Cooking Steps
Toast Hazelnuts:
- Preheat your oven to 350°F (175°C).
- Spread the whole hazelnuts on a baking sheet.
- Toast for 8-10 minutes, stirring halfway, until fragrant and their skins loosen.
- Rub the hot nuts in a clean kitchen towel to remove most of the skins (don't worry if some remain).
- Let cool completely, then finely grind ½ cup for the crust (a food processor works well) and roughly chop ¼ cup for garnish.
- In a large bowl, whisk together the flour, powdered sugar, and salt.
- Add the cold, cubed butter and cut it into the flour mixture using a pastry blender, your fingertips, or a food processor, until it resembles coarse crumbs with some pea-sized butter pieces.
- Stir in the finely ground toasted hazelnuts.
- Add the egg yolk and 1 tablespoon of ice water, mixing until the dough just starts to come together.
- If too dry, add more ice water, ½ teaspoon at a time, until the dough forms a ball.
- Flatten the dough into a disk, wrap tightly in plastic wrap, and refrigerate for at least 30 minutes (or up to 2 days).
- Chilling helps prevent shrinking and makes it easier to roll.
- Lightly grease a 9-inch (23 cm) tart pan with a removable bottom.
- On a lightly floured surface (or between two sheets of parchment paper), roll out the chilled dough into a 12-inch (30 cm) circle. Carefully transfer the dough to the prepared tart pan, gently pressing it into the bottom and up the sides.
- Trim any excess dough from the edges.
- Prick the bottom of the crust all over with a fork.
- Line the crust with parchment paper and fill with pie weights, dried beans, or rice.
- Bake for 15-20 minutes until the edges are lightly golden.
- Remove the parchment and weights, then bake for another 5-10 minutes until the bottom is dry and lightly golden.
- Let cool completely on a wire rack.
- Place the chopped dark chocolate in a heatproof bowl.
- In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer (small bubbles appear around the edges).
- Remove from heat and pour the hot cream over the chopped chocolate.
- Let sit for 5 minutes without stirring.
- After 5 minutes, gently whisk the chocolate and cream together, starting from the center and working outwards, until smooth and glossy.
- Stir in the softened butter, vanilla extract, pinch of salt, and optional Nutella until fully incorporated and the ganache is silky smooth.
- Pour the chocolate hazelnut ganache into the cooled, blind-baked tart crust.
- Gently tap the tart pan on the counter a few times to release any air bubbles and ensure an even surface.
- Refrigerate the tart for at least 3-4 hours, or preferably overnight, until the filling is completely set.
- Once the tart is set, carefully remove it from the tart pan.
- Garnish with the roughly chopped toasted hazelnuts and a light dusting of cocoa powder, if desired. Slice with a warm, sharp knife for clean cuts.
- Serve at room temperature for the best texture and flavor.
