If your idea of the perfect meal involves a steak seared to perfection, then fire up the grill—and keep reading. We’re serving up all there is to know about prime rib versus ribeye steak, as well as the best cooking tips and recipes to make the most of these two flavorful beef cuts.
Here’s your primer on prime rib. Also known as a standing rib roast, this popular holiday cut comes from the same part of the cow as the ribeye: the rib section. A cow has 13 ribs per side, and butchers have a system of identifying each rib in ascending order from the front of the cow to the back [1].
Ribs in the 6 to 12 group are sold as prime rib, but just because the word “prime” is in the name doesn’t necessarily mean that it’s USDA Prime, which is the U.S. Department of Agriculture’s highest quality grade. The USDA Prime label indicates that the meat is heavily marbled with about 10 percent intramuscular fat (the white streaks that make every bite extra flavorful). The second highest beef grade is “Choice,” used for moderately marbled meat [2]. Be sure to check with your butcher before you buy!
Prime rib is prized for its tenderness and rich, beefy flavor, thanks to its higher fat content and marbling. It’s typically roasted bone-in, which not only enhances the flavor but also makes for a dramatic presentation—perfect for holidays or special occasions. The bones also help insulate the meat as it cooks, contributing to a juicy, evenly cooked roast.
When shopping for prime rib, you might also hear terms like “first cut” or “second cut.” The first cut (closer to the loin) is generally leaner and more uniform, while the second cut (closer to the chuck) has more connective tissue and fat, which adds flavor but can be a bit more rustic in texture. If you’re looking for a balance of tenderness and rich flavor, many chefs recommend opting for the second cut.
Preparing prime rib at home doesn’t have to be intimidating. A slow roast at a low temperature followed by a quick blast of high heat (a method known as reverse searing) helps achieve that ideal medium-rare center with a crispy, golden crust. Letting the roast rest before slicing is key—it allows the juices to redistribute for maximum tenderness.
You might know the ribeye by one of its many other names, such as beauty steak, Delmonico steak, Spencer steak, and scotch fillet. Whatever you call it, ribeye steak is the center (and arguably the best) portion of the rib steak. It’s typically highly marbled with fat, which is why this cut is so delicious. But the distinction between prime rib and ribeye is a matter of cooking: To be considered a ribeye, the steak must be cut before the roast is cooked.
Because of its marbling, the ribeye is one of the most flavorful and juicy cuts of beef, making it a favorite among steak lovers. The fat melts into the meat during cooking, creating a buttery texture and deep, beefy flavor that’s hard to beat. Whether it’s grilled, pan-seared, or broiled, ribeye delivers a rich, satisfying experience that requires minimal seasoning—just salt, pepper, and maybe a pat of herb butter.
You can find ribeye sold bone-in or boneless. The bone-in version—sometimes labeled as a cowboy steak or tomahawk steak (when the bone is left long and French-trimmed)—adds dramatic flair and may offer slightly more flavor due to the bone’s insulation during cooking. Boneless ribeyes, on the other hand, cook more evenly and are easier to handle, making them ideal for quick weeknight dinners or special occasions.
When choosing a ribeye, look for good marbling throughout the steak and a bright red color. USDA Prime ribeyes have the most marbling, but even USDA Choice cuts can deliver excellent flavor and tenderness. For best results, let your ribeye come to room temperature before cooking, and rest it for at least 5–10 minutes after it’s done to lock in those juices. Whether you’re firing up the grill or searing in a cast iron skillet, ribeye is a guaranteed crowd-pleaser.
All your burning prime rib questions are about to get answered.
A 4-ounce serving has approximately 453 calories, and an 8-ounce portion clocks in at 900 calories.
We’ll chat more about how to cook prime rib below, but the basic rule of thumb for cooking at a low temperature is 17 to 20 minutes per pound in an oven heated to 325°F.
At the meat counter you can go all in and opt for the entire prime rib, or choose between two options for a smaller cut: the first cut and the second cut. The first cut is made up of ribs 10 to 12, which are uniform and tender, and generally thought to be the best choice. The second cut is still a good option, but the cut includes ribs 6 to 9 and is closer to the chuck roast, which means it’ll include a few different muscles and therefore won’t be as uniform in size or appearance. But with more fatty pockets, it’s a bit more flavorful!
A seven-rib roast can clock in at anywhere between 14 and 22 pounds, which is why butchers tend to divide it into two smaller roasts (see question above). No matter which option you choose, aim for about one pound per person [3].

A 4-ounce serving has approximately 300 calories, and an 8-ounce portion has about 600 calories.
The answer to this question entirely depends on how you’re planning your meal. If the ribeye is the main event, then you’ll want to have about ½-pound per person (about 8 ounces each). But if you’re planning to slice it up and serve it alongside lots of side dishes and salads (maybe at a Paleo-friendly dinner party), then opt for smaller portions, like a quarter to half a pound per person.
The difference is exactly how it sounds. A bone-in ribeye still has the bone attached to the flesh, which is believed to help insulate the meat as it cooks and lock in extra flavor [4]. You can also save the bones and use them to make homemade beef broth.
Here are two ways to cook prime rib.
The first and most time-consuming option is cooking the prime rib at a low temperature for a long period of time. At 325°F, expect it to take about 17 to 20 minutes per pound. Low heat allows the meat to cook evenly and develop extra tenderness.
If you opt for a 450°F oven and cook the meat for 30 minutes, then reduce the temperature to 325°F, you’ll need to cook the prime rib for an additional 13 to 15 minutes per pound. High heat sears the outside for a more flavorful crust.
Regardless of your cooking method, the most important step is allowing the roast to rest after it comes out of the oven. Letting the prime rib rest for at least 20 to 30 minutes helps the juices redistribute throughout the meat, making every slice more tender and flavorful. Cover the roast loosely with foil and resist the urge to cut in right away—your patience will be rewarded.
Don’t forget the seasoning. A generous coating of kosher salt, cracked black pepper, and fresh herbs like rosemary and thyme will enhance the beef’s natural flavor. For added depth, rub the roast with garlic or a smear of Dijon mustard before roasting. You can also dry-brine the meat the night before by salting it and leaving it uncovered in the fridge—this helps create a crispier, more flavorful crust when it’s time to roast.
If you’re using a meat thermometer (highly recommended), aim for an internal temperature of 120–125°F for rare, 130–135°F for medium-rare, or 140–145°F for medium. Keep in mind that the roast will continue to rise in temperature slightly as it rests, so it’s best to pull it out of the oven just before it reaches your target.
Similar to prepping the turkey for Thanksgiving dinner, you’ll want to plan ahead when cooking prime rib. Salt the meat on all sides, then refrigerate uncovered for at least one day (and up to three). The salt rub will season the meat and help dissolve some of the proteins, which means you’ll end up with a tender, buttery roast that’ll melt in your mouth. Exposing the meat to air will also help dry out the exterior to make for better browning.
Before adding a dry rub, score the thick fat cap in a cross-hatch pattern, cutting down to—but not into—the flesh. The fat’s job is to insulate the meat and crisp up when exposed to high heat, encouraging rendering for maximum flavor. Plus, the shallow cuts will help seasonings infuse every bite.
When you’re dealing with a prime cut, it’s a good idea to know how to cook the best cuts of meat. A ribeye lends itself perfectly to pan-searing. Steaks should start off extra dry—so pat them well with paper towels, then season generously with salt and pepper. Heat a cast iron pan, add a slick of cooking oil, then cook, flipping frequently, until the internal temperature reaches 135°F. Depending on the thickness, the ideal cook time for a ribeye steak might range anywhere between 6 to 12 minutes. When they’re cooked to your liking, let the steaks rest, tented with foil, for 10 minutes before carving.
Pan-searing in a cast iron skillet creates the perfect golden crust, thanks to the high, even heat. Flipping the steak every 30–60 seconds helps it cook more evenly and develop a beautiful sear without overcooking the interior. For added flavor, toss in a few smashed garlic cloves, fresh thyme or rosemary, and a tablespoon of butter during the last couple of minutes. Baste the steak with the melted butter and herbs for a restaurant-worthy finish.
Prefer to fire up the grill? Ribeye performs beautifully over open flame. Preheat your grill to high and sear each side for 3–4 minutes before finishing over indirect heat. Whether you’re using gas or charcoal, be sure to let the steak rest afterward—this allows the juices to redistribute and keeps every bite tender and flavorful.
To check for doneness, use a meat thermometer rather than guessing. Pull the ribeye at 130–135°F for medium-rare, or 140°F for medium. Remember: the steak will continue to cook slightly as it rests, so don’t be afraid to take it off the heat a few degrees early.
