Measure walnuts into a dry skillet. Cook over medium heat.
1 cup walnut pieces
When you begin to smell the aroma of roasted nuts, stir the walnuts. Continue cooking until the nuts are toasted on all sides, about 5 minutes.
Turn the hot nuts out onto a plate to cool.
Toasting walnuts in the oven

Using toasted walnuts
Use the walnuts as is, or chop them into smaller pieces. Use a knife and a rocking motion on a cutting board to chop the nuts into the size you need for your recipe.
Notes
Adjust the amount of walnuts to suit your needs, using the skillet method for small amounts and the oven method for larger quantities.
Cool completely, then store toasted pecans in an airtight container for up to a month.
