Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Spread 1 pound of pecan halves on the baking sheet in a single layer.
In a medium bowl, whisk together 1 large egg white and 1 tablespoon of water until frothy and slightly thickened.
Add the pecan halves to the egg white mixture and toss until the pecans are evenly coated.
In a separate bowl, mix together 3/4 cup of sugar, 2 teaspoons of ground cinnamon, and 1/2 teaspoon of salt.
Sprinkle the cinnamon-sugar mixture over the pecans and toss to coat evenly. Make sure all the pecans are well-covered with the sweet and spiced coating.
Spread the coated pecans back on the baking sheet in a single layer. Bake in the preheated oven for about 25-30 minutes, stirring halfway through to ensure even baking.
Once golden and crispy, remove the pecans from the oven and let them cool on the baking sheet. Store in an airtight container once cooled, and enjoy your homemade Buc-ee’s-style candied pecans!
