Pistachio Mousse with Chocolate Ganache

Pistachio mousse with chocolate ganache is an elegant layered dessert I love making when I want something creamy, nutty, and indulgent. The smooth pistachio mousse pairs beautifully with the rich, glossy ganache, creating a dessert that feels both luxurious and comforting. I find it perfect for dinner parties or special occasions, yet simple enough to make ahead.

Why You’ll Love This Recipe

I like how this recipe combines two textures the velvety richness of chocolate ganache and the light, airy pistachio mousse. The flavors balance beautifully: the nuttiness of pistachios softens the intensity of dark chocolate, while mascarpone adds a creamy depth. I also enjoy how stunning it looks when garnished, making it a show-stopping dessert without being overly complicated.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

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 (1 ¼ 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
A pinch of salt

GARNISH (OPTIONAL)
Chopped roasted pistachios
Chocolate curls or shavings
Edible gold dust or sea salt flakes

Directions

1. I start by making the ganache. I heat the cream until just simmering, then pour it over the chopped dark chocolate.
2. I let it sit for a minute before stirring until smooth. For extra shine, I whisk in the butter. I set it aside to cool slightly.
3. For the pistachio mousse, I blend the pistachios with sugar until finely ground.
4. In a separate bowl, I whip the cold cream until soft peaks form.
5. I beat the mascarpone with vanilla and salt until smooth, then fold in the pistachio mixture.
6. I gently fold in the whipped cream until airy and well combined.
7. To assemble, I spoon or pipe a layer of ganache into serving glasses, followed by pistachio mousse.
8. I chill for at least 1 hour before serving, then garnish with roasted pistachios, chocolate curls, or a touch of edible gold.

Servings and Timing

This recipe makes about 6 servings. It takes around 30 minutes to prepare, plus at least 1 hour of chilling time.

Variations

Sometimes I use white chocolate ganache instead of dark for a sweeter, creamier contrast. I’ve also folded a little orange zest into the mousse for a citrus twist. If I want a lighter dessert, I swap mascarpone for Greek yogurt. For a nut-free option, I replace pistachios with almonds or hazelnuts.

Storage/Reheating

I keep the mousse in the refrigerator for up to 3 days, covered with plastic wrap or stored in airtight containers. I don’t freeze it since the texture changes, and there’s no need to reheat—it’s best served chilled.

FAQs

Can I make this dessert ahead of time?

Yes, I like to prepare it a day ahead since the flavors develop beautifully in the fridge.

Do I need to peel the pistachios?

I prefer peeling them for a smoother texture and brighter green color, but it’s optional.

Can I use store-bought pistachio paste?

Yes, I sometimes use it to save time, adjusting sugar to taste.

What if I don’t have mascarpone?

I substitute with cream cheese or even Greek yogurt for a lighter version.

Can I use milk chocolate instead of dark?

Yes, though it will make the ganache sweeter and less intense.

How do I get the mousse extra light?

I take care not to overmix when folding in the whipped cream—it keeps the mousse airy.

Can I serve this in a large dish instead of glasses?

Yes, I layer it in a trifle dish or small baking dish when serving a crowd.

How can I make it dairy-free?

I use coconut cream instead of heavy cream and a dairy-free cream cheese substitute.

What’s the best garnish for presentation?

I love chopped pistachios for crunch and chocolate curls for elegance. A touch of gold dust makes it extra special.

Can I freeze the mousse?

I don’t recommend freezing since it loses its light texture once thawed.

Conclusion

Pistachio mousse with chocolate ganache is a dessert I always turn to when I want something rich yet refined. I love how the nutty pistachios complement the silky chocolate, and the make-ahead factor makes it stress-free for entertaining. Each spoonful feels indulgent, balanced, and truly unforgettable.
