What Is Prime Rib?

The prime rib comes from the rib section of a steer’s anatomy, specifically ribs 6 through 12. It contains portions of the spinalis dorsi and longissimus dorsi muscles, some of the most tender and flavorful meat on the cow.

When purchasing prime rib, you can specify the exact number of ribs you want. The most common roasts contain either 3 or 4 ribs. If you want individual cut steaks instead of a whole roast, ask the butcher for ribeye steaks cut from the rib portion.

Opt for Prime grade for the highest marbling and tenderness or Choice grade for great flavor at a lower price point. Choose bone-in or boneless, depending on your cooking method and carving abilities. Bone-in primes ribs are also called standing rib roasts.

How Much Prime Rib per Person?

The standard recommended portion size for prime rib at restaurants or catered events is 10 to 14 ounces per person. However, when served family style or with generous side dishes, 8 ounces may suffice. Here are some general prime rib portion guidelines:

  • For a hearty appetite, allow 12-14 ounces per person.
  • For an average appetite or with sides, allow 8-10 ounces per person.
  • When budget is a concern, allow 6-8 ounces per person.
  • With a bone-in roast, allow 16-20 ounces per person to account for the bone weight.

Take these per person estimates and multiply by your guest count. Then use your total poundage number to select a roast size from your butcher.

Always buy slightly more than your calculations suggest, especially for bone-in cuts. Having extra leftovers is better than not having enough. Leftover prime rib makes excellent sandwiches or breakfast hash.

Choosing Your Prime Rib Roast

Choosing Your Prime Rib Roast

For the most even cooking results, choose a roast with an even thickness throughout the length. Estimate about 1/2 to 1 pound per rib bone. A 3-rib roast feeds 6 to 9 people and a 4-rib feeds 8 to 12 people comfortably.

A bone-in prime rib has a dramatic presentation and imparts extra flavor, but requires more skill to carve. The bones make up about 30% of the total weight. Opt for boneless if carving is a concern.

A boneless prime rib simplifies cooking, carving, and portioning. Have the butcher tie it for a uniform shape. Estimate about 1 pound per person.

Prime Rib Cooking Guide

Use these temperature guidelines as a starting point for your roast size:

  • For rare, cook to an internal temperature of 120°F (49°C).
  • For medium-rare, cook to an internal temperature of 125-130°F (52-54°C).
  • For medium, cook to an internal temperature of 135-140°F (57-60°C).

The meat will continue cooking and rise about 5°F after removed from the oven. Always let rest 15-30 minutes before carving.

Use an instant-read thermometer to check doneness in multiple spots. Oven temperatures between 250-325°F are ideal. With bone-in roasts, calculate 15-20 minutes per pound; boneless roasts cook faster at around 13 minutes per pound.

Preparing and Cooking Prime Rib

Follow these steps for roast prime rib worth bragging about:

Let It Come Up to Temp

  • Take the roast out of the fridge and let sit at room temperature for 1-2 hours before cooking. This helps it cook more evenly.

Make and Apply a Rub

  • Create a rub using coarse salt, cracked black pepper and dried herbs like rosemary, thyme, and/or oregano.
  • Generously coat all surfaces of the roast at least 40 minutes prior to cooking. The rub adds a tasty, textured crust.

Sear the Meat

  • Preheat your oven as high as it will go, ideally 500°F+.
  • In a large oven-safe skillet, sear all sides of the roast over high heat on the stovetop. This helps lock in juices.

Roast Low and Slow

  • Place the prime rib in a roasting pan, fatty side up.
  • Cook in the hot oven for 15 minutes to brown the outside.
  • Turn the oven down to 250-325°F to finish cooking over 2-4 hours until the desired internal temperature.

Rest and Carve

  • Allow the roast to rest tented in foil for 15-30 minutes before slicing to allow juices to redistibute.
  • Use a sharp knife to carefully cut against the grain into thick or thin slices.

Prime Rib Perfection Tips

  • Mind the temperature – Invest in a good digital meat thermometer for perfect doneness every time.
  • Watch the clock – For bone-in roasts over 10 pounds, extend cooking time to 20 minutes per pound.
  • Cut across the grain – Slicing across the natural grain of the meat ensures the most tender mouthfeel.
  • Make pan drippings gravy – Drippings from the rested roast make a flavorful sauce or au jus for serving.

Additional Considerations

Additional Considerations
  • Herb rub ingredients – Make a simple rub with 1 tablespoon each dried rosemary, thyme, black pepper, and coarse salt.Adjust herbs to your taste.
  • Equipment needed – Oven-safe roasting pan, instant read thermometer, basting brush or spoon, cutting board, sharp carving knife.
  • Alternate cooking methods – Prime rib tastes amazing cooked in a smoker, grill, or sous vide as well. Adjust times and temps.
  • Wine pairing – Cabernet Sauvignon, Zinfandel, and Syrah compliment the rich unctuousness of prime rib.
  • Side dishes – Classic pairings include au gratin potatoes, creamed spinach, roasted vegetables, and Yorkshire pudding.
  • Leftovers – Sliced cold prime rib makes amazing sandwiches. Reheat gently in au jus or broth to serve again hot.
  • Dietary restrictions – Substitute ingredients in the rub for food allergies. Skip the rub for Keto or Whole30.

      A pound per person is what I do and it’s what I told customers when I was a meat cutter; it’s always worked in my experience. You’ll have to account for shrinkage and whatnot when it cooks. If you think a 5 lb roast is still too much then go with 3.5 or 4 lb. …but prime rib sandwiches with buttered rolls are always my favorite the day after.

      I think your cook time was way short. I cook my Prime rib at 133f/56c for 16-24hrs, after a 24hr dry brine.
