Preheat your oven to 300°F (150°C) if you're using the oven method. If using the stovetop, prepare a large skillet over medium heat.
In a mixing bowl, combine the sugar, cinnamon, and salt. If using an egg white, whisk it in a separate bowl until frothy and then add the vanilla extract. Combine the egg white mixture with the sugar mixture until well blended.
Add the raw pecans to the sugar mixture, guaranteeing they're fully coated. If using butter, melt it and stir it into the mixture before adding the pecans.
If using the oven method, spread the coated pecans in a single layer on a baking sheet lined with parchment paper. Bake for 30-45 minutes, stirring every 10-15 minutes to guarantee even cooking.
For the stovetop method, pour the coated pecans into the heated skillet and cook for about 5 minutes, stirring frequently until they're golden and fragrant.
Once cooked, remove the pecans from the heat and let them cool completely on the baking sheet or in the skillet. The coating will harden as they cool.
For the best results, remember to store your candied pecans in an airtight container at room temperature to maintain their crunch. They can last several weeks without refrigeration, making them a perfect make-ahead snack.
