Ingredients

• Shelled unsalted pistachios: Fresh and high quality nuts make for the smoothest, creamiest paste
• Sugar: Balances the natural earthiness of pistachios and sweetens the mousse
• Heavy cream: Chilled and full fat for rich mousse and silky ganache
• Vanilla extract: Adds warmth and depth of flavor
• Almond extract: Optional but enhances the nutty undertones without overpowering
• Semisweet or dark chocolate chips: Provides a glossy, bittersweet ganache that contrasts the mousse’s delicacy
• Optional garnishes: Chopped pistachios add crunch, shaved chocolate or cocoa nibs bring texture, and whipped cream lends extra creaminess

Instructions

Make Pistachio Paste:

Cook pistachios and sugar in a food processor until you form a smooth thick paste scraping the sides occasionally to ensure everything blends evenly. This paste is the flavor heart of the mousse.

Whip the Cream:

Beat the chilled heavy cream until soft peaks form this makes the mousse light and airy. Add vanilla and if using almond extract and mix briefly to combine the flavors without deflating the cream.

Fold in Pistachio Paste:

Loosen the paste by mixing a bit of whipped cream into it then fold it gently into the remaining cream. Folding keeps the mousse airy while evenly distributing the pistachio flavor.

Fill the Glasses:

Spoon or pipe the mousse into 4 to 6 serving glasses. Smooth the tops if needed and refrigerate for 1 to 2 hours to allow it to set slightly and chill completely.

Make the Ganache:

Heat the 1/2 cup of heavy cream until it is steaming but not boiling then pour it directly over the chocolate chips. Let it rest for 1 to 2 minutes allowing the chocolate to melt then stir gently until smooth and glossy.

Add Ganache Layer:

Once slightly cooled but still pourable carefully pour the ganache layer over the chilled pistachio mousse. Return to the refrigerator and chill for at least 1 more hour so the ganache firms slightly while staying soft.

Garnish and Serve:

Just before serving top the mousse with chopped pistachios shaved chocolate cocoa nibs or a dollop of whipped cream. Serve chilled for the perfect balance of creamy and crunchy textures.

Pistachios are my favorite ingredient because they add that unique nutty sweetness that pairs beautifully with chocolate. One of my fondest memories is making this mousse with my grandmother who used to shell pistachios by hand while telling stories of her youth. It reminds me that the best desserts are those made with love and shared company.

Storage Tips

Store leftovers covered tightly in the refrigerator for up to 3 days. The mousse and ganache will maintain their texture and flavor if kept cold. Avoid freezing if you want to preserve the mousse’s delicate airy texture as freezing can sometimes cause slight separation after thawing.

Ingredient Substitutions

Cashews can replace pistachios for a milder but still creamy nut paste. Vanilla bean paste or scraped seeds offer a more intense vanilla flavor compared to extract. Use bittersweet chocolate if you prefer darker ganache with less sweetness. Coconut cream is a non dairy alternative to heavy cream but will change the flavor profile.

Serving Suggestions

Serve in elegant glasses or small jars for fuss free presentation. Add fresh berries or a drizzle of honey on top for added color and sweetness. Pair with a cup of espresso or a dessert wine for a restaurant style finish.

This pistachio mousse with chocolate ganache is an elegant make ahead dessert that feels special yet is simple to prepare. Chill well before serving for the best texture.
