How Long to Cook Prime Rib at 250 Degrees?

Prime rib is a classic and delicious cut of beef that makes a great centerpiece for any special occasion. Cooking prime rib at a low temperature of 250 degrees Fahrenheit can result in a perfectly cooked and juicy roast that is sure to impress your guests.

However, getting the timing right is crucial to ensuring that your prime rib is cooked to perfection. In this article, we’ll discuss how long to cook prime rib at 250 degrees, from choosing the right cut to resting and carving the meat.

Choosing the Right Cut of Prime Rib

Before you start cooking, it’s important to choose the right cut of prime rib. There are two types of prime rib: bone-in and boneless. Bone-in prime rib is often considered more flavorful because the bones add extra depth of flavor to the meat. Boneless prime rib, on the other hand, is easier to carve and may be more convenient for some people.

When choosing your prime rib, look for a well-marbled cut with a nice layer of fat on top. This will help keep the meat moist and flavorful as it cooks. It’s also a good idea to choose a prime rib that is large enough to feed your guests, but not so large that it won’t fit in your oven or cooking vessel.

Preparing the Prime Rib

Before cooking, it’s important to prepare your prime rib properly. First, take the prime rib out of the refrigerator and let it come to room temperature for at least 1-2 hours. This will help the meat cook more evenly and prevent it from being cold in the center.

Next, season the prime rib generously with your favorite spices and herbs. Some classic seasonings for prime rib include garlic, rosemary, thyme, salt, and pepper. You can also add other seasonings to suit your tastes, such as cumin, coriander, or smoked paprika.

Cooking the Prime Rib at 250 Degrees

Now it’s time to cook your prime rib. Preheat your oven to 250 degrees Fahrenheit. Depending on the size of your prime rib, the cooking time will vary. As a general rule, you should cook your prime rib for about 15-20 minutes per pound.

It’s important to use a meat thermometer to check the internal temperature of the prime rib. The temperature should read 125-130 degrees Fahrenheit for medium-rare, 135-140 degrees Fahrenheit for medium, or 145-150 degrees Fahrenheit for well-done. To get an accurate reading, insert the thermometer into the thickest part of the meat, being careful not to touch the bone.

While the prime rib is cooking, it’s a good idea to rotate it every 30 minutes to ensure even heat distribution. This will also help the meat cook more evenly.

Resting and Carving the Prime Rib

Once your prime rib has reached the desired internal temperature, it’s important to let it rest before carving. This will allow the juices to redistribute throughout the meat, resulting in a more flavorful and tender roast.

Cover the prime rib loosely with foil and let it rest for at least 20-30 minutes before carving. This will also give you enough time to prepare any sides or sauces that you plan to serve with your prime rib.

When it’s time to carve the prime rib, start by removing any twine or butcher’s paper that may be holding the meat together. Then, use a sharp carving knife to make even slices across the grain of the meat. Aim for slices that are about 1/4 to 1/2 inch thick.

As you carve, be sure to remove any excess fat or connective tissue from the meat. This will make for a more enjoyable eating experience and help highlight the flavor of the prime rib. Serve your prime rib slices on a platter with your favorite sides, such as roasted vegetables, mashed potatoes, or a salad.

Serving Suggestions

When it comes to serving your prime rib, there are a variety of options to choose from. Here are a few suggestions:

  • Roasted vegetables: Roasted carrots, brussels sprouts, or green beans make a great side dish for prime rib.
  • Mashed potatoes: Creamy mashed potatoes are a classic accompaniment to prime rib.
  • Horseradish sauce: A tangy and spicy horseradish sauce can help cut through the richness of the prime rib.
  • Au jus: A simple au jus made from beef broth, red wine, and aromatics can add extra flavor to your prime rib.

Of course, these are just a few ideas. Feel free to get creative and experiment with different sides and sauces to find the perfect combination for your tastes.


Cooking prime rib at 250 degrees Fahrenheit can be a great way to achieve a perfectly cooked and juicy roast. By following these tips for choosing the right cut, preparing the meat, and cooking it to the right temperature, you can create a delicious meal that is sure to impress your guests.
