Place frozen sausage patties or links in air fryer basket. Don't stack them on each other.
Cook at 400 degrees F for 5 minutes. Flip the sausage patties and cook another 3-4 minutes. You might want to add 2-3 extra minutes depending on how brown you like your sausage. Make sure the internal temperature reaches 160 degrees F.
Carefully remove and serve.

Notes
If you like your sausage extra crispy, add an extra 2-3 minutes cook time.
