A few winters back, during a quiet evening at our cabin in the mountains, I decided to experiment with a dessert that felt both comforting and elegant. My husband was reading by the fire, the grandkids were tucked in after a long day of sledding, and the world outside was blanketed in snow.
The pantry was simple—some dark chocolate, a bag of pistachios, and a little mascarpone left from a cheesecake I’d made earlier that week. I wanted something light but luxurious, sweet but not cloying. So I started stirring, whipping, and layering until the kitchen filled with the scent of warm chocolate and toasted nuts.
That’s how this Pistachio Mousse with Chocolate Ganache was born. It’s one of those desserts that looks like it came from a fancy patisserie, but it’s actually quite straightforward to make. The ganache gives you that deep, silky chocolate base, while the mousse feels like a cloud—nutty, creamy, and just a bit indulgent.
I’ve made it many times since, and it never fails to draw smiles around the table. It’s perfect for family dinners, holidays, or even a quiet evening when you want something special without the fuss.

Key Ingredients
For the Chocolate Ganache:
- 200g (7 oz) dark chocolate (60–70% cocoa), chopped
- 200ml (¾ cup + 1 tbsp) heavy cream
- 1 tbsp unsalted butter (optional, for extra shine)
For the Pistachio Mousse:
- 150g (1¼ cups) shelled pistachios, unsalted
- 3 tbsp granulated sugar
- 1 tsp pure vanilla extract
- 250ml (1 cup) heavy cream, cold
- 100g (½ cup) mascarpone cheese or cream cheese, softened
- Pinch of salt
Optional Garnish:
- Chopped roasted pistachios
- Chocolate curls or shavings
- Edible gold dust or sea salt flakes
Tools Needed
- Food processor or high-speed blender
- Mixing bowls
- Electric mixer or whisk
- Saucepan
- Heatproof bowl
- Rubber spatula
- 6 small serving glasses
Cooking Instructions
Step 1: Prepare the Chocolate Ganache
Heat the cream over medium heat until it just begins to simmer—avoid boiling. Pour it over the chopped dark chocolate in a heatproof bowl and let it sit for one minute.
Stir slowly until the mixture turns glossy and smooth. Add butter if you’d like a shinier finish. Spoon the ganache into six small serving glasses, filling them about one-quarter full. Chill while you make the mousse.
Step 2: Make the Pistachio Paste
If you want a brighter green color, blanch the pistachios by boiling them for one minute, then plunging them into ice water and peeling off the skins. Pat them dry. In a food processor, blend pistachios with sugar, salt, and vanilla extract until thick and smooth. Add a teaspoon or two of cream if needed to achieve a spreadable consistency.
Step 3: Whip the Mousse
In a chilled bowl, whip the cold heavy cream to soft peaks. In another bowl, beat mascarpone until smooth, then mix in the pistachio paste. Gently fold the whipped cream into the pistachio mixture in two additions, keeping it light and airy.
Step 4: Assemble the Layers
Once the ganache is set, spoon or pipe the pistachio mousse on top. Smooth the surface with the back of a spoon. Cover lightly with plastic wrap and refrigerate for at least two hours, or until firm and chilled.
Step 5: Garnish and Serve
Before serving, top each glass with chopped roasted pistachios, chocolate curls, and a touch of gold dust or sea salt flakes if you like a bit of sparkle. Serve chilled with small dessert spoons.

Mistakes to Avoid & Solutions
Overheating the Cream: If the cream boils, it can scorch or split the chocolate. Heat just until it starts to steam.

Deflated Mousse: Fold the whipped cream gently to keep it airy. Avoid stirring too aggressively.

FAQs
1. Can I use white chocolate instead of dark for the ganache?
Yes, but it will make the dessert much sweeter. Reduce sugar in the mousse slightly to balance it.
2. Can I substitute mascarpone with cream cheese?
Absolutely. Cream cheese gives a slightly tangier flavor, which pairs well with pistachio.
3. Do I need to peel the pistachios?
Not necessarily. Peeling just improves color and smoothness, but unpeeled nuts add a rustic touch.
4. Can I prepare it a day in advance?
Yes, it actually tastes better after chilling overnight as the flavors meld beautifully.
5. How can I make it dairy-free?
Use coconut cream instead of heavy cream and a dairy-free chocolate. The flavor will be slightly tropical but still delicious.
Tips & Tricks
Toast the pistachios lightly before blending to deepen their flavor.
Chill mixing bowls and beaters before whipping cream—it helps achieve soft peaks faster.
Use high-quality chocolate for the ganache; it makes a noticeable difference.
Don’t rush the chilling time—this dessert sets beautifully when given enough time.
For an elegant presentation, use a piping bag to layer the mousse neatly.
Recipe Variations
Pistachio-White Chocolate Mousse: Replace the dark chocolate ganache with a layer of melted white chocolate for a sweeter contrast.
Citrus Twist: Add ½ teaspoon of orange zest to the mousse for a refreshing hint.
Coffee Infused: Stir 1 teaspoon of espresso powder into the ganache for mocha notes.
Berry Delight: Add a spoonful of raspberry compote between the layers for a fruity surprise.
Nut-Free Version: Swap pistachios with sunflower seed butter or roasted cashews for a similar creamy result.
