Begin by thoroughly washing your russet or Yukon Gold potatoes under cool running water to remove any dirt. Slice the potatoes into about ¼-inch thick rounds using a sharp knife or mandoline.

In a mixing bowl, add the sliced potatoes and drizzle with olive oil, if desired. Sprinkle in salt, pepper, and optional seasonings. Toss the potato slices until evenly coated.

Preheat your air fryer to 400°F (200°C) for a few minutes to ensure it reaches the optimal cooking temperature.

Carefully place the seasoned potato slices in a single layer in the air fryer basket, avoiding any overlap.

Set your air fryer to cook for 15-20 minutes. Shake the basket halfway through for even cooking and browning.

Once browned and crispy, carefully remove the potatoes from the air fryer and serve immediately.
