  • Dry the meat: Pat the rib roast dry on both sides with a paper towel. This will ensure that the mustard rub sticks, and that the outside will brown evenly. Too much moisture on the exterior will cause the meat to steam.
    4 lb Prime rib roast
  • Make the rub: In a bowl or measuring cup, mix together the ingredients for the mustard rub. Using a silicone pastry brush, spread a liberal coat of the rub on one side of the roast.
    ½ cup Dijon mustard, ½ cup Extra virgin olive oil, 3 cloves Garlic, 1 teaspoon Onion powder, 1 tablespoon Thyme, 1 tablespoon Sea salt, 1 tablespoon Black pepper
  • Transfer to the air fryer: Place the roast in the air fryer basket, rub side down. Evenly spread the other side of the roast with another liberal coat of the rub. If using, insert a probe thermometer into the thickest part of the meat.
  • Cook: Air fry at 375°F until a meat thermometer reads between 130-134°F for medium-rare prime rib. Remove from the air fryer, and transfer to a cutting board. Tent with foil, and let rest for 15-20 minutes before carving.



The following is a doneness chart, depending on the size of your prime rib and your desired doneness:
Rare 120-129°F (49-54°C)
Medium Rare 130-134°F (55-57°C)
Medium 135-144°F (58-62°C)
Medium Well 145-154°F (63-67°C)
Well Done 155-164°F (68-73°C)
Keep in mind that the temperature of your meat will rise up to 15° while resting!
