Ingredients You Need

Strawberry Sugar-Free Jelly (17g sachet) This is the key to both flavor and structure. It provides sweetness and helps the mousse set. Make sure it is fully sugar-free. Regular jelly will increase carbs significantly and alter the consistency.

Boiling Water (250ml) Used to dissolve the jelly completely. Do not skip fully dissolving the granules or you will get grainy texture.

0% Greek Yoghurt (290g) This adds creaminess and protein. Use thick Greek yogurt, not regular yogurt. A thinner yogurt will result in a loose, unset mousse.

Protein Powder (30g) Unflavored works best for a clean strawberry flavor, but vanilla or strawberry protein powder can also be used. Avoid overly sweet or chalky powders as they will dominate the taste and texture.

Pinch of Salt This small addition enhances sweetness and balances the flavor. Do not skip it.

Sweetener (1 tbsp, optional) Adjust based on your taste and protein powder. Some protein powders are already sweet enough, so taste before adding more.

Optional Toppings

Fresh strawberries for texture and freshness
Low fat whipped cream for added creaminess

Step-by-Step Directions

Dissolve the Jelly

In a mixing bowl, pour the boiling water over the strawberry sugar-free jelly sachet. Stir thoroughly until fully dissolved. This step is critical. Any undissolved granules will affect the final texture.

Let It Cool Slightly

Allow the mixture to cool for a few minutes. It should still be liquid but not steaming hot. Adding yogurt to very hot liquid can cause separation.

Add the Greek Yoghurt

Spoon in the Greek yogurt and begin mixing gently. The mixture should start to thicken slightly and turn pale pink.

Add Protein Powder and Salt

Add your protein powder and a pinch of salt. Blend the mixture until completely smooth. The texture should be thick but pourable with no lumps.

Taste and Adjust Sweetness

Taste the mixture at this stage. If needed, add your sweetener and blend again briefly.

Transfer and Chill

Pour the mixture into a bowl. Cover and refrigerate for at least 3 hours, or until set. The mousse should be firm to the touch but still soft and scoopable.

Serve

Once set, give it a gentle stir if you prefer a softer texture. Top with fresh strawberries or whipped cream if desired.

Tips for Success

Fully dissolve the jelly. This is the most important step. I once rushed this and ended up with tiny rubbery bits throughout the mousse.
Let the jelly cool slightly before mixing. If it is too hot, it can thin out the yogurt and affect the set.
Use thick Greek yogurt only. Runny yogurt will not give you that mousse texture.
Blend thoroughly. Any lumps from protein powder will be very noticeable once set.
Do not reduce the chilling time. The mousse needs at least 3 hours to properly set and develop its texture.
If your mousse turns out too firm, it likely means too much jelly or not enough yogurt. You can fold in a bit more yogurt next time to balance it.

Frequently Asked Questions

Is this strawberry mousse keto-friendly?

Yes, with the right ingredients. Use sugar-free jelly and a low-carb protein powder. Net carbs typically fall around 10 to 12 grams per serving, depending on your brands.

Can I use flavored protein powder?

Absolutely. Vanilla or strawberry protein powder works well. Just be aware that sweeter powders may reduce the need for additional sweetener.

How long does it last in the fridge?

This mousse keeps well for up to 3 days when covered and refrigerated. The texture stays stable, though it may firm up slightly over time.

Can I freeze this mousse?

You can freeze it, but the texture will change. It becomes more icy and less creamy. If you do freeze it, let it thaw slightly before eating for a softer consistency.
