In a large mixing bowl, combine all the ingredients and stir till everything is well combined.
Place the mixture into the basket of the air fryer. Turn the air fryer onto 400 for 50 minutes. Halfway through, stir the pepper mixture. Check on the potatoes around the 45-minute mark; once they can be pierced easily with a fork, they are done. Depending on your air fryer, you might need the full 50 minutes or slightly less.
