Hazelnuts have a rich, buttery flavor that complements both sweet and savory dishes, but those hazelnut skins can be bitter.


Baking soda, or sodium bicarbonate, is key here. The alkalinity of baking soda helps break down pectin in the blanched hazelnut skins, making them super easy to remove.

Please see the recipe card below for complete information on ingredients and quantities.

Variations and substitutions

If you don’t have baking soda, the traditional method of skinning hazelnuts is by roasting. To roast hazelnuts, heat them in a 350 degree Fahrenheit oven for about 10 to 15 minutes until they smell toasty. Let the roasted hazelnuts cool slightly, then wrap them in a kitchen towel and rub them together vigorously. You’ll be able to remove much of the peel this way.

Recipe tips and tricks

Step 1: Create an ice bath by filling a large bowl with equal amounts of ice and cold water. Ice baths are great for quickly stopping the cooking process and preserving texture and color (e.g. for green vegetables).

Step 2: Fill a small pot halfway with water and bring it to a boil. Add the baking soda and hazelnuts and keep at a boil for about four to five minutes. Don’t be surprised when the water turns black!

Test a hazelnut at about four minutes by dropping it into the ice bath. If the peel doesn’t come off easily, keep blanching the hazelnuts for another minute and test again.

If the hazelnut peel comes off in a snap, drain the pot of blanched hazelnuts in a colander. Then immediately transfer the blanched hazelnuts to your ice bath.

Step 3: Peel any blanched hazelnuts that still have skin. You can do this one by one, or grab a handful and rub them together.

In one recipe test, I tried to see if I could toast the blanched hazelnuts and then rub the skins off in a towel to avoid peeling each hazelnut individually from the ice bath. This was unfortunately not effective!

Step 4: If you taste the blanched hazelnuts at this point, it will be a little soft and bland. To bring out their flavor, toast those hazelnuts in a hot oven until they smell, well, toasty. I always recommend toasting nuts, whether you’re using them in a walnut loaf cake or adding pine nuts to a couscous salad.

Roast the blanched hazelnuts for 15 to 20 minutes. Toasting will take longer than usual because the hazelnuts have been blanched, but there’s no need to dry them first.
