🥣 How to Make Roasted Hazelnuts

Roasting hazelnuts is straightforward, and you can choose from several methods depending on your kitchen setup. Here’s how to do it:

If you’re seasoning the hazelnuts, go ahead and mix them with your oil or melted butter and seasonings first in a mixing bowl, making sure they are coated evenly.

In the Air Fryer

Start by preheating your air fryer to 300°F (150°C). Place the hazelnuts in a single layer in the basket, ensuring they’re not overcrowded. Air fry for about 12 minutes, giving them a stir halfway through to ensure even toasting. Let them cool before peeling off the skins.

On the Stovetop

Heat a large skillet over medium-low heat. Add the hazelnuts and toast them for 6-8 minutes, shaking the pan or stirring occasionally to roast them evenly. Once they’ve turned golden and aromatic, remove from heat and allow to cool before peeling.

In the Oven

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper if using oil or seasonings. Spread the hazelnuts in a single layer and roast for about 13-15 minutes, stirring halfway through. Watch closely towards the end to avoid burning them. Cool them down before peeling the skins.

How to Peel the Skin

Note: If you’ve seasoned them, this will remove the seasoning so skip this step! Once they’re cool enough to handle, rub them between your fingers or in a paper towel to remove the skins. If some skins are stubborn, wrap the hazelnuts in a clean kitchen towel and let them sit for a couple of minutes—the steam helps loosen the skins, making them easier to peel. Don’t worry if a few bits remain; they’re harmless and won’t affect the taste!

🪄 Recipe Notes & Tips

  • Watch the Heat: Hazelnuts can go from perfectly roasted to burnt quickly. Keep a close eye, especially in the final minutes.
  • Flavoring: If using oil and seasonings, coat the nuts evenly before roasting to maximize flavor absorption.

❓ Frequently Asked Questions

What’s the best way to check if hazelnuts are fully roasted?

Look for a golden-brown color and a nutty aroma. You can also taste one to ensure it’s crunchy through the center.

Do I need to add oil when roasting hazelnuts?

No, adding oil is optional. Roasting them dry is perfectly fine and brings out their natural flavors.

How do I know when the hazelnuts are starting to burn?

Ingredients
  

  • 200 g raw hazelnuts 1.5 cups
  • 1 tablespoon oil or butter optional, for seasoning
  • seasoning optional, see notes for ideas

Instructions
 

  • If you’re using oil, butter or seasonings, begin by coating the hazelnuts with the oil or butter in a mixing bowl, and then coating them with seasoning.

Roasting Hazelnuts in the Air Fryer:

  • Preheat your air fryer to 300°F/150°C
  • When the air fryer is ready, add the hazelnuts in a single layer to the air fryer basket, and air fry for 12 minutes.
  • Halfway through the cooking time, stir the hazelnuts and check how toasted they are. Adjust the remaining time by reducing it if needed.
  • Allow your roasted hazelnuts to cool before peeling them.

Roasting Hazelnuts in a Pan:

  • Heat a large skillet over medium-low heat.
  • When the pan is hot, add the hazelnuts to the skillet and roast them for 6-8 minutes, stirring occasionally.
  • Allow them to cool a little before peeling.

Roasting Hazelnuts in the Oven:

  • Preheat the oven to 350°F/175°C.
  • Spread the hazelnuts out on a baking sheet. You can line it with parchment paper for easy cleaning if you’re using oil or seasonings.
  • Roast the hazelnuts in the oven for 13-15 minutes, stirring and checking halfway through.
  • Adjust the time as needed, adding or reducing by a minute or two depending on how roasted they look halfway through.

How to Remove Roasted Hazelnut Skins:

  • Note: If you've seasoned them, this will remove the seasoning so skip this step!
  • Once the hazelnuts have cooled to touch, rub them between your fingers to remove the skins, or rub them with a paper towel.
  • Some skins may be a bit stubborn to remove. If I’m struggling with one I just let it be and move on.
  • You can also wrap them in a kitchen towel and let them sit for a minute or two before rubbing them in the towel. They seem to loosen easier with the steam created in the towel.

Notes

    • Watch the Heat: Hazelnuts can go from perfectly roasted to burnt quickly. Keep a close eye, especially in the final minutes.
