Instructions
PREP THE BEEF
Take your beef joint out of the fridge for 30 minutes prior to cooking to allow it to come to room temperature. Pat dry and drizzle with olive oil then season liberally with salt and pepper, a good 10 turns of the mill per side. Sprinkle with the seasoning.
ROAST IN AIR FRYER
Preheat the air fryer ( I used my Cosori XXL) 400°F / 200°C for 10 minutes. Place the beef in the air fryer basket and cook for seven minutes per side (14 minutes total).
Reduce the temperature to 350°F / 180°C and cook for a further 15 minutes per side. Check the core temperature with an instant read thermometer inserting the probe in the middle thickest part. If the beef is not quite done then continue cooking for a few more minutes (3-5).
REST THE BEEF
Transfer the beef to a plate and cover loosely with foil. The temperature will continue to rise slightly as it rests – check my roasting time chart to ensure roasting perfection.
CARVE AND ENJOY
Rest for 20-30 minutes then slice against the grain and serve with your favorite side dishes, such as my Air Fryer Yorkshire Puddings and Perfect Roast Potatoes!
BEEF ROAST TEMPERATURE CHARTI suggest you cook prime rib rare or medium rare. Take the beef out of the air fryer when the temperature register about three degrees LOWER than the desired target temperature to allow for it to rise slightly as it rests.
