Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

heavy cream
eggs
granulated keto sweetener
vanilla extract
salt
water
additional keto sweetener for caramel-style syrup

Directions

Preheat the oven to 325°F (165°C).

In a small saucepan, combine water and keto sweetener for the caramel-style syrup. Heat gently until the sweetener dissolves and slightly thickens. Pour a thin layer into the bottom of a flan mold or small ramekins and set aside.

In a mixing bowl, whisk together the eggs until smooth. Add the heavy cream, keto sweetener, vanilla extract, and salt, whisking until fully combined without incorporating too much air.

Carefully pour the custard mixture over the prepared caramel layer. Place the mold or ramekins into a baking dish and add hot water to create a water bath halfway up the sides.

Bake for 40 to 45 minutes, or until the center is just set with a slight jiggle. Remove from the oven and allow to cool completely, then refrigerate for at least 4 hours before serving.

Servings and timing

This recipe makes about 6 servings.
Preparation time is approximately 15 minutes, with a baking time of 40 to 45 minutes and at least 4 hours of chilling time. Total time is around 5 hours.

Variations

You can add a splash of espresso for a coffee-flavored flan or a pinch of cinnamon for warmth. Coconut cream can replace heavy cream for a dairy-free option. For extra richness, use egg yolks only instead of whole eggs.

Store Keto Flan covered in the refrigerator for up to 4 days. Serve chilled. Reheating is not recommended, as it can affect the custard’s texture.
