What is Prime Rib?

Prime rib is one of the most tender pieces of beef you will ever taste! It melts in your mouth like no other cut of beef!

A boneless rib roast comes from the rib area towards the top of the animal. It’s the same area as ribeye steaks, just left as a larger piece. A prime rib roast is often considered the king of roasts since it has that wonderful combination of flavor, marbling, and tenderness.

The prime rib roast comes in two different forms, bone-in and boneless. A Standing Rib Roast is arguably more impressive, but a boneless prime rib is super easy. It’s a lot easier to carve and you can adjust serving sizes easily too.

How long do you cook a boneless prime rib roast?

As with any cut of beef, the length of time you roast a prime rib depends on the size. With beef, in particular, you have the added factor of adjusting to different levels of doneness in the time you cook.

All of this can make getting the timing right tricky but thankfully Certified Angus Beef® brand has created a free app called Roast Perfect which takes away the guesswork.

How to use the Roast Perfect app

How to Cook a Boneless Prime Rib Roast

A boneless prime rib roast is such a flavorful cut of beef that it doesn’t need a lot of dressing up.

Take the roast out of the refrigerator 30 minutes before you will be cooking it to allow it to come to room temperature.
Preheat the oven to 450°F.
Pat the roast dry and rub all over with the salt and pepper.
Place the prime rib roast on a pan with a roasting rack, fat side up.
Put the roast in the oven and cook at the high heat for 15 minutes
Reduce the temperature to 325°F.
Cook for an additional hour and 40 minutes (note – you can check the exact time by using the roast perfect app based on the size of your roast and the level of doneness you are looking for).
As the roast is cooking, mash together the butter, parsley and garlic and form into a mini log. You can follow our step by step instructions on how to make garlic butter.
Refrigerate until needed.
Once the beef is cooked, remove from the oven, transfer to a cutting board.
Loosely tent the beef with foil for around 15 minutes.
Carve the beef against the grain. Always, always carve against the grain.
Serve with garlic butter.

To finish off the dish, you could easily make a simple gravy using the juices, but for just a touch more flavor, a simple herb and garlic butter is a great addition, as I made here.
