Preheat the air fryer to 400F.
Remove the outer skin of the onion and cut in half. Cut into slices.
Place the onion in the baking dish with a pinch of salt and pepper, the brown sugar and the oil. Mix well to combine.
Cut the butter into slices and place on top of the onions.
Place in the air fryer for 8 minutes and stir halfway through.
Reduce the temperature to 360F and cook for 20 minutes, stirring every 5 minutes to help them cook evenly.

Make sure that the onion slices are well coated in the oil and seasonings. I like to use my hands to toss them so they are evenly covered.
Preheat the air fryer before adding the onions. If your air fryer doesn't have a preheat function, let it run for 400F before adding them in.
Give the onions a quick stir every 5 minutes. This will help them to cook evenly and not dry out. I like to set my air fryer in 5 minute intervals so that I get a warning when I need to stir.
Different air fryer models can vary in their speed of cooking, so times may vary.
