What Is Prime Rib?
Prime rib, also known as a standing rib roast, is a premium cut of beef that comes from the primal rib section of the cow. This section runs along the back of the animal, specifically from ribs six through twelve. The meat here is well-marbled with fat, which gives it its signature tenderness and juicy flavor when cooked. Prime rib is often served as a roast, making it a centerpiece for celebrations and special occasions.
Where Does Prime Rib Come From?
The primal rib section is located between the chuck (shoulder) and the loin (back) of the cow. This area isn’t used as much for movement, so the muscles remain tender. When butchers prepare prime rib, they typically use ribs 6 through 12. The entire section can be roasted whole or cut into smaller portions, depending on how many people you’re serving.
Prime Rib vs. Ribeye: What’s the Difference?
It’s easy to get confused between prime rib and ribeye because both come from the same section of the cow. The key difference is in how they are prepared and served:
- Prime Rib: Usually roasted whole with the bone in and sliced to serve. It’s often cooked slowly to retain moisture and enhance flavor.
- Ribeye: Typically cut into individual steaks before cooking and grilled or pan-seared. Ribeye steaks can be bone-in or boneless.
Both cuts are flavorful and tender, but prime rib is often considered more luxurious due to its presentation and size.
Why Is It Called “Prime” Rib?
The term “prime” in prime rib can be a bit misleading. While “prime” refers to the highest USDA grade for beef (based on marbling and quality), not all prime rib roasts are actually USDA Prime grade. Many grocery stores sell “prime rib” that may be graded as Choice or Select. If you want true USDA Prime beef, you’ll need to ask your butcher specifically.
How to Buy Prime Rib
When shopping for prime rib, here are some tips to ensure you get the best cut:
- Grade: Look for USDA Prime for the best marbling and flavor, but USDA Choice is also excellent and more affordable.
- Bone-In vs. Boneless: Bone-in roasts tend to be juicier and more flavorful. The bones also help insulate the meat during roasting.
- Size: Plan on about one pound per person if you want generous servings.
- Trim: Ask your butcher to leave a layer of fat on top (called the fat cap) for extra flavor and moisture during cooking.
Preparing Prime Rib
Cooking prime rib doesn’t have to be intimidating! Here’s a simple overview of how to prepare this delicious roast:
- Bring to Room Temperature: Take your roast out of the fridge about an hour before cooking so it cooks evenly.
- Season Generously: Use plenty of salt, pepper, garlic, and herbs like rosemary or thyme. The seasoning forms a tasty crust during roasting.
- Roast: Place the meat bone-side down in a roasting pan. Start at a high temperature (around 450°F) for 20 minutes to sear the outside, then reduce heat (to around 325°F) and continue roasting until it reaches your desired doneness.
- Rest: Let the meat rest for at least 20 minutes after removing it from the oven. This helps redistribute juices for extra tenderness.
- Carve and Serve: Slice between the bones for generous portions and serve with your favorite sides.
Tips for Perfect Prime Rib
- Use a Meat Thermometer: This ensures you hit your preferred doneness without overcooking. Aim for 120°F for rare, 130°F for medium-rare, or 140°F for medium.
- Let It Rest: Don’t skip resting time! It keeps your roast juicy.
- Add Flavors: Try rubbing with garlic butter or adding fresh herbs for extra aroma.
- Save Leftovers: Leftover prime rib makes amazing sandwiches or can be added to soups and salads.
Serving Suggestions
Prime rib pairs beautifully with classic sides like mashed potatoes, roasted vegetables, Yorkshire pudding, horseradish sauce, or au jus (a savory beef broth sauce). For a show-stopping meal, serve it with a bold red wine like Cabernet Sauvignon or Merlot.
Frequently Asked Questions About Prime Rib

- You can buy individual ribeye steaks (from the same section), but prime rib is typically sold as a larger roast.
