  • 2 large russet potatoes
  • kosher salt to taste
  • cooking oil spray I use olive oil
  • 1 1/2 tablespoons buttermilk powder
  • 1 tablespoon onion powder
  • 1 teaspoon chives (dried)


  • Wash and scrub the potatoes. Use a mandolin and cut the potatoes into small slices about 1/10 of an inch thick.
  • Add the sliced potatoes to a bowl of cold water. Allow the potatoes to soak for at least 30 minutes. This will remove the excess starch from the potatoes and produce light and crunchy chips.
  • Remove the potatoes from the water and dry them thoroughly. This is an important step.
  • Spray the air fryer basket with cooking oil.
  • Sprinkle the potato slices with salt and add them to the air fryer. It's ok to stack the potatoes, but do not overcrowd the air fryer basket. Spray the potatoes with cooking oil.
  • Cook the potatoes on 400 degrees for 8 minutes. 
  • Open the air fryer and shake the potatoes. Cook for an additional 7 minutes or until the potatoes are golden brown in the middle and brown along the edges. and have formed chips. Cook time will vary based on the air fryer brand you use. Insert your judgment.
  • Add the buttermilk powder, onion powder, and chives to a food processor or blender. Blender for 20-30 seconds.
  • Remove the chips from the air fryer and toss them in the bowl with the seasonings.
  • Allow the chips to cool for 30 minutes. I lined a sheet pan with parchment paper. The chips will become more crunchy as they cool. 



If you don't use the buttermilk powder in this recipe, you will still have chips, they just won't taste as good as these are!
Be sure to dry the potatoes completely this will help the chips to crunch.
Spray both sides of the potatoes with cooking oil for crunchy chips.
Be sure to blend or process the seasonings. If you don't the mixture will curdle. 
The chips will get crisper upon standing.
