- Sugar-free: No added sugar — just clean, bright lemon flavor.
- Satisfying: The combination of protein and creaminess helps curb sweet cravings.
Key element — fresh lemon zest
Use both the zest and the juice. The zest carries the aromatic oils that give real lemon flavor, while the juice adds brightness and helps lighten the texture. Avoid bottled lemon juice if possible.
Ingredients
Mousse base
- 2 cups plain nonfat or low-fat Greek yogurt (thick style)
- 1 scoop (about 25–30g) vanilla or unflavored whey protein powder
- 2–3 Tbsp sugar-free sweetener (erythritol, allulose, or monk fruit), to taste
- Zest of 1 large lemon
- 2–3 Tbsp fresh lemon juice
- 1 tsp pure vanilla extract
- Pinch of salt
- 1–2 Tbsp milk of choice (only if needed for consistency)
Optional richer version
- 2 oz cream cheese, softened
- or 2–3 Tbsp heavy cream or coconut cream
To serve
- Extra lemon zest
- Optional: whipped cream (sugar-free), a few berries, or a thin lemon slice
Swaps
- Dairy-free: Use thick coconut yogurt and a plant-based protein powder.
- Extra tangy: Add more lemon zest or a few drops of lemon extract.
- Vanilla-forward: Use vanilla protein powder and reduce the lemon juice slightly.
- Berry swirl: Fold in a spoonful of pureed raspberries or blueberries (measure for carbs).
Instructions
| 1 | Mix the base. In a medium bowl combine the Greek yogurt, protein powder, sweetener, lemon zest, lemon juice, vanilla extract, and salt. If using cream cheese or heavy cream, add it now. |
| 2 | Blend until smooth. Mix with a spoon, whisk, or electric mixer until completely smooth and thick. Add a tiny splash of milk only if the mixture is too stiff. |
| 3 | Taste and adjust. Taste the mousse and add more sweetener or lemon zest if needed. The flavor will brighten slightly once cold. |
| 4 | Portion. Spoon or pipe into 4 small glasses or ramekins. For a lighter texture, you can fold in a little whipped cream before portioning. |
| 5 | Serve. Enjoy immediately or chill for 5–10 minutes if you prefer it colder. Top with extra lemon zest and any optional toppings just before serving. |
Pro tips
- Use thick Greek yogurt for the best texture — thinner yogurts make a looser mousse.
- Fresh lemon zest is essential for real lemon flavor; bottled juice alone will not be the same.
- An electric mixer or immersion blender gives the smoothest, airiest result.
- If the mousse is too soft, stir in a little more protein powder or chill it briefly.
- These keep well in the fridge for a couple of days — perfect for meal prep.
