Apple crumble is an essential classic dessert. By adding hazelnuts, you give it a unique crunchy touch that makes all the difference. Simple, comforting, and quick to prepare.

Ingredients

Serves : 4 servings

  • 4 apples
  • 2 tbsp brown sugar (filling)
  • 20 g butter (filling)
  • 1 tsp cinnamon
  • 1 pinch salt (filling)
  • 1 tbsp lemon juice
  • 80 g unsalted butter (crumble)
  • 100 g all-purpose flour
  • 50 g hazelnut meal (ground hazelnuts)
  • 50 g crushed hazelnuts (lightly toasted)
  • 50 g brown sugar (crumble)
  • 1 pinch salt (crumble)

Instructions

Step 1

Peel the apples and cut them into chunks.

Step 2

In a skillet, melt the butter over low heat and add the honey. Let it caramelize slightly.

Step 3

Add the apple chunks, cinnamon, and a pinch of salt. Sauté for 5 minutes, stirring to coat the apples well.

Step 4

Deglaze with the lemon juice and let cool slightly.

Step 5

Melt the butter in a saucepan until it becomes "beurre noisette" (lightly golden brown and fragrant with a nutty aroma). Let it cool to lukewarm.

Step 6

In a large bowl, mix the flour, hazelnut meal, crushed hazelnuts, and brown sugar.

Step 7

Add the brown butter and mix with your fingertips until you reach a sandy, crumbly texture.

Step 8

Add a pinch of fleur de sel to enhance the flavors.

Step 9

Preheat the oven to 180°C (350°F). Spread the apples into a baking dish.

Step 10

Crumble the topping over the apples without pressing down too much to keep the texture light and airy.

Step 11

Bake for 25 to 30 minutes, until the crumble is golden brown. 👨‍🍳

Tips

  • Serve with a scoop of vanilla or salted caramel ice cream for an irresistible hot-and-cold contrast.
  • Toast your hazelnuts at home in a pan for a few minutes to boost their aroma.
  • Do not pack the crumble dough onto the apples to maintain maximum lightness.

Substitutions

  • butter → plant-based margarine or solid coconut oil — For a dairy-free version.
  • hazelnuts → almonds or pecans — To vary the flavors.

Frequently asked questions

Can I replace the hazelnuts with another type of nut?

Yes, you can replace them with almonds, pecans, or classic walnuts. Each will provide a crunchy texture and a slightly different flavor.

What type of apples should I choose for a crumble?

Golden Delicious, Braeburn, or Boskoop apples are ideal because they become melt-in-your-mouth tender during cooking while still holding their shape slightly.

Should I toast the hazelnuts before adding them?

It is not mandatory, but roasting them for a few minutes in the oven or in a pan intensifies their flavor and adds even more crunch.

Can I prepare the crumble in advance?

Yes, you can prepare the crumble topping and keep it in the refrigerator for up to 24 hours or in the freezer for a month. Assemble and bake at the last minute for a perfectly crispy crumble.

Can I replace the butter with a plant-based alternative?

Yes, you can use plant-based margarine or solid coconut oil for a dairy-free version.
