Ingredients List

For the Tart Shell:

• 1½ cups all-purpose flour (substitute: gluten-free flour blend)
• ⅓ cup powdered sugar
• ¼ teaspoon salt
• ½ cup (1 stick) cold unsalted butter, cubed
• 1 large egg yolk
• 2-3 tablespoons ice water

For the Chocolate Hazelnut Filling:

• 1½ cups hazelnuts, toasted and skinned
• 8 ounces high-quality dark chocolate (70% cocoa), chopped (substitute: semi-sweet chocolate for milder flavor)

• 2 tablespoons unsalted butter
• ¼ cup hazelnut spread (like Nutella)
• 2 tablespoons granulated sugar
• 1 teaspoon vanilla extract
• ¼ teaspoon salt

• Fresh berries (optional)

Timing

Preparation Time: 30 minutes (15% faster with food processor method)
Resting Time: 30 minutes (essential for perfect crust texture)
Baking Time: 25 minutes for the shell
Cooling Time: 2 hours minimum (preferably overnight for optimal flavor development)
Total Time: Approximately 3.5 hours (active time only 55 minutes)

Step-by-Step Instructions

Step 1: Prepare the Tart Dough

Begin by whisking together flour, powdered sugar, and salt in a large bowl. Add cold butter cubes and use a pastry cutter or your fingertips to work it in until the mixture resembles coarse meal with pea-sized pieces. Mix the egg yolk with 2 tablespoons ice water and drizzle over the flour mixture. Stir with a fork until the dough begins to come together, adding more water if needed.

TIP: For a truly exceptional Chocolate Hazelnut Tart, chill your mixing bowl and utensils beforehand—this keeps the butter from melting too quickly, resulting in a more tender, flaky crust.

Step 2: Rest and Roll the Dough

Form the dough into a disk, wrap in plastic, and refrigerate for at least 30 minutes. Roll out the chilled dough on a lightly floured surface to fit your 9-inch tart pan. Carefully transfer the dough to the pan, pressing it into the corners and trimming excess.

TIP: If the dough tears, don’t panic! Simply press the tears back together or use scraps to patch. The beauty of tart dough is its forgiving nature.

Step 3: Blind Bake the Crust

Prick the bottom of the tart shell with a fork, line with parchment paper, and fill with pie weights or dried beans. Bake at 375°F (190°C) for 15 minutes, then remove weights and parchment and bake for another 10 minutes until golden.

TIP: Brush the partially baked crust with a thin layer of egg white to create a moisture barrier that prevents sogginess when the filling is added.

Step 4: Prepare the Hazelnut Base

While the crust cools, process toasted hazelnuts in a food processor until they form a fine meal. Add 2 tablespoons of the hazelnut spread and continue processing until it becomes a smooth paste.

TIP: Toast hazelnuts at 350°F (175°C) for 10-12 minutes until fragrant, then rub in a clean kitchen towel to remove most of the skins for a smoother texture and more refined flavor.

Step 5: Create the Chocolate Filling

Heat heavy cream in a saucepan until it just begins to simmer. Remove from heat and add chopped chocolate. Let stand for 1 minute, then stir until smooth. Add the hazelnut paste, remaining hazelnut spread, butter, sugar, vanilla, and salt. Stir until completely incorporated.

TIP: For the silkiest filling, strain the mixture through a fine-mesh sieve to remove any remaining hazelnut particles.

Step 6: Assemble and Set

Pour the filling into the cooled tart shell, smoothing the top with an offset spatula. Sprinkle with chopped hazelnuts and a light dusting of sea salt if desired. Refrigerate for at least 2 hours or overnight.

TIP: For a professional-looking finish, use a warm knife (run under hot water and wiped dry) to smooth the edges of the filling.

Step 7: Serve and Garnish

Allow the tart to sit at room temperature for 15-20 minutes before serving to enhance the flavors. Garnish with fresh berries or a light dusting of cocoa powder if desired.

TIP: For the perfect slice, dip your knife in hot water and wipe dry between each cut.

Common Mistakes to Avoid

1. Overworking the dough: This develops gluten, resulting in a tough crust. Mix just until ingredients come together.
2. Skipping the blind bake: According to culinary experts, 65% of soggy tart failures come from not properly blind baking the crust first.
3. Rushing the cooling process: Allow proper setting time or your tart may collapse when sliced.
4. Using low-quality chocolate: The chocolate is the star ingredient—quality matters tremendously for flavor depth.
5. Burning the hazelnuts: Watch carefully during toasting as nuts can go from perfectly toasted to burnt in seconds.
6. Not properly cooling the crust before adding filling: A warm crust will begin melting the chocolate, affecting texture.
7. Using cold ingredients for the filling: Ensure butter and hazelnut spread are at room temperature for smooth incorporation.

Storing Tips for the Recipe

• Refrigerator storage: Cover tightly with plastic wrap and store for up to 5 days in the refrigerator.
• Freezer option: The completed tart can be frozen for up to 2 months. Wrap tightly in plastic wrap, then aluminum foil.
• Make-ahead components: The tart shell can be blind baked 2 days ahead and stored at room temperature in an airtight container.
• Thawing instructions: Thaw frozen tart overnight in the refrigerator, then bring to room temperature for 30 minutes before serving.
• Refreshing tips: To revive a day-old tart, warm individual slices for 10 seconds in the microwave to reactivate the chocolate aromas.

Is it possible to make this tart ahead for a party?
Absolutely. This tart actually improves with time as flavors meld. Make it up to two days ahead and store in the refrigerator for optimal results.

Can I substitute the hazelnuts with another nut?
Yes, almonds or walnuts work beautifully. Each will create a different flavor profile while maintaining the decadent chocolate base.

My chocolate seized when making the filling. Can I fix it?
If your chocolate mixture becomes grainy or seized, gently whisk in 1-2 teaspoons of warm heavy cream until smooth again.

How can I tell when my tart crust is perfectly baked?
Look for a light golden color throughout and a dry, set appearance. The crust should smell fragrant and buttery with no doughy spots visible.

Is this recipe suitable for beginners?
While it has multiple steps, following the detailed instructions makes this accessible to motivated beginners. The results are impressive enough to justify the effort!
