Place the sausages in the air fryer basket and cook until cooked through to an internal temperature of 165°F (74°C) in the center, 12 to 15 minutes, flipping halfway through. Transfer to a cutting board and slice the sausages lengthwise. Do not turn off the air fryer.☞ TESTER TIP: If you prefer more browning on your sausages, slice lengthwise before air frying. Note that the cook time will be reduced to about 10 minutes.
