Over time, this classic dessert has undergone numerous transformations, with variations to suit different tastes and dietary preferences.

For the Meringue Topping:

Crust Preparation:

  1. Preheat your oven to 350°F (175°C).
  2. In a 9-inch springform pan lined with foil, combine almond flour, powdered sweetener, and grated lemon rind.
  3. In a separate bowl, whisk together melted butter, vanilla extract, and egg.
  4. Add the wet ingredients to the dry ingredients and blend well with a fork until a dough forms.
  5. Press the dough evenly into the bottom of the pan to form the crust.
  6. Bake for 8-10 minutes until lightly golden brown.
  7. Allow the crust to cool to room temperature before proceeding.

Cheesecake Base Preparation:

  1. In a medium-sized bowl or stand mixer, beat cream cheese, powdered sweetener, vanilla extract, and lemon juice until smooth and fluffy.
  2. Add eggs one at a time, ensuring each is fully incorporated before adding the next.
  3. Pour the cheesecake batter over the cooled crust in the springform pan.
  4. Bake in the preheated oven for 35-40 minutes or until the center is set.
  5. Leave the cheesecake in the oven to cool gradually.

Lemon Curd Topping Preparation:

  1. In a heat-safe bowl, whisk together eggs, egg yolks, lemon juice, powdered sweetener, and heavy cream.
  2. Cook the mixture over low heat, stirring constantly, until it thickens to coat the back of a spoon (approximately 7-10 minutes).
  3. Add butter to the mixture, one cube at a time, stirring until fully melted and incorporated.
  4. Transfer the lemon curd to a bowl and cover with plastic wrap, allowing the wrap to touch the surface of the curd.
  5. Chill the curd in the refrigerator until completely cooled and thickened.

Meringue Topping Preparation:

  1. In a clean, dry bowl, whip egg whites until light and fluffy.
  2. Gradually add allulose and vanilla extract while continuing to whip until stiff peaks form.
  3. Dollop the meringue over the chilled lemon curd topping or use a piping bag to create decorative swirls.
  4. If desired, use a kitchen torch to toast the meringue until lightly browned.

Serving and Storage Suggestions

  • Serve slices of the keto lemon cheesecake chilled, allowing the flavors to meld beautifully.
  • Store any leftovers in the refrigerator for up to four days, although the meringue topping may lose its texture over time.
