Dark Chocolate Pistachio Tart (Printer-friendly)
Crisp cocoa crust filled with silky dark chocolate ganache and topped with crunchy pistachios.
# What You Need:
→ Chocolate Tart Crust
01 - 1½ cups all-purpose flour
02 - ¼ cup unsweetened cocoa powder
03 - ½ cup powdered sugar
04 - ¼ teaspoon fine sea salt
05 - ½ cup (1 stick) unsalted butter, cold and cubed
06 - 1 large egg yolk
07 - 2–3 tablespoons cold water
→ Dark Chocolate Ganache Filling
08 - 9 oz high-quality dark chocolate (60–70% cocoa), finely chopped
09 - ¾ cup plus 2 tablespoons heavy cream
10 - 2 tablespoons unsalted butter, softened
11 - 1 teaspoon pure vanilla extract
→ Pistachio Topping
12 - ⅔ cup shelled pistachios, roughly chopped
13 - Flaky sea salt, to taste (optional)
# How to Make It:
01 - In a large mixing bowl, whisk together the all-purpose flour, cocoa powder, powdered sugar, and fine sea salt until evenly distributed.
02 - Add the cold cubed butter to the flour mixture. Using a pastry cutter or your fingertips, work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized pieces remaining.
03 - Add the egg yolk and 2 tablespoons of cold water. Mix gently until the dough just begins to come together. Add the remaining tablespoon of water only if needed. Shape into a flat disc, wrap tightly in plastic, and refrigerate for at least 30 minutes.
04 - On a lightly floured surface, roll the chilled dough to approximately ⅛ inch thickness. Carefully transfer it into a 9-inch tart pan, pressing firmly into the corners. Trim any excess dough from the edges and prick the base evenly with a fork. Chill for another 15 minutes.
05 - Preheat the oven to 350°F. Line the crust with parchment paper and fill with baking weights. Bake for 15 minutes, then remove the weights and paper. Continue baking for 8–10 minutes until the crust appears dry and set. Allow to cool completely in the pan.
06 - Place the finely chopped dark chocolate in a heatproof bowl. Heat the heavy cream in a saucepan over medium heat until it just begins to simmer. Immediately pour the hot cream over the chocolate and let it stand for 2 minutes. Stir gently from the center outward until smooth and glossy. Add the softened butter and vanilla extract, stirring until fully incorporated.
07 - Pour the ganache into the cooled tart shell, smoothing the surface with an offset spatula. Sprinkle the chopped pistachios evenly over the top and finish with a light pinch of flaky sea salt if desired.
08 - Refrigerate the tart for at least 2 hours, or until the ganache is firm and fully set.
09 - Remove the tart from the pan. For clean, professional edges, dip a sharp knife in hot water and wipe dry before each cut. Serve chilled or at cool room temperature.
# Expert Tips:
01 -
- The contrast between the snap of the chocolate pastry crust and the velvet ganache will ruin you for simpler desserts.
- It looks like it took all day but most of the time is just waiting for the fridge to do its work.
- Pistachios scattered on top turn a quiet bittersweet tart into something festive without any extra effort.
02 -
- If the ganache separates and looks oily instead of glossy, stir in a tablespoon of warm cream slowly and it should come back together.
- The tart shell must be completely cool before the ganache goes in or the chocolate will melt into the pastry and create a soggy layer.
- Chilling the finished tart for the full two hours is nonnegotiable because slicing too early gives you a beautiful but messy puddle.
03 -
- Chop the chocolate as uniformly as possible because uneven pieces melt at different rates and leave grainy lumps in your ganache.
- Toast the pistachios in a dry pan for three minutes before scattering them on top because the warmth wakes up oils you never knew were there.
