How to Cook Prime Rib Perfectly at Home

Last Updated on 27th January 2023 by

Prime rib makes for great addition to your dinner, complementing potatoes, bread, and veggies nicely. But cooking prime rib can be a little tricky for someone who’s never done it before.

You may be wondering how to cook boneless prime rib or maybe you just want ways to cook prime rib that you’ve never tried before.

I want to share with you some cooking methods you can use depending on what kind of prime rib you’re using and how you want the dish turn out.

I’ll talk about the different temperatures you can use and how that affects the prime rib so that you get it to come out perfectly every time.

This is the kind of dish you don’t want to mess up, because people really look forward to prime rib when you tell them it’s on the menu. It’s one of those meats that is considered a choice cut, so you want to do your very best with it. It’s not something you want to jump into head first unprepared.

If you’re looking to do right by a cut of prime rib, I’ve got you covered.

What Is Prime Rib?

Prime rib is a prime cut of beef that has been taken from the midsection of the cow. It typically has seven rib bones attached to it, and then it will be cut into nine pieces from there with the smaller parts known as primal cuts.

One of those smaller pieces is the prime rib, and it’s taken from ribs 6 through 12. Some people get it mixed up with prime beef cuts, which is not a specific part of the cow but is rather a grade of meat.

This is typically a very large cut of meat, so it will need to be cooked for a long time, usually at a lower temperature than you might expect, and it will need to be well seasoned too.

When you prepare prime rib, you probably have to add more seasoning than you think, just because there’s so much surface area to deal with.

How Long to Cook Prime Rib?

Cooking times are going to vary based on the size of your prime rib, what temperature you’re cooking it at, and how tender and juicy you want the prime rib.

325 degrees Fahrenheit is the standard cooking temperature for most prime rib recipes. If you’re making the meat medium rare, you want to cook it for about 20 to 25 minutes for each pound prime rib. For a medium cooked prime rib, cook it for 25 to 30 minutes per pound, and for medium-well, you can cook it for 30 to 35 minutes for each pound.

How to make prime rib at 350 degrees Fahrenheit? For medium rare, you can cook it for 15 to 20 minutes for each pound. Medium requires 20 to 25 minutes a pound, and medium well requires 25 to 30 minutes a pound.

If you’re going to be cooking prime rib the next day, make sure that you allow it to thaw out the night before. It can take several hours to thaw completely from frozen, so keep that in mind when you’re planning how to cook a prime rib. If the prime rib is big enough, it could take several days to thaw completely.

How Is Prime Rib Cooked?

Make sure that you thaw out the prime rib completely before you try to cook it. Also make sure that when you season it, you use plenty of seasoning. This tends to be a large cut of meat that could do with plenty of seasoning to make the taste really pop.

Once your prime rib is fully thawed, you can set it out at room temperature for a few hours. About four hours should be enough for most cuts of prime rib. You cut down your cooking time by allowing it to come to room temperature.

Slow cooking is ideal for this meat, as it shows that the meat is cooked all the way through and helps it to retain juiciness and flavor. For the ultimate slow cooking method I like to use for how to cook a prime rib that is succulent and tender, I set the oven for 225 degrees Fahrenheit.

With this temperature, that means the cooking time needs to be 30 to 35 minutes if I want it medium rare. For medium prime rib at 225 degrees, I expect it to take 35 to 40 minutes per pound. For medium well, it should be 40 to 45 minutes per pound.

You should check the prime rib about 30 minutes before it’s supposed to be done. A medium prime rib should reach 130 degrees Fahrenheit for medium cooking.

How to cook a prime rib roast that comes out perfectly? You want to allow it to rest after it comes out of the oven. Cover it with foil and let it rest for 15 minutes at the very least. It can rest up in hour before you eat it.

How to Reheat Prime Rib

The method I’ve given you for how to cook prime rib in the oven is missing one little step. You can reverse sear your prime rib by putting it in the oven at 550 degrees Fahrenheit.

You want to take the foil off, and make sure it gets a seared look on the outer skin. That should take about 8 minutes.

You can use this exact same method for reheating the prime rib. If you’re wondering what to do with leftover prime rib, it can be used in sandwiches or reheated and served as part of your larger meal.

You’re supposed to wait to slice the prime rib until it has rested properly, which you can do if you reverse sear it. Once it’s sliced, it’s ready to serve. You should have an incredibly juicy and tender meat that’s a makes for a great addition to the rest of your meal. It’s sure to be the highlight, though.
