well. The texture changes significantly and the filling can become watery when it thaws. If you want to prep ahead for a party, making it the night before and letting it set overnight in the fridge actually gives you the best results.
