Ingredients
- For the Keto-Friendly Crust:
- 1 ½ cups almond flour, finely ground
- ¼ cup coconut flour
- ⅓ cup powdered erythritol
- ½ tsp xanthan gum
- ¼ tsp salt
- 1 large egg, lightly beaten
- 6 tbsp unsalted butter, cold and cubed
- for the Zesty Lemon Custard Filling:
- 4 large eggs
- ¾ cup powdered erythritol
- ⅔ cup fresh lemon juice (about 3-4 lemons)
- 1 tbsp lemon zest, finely grated
- ½ cup heavy cream
- 2 tbsp unsalted butter, melted
- 1 tsp vanilla extract
instructions
- Prepare the Keto Crust: Combine almond flour, coconut flour, powdered erythritol, xanthan gum, and salt in a large mixing bowl. Add the cold cubed butter and use a pastry cutter or your fingertips to blend until the mixture resembles coarse crumbs.
- Add the beaten egg and stir gently until the dough begins to clump together. If too dry, add 1 tbsp cold water at a time. Form into a disc, wrap in plastic, and refrigerate for 30 minutes to firm up.
- Roll out and Bake the Crust: Preheat your oven to 350°F (175°C). Roll the dough between two sheets of parchment paper into a 9-inch circle and gently press into a tart pan with a removable base.Prick the base with a fork to prevent bubbling.
- Line the crust with parchment paper and fill with pie weights or dried beans. Bake blind for 15 minutes. Remove weights and parchment, then bake for an additional 8-10 minutes until the edges are golden brown.Let cool.
- Make the Lemon Custard Filling: in a medium bowl, whisk together eggs and powdered erythritol until pale and slightly thickened. Incorporate fresh lemon juice, lemon zest, heavy cream, melted butter, and vanilla extract until smooth and glossy.
- Bake the Tart: Pour the lemon custard filling into the cooled crust.Bake at 325°F (160°C) for 20-25 minutes until the filling is just set with a slight wobble in the center. Avoid overbaking to keep that luscious creaminess.
- Remove the tart from the oven and cool to room temperature, then refrigerate for at least 2 hours to fully set and intensify the flavors.
- Final Touches: Before serving, garnish with thin lemon slices, a light dusting of powdered erythritol, or fresh mint leaves for vibrant contrast.
Tips for Success with Your Zesty Keto Lemon Tart
- Ingredient Quality Matters: Use fresh lemons for the juiciest, most aromatic flavor. Bottled lemon juice can lack brightness and freshness.
- prevent a Soggy Bottom: Blind bake the crust thoroughly and cool completely before adding custard to maintain a crisp base that holds its shape.
- Sweetener Alternatives: You can substitute erythritol with allulose or monk fruit sweetener for diffrent sweetness profiles, keeping carbs low.
- Texture Tips: If your custard cracks or curdles, it’s often due to overbaking or too high heat. Bake low and slow to maintain the perfect creamy texture.
- Make-Ahead Friendly: This keto lemon tart tastes even better after a full day in the fridge, making it ideal for parties or special dinners.
- Storage: Cover tightly and refrigerate for up to 4 days. Freeze individual slices wrapped in aluminum foil for up to 1 month.
Serving suggestions
