How to Cook a 5-lb. Prime Rib

A 5 lb. prime rib roast feeds about five people.

The prime rib roast is a cut of beef that comes from the rib section of the cow. It is also known as a "standing rib roast" and is one of eight cuts of beef considered "primal." A prime rib roast is tender and flavorful, traditionally prepared by seasoning the outside with a rub of salt, pepper and spices and slow roasting over dry heat. A 5 lb. prime rib roast serves approximately five people.

Things You'll Need

• 5 lb. prime rib roast, trimmed.
• Salt
• Pepper
• Garlic powder
• Meat thermometer

Instructions

1. Start by purchasing a high-grade roast from your butcher. You may elect to have some of the outer fat trimmed slightly, but be careful not to allow too much fat to be removed---this is what gives prime rib the distinct texture and flavor it is prized for. A good roast will have a degree of marbling and a thin layer of fat on one side.

2. Let the roast come to room temperature. Rub the outside of the roast with the salt, garlic and pepper.

3. Preheat the oven to 450 degrees or gas mark 8.

4. Place the meat in a roasting pan, fat side up. Roast at this temperature for 30 minutes to sear the outside.

5. Reduce heat to 325 degrees or gas mark 3. Roast for 1 hour, then test with the meat thermometer. Continue roasting until the internal temperature reaches 125 to 130 degrees for rare to medium rare, 135 to 140 degrees for medium.

6. Remove the roast from the oven and cover it with aluminum foil for 15 minutes to rest before carving. Allowing the meat to rest gives time for the juices to redistribute and allows for a much more tender result.

Tips & Warnings

• Choose a high-grade cut of beef and allow your butcher to trim some, but not all, of the outer layer of fat. You can also have them tie the roast for easier cooking.

• Allow your meat to rest before carving.
