What is Prime Rib?

A prime rib and a ribeye steak come from the same cut of beef. The real difference is how they are prepared. The ribeye steak is grilled on high heat searing the outside. Where as, a prime rib is cooked in an oven. Sometimes a grocer may call this type of roast a standing rib roast. It is really like a stack of ribeye steaks rather than being cut into individual steaks.

Beautiful marbling gives the flavor and tenderness gets a boost too.

Easily Prepare Prime Rib Eye Roast for the Holidays

Let the prime rib take center stage during the holiday season. With beautiful marbling; this roast is tender and juicy.

Do not be intimidated by this roast. It is extremely easy to cook.

Just start with a roasting pan and a hot oven to help brown the outside of the roast. Once brown, turn down the heat for a slow roast, assuring that the center of the meat is cooked just perfectly too.

Then let rest at room temperature before slicing, this will keep the juices inside.

Please Everyone with This Roast

For those that like their rib eye cooked medium well, they will enjoy the ends of the roast. Yet, those that like their roast on the rare side, they will enjoy a rib eye cut closer to the center.

A rib eye roast is generally 8-9 pounds. Therefore, this delicious meat will feed a minimum of 8 people if each person is sliced a thick 1-pound steak.  

However, it could feed up to 16 people if each person by slicing a thinner ½ pound steak.

How to Buy a Prime Rib Roast

When purchasing prime rib, look for marbling. Marbling is the fat that runs through the meat. It adds lots of flavor, keeps the meat moist throughout.

You can purchase a roast with or without the bone. Ask your butcher at your grocery store to remove the rib bone from the meat if you wish.

The best rib roast you can purchase is a prime grade beef, the next grade is select or choice. To be honest, they have all turned out really well for me.

Purchasing Meat on Sale

I purchased two prime rib eye roasts on sale a few weeks ago. They were 70% off! What a deal; I should have purchased more than two! I froze one and cooked the other one right away. When using the frozen one, just thaw prior to cooking.

For ease, I prefer the boneless roast; however, the bone-in roast will provide more flavor.

How Much Prime Rib to Plan Per Person?

If you think about the ounces of ribeye steak you are served in a steak house, that will help you calculate how much prime rib to plan per person. Often, a cut of steak at your favorite restaurant ranges between 6 ounce, 8 ounce, and 12 ounce.

Since I will be serving this meat with other sides and a dessert, I plan on 8 ounces a person. Simply multiple the number of servings by 8 ounces and you will have the pounds of prime rib to purchase. For example, if you are having a part of 6, multiply 6 servings by 8 ounces a serving, 48 ounces or 3 pounds of meet should be purchased.

What is the Best Way to Cook a Prime Rib?

Begin roasting at a high temperature for a short period of time, then reduce the heat to a lower temperature setting and continue at this setting for the remainder of the cook time.

Preparing the roast. Generously sprinkle salt all over the roast and return it to the refrigerator for 1 hour. Remove from the refrigerator 1 hour before cooking to help bring the roast to room temperature before cooking. This will help ensure more even cooking.

Pat the roast dry with paper towels as the pre-salting makes the roast release some moisture. I like to keep my seasoning simple. Then sprinkle roast all over the salt and black pepper and place fat side up in a baking pan large enough to hold the rib eye roast.

Preheat the oven to 500 degrees Fahrenheit.

Bake the roast uncovered for 15 minutes. This will help brown the roast.

After 15 minutes, lower the oven temperature to 325 degrees Fahrenheit. Cook the roast for 10-12 minutes per pound for rare and 13-15 minutes per pound for medium rare.

I started checking the roast with a thermometer after 1 hour 15 minutes of cooking. Then continued to check every 15 minutes. Remember to use the temperature of the roast to tell how done the meat is.

For the 8 pound roast, I baked mine for 1 hour 45 minutes, plus the initial 15 minutes – total cook time was 2 hours.

For best results, let the Roast Rest once it is removed from the oven. This helps the juices go back into the meat. Cover it and let rest for 30 minutes. Remember, the internal temperature of the roast will continue to rise as it rests.

Make Sure to Use a Meat Thermometer

I highly recommend the use of an instant-read thermometer as the temperature will help you determine if the meat is rare or well-done.

What Temperature is Rare and Medium for the Meat?

Temp the meat at the thickest part of the roast.

When the thermometer registers 115 degrees Fahrenheit the meat is rare.

At 120-130 degrees Fahrenheit, the meat is medium.

Note: the internal temperature of the roast will continue rising a bit after it is taken out of the oven.

 The actual cooking time for the meat will depend on a few factors:

  • Shape of the roast-a flatter roast will cook faster than a thicker roast
  • How chilled the roast is when it is put in the oven-a chilled roast will take longer to cook
  • The actual temperature of your oven-the temperature varies with some ovens.

While it is nice to have a fancy meat thermometer, it is not necessary. This is the kind that I use.

Au Jus Gravy for the Meat

Making Prime Rib Au Jus

You may choose to make a gravy from the pan drippings.

If you do, once the roast is removed, pour the drippings in a measuring cup that also separates the fat from the liquid. Pour 1 cup of the liquid back in the pan. Put the pan on the stove on medium-high heat. Using a metal spatula to scrape the pan drippings if there are any goodies sticking to the pan.

While the pan drippings are coming to a boil, in a separate cup, mix 1/4 cup of flour with 3/4 cup water. Once the pan drippings are boiling, whisk in the flour and water mixture.

Continue to whisk while slowly adding 3 more cups of water. Once the mixture starts to thicken, remove from the heat. If you would like your gravy a bit creamy, once the gravy is off the heat, whisk in a cup of milk.

Taste the gravy as you may have to season it with salt and pepper before serving.

How to Reheat Leftover Prime Rib?

The preferred method is to bake in a preheated oven. Preheat your oven to 275 degrees Fahrenheit. Add the slices of prime rib to a small baking pan with a few tablespoons of broth or water. Bake until the prime rib slices feel like they’ve heated through, about 10-15minutes.

I have reheated this meat in a microwave. To help the meat cook through quickly without overcooking, I cut the meat up into bite size pieces. Then heat for 30 second increments until warm.
