Tips for Making Rib Roast

Buying Prime Rib

Prime Rib can go by a couple of different names in the grocery store. They include: Holiday Roast, Ribeye Roast or Standing Rib Roast. The Ribeye Roast is our favorite, it comes from the rib primal which gives it sought-after beefy flavor. The epic marbling can be found boneless or bone-in. For more tips on buying a Rib Roast, check out this blog post from Natasha’s Kitchen.

Preheat Oven and Prep the Roast

Set the oven to 350 °F and season your roast while it heats up. Make sure you rub the seasoning all over the roast generously.

Cooking Your Beef Prime Rib

The best way to roast Prime Rib is fat side up in the oven to medium-rare or medium doneness. Then, allow the beef to rest tented by aluminum foil for at least 15 minutes before you cut into it. Allowing your meat to rest locks in its juices! Remember that not all roasts are identical. Their sizes vary and cooking times change depending on if they are boneless or not. See cooking times chart below.

Note: During the resting process, beef will cook an additional 10-15 degrees. Take this into account when determining your desired doneness. For example, if you want to cook your roast to medium-rare (145 °F) remove it from the oven at 135 °F to let it finish cooking on the counter.

Invest in an Oven-Proof Meat Thermometer

Purchase an oven-proof electric meat thermometer to take the guesswork out of gauging doneness. Instead of opening the oven unnecessarily and losing juices when you keep poking the meat for doneness, the readout for the thermometer remains on the outside of the oven.

How to Carve Prime Rib

If your roast is bone-in, first turn it on its side and remove the ribs. Hold the roast steady by grasping a piece of rib bone that is sticking out. Using a sharp knife, follow the curvature of the rib bones as closely as you can. Now that your cut is boneless, start carving the meat from one of the ends, slicing across the grain for maximum tenderness. Slice pieces about ½-inch thick. 

Do You Cover Roast Beef in The Oven

The only time you should lightly cover your roast is when you are allowing it to rest and come to doneness on the counter. Do not cover it in the oven. You want the outer edges to crisp up nicely. Covering the roast would prevent the direct heat from forming a crust. 

Note: If the outside of your roast is getting too dark, it’s OK to cover with foil and continue cooking at the same temperature.

How Much Prime Rib Roast do I Need Per Person?

You may be wondering how much Prime Rib you should buy at this point. A general rule of thumb is to plan on one rib per two people. While most won’t eat a half a pound, this rule helps you prevent from underbuying (the worst!). As my grandma said, “It’s better to have leftovers than to not have enough food!”
