Keto Lemon Sour Cream Pie: A Creamy, Tangy Low-Carb Dessert

Why You’ll Love This Recipe

Keto Lemon Sour Cream Pie is a refreshing, creamy dessert that proves low-carb baking does not have to feel restrictive. With its bright lemon flavor and smooth, custard-like filling, this pie delivers the perfect balance of tangy and rich without the added sugar or carbs found in traditional versions. It is light enough to enjoy after a hearty meal yet indulgent enough to satisfy dessert cravings.

What makes this recipe especially appealing is its simplicity. The filling comes together quickly with minimal ingredients, and the sour cream adds a gentle tang that softens the sharpness of the lemon. I tested this pie with both fresh lemon juice and bottled, and fresh juice delivered a noticeably cleaner, brighter flavor. Whether you follow a keto lifestyle or simply want a lighter dessert option, this pie is elegant, reliable, and perfect for make-ahead occasions.

Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Almond flour forms the base of the crust, providing a nutty flavor and tender texture while keeping the pie low in carbohydrates.

Butter binds the crust and adds richness, helping it hold together once baked.

Low-carb sweetener sweetens both the crust and filling without adding sugar, keeping the pie keto-friendly.

Cream cheese creates a smooth, rich foundation for the filling and balances the acidity of the lemon.

Sour cream is the star ingredient, adding creaminess and a gentle tang that defines the pie’s flavor.

Eggs provide structure and allow the filling to set into a smooth, sliceable consistency.

Fresh lemon juice delivers bright citrus flavor and keeps the pie refreshing rather than heavy.

Lemon zest enhances the lemon aroma and adds depth without extra acidity.

Vanilla extract rounds out the flavors and softens the sharp citrus notes.

A pinch of salt balances sweetness and enhances the overall taste.

Directions

Preheat your oven to 175°C (350°F). Grease a pie dish lightly and set aside.

In a bowl, combine the almond flour, melted butter, and low-carb sweetener. Mix until the texture resembles damp sand. Press the mixture firmly into the bottom and sides of the pie dish. Bake for about 10 minutes, then allow the crust to cool slightly.

In a large mixing bowl, beat the cream cheese until smooth and lump-free. Add the sour cream and mix until fully combined.

Beat in the eggs one at a time, followed by the low-carb sweetener, lemon juice, lemon zest, vanilla extract, and salt. Mix until the filling is smooth and creamy, avoiding overmixing.

Pour the filling into the prepared crust and smooth the top. Bake for 35 to 40 minutes, or until the center is just set with a slight wobble.

Remove from the oven and allow the pie to cool completely. Refrigerate for at least two hours before slicing for best texture.

Variations and Customizations

This recipe is easy to adjust while staying keto-friendly. For a more intense lemon flavor, increase the lemon zest slightly. If you prefer a milder citrus note, reduce the lemon juice and add a touch more vanilla.
