To roast pecans, toss the nuts with melted butter and spread on a pan or baking sheet. Add the desired seasonings and bake as directed by the recipe. Most recipes recommend roasting the pecans at 325 degrees Fahrenheit for 15 to 25 minutes.
Popular spices in roasted pecans include salt, sugar, corn syrup and cinnamon. Some roasted pecan recipes call for egg whites, while other recipes use cooking spray in place of the melted butter. A variant on the most common recipe recommends roasting the pecans more slowly, using a 225 or 250 degree Fahrenheit oven and cooking them for one hour. Recipes that utilize the one-hour cooking time recommend stirring the pecans every 15 minutes.
After removing them from the oven, allow the pecans to cool on a baking sheet for at least 15 minutes. Roasted pecans should be stored in an airtight container if not served immediately after cooling. They keep for up to two weeks when stored appropriately.
In addition to being eaten as a snack, roasted pecans are an essential ingredient in pecan pie. Roasting the pecans prior to using them in a pie preserves their optimum flavor and texture, protecting the pecans from becoming chewy.
