How to Make Chocolate Hazelnut Tart

For the Crust:

Combine flour, sugar, salt and cubed butter in a bowl until mixture resembles coarse breadcrumbs, about 3 minutes by hand or pulse in a food processor.
Add egg yolk and a tablespoon of ice water, mixing gently until the dough just comes together, avoiding overwork to keep the crust tender and flaky.
Chill the dough wrapped in plastic for at least 30 minutes (or up to 2 hours), which firms the butter and prevents shrinkage during baking.
Roll out the chilled dough between parchment sheets to about ¼-inch thickness, then gently transfer into a 9-inch tart pan, trimming excess edges.
Blind bake the crust lined with parchment and pie weights at 350°F for 15 minutes, then remove weights and bake 5 more minutes until light golden brown.

For the Filling:

Toast hazelnuts on a baking sheet at 350°F for 10 minutes until fragrant and golden, then rub off skins with a towel and roughly chop.
Heat heavy cream in a small saucepan over medium heat until it just simmers, then immediately pour over chopped dark chocolate in a heatproof bowl.
Stir gently for about 1 minute until the chocolate melts smoothly, then whisk in butter, powdered sugar, and vanilla until glossy and lump-free.
Fold chopped toasted hazelnuts into the warm ganache, mix until evenly distributed, then pour filling into the hot tart shell.
Chill the filled tart in the refrigerator for at least 2 hours (or overnight) until the ganache sets firmly and the crust stays crisp before slicing.

Optional: top with a sprinkle of flaky sea salt before serving for a flavor pop.

Expert Tips for Chocolate Hazelnut Tart

Use cold ingredients: Keep butter and flour cold to ensure a flaky, tender crust that holds together without shrinking during baking.
Don’t overwork dough: Mix crust ingredients gently and just until combined to avoid a tough, dense base—patience is key for perfect texture.
Toast hazelnuts thoroughly: Proper toasting unlocks deep flavor and removes skins; don’t skip this step for that signature nutty note.
Warm ganache gently: Pour hot cream over chocolate to melt it without overheating; stirring slowly ensures a smooth, glossy filling.
Chill enough time: Allow the tart to set fully in the fridge so the filling firms and flavors meld, creating that irresistible, sliceable consistency.

Chocolate Hazelnut Tart Recipe FAQs

How do I know when the hazelnuts are perfectly toasted?
Toast your hazelnuts at 350°F for about 10 minutes until they emit a rich, nutty aroma and develop a golden-brown color. You’ll also notice their skins loosening, which you can gently rub off with a towel for smooth texture in the tart.

What’s the best way to store leftover Chocolate Hazelnut Tart?
Absolutely keep leftovers covered in the refrigerator, ideally in an airtight container or wrapped tightly with plastic wrap. This will keep your tart fresh and delicious for up to 4 days, preserving both the crisp crust and silky filling.

Can I freeze Chocolate Hazelnut Tart for later?
Very! Slice the tart before freezing, then wrap each piece tightly in plastic wrap and foil to protect against freezer burn. Store in the freezer for up to 2 months, and when ready to enjoy, thaw overnight in the fridge for the best texture and flavor.

Why is my tart crust sometimes tough instead of flaky?
This usually happens if the dough is overworked or too warm. To avoid this, work quickly with cold butter and flour, mixing just until the dough comes together. Chill the dough well before rolling it out and blind baking to keep that tender, flaky texture.

Is this Chocolate Hazelnut Tart safe for pets or those with nut allergies?
Since hazelnuts are a primary ingredient, this tart is not suitable for those with nut allergies or for pets. Always keep nut-based desserts well out of pets’ reach, as chocolate and nuts can be toxic to many animals. For allergen-free alternatives, try recipes without nuts and substitute safe ingredients accordingly.
