Ingredients
This Fresh Lemon Mousse requires a blend of rich ingredients that create its creamy texture and vibrant flavor.
For the Lemon Curd
- 1 stick unsalted butter, room temperature
- 1 cup granulated sugar
- 1 tablespoon fresh lemon zest
- Dash salt
- 4 large eggs
- 1/2 cup freshly squeezed lemon juice (about 4 lemons)
For the Lemon Filling
- 3 large whole eggs
- 3 large eggs, separated
- 1 cup plus 2 tablespoons granulated sugar
- 2 teaspoons lemon zest
- 1/2 cup freshly squeezed lemon juice, about 4 lemons
- Salt
For the Whipped Cream
- 1 cup heavy whipping cream
- 1/2 cup homemade lemon curd, room temperature (recipe above)
- 1 cup heavy whipping cream, cold
- 1/3 cup powdered sugar
- 1/2 teaspoon pure vanilla extract
How to Make Fresh Lemon Mousse
Step 1: Prepare the Lemons
Zest the lemons carefully, ensuring you only take off the yellow zest. Cut the lemons in half and juice them, reserving 1/2 cup of fresh lemon juice.
Step 2: Make the Lemon Curd
Cream the butter in a large mixing bowl using a stand mixer or hand mixer. Add sugar, salt, and zest; mix well. Crack eggs into another bowl, removing the chalaza from each yolk. Add eggs one at a time to the mixing bowl, mixing well after each addition. Incorporate lemon juice and salt before transferring to a medium saucepan. Cook on low heat while stirring constantly until thickened (about 8–10 minutes). Remove from heat.
Step 3: Cool and Store the Curd
Spoon the lemon curd into a bowl to cool at room temperature. Cover with plastic wrap directly on top to prevent skin formation. Once cooled, refrigerate or freeze leftovers.
Step 4: Create Lemon Filling
In a heatproof bowl, combine whole eggs, egg yolks, sugar, lemon zest, lemon juice, and salt. Whisk together. Set over simmering water on medium heat; whisk constantly until thickened like pudding (approximately 12 minutes). Remove from heat; cool for about 15 minutes before refrigerating covered in plastic wrap for 1-2 hours.
Step 5: Whip Egg Whites
Add about 2/3 of egg whites along with a pinch of salt into your stand mixer fitted with a whisk attachment or use a hand mixer. Beat until soft peaks form; add remaining sugar and beat until stiff peaks form. Gently fold egg whites into chilled lemon filling using a rubber spatula.
Step 6: Whip Cream
In the same mixing bowl (no need to wash), add heavy whipping cream. Start on medium-low speed until slightly thickened then increase to high speed until stiff peaks form. Carefully fold whipped cream into lemon mixture.
Step 7: Combine with Lemon Curd
Gently fold homemade lemon curd into the combined mixture until incorporated thoroughly. Transfer everything into a soufflé dish measuring 7 inches in diameter by 3 inches deep; chill in refrigerator for at least one hour.
Step 8: Prepare Topping
For serving topping – whip additional heavy whipping cream on medium-low speed until it starts thickening; add powdered sugar and vanilla extract then beat on high speed until stiff peaks form. Use either a decorating bag or spoon to dollop whipped cream over chilled mousse.
Step 9: Serve & Enjoy!
Optionally garnish with small quarter slices of lemon between dollops of whipped cream before serving cold. Refrigerate leftovers for up to five days or freeze for up to three months without garnishing until thawed.
Enjoy your delightful Fresh Lemon Mousse!
How to Serve Fresh Lemon Mousse
Fresh Lemon Mousse is a delightful dessert that can be served in various ways to enhance its zesty flavor and creamy texture. Here are some creative serving suggestions to impress your guests.
Individual Cups
- Serve the mousse in small glass cups for a beautiful presentation. This allows guests to see the layers and adds an elegant touch.
Garnished with Berries
- Top each serving with fresh berries, such as raspberries or blueberries. The tartness of the berries complements the mousse wonderfully.
Whipped Cream Topping
- Add a dollop of whipped cream on top for extra creaminess. You can pipe it on for a decorative look or simply spoon it over.
Lemon Slices
- Place thin slices of lemon around the mousse for added decoration. This brightens up the dish and gives an extra hint of citrus.
Mint Leaves
- Garnish with fresh mint leaves to add a pop of color and a refreshing aroma. It’s a simple way to elevate the dish visually.
Chocolate Shavings
- Sprinkle dark chocolate shavings on top for a rich contrast. The bitterness of chocolate beautifully balances the sweetness of the mousse.

How to Perfect Fresh Lemon Mousse
To achieve the best Fresh Lemon Mousse, consider these helpful tips that ensure a smooth and flavorful result every time.
- Use fresh ingredients: Always opt for fresh lemons and high-quality cream to enhance the flavor.
- Chill properly: Allowing the mousse to chill thoroughly helps develop its flavors and improves texture.
- Fold gently: When combining whipped cream and egg whites, fold gently to maintain airiness for that light, fluffy texture.
- Taste as you go: Adjust sugar or lemon juice according to your taste preferences for perfect balance.
- Avoid overcooking: When making lemon curd, cook just until thickened; overcooking can lead to a grainy texture.
- Store correctly: Keep any leftovers covered in the fridge for freshness, but avoid garnishing until ready to serve.
Best Side Dishes for Fresh Lemon Mousse
Fresh Lemon Mousse pairs beautifully with various side dishes that complement its bright flavor. Here are some delicious options:
- Shortbread Cookies: Their buttery crumb adds a delightful crunch alongside the creamy mousse.
- Fruit Salad: A mix of seasonal fruits provides freshness and balances out the richness of the mousse.
- Pavlova: This meringue-based dessert offers a crispy exterior and soft interior, perfect alongside lemon flavors.
- Scones: Lightly sweetened scones serve as a lovely contrast, especially when served warm with jam.
- Cheesecake Bites: Mini cheesecake bites offer a rich counterpart that pairs wonderfully with lemon’s tartness.
- Chocolate Fondue: Dip fruits into warm chocolate fondue for an indulgent experience that complements lemon’s brightness.
- Almond Cake: A moist almond cake provides nutty undertones that balance well with lemon’s acidity.
- Granola Parfaits: Layered granola with yogurt adds crunch and creaminess, creating a satisfying combination with mousse.
Common Mistakes to Avoid
Making Fresh Lemon Mousse can be simple, but there are common pitfalls that can ruin your dessert. Here are some mistakes to watch out for:
- Using stale ingredients: Always check your eggs and cream for freshness. Using old ingredients can affect the texture and flavor of your mousse.
- Overwhipping the cream: Whipping cream too much can turn it into butter. Stop when you see stiff peaks for a smooth finish.
- Skipping the cooling step: Allowing the lemon filling to cool properly is crucial. Skipping this can lead to a runny mousse.
- Not measuring accurately: Baking is precise. Use a scale or proper measuring cups to ensure you get the right amounts of each ingredient.
- Folding too harshly: When combining mixtures, fold gently with a spatula to maintain airiness in your mousse.
