Place the frozen uncooked Italian sausages in the air fryer. If they're stuck together, that's totally fine.
The total cooking time will be between 11-13 minutes. Check them after the first 2 minutes of cooking time to separate any sausages that are stuck together.
After a total of 6 minutes of cooking, turn them over and continue cooking the Italian sausage 5-7 more minutes until they are browned and cooked through to at least 160 F..
