Wash and peel the potatoes. Using a sharp knife cut them into uniform ¼-inch thick slices. Aim for slices that are the same width for even cooking.
Place the potato rounds in a bowl of cold water to soak for about 10 minutes. This will help remove excess starch for a crispier result. Drain the slices and pat them dry thoroughly with a paper towel.
Preheat your air fryer to 400°F (204°C) for 3-5 minutes. Preheating ensures that the air fryer is hot and ready for cooking.
In a large mixing bowl, toss the dried potato slices with 3 tablespoons of extra virgin olive oil, garlic powder, onion powder, smoked paprika, Italian seasoning, salt, and pepper until the thin slices are evenly coated.
Lightly brush the air fryer basket with a little oil or cooking spray to prevent sticking.
Arrange the seasoned sliced potatoes in a single layer in the air fryer basket, ensuring they are not overlapping. You might need to cook the potatoes in batches depending on the size of your air fryer. Air fry at 385°F (195°C) for 10-12 minutes, flipping the slices halfway through cooking.
Cook until the air fryer sliced potatoes are golden brown, crispy on the outside, and tender on the inside. Adjust cooking time as needed based on the thickness of the slices and your air fryer model. Thicker slices will need longer cooking times, while thinner slices may cook faster.
Once cooked, transfer the air fry potato slices to a serving platter and garnish it with grated cheddar cheese, chopped parsley, or a sliced green onion. Serve immediately with a side of pork chops, sour cream, or your favorite dip.
