How to cook Prime Rib?

Follow the below steps to cook a perfect prime rib:

Step 1- Prepare the oven

Preheat the oven to 325 degrees F. Note, which should be done at least 30 minutes before the meat is ready for cooking.

Salt and pepper the meat on all sides. Weigh it to determine cooking time. Add one hour under three pounds, 2 hours for an average size roast between 3-8 pounds, or 3 hours for a large roast over 8 pounds.

Step 2- Sear the Meat

Sear the meat quickly in a frying pan with oil to form a crust on all sides. Transfer to a baking dish large enough to hold it without crowding.

Step 3- Let it come to room temperature.

Place the meat in the fridge until it comes down to room temperature. Remove 30 minutes before cooking.

Step 4- Cook the Prime Rib

Place a roasting rack in the baking dish and place the prime Rib on top of it to allow for even cooking.

Cook at 325 degrees F for 1 hour per pound, or 120 minutes maximum if under 3 pounds, 170 minutes maximum if over 3 pounds.

Step 5- Bring the steak to temperature.

Remove the meat from the oven after reaching your desired level of doneness (rare, medium-rare, medium, etc.).

Allow it to rest for at least 10 minutes on a cutting board before serving. This is important because this will allow for the reabsorption of juices running out during slicing.

Step 6- Carve and serve

Cut the meat across the grain to prevent it from toughening. Serve at once with your choice of sides! Cut thin slices for a final tender product, or thick slices if you prefer a heartier cut.


1- 3 pound meat, whole

2- Olive oil

3- Salt

4- Pepper

5- Roasting rack

6- 1 hour per pound

7- 10 minutes

8- Cutting board

9- Sides, e.g., carrots, mashed potatoes, a salad, etc.

How is prime Rib supposed to be cooked?

The Prime Rib is best cooked to medium-rare, where the meat will be pinkish-red in color and juicy.

The best way to cook a prime rib is the following:

Take the meat out of the fridge about an hour before cooking so that it can come to room temperature (or cook it cold, but at a lower oven temperature). Preheat the oven to 500 degrees Fahrenheit (250 degrees Celsius).

Pat dry with paper towels or coat with oil. Place aluminum foil on a baking tray. Cook for 15 minutes per pound (450g) plus an additional 30 minutes.

Take out of the oven when the meat has reached the desired doneness (check with a meat thermometer) and let rest for 15 minutes for the juices to settle.

How many hours does it take to cook a prime rib?

It takes around 3 and a half hours to cook a prime rib.

Do you cook prime Rib covered or uncovered?

You can either cook it uncovered or in a baking pan with the lid (either the one that came with it, or if you’re alone and making your own, a disposable aluminum foil roasting dish) for about 20 minutes.

The trick to getting any cut of meat juicy is not to overcook it. Remove it from the oven when it reaches 120 F for rare, 130 F for medium-rare, 140 F for medium, and none of them should be cooked past 160.

Do you cook prime Rib at 325 or 350?

Normally, I would say that 325 degrees Fahrenheit is the right temperature for cooking a prime rib roast. 

However, if your roasting pan doesn’t provide enough insulation, you should cook the roast at 350 degrees Fahrenheit.

How long does it take to cook a 5.5-pound prime rib?

 It typically takes at least six hours to cook a 5.5-pound prime rib. You can make a larger or smaller roast, but the cooking time will be adjusted accordingly.

What temp should prime Rib be cooked at?

When cooking your Prime Rib, keep in mind that the temp of the oven should be 425 degrees for rare, 450 degrees for medium-rare, 475 degrees for medium, and 500 degrees for well done. 

It is important to remember that if you are cooking a bone-in piece of meat like a prime rib, the cooking times will be higher than if you were cooking with boneless cuts of meat.

What’s the difference between prime Rib and rib roast?

As you can see from the cut, the Prime Rib is a single bone-in roast that cuts away from the ribs. The Rib Roast cuts between the ribs and chops off both ends of the bones.

Because of this, a rib roast is easier to carve if you decide to shred the meat. It also has a larger piece of bone for those who like to suck on bones.

Should I let prime Rib come to room temperature before cooking?

No, prime Rib should never be allowed to come up to room temperature before cooking.

How much prime Rib do I need for 4 adults?

An average rib roast is about 5-6lbs and will feed 4 people. 4 adults who want a 2 1/2 inch serving should have a 1lb roast so the meat wouldn’t be too fatty.

Do you put water in the pan when cooking prime Rib?

No, but it is recommended to use a large roasting pan to hold the beef and any vegetables you want to roast.

Add salt, pepper, and other herbs you might like, such as smoked paprika or thyme.

Place your roast on top of the vegetables and cover tightly with aluminum foil.

Roast in an oven at 350 degrees Fahrenheit for about 15 minutes for each pound–or until pink juices leak out. Remove from oven and let stand for 10 minutes before slicing into thin strips.

Should you sear Prime Rib before cooking?

Yes, searing a prime rib before cooking will help seal in the natural juices from the meat and improve flavour. The outside layer of beef becomes caramelized due to the cooking process, so it has a rich, well-browned crust when you serve it.

Should I salt my prime Rib the night before?

It’s a common temptation to salt the prime rib hours before cooking, but this is a bad idea.

Prime ribs need plenty of time to release moisture and allow for even penetration throughout their mass; salting well before cooking could lock those juices in, hampering your end goal.

It’s always better to salt once the meat has been properly heated through and allowed enough time for rest (usually about 10-15 minutes).

How long does it take to cook a 7.5-pound prime rib?

A 7.5-pound prime rib of beef should take about 1-2 hours to cook in an oven at 500°F.

How long does it take to cook Prime Rib at 375 degrees?

Ten minutes per pound is a general rule of thumb for cooking a roast in the oven, but this is also contingent on the shape and thickness of the meat.

For medium-rare beef, roast it from about 135 degrees to 145 degrees Fahrenheit for one hour or from 150 degrees to 155 degrees Fahrenheit for 45 minutes to an hour.

How long does it take to cook a prime rib roast at 250 degrees?

The total cooking time for a prime rib roast at 250 degrees is about 30 minutes per pound.

How long does it take to cook a prime rib roast at 225 degrees?

At 225 degrees, it will take about 20-25 minutes per pound, and at 300 degrees.

Which is better prime Rib or ribeye?

The ribeye is cut from the rib section, thus the name. The Prime Rib (often referred to as a standing rib roast) is roasted whole and then carved into individual ribs, more like table cuts of meat.

One of these two cuts will often be what you find on your dinner table at a restaurant; it’s always good to know about both!


Prime Rib and ribeye are two different cuts of beef. Prime ribs come from the front section of the cow, while ribeyes come from the back.

One is roasted whole before being carved into individual servings that can be served to guests at a dinner party or gathering with friends, while another cut is often what you find on your table at restaurants because it’s easy to serve.

If you’re looking for an excellent choice for your next family meal or get-together with friends, prime Rib is just maybe your best bet!
