Ingredients for Lemon Mousse:
- 1/2 cup fresh lemon juice (about 2 large lemons)
- Zest of 1 lemon
- 3/4 cup granulated sugar
- 1/2 cup heavy whipping cream
- 1/2 cup mascarpone cheese (or cream cheese for a lighter alternative)
- 2 large egg whites
- 1/2 teaspoon vanilla extract
- A pinch of salt

Step-by-Step Guide to Making Lemon Mousse:
1.Prepare the Ingredients:
Begin by zesting one lemon and squeezing the juice from two fresh lemons. Set both aside. In a separate bowl, whisk together the sugar and lemon zest.
2.Create the Lemon Custard:
In a medium saucepan, combine the lemon juice, sugar-lemon zest mixture, and a pinch of salt. Cook the mixture over medium heat while stirring constantly until the sugar dissolves. Once dissolved, remove from heat and allow it to cool for about 5 minutes.
3.Whip the Cream:
In a separate bowl, whisk the heavy whipping cream and vanilla extract until stiff peaks form. You can use a hand mixer or a stand mixer for this step.

4.Prepare the Egg Whites:
In another clean bowl, beat the egg whites until they form soft peaks. Slowly add in a tablespoon of sugar to stabilize the meringue.
5.Combine the Ingredients:
Gently fold the mascarpone (or cream cheese) into the lemon mixture until smooth. Then, carefully fold in the whipped cream to achieve a light, airy texture. Finally, add the egg whites and continue folding until the mousse is fully combined and creamy.
6.Chill and Serve:
Spoon the mousse into individual serving dishes or a large bowl. Refrigerate for at least 2 hours to allow the flavors to develop and the mousse to set.
7.Garnish and Enjoy:
Before serving, top with a sprig of mint, a thin lemon slice, or a sprinkle of lemon zest for an extra touch of elegance.

Why Lemon Mousse is Perfect for Any Occasion
Lemon mousse is not only an easy dessert to prepare but also an incredibly versatile one. Its refreshing citrus flavor makes it a perfect treat for summer events, but the creamy texture ensures it can be enjoyed year-round. Whether paired with a rich meal or served as a standalone dessert, lemon mousse offers a light alternative to heavier options.
Additionally, this recipe can be made ahead of time, giving you more freedom to focus on other aspects of your meal preparation. The delicate texture of the mousse also makes it a great dessert to serve in elegant glasses, adding a touch of sophistication to your table.
Expert Chef Tips for the Perfect Lemon Mousse:
- Use fresh ingredients: Fresh lemon juice and zest are crucial for achieving a vibrant flavor. Avoid bottled lemon juice for the best results.
- Whisk the egg whites to the right consistency: Soft peaks are essential for the mousse’s airy texture. Overwhipping can cause the mousse to become too stiff.
- Chill before serving: Allowing the mousse to set in the fridge helps the flavors meld together and gives it the perfect consistency.
