Toasting nuts takes just a few minutes and it greatly intensifies their flavor. You can toast them in the oven, the toaster oven, on the stove in a skillet or in the microwave oven. It is best to use nuts that are uniform in size. There's no need to oil the pan, but pay attention—nuts can go from perfectly toasted to charred in just moments.
Oven Toasting: Spread nuts in a single layer on a baking sheet. Cook at 400° for seven to 10 minutes until the nuts start to turn golden and begin to smell toasty; parts of some may still appear raw. Immediately remove them from the pan and place them on paper towels to cool.
Skillet Toasting: Place nuts in a single layer in a skillet over medium-high heat. Stir or shake them continually for five to seven minutes until they start to turn golden. Remove nuts from the pan as soon as they are done, and spread them on paper towels to cool.
Microwave: Spread nuts evenly in a flat microwavable dish. For half a cup of nuts, cook on high power for a total of three or four minutes, stirring three times during cooking. One cup of nuts should take about four or five minutes, depending on the oven and the size of the nuts. Microwave-toasted nuts will continue to darken after being removed from the oven. Cool on paper towels.
