Coat the lotus root in starch, drizzle oil in the air fryer, and cook at 200°C for 20 minutes.
Wash the lotus root thoroughly, peel, and slice thinly.
Soak in cold water for about 10 minutes to remove excess starch.
Add cooking oil to a pan and preheat.
Place lotus root slices in the pan and grill both sides over medium-low heat until golden brown.
Season with salt and pepper.
