Key Ingredients:

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Greek Yogurt or Cottage Cheese

This forms the rich, high-protein base of our mousse. Additionally, it delivers an amazingly smooth, tangy texture that mimics heavy cream naturally.

Vanilla Protein Powder

It adds sweetness while dramatically boosting the protein content. Consequently, choosing a high-quality whey or plant powder ensures a silky finish.

Fresh Lemon Juice and Zest

These provide vibrant, bold citrus flavor throughout the dish. Therefore, freshly squeezed juice works best to achieve that signature zesty bite.

Sugar-Free Sweetener

It balances the sharp citrus tartness without adding unwanted carbs. However, powdered keto sweeteners blend smoothest into the creamy mixture.

Fresh Blueberries

These add a vibrant pop of color and juicy fruit flavor on top. Furthermore, they keep net carbs low while providing natural sweetness.

How to Make Protein Lemon Mousse

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

1. Add the Greek yogurt, vanilla protein powder, fresh lemon juice, lemon zest, and sweetener into a high-speed blender or mixing bowl.
2. Blend or whip vigorously on high speed for approximately 2 to 3 minutes until the mixture turns completely smooth, airy, and creamy.
3. Spoon the fluffy lemon mousse evenly into two individual serving ramekins or small glasses.
4. Chill the ramekins in the refrigerator at 38°F (3°C) for at least 30 minutes to allow the mousse to set firmly.
5. Top each chilled serving with fresh blueberries and extra lemon zest right before serving.

Pro Tip: Use powdered sweetener instead of granulated options to ensure your mousse achieves an impossibly smooth, velvety mouthfeel without any grit.

Common Mistakes to Avoid:

• Using bottled lemon juice which creates a harsh, artificial taste instead of fresh, bright flavor.
• Skipping the lemon zest because the essential oils in the peel provide most of the citrus aroma.
• Over-blending liquid bases which can make the mousse too runny instead of thick and fluffy.
• Using gritty protein powder that ruins the smooth, luxurious texture of the final dessert.

Required Equipment:

• High-Speed Blender or Hand Mixer — creates a light, silky-smooth mousse texture effortlessly in minutes.
• Microplane Zester — yields fine, fragrant lemon zest without grating the bitter white pith.
• Glass Ramekins — offers ideal portion control and keeps the dessert chilled perfectly.

Caleb’s Recipe Tips

• Whip the protein base extra long to incorporate air for a lighter texture.
• Add a splash of unsweetened almond milk if your protein powder makes the mixture overly thick.
• Chill serving dishes beforehand so your mousse stays cool and firm while serving.
• Fold in whole blueberries directly into the mousse for extra fruit bursts throughout.

Storage Instructions

• Refrigerator storage: Store covered tightly with plastic wrap in the fridge.
• Freezer storage: Freeze for up to 1 month; thaw slightly before eating for an ice-cream-like treat.
• Containers: Use airtight glass ramekins or small meal prep containers.
• Shelf life: Keeps remarkably fresh for 3 to 4 days in the refrigerator.
• Reheating tips: Do not heat; serve directly chilled from the refrigerator.
