This keto lemon mousse is not just a dessert, but also a subject of conversation: with its airy texture and bright citrus flavor, it adds a refreshing note to the menu.

Additional Tips for Perfect Keto Lemon Mousse

Use Room Temperature Eggs: Cold eggs will cause the curd to take much longer to set. Let them sit at room temperature before you start the recipe for a smoother result.

Avoid Over-Whipping: Be gentle when folding egg whites and whipped cream into the curd. Mixing too much may knock out the air, turning the mousse all thick rather than being light and fluffy.

Test the Lemon Curd for Thickness: You can know if your curd has set to the right consistency by dragging a spoon down the inside of the bowl. If it makes a trail that does not fill in quickly, it’s done!

Chill Your Equipment: If you want your whipped cream to work perfectly, chill your bowl, and also your whisk attachment for 10-15 minutes before whipping. This will make the cream hold up better.

Add some Gelatin for stability; In case you intend to shape your mousse into fancy shapes or even make mousse cakes, do add a small amount of dissolved gelatin for extra firmness.

Ideas for Decorating and Serving Lemon Mousse

Presentation can change everything! Here are some ways to serve your mousse:

Layered Mousse Cups: Alternate lemon mousse and sugar-free berry compote to make a pretty parfait.

Chocolate Drizzle: Top with a keto-friendly chocolate drizzle for a decadent chocolate and citrus pairing.

Mini Mousse Tartlets: Use the mousse to fill almond flour tart shells for a pretty dessert.

Candied Lemon Slices: Thin slices of lemon that have been cooked in a sugar-free syrup add a nice touch.

How to Make Low Carb Lemon Mousse

Step 1: Lemon Curd

In a large heat proof bowl, whisk together three whole eggs, three egg yolks (save the egg whites for later), 1/2 cup sweetener, zest of one lemon, juice of a lemon, and a pinch of salt. Place the bowl over the double boiler with gently boiling water, whisking continuously for 10-15 minutes until it has thickened into lemon curd. Allow it to cool down and cover with a plastic wrap to avoid skin formation. Refrigerate for 1-2 hours.

Step 2: Egg Whites

After the curd has cooled in the refrigerator for 1-2 hours, beat half of the set-aside egg whites with one tablespoon of sweetener and a pinch of salt with a stand up mixer or hand mixer to stiff peaks. Gently fold these stiff egg whites into the lemon curd, keeping the airy texture.

Step 3: Whipped Cream

In the same bowl with the egg whites, whip heavy whipping cream with vanilla extract and one tablespoon of sweetener to stiff peaks. Fold whipped cream gently into lemon and egg white mixture. And refrigerate covered for two hours before serving.

Serving Ideas

Serve this low-carb lemon mousse in small 4 oz tumblers, topped with a dollop of whipped cream, and garnished with a lemon wedge and mint leaf.

Tips for This Recipe

• Powdered Sweetener: If you have only granular sweetener, make your powdered sweetener by blending in a blender.
• Setting Time: Allow two hours of setting time for the lemon mousse before serving.
• Serving: This dessert is fabulous topped with raspberries, blackberries, or even crushed pecans.
• Storage: Keep in an airtight container in the refrigerator up to four days.

Variations of the Recipe

1. Lemon Cheesecake Mousse: To the beaten whipped cream, add 3 oz cream cheese. This will make for a very rich dessert.

2. Berry Lemon Mousse: For a more fruity twist, puree blueberries or strawberries in with the lemon curd.

3. Orange-Lemon Mousse: Use orange zest in place of the lemon zest for a citrus variation.

Frequently Asked Questions

Is this mousse diabetic-friendly?

Yes, this mousse uses sweeteners in place of the sugar; it’s a wonderful dessert for any diabetic. Although everybody reacts differently, careful monitoring of blood sugars may be necessary.

How many carbs per serving? Each serving has approximately  2g of net carbs.

Do I have to use fresh lemons for this recipe?

I would strongly suggest it. But if you must, you can use store-bought lemon juice. Note, though, that you should still use the zest of a fresh lemon.

Can I use coconut cream instead of heavy cream?

It can be used as a substitute for dairy-free preparations. However, it will leave a hint of coconut flavor on the mousse. Hence refrigerate it always before whisking.

Why isn’t my lemon curd thickening?

If your curd is not setting, turn the heat up a bit. Whisk constantly over simmering water for 10-15 minutes. Be sure your eggs are fully incorporated to help your curd set up well.

Can I make the perfect keto lemon mousse ahead of time?

Yes! This mousse can be prepared up to 1-2 days ahead. Just refrigerate in an airtight container and let chill until time to serve.
