My keto sour cream lemon pie is a lemon lover's dream. The tangy flavor of lemon is balanced beautifully with the addition of sour cream.
It's almost a no-bake keto lemon pie since the "graham" like crust is baked but the filling isn't.
The pie starts with a buttery, shortbread-like almond flour crust that is then topped with the low-carb sour cream lemon pie filling and then topped with fresh whipped cream for good measure.
This makes the perfect summer keto dessert. It's one you'll want to impress your family and friends with. Yup, it's a crowd-pleaser, you will be proud to share.
The best part, it has the right amount of sweetness!

Although this pie requires a little more time and effort, it is totally worth planning for, since it's a great option for a lemon lover doing keto craving a sour cream lemon pie recipe.
Don't be intimidated by the sound of making a homemade keto sour cream lemon pie, I am here to walk you through the steps to ensure you have the same great results!
You'll start by making a simple lemon curd over a double boiler by melting the butter and whisking in the sugar substitute, lemon juice, and lemon zest over medium heat. It's important to keep mixing until it's well combined.
Next, you'll proceed to whisk in the egg yolks one at a time and cook on low heat until the curd starts to thicken.
Then remove the lemon mixture off the stove and strain it into a small bowl. To the strained lemon mixture stir in the sour cream.

Allow to cool at room temperature and then store in the refrigerator while you make and bake the almond flour crust.
Once the pie crust is fully cooked and cooled add lemon sour cream filling to the prepared crust. Then it goes into the refrigerator for a minimum of an hour fully to set.
After the pie has spent some time chilling a quick cream topping is prepared and added to the top of the pie. All you'll do is beat the heavy cream until stiff peaks form.
Something you'll note is that I like adding a little cream cheese to my whipped cream so that it holds its peak. It's a little trick I learned years ago that adds lots of stability to homemade whipped topping.
Finally, the pie is garnished with lemon slices and lemon zest before serving.
Best Sugar Substitutes For Keto Sour Cream Lemon Pie
When it comes to choosing which sugar substitute to use for this sugar-free sour cream lemon pie, I have several for you to choose from.
My go-to choice is Lakanto Monk Fruit because the texture is spot-on since there is barely any aftertaste. It is a monk fruit and erythritol blend.
Lakanto Monk Fruit gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose. It's why it's a great all-natural sugar substitute and has zero calories and zero glycemic index.
I’m also partial to Swerve an erythritol blend. Unlike other natural sweeteners like stevia, it has no bitter aftertaste and measures just like sugar.
Swerve is the name brand of Erythritol it's unlike other sugar alcohols that have a 0 % impact on blood sugar.
You could also use the stevia and erythritol-based brand Pyure for this recipe. However, if you decide to use Pyure, you will want to use half the amount called for in this recipe since it's a much sweeter option.
Lastly, if you can easily find a more natural sugar substitute, you can also use Splenda with great success.
