  • Granulated Sugar – Sweetens the tart without overpowering the chocolate; regular white sugar works well.

For the Filling

  • Toasted Hazelnuts – Adds delightful nuttiness; you can use pre-toasted or finely chop for texture.
  • Dark Chocolate (70% cocoa or higher) – Essential for a deep chocolate flavor; choose high-quality for the best ganache experience.

  • Eggs – Binds the filling together and improves texture; use large eggs for consistency.

Enjoy crafting your Chocolate Hazelnut Tart with these ingredients that combine beautifully to create a show-stopping dessert!

How to Make Chocolate Hazelnut Tart

  1. Prepare the Crust: Preheat the oven to 350°F (175°C). In a large bowl, mix together the flour, cocoa powder, and sugar. Cut in the unsalted butter until the mixture resembles coarse crumbs. Press this mixture firmly into the bottom and up the sides of a tart pan, then bake for 15 minutes until set.
  2. Toast Hazelnuts: While the crust is cooling, spread the hazelnuts evenly on a baking sheet. Toast them in the oven for about 10 minutes until golden brown but not burned, stirring halfway through to ensure even toasting.
  3. Make the Ganache: In a small saucepan over low heat, combine the heavy cream and chopped dark chocolate. Stir until melted and smooth. Allow the mixture to cool slightly, then whisk in the eggs until fully combined for a silkier texture.
  4. Assemble the Tart: Sprinkle the toasted hazelnuts evenly over the cooled tart shell. Carefully pour the ganache mixture over the nuts, ensuring even coverage.
  5. Final Bake: Place the assembled tart back in the oven and bake for an additional 20-25 minutes. The filling should be set yet slightly wobbly in the center.
  6. Chill and Serve: Let the tart cool completely at room temperature. Once cooled, refrigerate for at least two hours or overnight to enhance the flavors. Slice and serve chilled or at room temperature, optionally topped with whipped cream or fresh berries.

Optional: Serve with a sprinkle of sea salt for an added touch of flavor.
Exact quantities are listed in the recipe card below.

How to Store and Freeze Chocolate Hazelnut Tart

Fridge: Store your Chocolate Hazelnut Tart in an airtight container in the refrigerator for up to 3 days. Chilling allows the flavors to meld beautifully.

Freezer: Wrap individual slices in plastic wrap and place them in a freezer-safe container. The tart can be frozen for up to 2 months.

Thawing: To enjoy frozen slices, simply thaw them overnight in the fridge or at room temperature for about 30 minutes before serving.

Reheating: If desired, warm slices in the microwave for 10-15 seconds to slightly soften the ganache before serving for an extra indulgent treat.

Expert Tips for the Best Chocolate Hazelnut Tart

  • Room Temperature Ingredients: Make sure your butter and eggs are at room temperature to achieve a smoother ganache and better texture in your tart.
  • Careful Toasting: Watch the hazelnuts closely while toasting; burnt nuts can ruin the flavor. Stirring every few minutes ensures even toasting.
  • Chill for Flavor: Letting the tart chill for at least two hours enhances the flavors significantly—don’t skip this step for the best chocolate hazelnut tart experience.
  • Adjust Ganache Consistency: If you prefer a firmer ganache, slightly reduce the amount of heavy cream when making your filling—the balance is key!

What to Serve with Chocolate Hazelnut Tart?

There’s nothing quite like the magic of crafting a complete meal that complements the rich, sweet notes of a decadent dessert.

  • Fresh Whipped Cream: A dollop of airy whipped cream balances the tart’s richness while adding a light, creamy touch.
  • Vanilla Ice Cream: The cool, creamy ice cream melts beautifully against warm slices, bringing out the chocolate flavor even more.
  • Raspberry Coulis: Drizzling tangy raspberry coulis over each slice adds a pop of color and a refreshing contrast to the sweetness.
  • Espresso or Coffee: A rich cup of espresso enhances the chocolate, creating a delightful after-dinner experience for coffee lovers.
  • Chocolate-Covered Strawberries: The added fruitiness and crunch pair wonderfully with the chocolate ganache, creating a playful combination.
  • Toasted Almonds: Their crunch and nutty flavor echo the hazelnuts, making for a satisfying bite alongside the tart.

Each of these pairings not only elevate the flavors but also create a feast for both the eyes and the palate, ensuring your Chocolate Hazelnut Tart is the star of the show!

Make Ahead Options

These Chocolate Hazelnut Tarts are perfect for bustling holiday preparations! You can prepare the crust and ganache up to 3 days in advance, storing each component separately. To do this, bake the crust, let it cool completely, and wrap it tightly in plastic wrap before refrigerating. For the ganache, allow it to cool and then refrigerate it in an airtight container. When you’re ready to serve, simply reheat the ganache gently over low heat until smooth, assemble the tart with the toasted hazelnuts, and bake for about 20-25 minutes. This way, you’ll enjoy all the deliciousness of your tart with minimal effort on the big day!

Chocolate Hazelnut Tart Recipe FAQs

What type of hazelnuts should I use?
Absolutely! For the best flavor and texture, opt for whole, raw hazelnuts that you can toast yourself. This not only enhances their nuttiness but also gives you better control over the toasting process, ensuring they won’t burn. If you’re in a pinch, pre-toasted hazelnuts work just fine, but make sure they are fresh for optimal taste.

How should I store my Chocolate Hazelnut Tart?
Very important! Store your Chocolate Hazelnut Tart in an airtight container in the refrigerator for up to 3 days. Keeping it airtight helps the flavors meld beautifully. If you need to keep it longer, wrap individual slices in plastic wrap and place them in a freezer-safe container.

Can I freeze Chocolate Hazelnut Tart?
Of course! To freeze, wrap each slice tightly in plastic wrap and then place them in an airtight container. This tart can be frozen for up to 2 months. Just remember, when you’re ready to indulge, thaw the slices overnight in the fridge or leave them at room temperature for about 30 minutes before serving.

What should I do if my ganache is too runny?
If your ganache is too runny, don’t worry! You can address this by allowing it to set in the fridge for 15-30 minutes after making it. If needed, slightly reduce the heavy cream next time when making the ganache to achieve the firmness you desire. Also, ensure you’re using high-quality chocolate that contains a minimum of 70% cocoa for the best results.

Are there any dietary considerations for this recipe?
Absolutely! If you have allergies to nuts, you can substitute hazelnuts with other ingredients like almond flour or even omit them altogether for a nut-free version. Be mindful of using gluten-free flour if you’re catering to those with gluten sensitivities. Also, for a dairy-free option, substitute heavy cream with coconut cream and use dairy-free chocolate.

Can I make this tart ahead of time?
Definitely! This Chocolate Hazelnut Tart can be made up to three days in advance, which makes it a great option for holiday baking. Just ensure it’s stored in the refrigerator in an airtight container. In fact, many say the flavors deepen and improve after a day or two, so it’s a win-win for making ahead!
