Prime rib vs ribeye - what's the difference?
You've come to the right place.
We explain the major differences in taste, cooking style, and for feasting.
And you'll learn how to cook these amazing cuts of beef better.
Let's break it down.
What Cut of Meat is Prime Rib?
Prime rib is considered to be the traditional roast beef that many of us have enjoyed for Sunday family dinner. Prime rib is a beef that is cut from the rib eye muscle that is located up high on the back of the animal.
The cut includes the sixth to the twelfth ribs of the cow, right between the short loin and chuck section of the animal. This rib eye muscle isn’t exercised as much as other areas of the cow and therefore is one of the most tenderest portions of meat from the animal.
What Cut of Meat is Ribeye?
The ribeye roast is cut from the primal rib of the animal, which is found underneath the front section of the backbone.
The meat can be cut into both a roast and individual ribeye steaks – both offer a rich and tasty cut of meat that has just the right amount of fat marbling throughout.
What Does Prime Rib Taste Like?
When you eat prime rib, you can’t mistake the taste – the meat is rich and tender, juicy and full of intense beef flavor without being overwhelming.
Not all prime rib is cooked with the bone in but keeping the bone in while cooking adds more moisture and flavor.
The meat roasts gently and evenly around the bones, giving prime rib the beautiful beefy taste that it’s known for.
Prime rib is at its best when cooked to a medium-rare. When cooked to more than medium, the meat starts to lose its tenderness.
What Does Ribeye Taste Like?
Ribeye, whether cut as a roast or into steaks, is one of the most tender parts of the cow. Because it comes from the upper rib cage, this area of the animal isn’t used for weight-bearing or much movement.
The less a muscle is used, the more tender the meat will be. It’s also the marbling of fat in the ribeye that gives it a buttery and rich taste. When cooked, the fat in the meat renders down and melts so that it bastes the ribeye from the inside.
This enhances the juiciness and tenderness of the meat.
What Cut of Meat is Used for Prime Rib?
Cut from the beef rib, prime rib is cut from the choicest part of the rib. Not only is it the most tender part of the cow, it also has excellent fat marbling which adds even more flavor and moisture to the meat.
The amount of marbling in the muscle of the rib eye is one of the most important considerations when it comes to grading meat – the more marbling there is the higher the grade of the cut.
What is Prime Rib vs Ribeye?
Often called a standing rib roast, prime rib comes from the same part of the cow as the ribeye – the primal rib area. One of the biggest differences when it comes to prime rib vs ribeye roast is the cost, which is based on the cut of the meat.
Both prime rib and ribeye can be cut in various ways. Prime rib can refer to the whole rib roast which you can then carve into individual portions. Prime rib is typically purchased with the bone in, although you can also order with the bone removed.
Ribeye can also be bought with the bone in or out. The boneless cuts for both prime rib and ribeye are more expensive than those with the bone in. As a rule, prime rib will give you a bigger cut of meat that contains the ribeye area of the animal as well.
The ribeye will give you the best cut of meat but in a smaller size cut.
For both cuts of meat, keep in mind that cooking with the bone in will keep the meat more tender and juicier.

What Taste Better - Prime Rib vs Ribeye?
The taste of prime rib vs ribeye roasts is quite similar, although there are a couple of differences. The prime rib roast has fat that is marbled both around and inside the roast.
If the cut is taken from the larger end of the cow, the ends of the roast can be tougher. If the prime rib roast is cut from the smaller end of the animal, the meat is more tender and leaner.
The ribeye roast is usually cut from the smaller end of the rib and so is always marbled and tender.
