This Diabetic-Friendly Lemon Mousse is bright, creamy, silky, and wonderfully refreshing. Fresh lemon juice and zest bring a vibrant citrus flavor to a smooth combination of Greek yogurt and cream cheese, while a zero-sugar sweetener adds just enough sweetness without traditional sugar.

Light and elegant but incredibly easy to prepare, this low-sugar lemon dessert is perfect for after-dinner cravings, summer gatherings, or whenever you want something cool and refreshing. The Greek yogurt also adds protein, making this a more protein-friendly choice than many traditional mousse recipes.

Can This Lemon Mousse Support Weight Loss Goals?

This mousse can fit into a balanced, calorie-conscious eating pattern when enjoyed in a moderate portion. Greek yogurt provides protein, while using reduced-fat cream cheese and a moderate amount of whipped cream helps control calories. Choosing a zero-sugar sweetener instead of regular sugar also keeps added sugar low.

It is still a dessert, so portion size and the overall meal pattern matter when working toward personal weight-management goals.

Does This Recipe Fit a High-Protein Lifestyle?

This lemon mousse is protein-friendly rather than exceptionally high-protein. Greek yogurt supplies most of the protein, while cream cheese contributes a smaller amount. It contains relatively low net carbs compared with many traditional sugar-sweetened desserts, although the exact amount depends on the dairy products and sweetener used.

Common Mistakes to Avoid

Using thin yogurt: Watery yogurt can make the mousse loose. Use thick, strained Greek yogurt.
Adding too much lemon juice: Excess liquid can thin the mousse and make it overly tart. Measure carefully.
Overmixing whipped cream: Whipping beyond stiff peaks can make the cream grainy or buttery.
Adding warm cream cheese: Very soft or warm cream cheese can create a loose filling. It should be softened but still cool.
Skipping the chilling time: The mousse needs refrigeration to develop its best texture.

Fine grater — produces fragrant lemon zest without the bitter white pith.
Citrus juicer — extracts fresh lemon juice efficiently.

📝 Ingredients

Lemon Mousse

1 cup (240 g) plain, unsweetened Greek yogurt
4 oz (113 g) reduced-fat cream cheese, softened
½ cup (120 ml) heavy whipping cream
3 tablespoons powdered monk-fruit/erythritol sweetener, or adjust to taste
2 tablespoons fresh lemon juice
1 tablespoon finely grated lemon zest
1 teaspoon vanilla extract
⅛ teaspoon salt

Optional Garnish

Thin lemon slices
A little finely grated lemon zest
Fresh mint leaves
A few fresh berries

Ingredient Notes

Use thick, plain Greek yogurt for the best mousse consistency.

Fresh lemon juice and zest provide much better flavor than bottled lemon juice.

Choose a powdered zero-sugar sweetener so it dissolves smoothly into the mousse. Sweetener blends vary in sweetness, so adjust according to the product you use.

Directions

Prepare the lemon.
Wash and dry the lemon thoroughly. Finely grate the yellow outer peel, avoiding the white pith because it can taste bitter.
Juice the lemon.
Squeeze enough fresh lemon juice to measure 2 tablespoons. Strain out any seeds.
Prepare the cream cheese.
Place softened cream cheese in a large mixing bowl and beat with an electric mixer over medium speed for 1–2 minutes, until smooth and creamy.
Add the Greek yogurt.
Add the Greek yogurt and beat for another 30–60 seconds until fully combined.
Add lemon and sweetener.
Mix in powdered monk-fruit/erythritol, lemon juice, lemon zest, vanilla, and salt.
Taste the mixture.
Taste before adding the whipped cream. Add a little more sweetener if needed, remembering that chilling can slightly change the perceived sweetness.
Whip the cream.
In a separate cold bowl, whip the heavy cream on medium-high speed for 2–3 minutes until soft-to-stiff peaks form. The cream should hold its shape without looking grainy.
Fold gently.
Add approximately one-third of the whipped cream to the lemon mixture and gently fold it in with a rubber spatula.
Add the remaining cream.
Fold in the remaining whipped cream in two additions. Use slow, sweeping motions to preserve the airy texture.
Check the texture.
The finished mousse should be smooth, fluffy, and thick enough to hold soft peaks.
Portion the mousse.
Spoon or pipe the mixture evenly into six small dessert glasses.
Chill.
Cover and refrigerate for at least 2 hours. For the best texture and flavor, chill for up to 4 hours.
Garnish.
Add a little lemon zest, a thin lemon slice, mint, or a few berries immediately before serving.
Serve cold.
Serve directly from the refrigerator for the creamiest texture.

High-Protein Cooking Tip

For a more protein-friendly mousse, use a high-protein strained Greek yogurt. You can also reduce the amount of whipped cream slightly and increase the Greek yogurt, although the mousse will become somewhat denser.
