How To Cook Frozen Air Fryer Pork Tenderloin

Since frozen meat is rock solid, it’s important to measure your frozen meat to ensure the pork tenderloin will fit.

1. Place the frozen pork tenderloin in a cold air fryer.
2. Turn your air fryer to 330 degrees and cook for 33-38 minutes, flipping it halfway until the pork reaches 160 degrees. If using the marinade above, baste the pork tenderloin on both sides halfway through cooking. I use this basting brush to evenly spread it on top.
