How to Make Pistachio Mousse with Chocolate Ganache
-
Blend the pistachios until finely ground in a food processor. If you’d like to add a finishing touch, reserve a few whole pistachios for garnish to elevate your dessert’s presentation.
-
Whip 1 cup of heavy cream in a mixing bowl until soft peaks form. Gradually incorporate the powdered sugar and vanilla extract, continuing to whip until the mixture holds stiff peaks. Set this delightful cream aside for later.
-
Bloom the gelatin, if using, by sprinkling it over 3 tablespoons of water in a small bowl. Let it sit for about 5 minutes. Then, heat it gently in the microwave for about 10 seconds until it’s fully dissolved.
-
Combine the ground pistachios with the remaining 1 cup of heavy cream in a separate bowl. If using gelatin, add it to this mixture. Gently fold in the whipped cream until everything is beautifully combined, being cautious not to deflate the airy mixture.
-
Spoon the luscious mousse into individual serving glasses or dishes. Refrigerate for at least 2 hours to let it set perfectly, creating a delightful texture that melts in your mouth.
-
Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer. This will be the base for your chocolate ganache.
-
Add the semi-sweet chocolate chips to the heated cream. Let them sit for a minute before stirring until the mixture is smooth and fully melted.
-
Cool the ganache slightly before using it to ensure it won’t melt the mousse once poured over it.
-
Spoon the chocolate ganache over the top of each mousse serving once it has set, creating a beautiful contrast between the green mousse and rich chocolate.
-
Garnish your dessert with whole pistachios or a sprinkle of crushed pistachios to add some crunch and make it visually appealing.

Chef's Helpful Tips
- When preparing the Pistachio Mousse with Chocolate Ganache, ensure your pistachios are finely ground to avoid a gritty texture in the mousse.
- Always whip your heavy cream to stiff peaks to maintain the airy consistency of the dessert, as under-whipping can lead to a flat mousse.
- If you’re using gelatin for added stability, remember to let it bloom fully before mixing it into the pistachio blend to ensure a smooth incorporation.
- Finally, allow the chocolate ganache to cool slightly before pouring it over the mousse, as a too-hot ganache can melt the delicate mousse underneath.
Pistachio Mousse with Chocolate Ganache Recipe FAQs
What kind of pistachios should I use?
Absolutely! For the best flavor, use unsalted, shelled pistachios. Fresh, high-quality nuts will enhance the mousse’s nutty essence. Look for a vibrant green color without any dark spots or signs of aging.
How do I store leftover mousse?
You can store leftover Pistachio Mousse covered with plastic wrap or in an airtight container in the fridge for up to 3 days. This helps maintain its creamy texture so you can enjoy it later without any loss in flavor!
Can I freeze pistachio mousse?
Yes, you can freeze the mousse! Transfer it to an airtight container and freeze for up to 2 months. To defrost, place it in the fridge overnight so it can slowly come back to its original creamy texture. I often freeze mine in individual portions for convenience!
What if my mousse doesn’t set properly?
If your mousse doesn’t set, it may be due to not folding the whipped cream gently enough or not allowing it to chill long enough. Make sure to fold gently to retain airiness. Also, chilling for at least 2 hours is essential for that perfect mousse consistency.
Is this recipe suitable for people with nut allergies?
This Pistachio Mousse with Chocolate Ganache is not suitable for individuals with nut allergies, as it contains pistachios. If you’re looking for a nut-free alternative, consider using pureed fruits like bananas or mangoes instead of pistachios to create a different flavor profile.
