1. Preheat your air fryer to 375°F. This ensures the cooking environment is ready for your chile rellenos, aiming for an evenly cooked, crispy texture.

2. Prepare the egg roll wrappers and cheese. Lay out the egg roll wrappers; place a slice of cheese inside each prepared chile before wrapping.

3. Wrap the chiles. Place a cheese-stuffed chile in the center of an egg roll wrapper. Fold the bottom corner over the chile, then fold in the sides and roll tightly. Use a little water to seal the final corner of the wrapper.

4. Spray with cooking oil. Lightly coat the wrapped chile rellenos with cooking spray. This helps achieve that golden, crispy exterior we’re aiming for.

5. Arrange in the air fryer. Place the chile rellenos in a single layer in the air fryer basket, ensuring they’re not touching to allow air circulation.

6. Cook for 10 minutes. Halfway through, gently flip the rellenos to ensure even cooking. The goal is a golden brown and crispy exterior, with the air fryer chile rellenos cooking time being key.

7. Check for doneness. They should be beautifully golden and crisp when done. Let them cool for a minute before serving.
