Why toast walnuts?

Toasting nuts tend to bring out their earthiness and lowers any bitterness to the maximum level found in raw nuts. In only a few minutes of toasting, nuts will alter their pale color, a bit waxy, and mild in smell and flavor.

The toasted walnuts will have a golden-brown color, rich taste, and delicious aroma and intensity. So, it adds an entirely new level of flavor to any dish.

The toasting of walnuts, on the other hand, improves the texture as well. They stay crispy whether on top of a salad or buried in baked foods.

Ways to toast walnuts

Here are the different methods to toast walnuts.

Air fryer

Nowadays, you can conveniently toast walnuts using advanced gadgets. If you have an air fryer, put the walnuts in a single layer at the bottom of the basket. Set the time count to 4 to 6 minutes and a temperature of 300 degrees. Just after a few minutes, get your toasted walnuts ready and enjoy.


While using a microwave, put the walnuts in a microwave dish in one layer. For two minutes, microwave on high and then stir. Later, cook the walnuts for one minute, stir nuts after every minute, and check for readiness. The cooking process can go long, from three minutes to about eight minutes, depending upon the type of walnuts you are toasting.


Using a stovetop to toast walnuts is an excellent choice to make when you toast a small amount. All you got to do is place the walnuts in a dry skillet, cook on medium flame and keep tossing them from time to time. It is a relatively quick method and helps to keep an eye on the entire process. After doing this, remove walnuts from the skillet and transfer them to a bowl to let them cool.


To toast chopped walnuts in an oven, put them on a baking sheet in one layer and place them in a preheated oven to 350 degrees. It takes about 5 to 10 minutes in the process to lightly toast the walnuts. Keep an eye on the walnuts and stir when needed. Then, take them out from the oven and put them in a bowl for cooling.

What is the easiest way to toast walnuts?

The stovetop method is the easiest and the best way for smaller amounts of nuts. As we know that walnut can cook unevenly if not appropriately stirred and tossed frequently. Additionally, be sure to put walnuts in a single layer, as too many nuts can lead to uneven cooking.

How to toast walnuts faster?

For a faster experience, you can use a microwave or an air fryer. Instead of transferring the nuts from the saucepan to a bowl, put them directly in the microwave. Cook at a high temperature for 1 minute and stir it after every minute. Toast walnuts until they are slightly browned but not burned.

How to toast unshelled walnuts?

Toasting unshelled walnuts are a bit more challenging than shelled ones. When they are in the shell, they are less exposed to heat, so it is harder for the nuts to get browned evenly and thoroughly. To make matters worse, it is more difficult to stir and toss them frequently when they are in the shell.
