Yes, you can toast bread in air fryers and even make a toasted sandwich. You won't need an extra sandwich maker if you follow this process. All you have to do is put the bread slices in it. To get more crispiness, set it at a lower temperature and check on it often. Play with the temperature along with the type of bed for a while before you get the perfect texture that you are going to love. Bagels can also be toasted with the help of an air fryer.
