Gather all ingredients. Preheat the oven to 250 degrees F (120 degrees C).
Mix sugar, cinnamon, and salt together in a small bowl.
Whisk egg white and water together in a large bowl until frothy.
Toss pecans in the egg white mixture to coat.
Slowly pour in sugar mixture and stir until pecans are evenly coated.
Spread onto a baking sheet.
Bake in the preheated oven for 10 minutes. Stir pecans and rearrange into a single layer. Continue to cook, stirring every 10 to 15 minutes, until pecans are evenly browned, another 30 to 50 minutes.
Serve and enjoy!
