What is a Prime Rib Roast?

Rib roast is a large cut of beef from the primal rib. It includes 7 rib bones and a lot of marbled muscle. They can weigh up to 30 pounds!

Rib eye steaks are cut from the rib roast individually.

If you see a package labeled prime, it doesn’t refer to the quality of the meat but the fact it comes from the primal rib area.

Prime grade meats tend to have more marbling which leads to more flavor and tenderness from the fat.

It also means a pricier cut of meat, but if it is in budget, you won’t be disappointed with it.

  • 2 tablespoons Worcestershire sauce
  • 4 cloves garlic (minced)

How Much Smoked Prime Rib Per Person

How Long to Smoke a Prime Rib?

For a rare roast, plan 35 minutes per pound at 225 degrees.

If you prefer a medium roast, you’ll be looking at 40 minutes per pound at 225 degrees.

Allow for 30 minutes to rest the prime rib when it’s done and 15 minutes for high temperature searing to give that crispy edge.

Tools Needed to Make Smoked Prime Rib

One of the most important tools needed to make smoked prime rib is the cooking element.

A good grill or smoker that gives consistent, even temperature will yield the best results.

Another tool you’ll want for a good smoked prime rib is an instant read thermometer.

Since you’ll need to check the internal temperature a few times during cooking, you want something quick and durable.

How to Make Smoked Prime Rib

Preheat and Prepare

Start by preheating your grill or smoker to 225 degrees.

While waiting on it to heat up to temperature, trim away the excess fat on the top.

Season It

Combine the Worcestershire sauce, garlic, and mustard in a bowl.

Coat the entire roast liberally with the mixture and sprinkle with salt and pepper.

Smoke It

Once you’ve seasoned the roast and the grill is ready, it is ready to go on the grill.

Cook it until the internal temperature reaches 120 degrees for rare or 130 degrees for medium.

Rest the Roast

Once the desired temperature is reached, remove the roast from the grill and put it on a large cutting board, covering it with foil.

Let it rest for 20 minutes.

During the resting time, turn the temperature up on the grill to 400 degrees.

Sear the Roast

Once the grill is at the appropriate temperature, return the roast and sear it until it reaches the desired internal temperature.

For a rare roast, remove it at 130 degrees. For medium rare, you’ll want 135 degrees and for medium, 140 degrees.

Rest, Slice and Serve

After the roast reaches the temperature for how well you want it done, remove it from the heat.

Let it rest for 15 more minutes and you’ll be ready to cut and serve it!
