Slow Roasted Prime Rib Ingredients
To make this recipe, you will need a prime rib roast, olive oil, garlic, thyme, rosemary, kosher salt and black pepper.
How Do You Cook Prime Rib?
Cooking the perfect prime rib sounds intimidating, but with the right recipe it can be easy. Once you have selected your meat, let it rest on the counter for a half an hour. While the beef is resting, prepare it by tying it with twine between the ribs. This helps keep the meat together during the cooking process. Make a rub for the roast out of olive oil, garlic and seasonings. Generously coat the prime rib with the rub. Transfer the meat to a roasting pan. Place the roast in the oven and let it roast at high heat until the outside is browned. Lower the heat and continue to cook the meat. When it is done and the beef has reached your desired internal temperature, take it out of the hot oven. Once the meat rests for 20 minutes, serve the meat with any pan juices and enjoy!
How To Buy A Prime Rib
Prime rib is section of 7 beef ribs called standing rib roast or a bone-in rib roast. A full standing rib roast usually weighs about 17 pounds and is often cut into smaller sections. Each rib can serve 2 people, although you can serve a rib to each person for a larger meal or for presentation purposes. In order to determine how many ribs you need for your meal figure out how many people you will serve.
For the best quality of ribs, purchase your ribs from a butcher shop or a grocery store with a good butcher counter in a USDA “prime” or “choice” grade. You can ask for the bones of the roast to be “frenched”, which means your butcher will cut away the fat and meat at the ends of the ribs for a nicer presentation.
Tips For The Best Roast
- Some people remove the bones before cooking. I find that step unnecessary as the bone helps add to the flavor and moisture of the roast.
- If your prime rib roast comes straight out of the refrigerator it will tend to cook unevenly, so be sure to let it sit at room temperature first!.
- Remember to remove your meat about 5 degrees lower than the temperature you are aiming for. Cover the meat in aluminum foil and let it rest with the thermometer in place. The interior of the meat will continue to cook as it rests.
Quick Tip
Leftover slow roasted prime rib will stay fresh in the refrigerator in an airtight container for up to 3 days.
Slow Roasted Prime Rib Cooking Time
The amount of time that a prime rib takes to cook depends on the how done you want your meat. After an initial 15 minutes at 500 degrees F, you will cook the meat at 325 degrees F. The interior of the meat will reach a nice rare in about 10-11 minutes per pound at 325 degrees F. I cooked a 12 pound prime rib in 2 hours and 5 minutes. If you want a more done beef, add a few more minutes per pound. Remember that the time is only an estimate for planning purposes. You will want to cook your meat to the temperature corresponding to the doneness you want regardless of time.
Beef Temperatures
For a roast beef, you can determine the doneness based on the temperature of the inside of the meat. Make sure to remove the meat from the oven about 5 degrees below the temperature you are aiming for. Monitor the meat as it rests to make sure that it reaches your ideal temperature.
- Rare: 120-130 degrees F
- Medium Rare: 130-135 degrees F
- Medium: 135-140 degrees F
- Medium Well: 145-155 degrees F
- Well Done: 155 degrees F

Serves 10
Ingredients
- 12 pounds bone in prime rib roast 6 ribs
- 5 tablespoons olive oil
- 5 cloves garlic minced
- 4 teaspoons fresh thyme leaves minced
- 2 teaspoons fresh rosemary leaves minced
- 2 tablespoons salt
- 1 teaspoon pepper
Instructions
Preheat the oven to 500 degrees F.
Let your prime rib rest on the counter for 30 minutes. This allows the beef to cook more evenly.
While the prime rib is resting, tie it with twine between each rib. This holds the meat together as it roasts. Wrap the ends of the bones with foil to prevent them from burning.
Make a rub for the prime rib by mixing together the olive oil, garlic, thyme, rosemary, salt and pepper.
Generously coat the prime rib with the olive oil rub.
Place a meat thermometer in the center of the roast. Place the roast on a sheet pan or in a baking dish.
Cook your prime rib at 500 degrees F for 15 minutes to get a browned and flavorful exterior. Watch your roast, if the exterior starts to get too dark for your liking, lower the temperature of the oven to 325 degrees F.
After 15 minutes, reduce the temperature to 325 degrees F. Roast the meat until the thermometer reaches 5 degrees below your ideal temperature.
Remove the prime rib from the oven, cover it in foil and let it rest for 20 minutes.
Cut off the rib bones by holding the bones up vertically and cutting down between the bone and the meat.
Slice and serve the prime rib.
Notes
- Some people remove the bones before cooking, I find that step unnecessary as the meat gets well seasoned with the bone in and I find that the bone helps add to the flavor and moisture of the roast.
- If your prime rib roast comes straight out of the refrigerator it will tend to cook unevenly, so be sure to let it sit at room temperature before you put it in the oven.
