This Keto Lemon Mousse is smooth, sweet, tangy and absolutely yummy! Not to mention it's low carb and incredibly simple and quick to make.
Why You'll Love This Lemon Mousse Recipe
One of my favorite desserts to make has got to be mousse. It's such a wonderfully smooth, creamy, and simple dessert to make that I find myself making it on a fairly regular basis. Not to mention it's quite easy to make the dessert low carb, which is great for those of us living a keto lifestyle.
One of my favorite things about this Keto Lemon Mousse is that it only takes five ingredients to make. You'll most likely have most of the ingredients on hand, and if not, it will cost you next to nothing to grab the ingredients at the store.
This recipe only takes a few minutes to whip together. The longest part is letting it refrigerate for a couple of hours before consuming, but let me assure you, it's well worth the wait!
I always like to make a large batch so that I can have some now, then put the rest back in the fridge for later use. I normally like it to last a few days before I end up creating another dessert to curb my sweet tooth.
How To Make Keto Lemon Mousse
- In a stand mixer with a paddle attachment, mix together all ingredients until smooth and creamy.
- Refrigerate for 1-2 hours and serve.
Tips for Making Keto Lemon Mousse
- Mascarpone cheese is sweet, soft cheese. If you can't find it, substitute it with ricotta cheese.
- If you don't like the flavor of lemon, you can also make a chocolate mousse that's very similar to the texture and carb count of this lemon version.
- You can vary the flavors for this mousse, by using orange extract and orange zest for example. Almond mousse with just the extract is also fabulous.
- This is a very rich sweet treat. Start with 1/4 cup at most per person as it can be very filling.
- You can also freeze this in small truffle molds. When it's frozen, pop them out of the molds and store them in the freezer. It's great for portion control!
How Long Does It Last?
This mousse can last several days in the refrigerator in an air-tight container. For best results, try to enjoy within 3-4 days before the ingredients begin to separate.
What To Eat With This Low Carb Mousse
Lemon mousse is VERY filling, so I often just use a spoon to enjoy it. Adding anything else seems to be overindulgent. That being said, if you're consuming less than a serving, it can be quite tasty when it is used as a "frosting" on my keto pound cake!

This is my favorite keto recipe to date! It makes me want to stay on keto forever just so I can eat this. It reminds me of a Greek yogurt texture! Like manna from heaven. 🙂 I used a Vitamix to mix it and it thickened up super fast. Thank you soo much!
Linda
Tasted delicious, but did not set up. With 5 ingredients and 2 steps, I figured this was a fool-proof recipe, but my mousse did not set up. It was a thick soup, even after 2 hours in the fridge. Thoughts? "Mix until smooth and creamy" took less than 2 minutes. Should I have mixed longer?

I’m wondering if you didn’t whip it long enough. The thick cheese and the cream thicken when whipped.
Cori
It's not often I use my Meyer lemons on an untested recipe, but I'm so glad I did! I used the best from one of the lemons, too, and this was perfect! I used Swerve instead of Truvia. I'll be making this again soon!

Hi Jody, the recipe uses Mascarpone cheese, not ricotta
Lynne
Are you sure the recipe uses1CUP
Cause that has 192 net grams carbs. Divide that by 4 serves & ive just been well & truly thrown out of Ketosis or am I wrong??
URVASHI PITRE
Hi Lynne, 1 cup of mascarpone cheese has zero carbs according to MyFitnessPal
Jodi
I made this last night using Ricotta cheese, and it is not thick like the picture shows. What did I do wrong and can it be thickened up at this point?
elf
What can be used rather than Truvia? I don't like the "natural flavors" which could be anything. Thank you in advance! elf
