Roasted Hazelnuts AKA Roasted Filberts

Whether we roast or toast hazelnuts to bake cakes, like this Hazelnut Butter Cake, or make Homemade Nutella, we essentially do that to bring out the nuts’ flavors and add some crunchy texture. Roasted hazelnuts have a darker color, deep and rich flavor, and crunchy pleasant texture. And they are great for baking these hazelnuts Shortbread Cookies, this Hazelnut Bread, and this epic Upside Down Hazlenut Cake.

Please remember that there is a big difference between roasting and toasting and talk more about the difference in my How to Toast pecans post.

Below are three ways you can roast or toast whole hazelnuts (whole filberts), the best way to know which works for you is to give each method a try.

Ingredients and Tools

Full measurement and instructions are at the bottom of this post, in the Roasted Hazelnut Recipe card

  • Raw Hazelnuts. You can use either chipped or whole, but for best results make sure not to mix the two sizes.
  • Oil. Such as coconut oil or olive oil, If you want to add flavors such as sea salt, cinnamon, cayenne pepper, or even oregano.

Tools:

  • Rimmed baking sheet, wide rimmed bowl, skillet and a wooden spoon.

How To Roast Or Toast Hazelnuts

Roasting Hazelnuts In The Oven (baking hazelnuts)

The traditional way and great for when you are not pressed on time and need to roast a large number of nuts, 1-4 cups.

Time needed: 15 minutes.

  1. Spread the nuts

    Spread the nuts in a single layer (no need for parchment paper) in a rimmed baking sheet. 

  2. Bake

    Bake in a preheated oven for 10-15 minutes stirring every 5 minutes.

Roasting Hazelnuts In The Microwave

This is by far the easiest and fastest way to roast these nuts, but it also limits us to small amounts, up to 1 cup.

  1. Spread the hazelnuts in a single layer in a wide-rimmed bowl lined with a paper towel.
  2. Cook for 6-8 minutes using 2 minutes increments, and swirl the bowl between each time.

Toasting Hazelnuts On The Stove

A great option when you are pressed with time and would like to toast a small number of nuts.

  • Spread the nuts in a wide skillet and cook over medium, or medium-low heat for 3-5 minutes while stirring.

How To Know The Nuts Are Ready

If you taste the nuts warm out of the oven, you will notice that they are chewy and they have yet to develop their rich deep flavor. So the best way to know if they are done is by first allowing your nose to guide you. When your kitchen is filled with a nutty aroma and, or when the nuts’ have golden brown skin, know that they are ready. Remove them from the heat and allow them to reach room temperature or remove the skin.

How to Remove Hazelnut’s Skin?

Many do not like the bitterness that the hazelnut skins add, personally, I like it so it is totally up to you whether to remove or keep the skin.

Pile the warm hazelnuts at the center of a clean kitchen towel and use your hand to rub the hazelnuts together and allow the loose skin to be removed. This step takes 3-5 minutes.

Storing 

Hazelnuts are rich in unsaturated fat which oxidizes and rancid pretty fast. Once the nuts have reached room temperature, place them in an airtight container. A mason jar or even a sealed plastic bag, are also good options. 

You can place them in a dry dark place in your pantry for about 4 weeks or in the freezer for up to 6 months.

Expert Tips

  • Chopped hazelnuts can be tricky as they roll over the place. Place the cutting board inside a 9×13 pan and chop.
  • If you need to finely ground nuts, consider using the food processor and adding 1 tablespoon of flour or powdered sugar to prevent the nuts from becoming too oily.
  • Your oven, microwave, and stove are different than mine. The time needed to roast or toast the nuts may vary. Pay close attention to their smell and color.

Recipe Notes

  • When warm, the nuts are chewy allowing them to reach room temperature before using and eating.
  • Use your sense of smell and sight to determine if the nuts are ready, when your kitchen is filled with a pleasant nutty aroma and the nuts are golden brown then they are ready.
  • Your oven, microwave, and stove are different than mine. The time needed to roast or toast the nuts may vary. Pay close attention to their smell and color.
