Look no further than these two foolproof methods if you're wondering How to Toast Walnuts. It is so fast and simple to either cook them in a skillet or bake them in the oven.
Preheat oven to 350 °F.
Line a large, lightly colored baking sheet with parchment paper. Place walnuts in a single layer on the sheet.
Toast walnuts in preheated oven for 7-10 minutes, stirring occasionally. (A little less time if they are coarsely chopped prior to roasting.)
Heat a medium to large, non-stick dry skillet over medium-low heat. Add no more than 1 cup of walnuts to the skillet in a single layer.
Toast nuts for 3-5 minutes, stirring occasionally. (A little less time if they are coarsely chopped prior to toasting.)
