How to Make Strawberry Mousse

Mouse is a light and airy dessert – different than thick and creamy pudding, or custard, and definitely different than jello. Although it has components of all of these, the key is the whipping of ingredients to incorporate lots of air.

This mousse recipe has fresh strawberries as the base which is just a simple puree combining strawberries and honey. After your puree is made, you will whip both the egg whites and the heavy cream separately until they reach stiff peaks.

Most mousse recipes don’t add yogurt, but I wanted to boost the nutrition in this recipe and so it makes the perfect ingredient for that purpose.

After everything has been mixed separately, you will gently fold it all together. SO GENTLY!! You don’t want to break the air bubbles that make this mousse light, airy and deliciously smooth.

The last step is to refrigerate to let it set. Then serve it will fresh strawberries on top!

Where Does the Protein in Strawberry Mousse Come From?

This recipe doesn’t have protein powders, but uses whole foods that are naturally high in protein! The two protein sources are egg whites and Greek yogurt. Both of these not only contribute protein, but also give this mousse an amazing texture!

The egg whites make it airy and fluffy, and the Greek yogurt makes it creamy. Soooo good.

How Do I Thicken Mousse?

What if your mousse just isn’t as thick as you would like and you want to make it thicker? First, there are a few reasons that your mousse might be too runny:

  • The egg whites didn’t set properly. You want to beat your egg whites until they form a stiff peak. It can be tricky to tell the difference between soft peaks and stiff peaks. A stiff peak will stand straight up when you pull the mixture up. A soft peak will tend to flop over.
  • Cream wasn’t beat long enough. The same concept applies here as with the egg whites. Make sure you are beating it to the stiff peak stage.
  • The mousse gets overmixed. When you are folding the ingredients together, make sure you fold gently just until combined. If you stir or fold too much, it will break the air bubbles from the egg whites and your mousse could get a bit runny.

If you followed the recipe and none of those things are a problem in your mousse, there are a couple of options you can try to add thickening to the mousse.

  • Egg yolks. Egg yolks have a very strong thickening power and can be added to mouse to make it thicker. To do this, bring a pot half filled with water to a boil. Add 1 egg yolk to a stainless-steel bowl for each cup of finished mousse. Whisk the egg yolks until combined and heat them until they reach 160 F. Combine the egg yolks with the finished mousse.
  • Cornstarch. This is kind of a last option because it will turn your mousse into more of a pudding. To do this, mix 1/2 tablespoon of cornstarch with 1/2 tablespoon of cold milk for every 1 cup of finished mousse. Add the cornstarch slurry to a small amount of strawberry puree; then heat it until it thickens. Let it cool to room temperature before adding to your mousse.

How Long Does Mousse Take to Set in the Fridge?

For this mousse recipe, the ideal time is to let it set in the fridge for about 3-4 hours. You can check it earlier and test if it has set to your preference.

What Are the Basic Ingredients for Mousse?

Mousse is made up of just a few ingredients: the base, the aerator, the flavor enhancer, and the thickener. For this recipe, the base is the Greek yogurt, the aerator is the egg whites, the flavor enhancer is the strawberry puree and honey, and the thickener is heavy cream.

Can you make this without egg whites? If yes, how could the recipe be adjusted? Double heavy whipping cream? Not comfortable giving raw eggs to kids…

Hello! Yes, you could leave out the egg whites. We add them for extra protein. But we do use pasteurized eggs which are heated to kill any bacteria. 🙂

Is it at the end raw egg?, is it ok for kids?, looks like a great idea, but want to make sure, thanks and regards from Switzerland ??

I’ve been craving sweets lately which is a very slippery slope for me. But it’s also time to put together some healthy treats so I thought I’d try this very simple recipe. Not bad for 20 grams of protein!

I just recently had bariatric surgery and am in the Purée stage of my journey I was looking for high protein purées foods and this is what I landed on! It was so delicious, I made it with orange jello and Vanilla Unjury protein so it was like an Iran creamsicle! And it contained 13g it protein which was a nice way to start my day!

I agree. it’s so delish! This mousse recipe is based on fresh strawberries, which is just a simple puree that combines strawberries and honey. After your puree is made, beat both egg whites and cream separately until they reach stiff peaks.
