One well-reviewed recipe for sweet roasted pecans is Jerry's sugared pecans featured by Trisha Yearwood on "Trisha's Southern Kitchen." The recipe uses pecan halves, butter, egg whites, sugar and cinnamon.
To prepare this sweet roasted pecans recipe, preheat the oven to 350 degrees Fahrenheit, and pour 1/2 cup melted butter onto an aluminum foil-lined baking sheet. Combine 3 large egg whites, 1 cup sugar and 1 teaspoon ground cinnamon together in a large bowl. Add 4 cups pecan halves, and toss to coat. After spreading the pecans across the baking sheet, place them in the oven, and bake them for 30 minutes, stirring once every 10 minutes. Keep a close eye on the pecans near the end of the baking time to ensure they don't burn, reducing the heat if necessary.
Remove the baking sheet from the oven, letting the pecans cool for 10 to 15 minutes before transferring them to a container or bowl. Place the pecans in decorative jars or plastic bags tied with ribbons to give as gifts or party favors, or place them in a bowl as an appetizer for holiday parties or company get-togethers. For a flavor variation, use brown sugar in place of white sugar or add a dash of cayenne pepper.
