I can’t take credit for this recipe. It’s a family favorite that’s been passed on to me. And my mom got it from a military wives cookbook. I usually like to tweak recipes and make them my own. But not with this recipe. It’s perfect just the way it is. Prime rib is often our main dish at celebrations. My parents have been making prime rib this way for years. When I was putting together my first big celebration dinner, I had to have the recipe. Over the years I’ve made it in many different ovens, and it comes out perfect every time.

Which Roast do I Buy?


Besides coming out perfectly cooked every time, this prime rib recipe only has three ingredients. It really can’t get any easier. And it makes for great stress-free entertaining. The most important ingredient for this recipe is the roast. And not all beef roasts are the same.

In this case, you’re looking for a standing rib roast. You can also use a rib eye roast, which is a standing rib roast with the ribs removed. If you’re at the grocery store and can’t find either of these roasts available, there is one more option. Buy rib eye steaks, which is sliced rib eye roast. They can be bone-in or bone-out. You will also need cooking twine, so pick some up if you don’t have any at home. Then, stack the rib eye steaks together and tie them tightly with the cooking twine. Essentially, you’re putting the roast back together. (Bonus: Less work cutting later) I have had to “make” my own roast before, and it came out delicious.

How to Tie a Roast with Twine

Here’s a quick video showing you how to tie a roast with cooking twine.

Cooking the Prime Rib Roast

To prepare your roast, let it sit out at room temperature for at least one hour before cooking. Then, generously coat the roast with kosher salt and pepper on all sides. Rub the salt and pepper in. Place the prime rib in a shallow roasting pan, fat side up. Pre-heat the oven to 375°. Roast your prime rib for one hour, and then turn off the heat. Do not open the oven door or take out the roast. Leave the prime rib in the oven. Thirty to forty minutes before you’re ready to serve, turn the oven back on to 375°. Your prime rib will come out brown and crispy on the outside and rare in the middle. Let the roast rest at room temperature. Then, all you have to do is slice and serve.

I like to have nice and clean looking pans, especially for pictures. If you want to have stunning and shiny baking pans that last, try these nice stainless steel baking pans. These are what I use all the time and in the pictures above. The best thing is they stay looking nice because they are so easy to clean.

DO NOT Open the Oven

I repeat, do not open the oven. This is so important. If you open it, the oven it will lose its heat. Then, your prime rib roast won’t be properly cooked in the middle. So, this means you can’t cook anything else in the oven. When you’re planning your meal, plan on making your side dishes elsewhere. Make your side dishes on the stove-top or on the grill. A great salad also goes wonderful with prime rib. If you have double ovens, you don’t have to think about where to make your sides. But, you do have to make sure your kitchen helpers don’t open the oven.

Do you find it difficult to keep your cutting board clean. I really like using the plastic cutting boards on top of my bamboo cutting board. The best thing is I can put the plastic cutting boards in the dishwasher. Many people find it annoying to have a bunch of plastic cutting boards, but with this cutting board above, the plastic ones store inside the bamboo cutting board. It you like it you can find it on Amazon here.

      Hi Steve, Good question. I have not made a roast that big. I would recommend cutting the roast into four large pieces first. Put them on a large baking pan with room around each for even cooking. Then follow the recipe directions. Hope this helps.

      Hi Teresa,
      The time it sits in the oven with the heat off can vary. For me, it’s usually 3-4 hours. That way I can prepare other food and clean up the kitchen before guests arrive.

    I make this recipe for Prime Rib.. It is perfect every time.. The only thing I do different is, I add garlic powder to the, and let it set…

      Hi Kathleen, follow the recipe above. Let the roast sit in the warm oven for at least 3 hours. Bake for 30 minutes, and the prime rib should be medium on the inside. You can adjust the final bake time to achieve your desired doneness.

    Merry Christmas! I have a 14 pound Prime Rib that I need to come out Medium Rare. I really didn’t want to cut it as I was looking for presentation, but should I? How long should it sit in the warm oven and how long should I bake it at the end?

      Hi Dana, I understand not wanting to cut such a beautiful roast. For the larger size, I would suggest letting it sit in the oven 3-4 hours and then baking for another 30 minutes.

    1. Megan C

      Michelle, that sounds like a wonderful meal. I’m happy to hear you were able to adjust the time for a smaller roast. Do you remember how long you cooked it for? I have not made goat stew before, but that sounds like a fun meal to try. Happy New Years!!

    Great recipe! And so easy! I should probably have baked the potatoes in the toaster oven (a 3 hour baked potato is a challenge) but, the roast was perfectly medium inside and tasty and tender! I was very happy with this recipe!

    thank you for the recipe. I have my first prime rib and I’m ready to give this recipe a try. I’ve seen mention on other sites that a newer oven with a fan can be a problem for this method. Have you heard this and what are your thoughts?
