Dark Chocolate Pistachio Tart (Print Version)
Crisp cocoa shell 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 - ¼ cup powdered sugar
04 - ¼ teaspoon fine sea salt
05 - ½ cup unsalted butter, cold and cubed
06 - 1 large egg yolk
07 - 2 to 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 - ½ cup plus 2 tablespoons shelled pistachios, roughly chopped
13 - Flaky sea salt, optional
# Directions:
01 - In a large mixing bowl, whisk together the all-purpose flour, cocoa powder, powdered sugar, and fine sea salt until evenly combined.
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 to the crumb mixture. Mix gently until the dough just comes together, adding the remaining tablespoon of water if the dough feels too dry.
04 - Shape the dough into a flat disc, wrap tightly in plastic wrap, and refrigerate for at least 30 minutes until firm.
05 - On a lightly floured surface, roll the chilled dough out to an even thickness large enough to fit a 9-inch tart pan. Gently press the dough into the bottom and up the sides of the pan. Trim any excess edges and prick the base evenly with a fork. Refrigerate for 15 minutes.
06 - Preheat the oven to 350°F. Line the tart crust with parchment paper and fill with baking weights or dried beans. Bake for 15 minutes, then carefully remove the weights and parchment. Continue baking for 8 to 10 minutes until the crust looks dry and set. Allow to cool completely in the pan.
07 - 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 around the edges. Remove from heat immediately and pour the hot cream over the chocolate. Let it stand for 2 minutes to melt the chocolate.
08 - Stir the chocolate and cream mixture gently starting from the center and working outward until smooth and glossy. Add the softened butter and vanilla extract, stirring until fully incorporated and the ganache has a silky texture.
09 - Pour the finished ganache into the completely cooled tart shell, using a spatula to smooth the top into an even layer.
10 - Sprinkle the roughly chopped pistachios evenly over the surface of the ganache. Add a light pinch of flaky sea salt if desired to enhance the flavors.
11 - Refrigerate the assembled tart for at least 2 hours until the ganache is fully set and firm to the touch.
12 - Remove the tart from the pan and transfer to a serving plate. Dip a sharp knife in hot water and wipe dry before each cut for clean, professional-looking slices.
# Expert Tips:
01 -
- The cocoa laced crust doubles down on chocolate flavor in a way that a plain pastry shell never could, and it crisps up beautifully if you give it enough chill time.
- Ganache this rich makes people close their eyes when they take the first bite, and the pistachios on top add a crunch that keeps every slice interesting from start to finish.
02 -
- If the dough warms up while you are rolling it, slide it onto a baking sheet and chill it for ten minutes before trying again because soft dough will tear and shrink in the oven.
- The ganache must go into a completely cooled shell, otherwise the butter in the crust will melt and the whole thing turns greasy at the base.
03 -
- Chop the chocolate as finely and evenly as you can because large chunks will refuse to melt and leave grainy lumps in your silky ganache.
- Toast the pistachios in a dry pan for three or four minutes before scattering them on the tart to wake up their flavor and deepen the crunch.
