How to Cook Prime Rib

Ingredients

To make a juicy centerpiece worthy roast prime rib, you’ll need these simple ingredients:

  • One standing rib roast (see above for how many pounds to buy per person).
  • Salt, to taste
  • Pepper, to taste

Equipment

There are a few key pieces of kitchen equipment you’ll need to perfect your roast. Namely:

  • A roasting pan large enough to comfortably fit your standing rib roast, with sides.
  • A high-quality instant-read meat thermometer

Steps to Roast Prime Rib

Step 1: Prepare the Roast

If there’s a lot of visible fat on your roast, you may need to cut away excess fat. However, that fat is also key to building flavor and succulence in your roast, so don’t take off more than you think is necessary. in many cases, the rost has already been trimmed by your butcher before you bring it home, so you may not need to do any excess cutting.

Generally, you want to make sure that the prime rib is at room temperature before roasting. You can let it come to temperature for up to 3 hours before roasting. Place the meat on the roasting pan fat side up and sprinkle it liberally with salt. this will help tenderize the muscles and flavor the meat as it rests. be sure to keep the meat covered.

Step 2: Season the Roast

Towards the end of the resting time, preheat your oven. Start at 500°F. This is usually the highest a home oven will go, but if yours goes higher, crank it up to the highest temperature. Uncover the meat, and you’ll probably notice moisture on the surface from the salt. Pat the meat dry with paper towels.

At this stage, you can add any seasonings you’d like to add more flavor to your roast. Sprinkle the meat with dried or fresh herbs, spices, or flavoring pastes to your liking.

Popular spices for prime rib include cayenne, black pepper, garlic powder, onion powder, or adobo seasoning.

Step 3: Roast the Meat

Now your meat is ready to go into the hot oven. Roast the meat at 500°F for 15 minutes. This creates a nice brown crust on the fat side of the meat. It also renders the fat, which will drip down and infuse the rest of the roast with flavor as it cooks.

After the first 15 minutes at high heat, reduce the oven to 325°F. From here, you can finish cooking according to the size of your roast. the rule of thumb is to cook 11 minutes per pound for rare and 14 minutes per pound for medium-rare.  Of course, if your roast didn’t come up to temperature before roasting, a chilled cut of meat will take longer to cook the way through. the only way to know for sure that your roast is finished cooking is to consult your meat thermometer.

Step 4: Check for Doneness

When you’re halfway through your estimated cooking time, remove the roasting pan from the oven. Use a meat thermometer in the thickest part of the roast (avoiding any bone). If you find that the meat is cooking more quickly than you expected, reduce the oven temperature to 200°F and continue cooking.

Prime rib is done cooking when it registers 115°F for rare and 120 to 130°F for medium. Remember that the meat will continue to cook after it’s removed from the oven.

Step 5: Rest

Transfer the roast out of the roasting pan and onto a wooden cutting board. Cover it closely with aluminum foil and let it rest for 15 to 30 minutes. This allows the carryover cooking to finish cooking the roast and it ensures that the juices in the meat stay inside, rather than running all over your cutting board when you slice into it.

While the meat rests, you can make a quick gravy with the giblets and juices left in your roasting pan. In fact, you can cook the gravy directly in the roasting pan on your stove, no need to pour the contents into a saucepan. Start by adding broth to scrape up any browned bits on the bottom of the roasting pan. Stir the sauce over medium heat on the stove. Then thicken the gravy by adding a slurry. Mix 1 tablespoon of the hot liquid with 1 tablespoon all-purpose flour in a small bowl into a paste. Then stir this paste into the gravy, whisking until it’s thick. You can add a second slurry if the gravy isn’t thickened to your liking. Season the gravy to taste and reserve it, warm, to serve with your roast.

Step 6: Slice and Serve

After a full resting time, you can uncover the roast and slice it for service. First, cut away any butcher twine holding the roast together. Then slice the rack of ribs and remove the bones. Serve the slices of prime rib with your pan gravy.
