In a bowl, combine all ingredients except for the pretzels. Whisk for a few minutes to combine.
Spread pretzels out on two rimmed baking sheets.
Pour oil/spice mixture evenly over pretzels. Use a spatula and stir the pretzels to coat.
Bake for 1 to 1-1/2 hours or until oil mixture is absorbed. Stir and turn trays approximately every 15 minutes. Remove from the oven and sprinkle additional nacho cheese powder over pretzels, stirring to combine.
Cool and store in airtight ziplock bags or containers until serving.
