Preheat oven to 300°F. Line a large baking sheet with parchment paper or aluminum foil and set aside.
Whisk the egg white and water together in a medium bowl until well combined. Add the pecans and stir until all of the pieces are coated.
In a separate 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 for 45 minutes, stirring the pecans every 15 minutes.
Remove from the oven and allow to cool completely on the baking sheet; breaking apart any pieces that are stuck together.
