Preheat the oven to 300°F (150°C). Line a large baking sheet with parchment paper and set aside.
Add the pecans to a large mixing bowl and set aside. Add the egg white and water to a separate bowl and whisk together until well combined and frothy. Pour the egg white mixture onto the pecans and stir until all of the pecans are fully coated.
In another bowl, whisk together the sugar, cinnamon, and salt. Pour the cinnamon sugar mixture over the pecans and stir until all of the pecans are fully coated.
Spread the pecans onto the prepared baking sheet in a single layer. Bake at 300°F (150°C) for 45 minutes, stirring the pecans every 15 minutes.
