Season the prime rib: Generously coat the roast with 2 tablespoons of melted clarified butter or tallow, then sprinkle with salt.
Cook the prime rib: Place the roast in the air fryer basket and cook for 20-25 minutes, flipping halfway through. Cook until the internal temperature reaches 130°F for medium-rare, or adjust to your preferred doneness.
Baste with butter: During the last 5 minutes of cooking, baste the roast with the remaining tablespoon of butter or tallow for extra richness.
Rest and serve: Remove from the air fryer and let the roast rest for 5 minutes before slicing. Serve hot.
Notes
