Protein Lemon Mousse Is Easy
If you have not yet tried your hand at making homemade mousse, then let me encourage you not to feel intimidated.
You don’t need a lot of fancy ingredients. And you don’t need tons of special equipment.
All you need is a great creamy base and some tasty flavorings.
This Protein Lemon Mousse with Yogurt is definitely both of those things: creamy and flavorful, with just the right amount of lemon zing.
(If you need a confidence boost, though, let me suggest that you start with our recipe for BEST Chocolate Avocado Mousse with Raw Cacao Powder and Honey (Keto-Friendly) because it takes significantly less time than this recipe and is made in the blender.)
Making Lemon Mousse with Yogurt
The base for this tasty protein mousse recipe is Greek yogurt.
Packed with protein, Greek yogurt supports bone health and also boosts good gut bacteria (source).
It also means that, even if you don’t have heavy whipping cream in your fridge, you can still make a batch of tasty homemade mousse whenever the craving strikes.

What Is in This Healthy Mousse Recipe?
Greek yogurt.
One of my favorite benefits of Greek yogurt is the boost it gives to good gut bacteria.
But that is not the only great thing about this delicious dairy. “Other benefits of Greek yogurt include boosting bone health, building muscle mass, and lowering the risk of certain health conditions” (source).
Egg white.
While I usually prefer to use whole eggs in order to gain all the nutrients contained in them, using egg whites is a great way to up the protein content in a recipe.
According to Healthline, “Egg whites…provide a ‘complete’ protein, which means the protein contains all nine essential amino acids in the amounts your body needs to function at its best.”
Raw organic honey.
My family loves the delicious taste of raw honey. But that is not the only reason that we prefer to use it in recipes like this.
“Raw honey is unpasteurized and contains more beneficial nutrients than pasteurized honey varieties, including compounds containing antioxidants. Raw honey may have antibacterial, antifungal, anticancer, and wound-healing properties” (source).
Lemon juice.
Real, freshly-squeezed lemon juice is best in this recipe. It helps regulate blood sugar, which is a bonus when using it in dessert recipes especially (source).
Sea salt.
Sea salt contains minerals that are not always present in typical table salt. If you want to read more about this, Dr. Axe provides an extensive list of benefits of sea salt in his article “Sea Salt vs. Table Salt.”
Important Note about Making Lemon Mousse with Egg Whites
When using raw egg whites in a recipe, it is important to make sure that they are heated up to the right temperature to kill any bacteria.
According to the North Dakota State University website, “Eggs can be “pasteurized” by holding them at a temperature of 140 degrees Fahrenheit for 3.5 minutes.”
If you have any hesitancy about whether your egg whites are properly cooked or not, use a candy thermometer to test the temperature.

Tools Needed
You will need this equipment to make this protein lemon mousse recipe:
- a stand mixer (easiest) or hand-held mixer (more time involvement)
- a whisk (if not using a hand-held mixer)
- a spatula
- a double boiler (or a bowl and saucepan that fit well together)
- individual ramekin cups
Ingredients for Protein Lemon Mousse with Yogurt
- 2 egg whites
- 1/4 cup raw organic honey
- pinch of sea salt
- 1 1/2 cups Greek yogurt
- 1 Tbsp. freshly-squeezed lemon juice
- Lemon zest, to garnish

How to Make Protein Lemon Mousse
Step One: Set up a double-boiler. (If you don’t have one, then fit a heat-proof mixing bowl over a saucepan filled with water, making sure that the bowl does not touch the water.)
Step Two: Prepare a stand mixer by fitting it with a whisk attachment.
Step Three: Over medium-low heat, warm the egg whites, honey, and pinch of sea salt in the double boiler. Whisk constantly so that the egg whites do not cook unevenly or become hard. (I use a whisk and mix quickly, but you can use a hand-held mixer, if desired.) Continue whisking and cooking until the honey is dissolved (at least 3 1/2 minutes).
Step Four: Quickly transfer the egg white mixture to the stand mixer. Beat on high speed until stiff peaks form. This may take anywhere from ten to thirty minutes, which is why I highly recommend using a stand mixer for this part of the recipe rather than using a hand-held mixer. (This is similar to the process of making meringue. When I make this, sometimes the egg whites do not form stiff peaks. However, they still thicken, and the mousse still turns out fine.)
Step Five: Turn off the stand mixer. Fold in the Greek yogurt and lemon juice.
Step Six: Spoon into serving dishes (like individual-sized ramekins or small mugs). Refrigerate for at least two hours.
Step Seven: Before serving, garnish with lemon zest.
Storage Instructions
This protein lemon mousse is best served immediately. However, you can make it ahead of time and store it in the refrigerator for a few hours.
If you have leftover mousse, store it in an airtight container in the refrigerator for a few hours up to a day. Because of the egg white content in the recipe, it may not be safe to store it longer than a day.

Tips and Tricks (and Encouragement)
- Whisk the egg whites constantly while cooking.
- If you see a few bits of cooked egg whites while whisking them, don’t despair. I have still successfully made this recipe with those little bits present, and no one could tell.
- Use a stand mixer to simplify the process of whipping the egg whites.
- If your egg whites still haven’t reached a stiff peak consistency after whisking them in a mixer for 20 to 30 minutes, don’t give up. As long as the eggs have thickened somewhat and you are using a thick Greek yogurt, your mousse can still turn out fine. It just may be a little on the thinner side and less of the “fluffy” type.
- Use a candy thermometer to test the temperature of the egg whites. (Remove them from the heat while doing this so that they don’t accidentally cook.)
- Add lemon zest to the top of the lemon mousse for a pretty garnish and a bit of flavor enhancement.
- Store the lemon mousse for only a few hours up to one day in the fridge to avoid spoilage.
