Begin by rinsing the radishes thoroughly under cold water, ensuring they are free of dirt. Pat them dry with a clean kitchen towel. For even cooking, slice the radishes into thin, uniform rounds, about 1/8 inch thick.

Place the radish slices in a large mixing bowl and drizzle with 3-4 pumps of avocado or olive oil. Toss them gently to ensure each slice is evenly coated. Sprinkle salt, pepper, garlic powder, and onion powder over the radishes, adjusting the seasoning to your taste.

Lay the seasoned radish slices in a single layer within the air fryer basket. Set your air fryer to 370°F and cook the radish slices for 5 minutes.

After the initial 5 minutes, open the air fryer and give the radish chips a gentle stir. Return the basket and continue cooking for another 5 minutes.

After a total of 10 minutes, check the radish chips for crispness. If they need a little more time, spritz with oil once more and sprinkle additional seasoning as desired. Cook for another 3 minutes.

Once golden brown and crispy, carefully remove the radish chips from the air fryer and let them cool on a plate.
