Sugar-Free Cottage Cheese Lemon Mousse Recipe
Introduction
This Sugar-Free Cottage Cheese Lemon Mousse is a quick and refreshing dessert that’s light and tangy. Perfect for those looking for a healthier sweet option without sacrificing flavor, it takes just minutes to prepare and serves beautifully with fresh blueberries.

Ingredients
- 2 cups cottage cheese (full-fat gives a richer mouthfeel)
- 4 tablespoons powdered sweetener (allulose, monk fruit, or powdered erythritol)
- 2 tablespoons fresh lemon juice (more or less to taste)
- 2 teaspoons lemon zest, plus extra for garnish
- 1 teaspoon vanilla extract
- 2 tablespoons heavy cream (optional — use only if you want a looser texture)
- ½ cup fresh blueberries, for serving
Instructions
- Step 1: Combine the cottage cheese, powdered sweetener, lemon juice, lemon zest, and vanilla extract in a blender or food processor.
- Step 2: Puree the mixture on high for 30–60 seconds, stopping to scrape down the sides as needed, until completely smooth and airy.
- Step 3: If the mousse feels too dense, add 1 tablespoon of heavy cream and blend again. Repeat until you achieve a light, whipped texture, usually totaling 1–2 tablespoons of cream.
- Step 4: (Optional) Chill the mousse in the refrigerator for 15–20 minutes to set it firmer and enhance the lemon flavor.
- Step 5: Spoon the mousse into bowls or glasses, garnish with fresh blueberries and extra lemon zest, and serve immediately.
Tips & Variations
- For a dairy-free version, try substituting the cottage cheese and cream with blended silken tofu and coconut cream, adjusting sweetness as needed.
- Use a different citrus zest like lime or orange to vary the flavor profile.
- If you prefer a sweeter dessert, adjust the powdered sweetener to taste before blending.
Storage
Store any leftover mousse in an airtight container in the refrigerator for up to 2 days. Before serving, give it a gentle stir to restore creaminess. This mousse is best enjoyed fresh but can be chilled overnight for a firmer texture. Avoid freezing, as it may alter the texture.
How to Serve

Serve this delicious recipe with your favorite sides.
FAQs
Can I use regular sugar instead of powdered sweetener?
Yes, you can substitute with regular sugar or powdered sugar, but keep in mind it will increase the calorie and carbohydrate content, and you may need to adjust the amount to your taste.
What if I don’t have a blender or food processor?
You can achieve a similar texture by thoroughly mashing the cottage cheese and stirring in the lemon juice, zest, sweetener, and vanilla. The mousse may be slightly less smooth but will still be delicious.
