Welcome to the world of Gelato, the Italian cousin to ice cream! Gelato is denser, creamier, and served slightly warmer than traditional ice cream, which allows its flavors to truly shine. This Chocolate Hazelnut Gelato (or Gianduia Gelato) is the ultimate expression of Italian dessert passion, blending rich cocoa with the distinct, nutty depth of toasted hazelnuts—the flavor pairing made famous by the Piedmont region of Italy.
This recipe uses a simple custard base to achieve that signature silky-smooth gelato texture. While it requires an ice cream machine and some chilling time, the process is straightforward, and the result is a scoop of pure, velvety decadence that tastes far superior to anything you can buy in a tub. It’s a sophisticated, creamy, and irresistible treat.

Ingredients
This recipe makes about 1 quart (approx. 4 cups) of authentic Italian-style gelato.
For the Hazelnut & Chocolate Base:
- ½ cup (about 70g) Raw Hazelnuts
- 1 ½ cups Whole Milk
- 1 cup Heavy Cream
- ¾ cup Granulated Sugar
- 4 Large Egg Yolks
- ¼ teaspoon Fine Sea Salt
- ½ cup (about 150g) Chocolate Hazelnut Spread (like Nutella, or homemade paste)
- 2 Tablespoons Unsweetened Cocoa Powder (Dark or Dutch-process preferred)
- 1 teaspoon Vanilla Extract
Step-by-Step Instructions
Part 1: Toast and Prep the Hazelnuts
- Roast: Preheat your oven to $350^\circ \text{F}$ ($175^\circ \text{C}$). Spread the hazelnuts in a single layer on a small baking sheet.
- Toast: Bake for about 10–12 minutes, stirring halfway, until the skins are shiny and the nuts smell fragrant.
- Peel: Immediately transfer the hot nuts to a clean kitchen towel. Fold the towel over them and rub vigorously for 1–2 minutes to remove most of the papery skins. Discard the skins. Roughly chop the peeled hazelnuts and set aside.
Part 2: Make the Gelato Custard Base
- Heat Milk/Cream: In a medium saucepan, combine the whole milk, heavy cream, and sugar. Heat over medium heat, stirring until the sugar is completely dissolved and the mixture is hot and steaming, but not boiling. Remove from heat.
- Temper the Yolks: In a separate medium bowl, whisk the egg yolks until they are pale yellow and slightly thickened. Slowly drizzle about $½$ cup of the hot milk mixture into the egg yolks while whisking constantly. This “tempers” the eggs and keeps them from scrambling.
- Cook the Custard: Pour the warmed yolk mixture back into the saucepan with the remaining milk mixture. Return to low heat and stir constantly with a rubber spatula. Cook until the mixture thickens enough to coat the back of a spoon (about 8–10 minutes). Do not let it boil!
- Strain and Mix: Immediately remove the saucepan from the heat. Pour the custard through a fine-mesh sieve into a clean bowl to remove any potential lumps.
- Add Flavor: Whisk in the chocolate hazelnut spread, cocoa powder, salt, and vanilla extract until everything is smooth and fully dissolved into the warm custard.
Part 3: Chill and Churn
- Chill: Cover the bowl with plastic wrap, pressing it directly onto the surface of the custard to prevent a “skin” from forming. Refrigerate until the base is thoroughly chilled—at least 4 hours, or ideally, overnight. The colder the base, the better the gelato texture.
- Churn: Pour the chilled gelato base into your ice cream maker and churn according to the manufacturer’s instructions (usually 20–30 minutes) until it reaches a soft-serve consistency.
- Add Crunch: In the last 5 minutes of churning, add about $¼$ cup of the reserved chopped, toasted hazelnuts.
- Harden: Transfer the gelato to an airtight, freezer-safe container. Top with the remaining chopped hazelnuts. Freeze for another 2–3 hours to firm up to the classic scoopable gelato texture.
Tips & Variations
- True Gelato Texture: Gelato is best served when slightly softer. Remove it from the freezer 5–10 minutes before serving.
- Nutella Shortcut: If you are pressed for time, you can skip toasting the nuts and simply use $¾$ cup of a high-quality chocolate hazelnut spread instead of $½$ cup of spread and 2 Tablespoons of cocoa powder. However, the toasted nuts add better depth of flavor!
- Vegan/Dairy-Free: Substitute the milk and cream with a combination of full-fat coconut milk (canned, chilled) and creamy plant-based milk (like oat or cashew). Replace the egg yolks with a cornstarch slurry (whisk 1 Tbsp cornstarch with 2 Tbsp cold water and stir into the warm milk before tempering the yolks).
- Hazelnut Puree: For an even more intense hazelnut flavor throughout, skip the chocolate spread and instead, blend the entire batch of toasted, peeled hazelnuts with the milk/cream mixture until a smooth, slightly grainy paste is formed, then strain the mixture before tempering the eggs.

Health Benefits
Gelato is an indulgent treat, but the ingredients still offer some benefits:
- Monounsaturated Fats: Hazelnuts are rich in monounsaturated fats (like oleic acid), which are known to support heart health and help lower LDL (“bad”) cholesterol.
- Vitamin E: Hazelnuts are an excellent source of Vitamin E, a powerful antioxidant that protects body tissues from damage.
- Minerals: Hazelnuts and cocoa powder are both good sources of Manganese, Copper, and Magnesium, which play roles in bone health and energy production.
- Lower Fat/Higher Milk Content: By definition, traditional gelato uses less cream and more milk than ice cream, and is churned slower to incorporate less air. This results in a slightly lower fat content by volume than many super-premium ice creams.
Serving Suggestions
- Classic Style: Serve in a small bowl or cup using a flat spade or spoon (not a round scoop) to create thin, ribbon-like layers.
- Drizzles: Top with a thin drizzle of high-quality dark chocolate ganache or a sprinkle of flaky sea salt.
- Affogato: Pair a small scoop with a shot of hot espresso for a classic Italian Affogato.
- Baking Pairing: Serve alongside a slice of almond cake, biscotti, or a warm fruit tart.
To Store Leftovers:
Store in an airtight container in the freezer. Gelato is best consumed within 1 week. Since it is served softer than ice cream, remove it from the freezer for 5–10 minutes before scooping to achieve its ideal, creamy texture.
