Walk into any high-end steakhouse and you’ll see both on the menu. One is usually priced by the ounce and wheeled out on a silver cart. The other is sizzling on a cast-iron plate, charred to perfection. It’s confusing. People use the terms interchangeably all the time, but if you’re dropping $60 on a dinner, you should probably know what you’re actually ordering. So, is prime rib a ribeye steak?
The short answer is: sort of. They come from the exact same part of the cow. However, calling them the same thing is like saying a block of marble is the same thing as a finished statue. The difference lies in how they are butchered, how they are cooked, and—most importantly—how they feel when you finally take a bite.
Where the Meat Actually Comes From
Both of these legendary cuts originate from the primal rib section of the beef cattle. This area spans from rib six through rib twelve. Because this muscle group doesn't do a lot of heavy lifting (unlike the shoulder or the leg), the meat stays incredibly tender. It’s also where you find that beautiful intramuscular fat, also known as marbling, which gives the beef its flavor.
When a butcher leaves the entire seven-rib section intact, you have a standing rib roast. That is prime rib. It’s a massive hunk of meat. If the butcher decides to slice that roast into individual steaks before cooking, those slices become ribeye steaks. It’s a matter of timing and geometry.
Think about it this way. Prime rib is cooked as a giant roast, usually bone-in, and then sliced into portions after it’s done. A ribeye is sliced thin (relatively speaking) while the meat is still raw and then hit with high heat to create a crust.
The Cooking Method Changes Everything
This is where the two paths diverge. You can’t cook a prime rib the same way you cook a ribeye. Well, you could, but you’d have a very expensive disaster on your hands.

Prime rib is almost always roasted slowly. Low and slow is the name of the game here. Chefs usually rub the outside with salt, pepper, garlic, and maybe some rosemary or thyme. It sits in the oven for hours until the internal temperature reaches a perfect medium-rare. Because it's cooked as a whole unit, the meat stays exceptionally juicy. It’s often served with au jus (the natural juices) and horseradish cream. The texture is more like a "roast"—it’s soft, uniform, and pink from edge to edge.
Ribeye steak, on the other hand, is built for the grill or a screaming-hot skillet. You want that Maillard reaction. That’s the chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor. When you sear a ribeye, you get a salty, crunchy crust that contrasts with the fatty interior. It’s a faster, more aggressive way to cook.
Decoding the Prime Label
Here is a point where a lot of people get tripped up. The word "prime" in prime rib doesn't necessarily refer to the USDA grade. This is a weird quirk of the meat industry.
The USDA grades beef as Prime, Choice, or Select based on marbling and the age of the animal. You can actually buy a "Prime Rib" roast that is technically graded as "Choice." It’s a naming convention for the cut, not always a reflection of the quality tier. However, if you see a "Prime Ribeye," that specifically means the steak has achieved the highest USDA grade for marbling.
Honestly, it’s a bit of a marketing trap. Always look at the marbling yourself. If the meat is streaked with thin white lines of fat, it’s going to taste good regardless of the specific name on the sticker.

Texture and Flavor Profiles
When you eat a ribeye, you’re looking for that fat to be rendered. Because it’s cooked at high heat, the fat pockets (specifically the "deckle" or spinalis dorsi) melt into the meat. It’s smoky. It’s charred. It’s intense.
Prime rib is more subtle. Since it’s roasted at a lower temperature, the fat doesn't always fully "melt" in the same way. Instead, it becomes soft and buttery. You get more of the pure, unadulterated beef flavor without the smoky interference of a grill. Some people find the texture of prime rib too "soft," while others find ribeye too "tough" in comparison.
One more thing: the bone. Prime rib is almost always cooked bone-in, which many enthusiasts argue adds a deeper flavor to the meat near the ribs. Ribeyes can be bone-in (often called a cowboy cut or tomahawk) or boneless.
Why the Price Varies
You’ll notice that is prime rib a ribeye steak becomes a very relevant question when you look at your bill. Usually, prime rib is more expensive per serving at a restaurant. Why? Because it’s harder to manage.
A chef has to commit to cooking a whole roast hours before a customer walks in. If they cook three massive roasts and only ten people order prime rib, that’s a lot of wasted, high-end meat. Ribeyes are easier for a kitchen to manage because they stay raw in the fridge until someone orders one. You’re paying for the labor, the time, and the "limited availability" of the roast.

Choosing the Right One for the Occasion
If you’re hosting a Christmas dinner or a big anniversary party, the prime rib is the showstopper. It looks incredible on a platter. It feels like a celebration.
If it’s a Tuesday night and you have a craving for beef, or if you’re at a steakhouse and want that classic "steak" experience, the ribeye wins every time. It’s more customizable. You can get it rare, medium, or (heaven forbid) well-done, and it will still have that characteristic sear.
How to Buy Them Like a Pro
When you go to the butcher, don't just ask for "meat." Be specific.
- For Prime Rib: Ask for a "standing rib roast." If you want the best part, ask for the "small end" (ribs 10-12). This area is closer to the loin and usually has less large chunks of fat and more usable meat.
- For Ribeye: Ask for a "center-cut ribeye" if you want a neat, round steak. If you want the most flavor, ask for a "ribeye cap" (the spinalis), though it's hard to find on its own because it's the most prized part of the whole cow.
Practical Steps for Home Cooks
If you are planning to cook these at home, keep these specific strategies in mind to avoid ruining an expensive piece of protein.
- Salt early. Whether it’s a roast or a steak, salt it at least 45 minutes before cooking—or even 24 hours before for a roast. This allows the salt to penetrate the fibers and actually season the meat, not just the surface.
- Use a thermometer. You cannot eyeball a prime rib. A $20 digital meat thermometer is the difference between a perfect dinner and a dry, gray mess. Pull a roast at 120°F (49°C) for a perfect medium-rare after it rests.
- The Resting Period. This is non-negotiable. A ribeye needs to rest for 5 to 10 minutes. A prime rib roast needs to rest for at least 20 to 30 minutes. If you cut it too soon, all the juice runs out onto the board and the meat becomes tough.
- The Reverse Sear. This is the "pro hack" for ribeye steaks. Cook the steak in a low oven (225°F or 107°C) until it reaches about 110°F (43°C), then take it out and sear it in a smoking-hot pan for 1 minute per side. This gives you the edge-to-edge pink of a prime rib with the crust of a steak.
Ultimately, the choice between them comes down to how you like your fat. If you want it rendered and crispy, go ribeye. If you want it soft and succulent, go prime rib. They are two different expressions of the best cut of beef on the animal. Use a heavy hand with the salt, never skip the rest period, and always slice against the grain for the best experience.
