Pecans are a nutritious and healthy snack chocked full of vitamin E, fiber, and heart-healthy omega-3 fatty acids. Roasting pecans with the shell on can be performed in the same manner as roasting peanuts and other nuts in the shell. Roasting nuts in the shell takes a little longer than roasting nuts without a shell but it will give the pecans a natural, rustic flavor.
Preheat your oven to 350 degrees Fahrenheit.
Coat the baking sheet lightly with cooking spray. Alternatively, you can toss the pecans in 3 tbsp of melted butter or coat them with 2 tbsp of cooking oil.
Spread the pecans evenly onto the baking sheet. Use as many pecans as will fit onto the baking sheet without staking on top of each other. You want an even layer of nuts on the baking sheet.
Bake the pecans for 15 to 20 minutes. Check them frequently so they do not burn.
Transfer the pecans from the baking sheet to a paper towel to cool. If the pecans are left on the baking sheet they will continue to brown and cook.
