This vegan lemon mousse is light, fluffy, and bursting with fresh lemon flavor. It’s perfect for a refreshing dessert any time of the year!
Ingredients
7 tablespoons lemon juice (about 100 grams)
4 tablespoons sugar
1 teaspoon agar-agar (about 3 grams)
1/3 cup aquafaba (about 80 milliliters)
2 teaspoons lemon juice
Lemon essential oil (optional, for extra flavor)

Execution
Prepare Lemon Mixture: Place the 7 tablespoons of lemon juice, sugar, and agar-agar in a saucepan. Bring to a boil, stirring constantly, and cook for another 1-2 minutes until the mixture thickens.
Whip the Aquafaba: In a separate bowl, whip the aquafaba with the 2 teaspoons of lemon juice until stiff peaks form. This might take up to 10 minutes. When you turn the bowl upside down, the aquafaba should stay in place.
Combine Mixtures: Gradually fold the whipped aquafaba into the lemon mixture in three stages. Do this gently and slowly to maintain the fluffy texture. You can add a drop of lemon essential oil for extra flavor if desired.
Chill the Mousse: Pour the mousse into molds or serving glasses. Refrigerate for 2-3 hours or place in the freezer for 30 minutes to set. Garnish the mousse with lemon zest.
Additional tips
- Make sure your aquafaba is cold before whipping; it helps to form stiffer peaks.
- For a tangier mousse, add a bit more lemon juice or zest.
- Use fresh lemon juice for the best flavor.
How to Store:
- Keep any leftovers covered in the fridge for up to 3 days.
