This simple lemon-flavored treat strikes the perfect balance between light and creamy. The smooth cottage cheese base gets brightened up with fresh lemon zest and a touch of honey, creating something that’s not too sweet but totally satisfying.

It’s a crowd-pleasing sweet that’s on the lighter side, perfect for those times when you want something cool and refreshing.

What Kind of Cottage Cheese Should I Use?
For a smooth and creamy mousse, you’ll want to start with small or medium curd cottage cheese, as larger curds can leave your dessert too lumpy.
Regular 4% milkfat cottage cheese will give you the richest, creamiest result, though 2% will work if you’re watching your fat intake.
If you notice your cottage cheese is particularly watery, drain it in a fine-mesh strainer for about 30 minutes before starting your recipe.
Options for Substitutions
This light mousse recipe can be adapted with several easy swaps if needed:
- Cottage cheese: You can use ricotta cheese instead of cottage cheese – just make sure to blend it really well for a smooth texture. Greek yogurt is another option, though the final texture will be slightly different and you might need to add a bit more gelatin.
- Sugar-free maple syrup: Regular maple syrup works perfectly fine here. You can also use honey, agave nectar, or any liquid sweetener you prefer. If using stevia or another concentrated sweetener, add a bit of milk to maintain the right consistency.
- Gelatin powder: For a vegetarian version, use agar-agar powder instead – use the same amount but make sure to boil it with the water first until completely dissolved.
- Lemon zest and juice: While fresh lemon is best for this recipe, you can use lime or orange instead for a different citrus flavor. If using bottled lemon juice, reduce the amount by 1 teaspoon as it’s usually more concentrated.
- Vanilla essence: Since this is optional, you can skip it or replace it with almond extract or even a drop of coconut extract for a different flavor profile.
Watch Out for These Mistakes While Making
Getting the gelatin right is crucial – be sure to let it bloom in cold water for a full 5 minutes before heating it gently, and never let it boil as this will destroy its setting properties.
When incorporating the warm gelatin mixture into your cottage cheese base, do it gradually while continuously whisking to prevent gelatin strands from forming, and make sure your cottage cheese mixture isn’t too cold or the gelatin might set too quickly and create lumps.
For the best texture and flavor development, resist the urge to eat it right away – allow your mousse to chill in the refrigerator for at least 4 hours, though overnight is even better.
Storage Instructions
Chill: This lemon mousse needs a good 4 hours in the fridge to set properly, but for the best texture, I recommend letting it chill overnight. Once set, cover it with plastic wrap or a lid to prevent it from absorbing any fridge odors.
Keep Cold: Your mousse will stay fresh in the refrigerator for up to 3 days when stored in an airtight container. The lemon flavor actually gets better after a day, making this a perfect make-ahead dessert for your weekend gatherings!
Prep Ahead: If you’re planning a dinner party, you can make this mousse up to 2 days in advance. Just keep it covered in the fridge and add any fresh garnishes like lemon zest or mint leaves right before serving. The gelatin will help it maintain its shape beautifully.
Cottage Cheese Lemon Mousse FAQ
Why is my mousse not completely smooth?
Cottage cheese naturally has some texture to it, so your mousse won’t be as silky-smooth as traditional mousse made with heavy cream. If you want a smoother consistency, I recommend blending the cottage cheese in a food processor for 2-3 minutes before adding the other ingredients. This extra step helps break down those cottage cheese curds.
Do I need to bloom the gelatin first?
Yes, you absolutely need to bloom the gelatin first by sprinkling it over cold water and letting it sit for about 5 minutes. This step is crucial because it helps the gelatin dissolve properly and prevents any grainy texture in your final mousse. If you skip this step, you might end up with unpleasant gelatin lumps throughout your dessert.
Why isn’t my mousse setting properly?
The most common reason for mousse not setting is that the gelatin wasn’t properly heated after blooming. After the gelatin blooms, you need to heat it until it completely dissolves – either in the microwave for 10-15 seconds or over a double boiler. I make sure it’s fully liquid and clear before adding it to my mousse mixture.
