Equipment

  • Roasting pan
  • Meat thermometer

Ingredients

We didn't put the cooking time above, because it really depends on your oven and size of your prime rib roast. Expect a total cooking time, of approximately 2-4 hours, for a prime rib of 6-10 pounds.

  • 8 lb prime rib, with ribs removed and tied back on ask your butcher to do this
  • 1/3 cup (80 mL) olive oil
  • 2 tbsp (30 ml) lemon juice
  • 3 tbsp dried or fresh rosemary leaves
  • 4 garlic cloves, minced
  • 1 tsp black pepper
  • 2 carrots peeled, and kept whole
  • 2 celery stalks kept whole
  • 1 yellow onion peeled and sliced in half

Instructions

  • Allow the roast to sit at room temperature for about 45 minutes. This will help it cook evenly.
  • During that time, prepare your rub by combining the olive oil, lemon juice, rosemary leaves, minced garlic and black pepper. We like to emulsify it using a hand mixer.
  • Preheat oven to 475 degrees F.
  • Line the middle of your roasting pan with the carrots, celery and onions.
  • Place your prime rib, with the ribs down, on top of the vegetables. Rub the meat with your marinade mixture. Pour some of the marinade down the opening between the ribs and meat. See picture above.
  • Place the roast in the preheated 475 degree F. oven for 20 minutes; this will sear the outside of the meat, and seal in the juices.
  • Reduce heat to 350 degrees F., and cook according to your preferences. See internal temperature chart above. We suggest 20 minutes per pound, for a medium roast and 15 minutes per pound for medium rare. Note that a meat thermometer is the only way to guarantee a perfect roast, just the way you like it.
  • To check the internal temperature of your roast, insert the thermometer in the thickest part of the meat. Avoiding touching fat or bone.
  • Remove the roast from the oven when the thermometer reads 5 degrees below your desired preference. Transfer the meat onto a cutting board and cover loosely with aluminum foil for 20-30 minutes. This is an important step as your meat will continue to cook and the juices will also remain in the meat.
  • Enjoy!
