Sometimes only the best will do, and when you are looking for the very finest steak to serve for dinner you want to choose between Prime Rib Vs Ribeye.

Whether you are choosing between ribeye vs prime rib for the holidays or special occasion, it’s important to know the differences between the two popular cuts of primal meat.

❓ What is Prime Rib (Standing Rib Roast)?

This beef primal rib section cut is top of the line beef. It doesn’t get any better than this. Cooked as low and slow as possible, prime rib comes out incredibly tender and full of flavor with a melt-in-your-mouth texture.

Prime Rib is also called standing rib roast, rolled-rib roast (when it is a perfectly rolled prime rib removed from the bone to allow for even cooking), or ribeye roast when it is taken from the very center of the prime rib but kept in roast form.

Standing Rib Roast and Prime Rib are often used synonymously and can be confusing until you think of it this way. If you are at a restaurant and order Prime Rib, you will be getting a slice of the standing rib roast.

Prime rib and ribeye are closely related as ribeye steaks are taken from the very center of the rib roast. Taken from the fatty section of 7 back ribs of a cow, between the chuck roast and the short loin.

A whole intact prime rib may contain up to 25 pounds of meat, but it is more typical for the it to be divided in halves or thirds before it is sold for anywhere between 8 and 13 pounds. Because of its size, it is often associated with holiday gatherings and special events. Don’t worry about getting one too large as it’s easy to reheat prime rib.

Note: The word “prime” rib in this case does not refer to the USDA grading system. It is important that you still look for “prime” prime rib or “choice” prime rib which delineates quality.

🙋 What is Ribeye?

Most people consider ribeye steaks to be the very best part of the prime rib. It is a cut of meat taken from between the ribs at the very center of the prime rib and is considered the best steak money can buy. The flavor is rich and intense while the texture is sublime when properly cooked.

Ribeye may also be called boneless rib steak, entrecot (Spanish) and Faux filet (French Canadian).

🍖 How to Choose

When choosing between prime rib and ribeye one of the considerations is cost. Prime rib is technically cheaper, but because it comes in rack form you may end up having to buy a lot more than initially planned, especially if it has the bone-in.

For prime rib as your main dish, you need to plan about one pound per person. For ribeye, plan for a half pound per person. The difference is because of the bone in prime rib. All of these factors impact your final cost.

Another consideration as you make your choice is cooking method. Which will work better for your dinner or event? A prime rib needs to roast for about fifteen minutes per pound in an oven or smoker. Ribeye is typically grilled or smoked in a fraction of the time but requires a more hands on approach. Will you have someone dedicated to the grill or is it better to have the meat in the oven?

Because the taste, texture, and flavors are virtually the same, these comparison points are rarely a factor when you make the choice.

One final thing to consider is how your dinner guests will respond to eating meat on ribs vs boneless ribeye.

🍳 How to Cook

Prime Rib

Prime Rib is usually seared and then cooked in roast form at a low-and-slow medium finish. It has slightly more connective tissue and fat marbling than ribeye steaks and all of that needs to render down.

To sear the prime rib, start with the oven at a much higher temp or sear the exterior on a very hot skillet. Once the outside of the meat has seared nicely, lower the oven temperature to allow a low-and-slow roast.

As the meat cooks, the marbling of fat renders and the seared exterior keeps it tender and juicy. This is also where the flavor comes from. Prime rib is often served with aus jus or with horseradish to add moisture and is cut into servings at the table or buffet.

Tent the meat and let it rest for a minimum of fifteen minutes before slicing.

Ribeye

Sear your ribeyes on high heat and cook them fast as individual steaks, charring them slightly on the outside and serving them medium to medium rare right off the heat.

If you prefer, cook your rib steaks in a hot cast iron skillet or on a grill and both methods will yield amazing results. Print out the Grilling Times and Temperature Chart to make sure each steak comes out perfectly!
