I love making this keto lemon mascarpone mousse when I want something light, creamy, and refreshing without breaking my low-carb routine. It has a silky texture with a bright lemon flavor that feels indulgent but stays perfectly keto-friendly.
Why You’ll Love This Recipe
I enjoy how quick and simple this mousse is to prepare, yet it tastes like a fancy dessert. I only need a few ingredients, and the balance between the tangy lemon and rich mascarpone always turns out perfect. I also like that it’s naturally low in carbs and sugar, making it a great option when I want something sweet without guilt.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
1 cup mascarpone cheese
1/2 cup heavy whipping cream
1/3 cup powdered erythritol or preferred keto sweetener
2 tablespoons fresh lemon juice
1 teaspoon lemon zest
1 teaspoon vanilla extract
Directions
I start by placing the mascarpone cheese in a mixing bowl and gently softening it with a spatula. In another bowl, I whip the heavy cream until soft peaks form.
Then I add the powdered sweetener, lemon juice, lemon zest, and vanilla extract to the mascarpone and mix until smooth and creamy. I carefully fold the whipped cream into the mascarpone mixture, making sure to keep the texture light and airy.
Once everything is well combined, I spoon the mousse into serving glasses and refrigerate it for at least one hour before serving.
Servings and timing
I usually get about 4 servings from this recipe.
Preparation time takes around 10 minutes, and I chill it for about 1 hour before serving.
Variations
I sometimes switch things up by adding a few fresh berries on top for extra flavor. When I want a stronger citrus taste, I mix in a bit of lime juice along with the lemon. For a richer version, I occasionally add a little cream cheese to deepen the texture.
storage/reheating
I store any leftovers in an airtight container in the refrigerator for up to 3 days. I don’t reheat this mousse since I prefer it chilled. If it firms up too much, I just let it sit at room temperature for a few minutes before eating.
