• Preheat the oven to 375 degrees F.
• Use a mandolin to slice up the potato. Lay potato slices on a baking pan.
• Spray the potato slices with no stick cooking spray, then sprinkle 1/2 of the ranch mix onto them. Flip over the potatoes and repeat on the other side.

For the oven:

• Bake for 10 minutes, then flip over the potatoes. Continue baking 10 minutes or until golden brown.
• Remove from oven and place potatoes on a cooling rack until cool.

For the air fryer:

• Add the potato slices to the air fryer basket in a single layer. (I had to do two batches.)
• Air fry at 350 degrees for 10 minutes, flipping halfway through.
