How to Make Pistachio Mousse with Chocolate Ganache
-
Blend Pistachios: In a food processor, blend the unsalted pistachios until they’re finely ground. Set aside some pistachios for garnishing later to add a nice touch.
-
Whip Cream: In a mixing bowl, whip 1 cup of heavy cream to soft peaks. Gradually add the powdered sugar and vanilla extract, continuing to whip until stiff peaks form—this should take about 4-5 minutes.
-
Prepare Gelatin: If using, sprinkle gelatin over 2 tablespoons of water and let it bloom for a few minutes. Then, gently heat this mixture on low until the gelatin dissolves completely.
-
Combine Mixtures: In a large bowl, mix the ground pistachios with the remaining whipped cream. Pour in the melted gelatin if you’re using it, and gently fold in the whipped cream until well combined—be careful not to deflate the mixture.
-
Chill Mousse: Spoon the mousse mixture into your desired serving dishes. Refrigerate for at least 2 hours or until the mousse is set.
-
Make Ganache: In a saucepan, heat ½ cup of heavy cream over medium heat until it simmers. Remove from heat and stir in the semi-sweet chocolate chips until the ganache is smooth and glossy.
-
Cool Ganache: Allow the ganache to cool slightly, ensuring it’s warm but not hot enough to melt the mousse when topped.
-
Assemble: Once the mousse has set, carefully spoon the cooled ganache over the top of each mousse dish, creating a lovely layer of chocolate.
-
Garnish: Optionally, sprinkle whole or crushed pistachios on top for an extra crunch and eye-catching presentation.
-
Serve: Enjoy your delectable dessert immediately or keep it refrigerated until you’re ready to impress your guests!

Pistachio Mousse with Chocolate Ganache Recipe FAQs
How do I select ripe pistachios for the mousse?
When choosing pistachios, look for nuts that are bright green and firm to the touch. Avoid any that are grayish or have dark spots, as these could indicate staleness. Fresh pistachios should have a pleasant, nutty aroma.
How do I store leftover Pistachio Mousse with Chocolate Ganache?
Store any leftovers in an airtight container in the refrigerator, where they will stay fresh for up to 3 days. Keep the mousse and ganache separate if possible to retain the texture and flavor of both elements.
Can I freeze the Pistachio Mousse?
Absolutely! To freeze the mousse, transfer it to an airtight container and place it in the freezer. It can last up to 2 months. When you’re ready to enjoy, simply transfer it to the refrigerator and allow it to thaw overnight before serving.
What should I do if my mousse is too runny?
If your mousse is too runny, it might be due to under-whipping the cream or insufficient gelatin. For a thicker texture, you can gently fold in more whipped cream to achieve a better consistency or increase the amount of gelatin (bloom 1 additional teaspoon in the same way). Always ensure gelatin is properly dissolved before adding.
Is this dessert safe for nut allergies?
The Pistachio Mousse contains nuts, so it is not safe for those with nut allergies. However, you can create a nut-free version by substituting pistachios with a seed butter like sunflower seed butter for a similar creamy texture. Always double-check any substitutes you use to ensure they are safe for your dietary needs.
How can I make this dessert more decorative?
To enhance the presentation, consider garnishing the mousse with a sprinkle of finely chopped pistachios just before serving. Additionally, a drizzle of melted chocolate or a few fresh berries can elevate the visual appeal and add a touch of color.
