High Protein Low Carb Strawberry Protein Mousse - Light, Creamy, and Satisfying
Ingredients
Method
- Bloom the gelatin. Sprinkle the gelatin over 3 tablespoons of cold water in a small bowl. Let it sit for 5 minutes. It will thicken and look spongy.
- Warm to dissolve. Microwave the bloomed gelatin for 10–15 seconds or warm gently on the stovetop until fully melted. Do not boil. Set aside to cool slightly while you prep the rest.
- Blend the base. In a blender or food processor, add strawberries, Greek yogurt, protein powder, sweetener, vanilla, and a pinch of salt. Blend until silky smooth. If the mixture seems too thick to blend well, add a splash of almond milk or water.
- Incorporate the gelatin. With the blender running on low, stream in the melted gelatin. Blend for 10–15 seconds to fully combine.
- Taste and adjust. Check sweetness and strawberry intensity. Add a touch more sweetener if your berries are very tart, or a few extra strawberry slices for a stronger flavor. Blend again briefly.
- Aerate for mousse texture. For extra fluff, transfer the mixture to a mixing bowl and whip with a hand mixer for 1–2 minutes on medium-high. This introduces air and gives you that mousse-like lift.
- Chill to set. Spoon into 2–3 serving cups. Refrigerate for at least 1–2 hours, or until lightly set and jiggly. The longer it chills, the firmer it gets.
- Garnish and serve. Top with a few strawberry slices or a dusting of sugar-free chocolate. Serve cold.
Why This Recipe Works
This mousse leans on strawberries for bright flavor and natural sweetness, then uses protein powder and Greek yogurt to deliver creaminess and structure without heavy cream or sugar. A touch of gelatin (or agar) helps it set into that airy, spoonable texture.
Because we blend and then chill, the mousse holds its shape but stays light. The result is a dessert-like snack that’s low carb, high protein, and ready in minutes.
Ingredients
- 1 cup fresh strawberries (hulled; frozen works too, thawed and drained)
- 3/4 cup plain 2% Greek yogurt (or skyr; choose unsweetened)
- 1 scoop vanilla whey or whey-casein blend (about 25–30 g; use a low-carb option)
- 2–3 tablespoons granulated zero-calorie sweetener (erythritol, allulose, or a blend; adjust to taste)
- 1 teaspoon unflavored gelatin (or 1/2 teaspoon agar-agar powder for a vegetarian option)
- 3 tablespoons cold water (for blooming the gelatin)
- 1/2 teaspoon vanilla extract
- Pinch of salt (heightens the strawberry flavor)
- Optional: 1/4 cup unsweetened almond milk or water to thin if needed
- Optional toppings: sliced strawberries, a few sugar-free chocolate shavings, or a mint leaf
Step-by-Step Instructions

- Incorporate the gelatin. With the blender running on low, stream in the melted gelatin. Blend for 10–15 seconds to fully combine.
- Taste and adjust. Check sweetness and strawberry intensity.
Add a touch more sweetener if your berries are very tart, or a few extra strawberry slices for a stronger flavor. Blend again briefly.
- Aerate for mousse texture. For extra fluff, transfer the mixture to a mixing bowl and whip with a hand mixer for 1–2 minutes on medium-high. This introduces air and gives you that mousse-like lift.
- Chill to set. Spoon into 2–3 serving cups.
Refrigerate for at least 1–2 hours, or until lightly set and jiggly. The longer it chills, the firmer it gets.
- Garnish and serve. Top with a few strawberry slices or a dusting of sugar-free chocolate. Serve cold.
Storage Instructions
- Refrigerate: Cover and store in the fridge for up to 3 days.
The texture may firm a bit over time.
- No freezing: Freezing can cause the mousse to separate and turn grainy once thawed.
- Keep covered: This prevents the top from drying out and keeps fridge odors away.
Why This is Good for You
High protein: The Greek yogurt and protein powder deliver 20–30 grams of protein per serving, depending on your scoop size and portion. That supports muscle recovery, satiety, and balanced blood sugar.
Low carb: Using a zero-calorie sweetener and fresh strawberries keeps sugars low. You get flavor and fiber without a sugar crash.
Nutrient dense: Strawberries bring vitamin C and antioxidants, while yogurt adds calcium and probiotics for gut health.
Light yet satisfying: The airy texture satisfies dessert cravings, and the protein keeps you full longer than a sugary mousse or pudding.
Common Mistakes to Avoid
- Skipping the bloom step: If you don’t bloom gelatin in cold water first, it can clump and won’t set evenly.
- Overheating gelatin: Boiling breaks it down and weakens the set.
Warm just until melted.
- Using too much liquid: Extra almond milk or watery berries can lead to a runny mousse. Drain thawed berries and add liquid slowly.
- Not chilling long enough: Give it time. At least 1 hour is needed; 2–3 hours is ideal for a firm, airy set.
- Choosing the wrong protein powder: Some powders are chalky or very thick.
A clean-tasting vanilla whey or a whey-casein blend works best for smooth texture.
Variations You Can Try
- Collagen boost: Swap half the whey for collagen peptides. It keeps carbs low and adds a silky finish.
- Dairy-free: Use a thick coconut yogurt and a plant-based protein powder. Agar-agar is your setting agent here.
- Chocolate-covered strawberry: Add 1 tablespoon unsweetened cocoa powder and a few sugar-free chocolate chips on top.
- Lemon-strawberry: Add 1–2 teaspoons lemon juice and a little zest for brightness.
Increase sweetener slightly to balance the tartness.
- Extra creamy: Fold in 2 tablespoons of light cream cheese after blending for more body and a cheesecake vibe.
- Berry mix: Replace half the strawberries with raspberries or blueberries for a mixed-berry mousse.
- Fiber boost: Blend in 1 teaspoon chia seeds. Let the mousse rest 10 minutes before chilling so they start to hydrate.
FAQ
Can I make this without gelatin?
Yes. Use agar-agar powder instead (about half the amount of gelatin) and simmer it in a few tablespoons of water for 1–2 minutes to activate.
You can also skip setting agents entirely and enjoy it as a thick protein pudding, though it won’t be as mousse-like.
Can I use frozen strawberries?
Absolutely. Thaw and drain them well to avoid excess water. You may need a touch more sweetener since frozen berries can be slightly less sweet.
What if I only have unflavored protein powder?
It will work.
Increase the vanilla extract to 3/4–1 teaspoon and add a bit more sweetener. A pinch of strawberry flavoring, if you have it, can help intensify the fruit notes.
Will a plant-based protein powder work?
Yes, but texture can be thicker or slightly gritty depending on the brand. Start with a smaller scoop, blend well, and add a splash of almond milk if needed.
Taste and adjust sweetness.
How much protein does each serving have?
It depends on your protein powder. With a typical 25–30 g scoop of whey and 3/4 cup Greek yogurt, each of two servings usually lands around 20–30 g protein. Split it into three servings for 15–20 g each.
Can I sweeten this with honey or maple syrup?
You can, but it will no longer be low carb.
If you prefer a natural low-calorie option, try stevia or a monk fruit blend instead.
How do I fix a mousse that didn’t set?
If it’s still tasty but soft, serve it as a thick smoothie bowl or parfait. Next time, ensure the gelatin was bloomed and fully dissolved, and chill it at least 2 hours. You can also re-bloom 1/2 teaspoon gelatin, melt, and whisk it into the mixture, then rechill.
Can I make it ahead for guests?
Yes.
Prepare it the day before and keep it covered in the fridge. Add fresh strawberry slices just before serving so they stay vibrant and juicy.
