Cinnamon-Sugar Pumpkin Seeds

Preheat oven to 300 degrees F.

Spread pumpkin seeds in an even layer on a large rimmed baking sheet. Bake, stirring once, until lightly toasted, about 40 minutes.

Meanwhile, combine sugar, cinnamon and salt in a small bowl. Remove the pumpkin seeds from the oven and carefully transfer to a medium bowl. Pour egg white and butter over the seeds and stir to coat. Sprinkle the sugar mixture over the pumpkin seeds and stir to coat. Return to the baking sheet and spread in an even layer. Bake until lightly browned, 10 to 20 minutes. Cool completely before serving.
