Preheat oven to 325°F. Prepare a large baking sheet with parchment paper and set aside.
In a large bowl, whisk together brown sugar, sugar, cinnamon and salt.
In a separate large bowl, combine pecans and egg white and toss until pecans are evenly coated.
Add sugar mixture to bowl with pecans and stir/toss to combine.
Pour pecan mixture onto prepared baking sheet and bake for about 25 minutes, stirring them after the first 15 minutes. Keep in mind everyone's oven it a little different, so you may need more or less time.
Remove from oven and let the pecans cool on the baking sheet until cooled. Transfer to an airtight container to store until ready to serve. Enjoy!
Can't or don't want to use egg whites? Substitute 3 tablespoons aquafaba.
Make sure you are using raw pecan halves, and not seasoned or salted ones.
Feel free to add other spices if you want to switch up the flavor - maybe a little nutmeg, ginger, or even a pinch of paprika.
