Start by peeling the lotus root carefully with a vegetable peeler, ensuring all the skin is removed. Slice the lotus root into 1/4-inch thick rounds and then rinse them under cold water to wash away any excess starch.

In a large mixing bowl, toss the sliced lotus root with a drizzle of olive oil, sprinkling salt, ground black pepper, garlic powder, and chili powder to your taste.

Set your air fryer to preheat at 375°F (190°C) for about 3-5 minutes.

Place the seasoned lotus root slices in a single layer in the air fryer basket and cook for 12-15 minutes, shaking the basket halfway through.

Once cooked, carefully remove the crispy lotus root from the air fryer and transfer them to a serving platter.
