Prime Rib Roast

Prime Rib Roast

Prime rib roast, also known as standing rib roast, is a traditional and luxurious choice for special occasions such as holidays and celebrations because it is an impressive and flavorful cut of meat. Prime rib is made from the ribs of the cow, which are well-marbled with fat, giving the meat a rich and juicy flavor. It is also a relatively large cut of meat, making it perfect for serving a crowd.

In addition to its flavor and size, prime rib is also a relatively easy dish to prepare, as it requires minimal seasoning and can be cooked using a simple roasting method. This makes it a convenient choice for entertaining.

Overall, prime rib roast is a classic and sophisticated choice for special occasions because of its flavor, size, and ease of preparation.

Here are some tips for cooking and serving the perfect prime rib roast:

  1. Choose a good-quality prime rib roast from a reputable source. The roast should be well-marbled and a deep red color.
  2. Allow the roast to come to room temperature before cooking. This will help it cook more evenly.
  3. Preheat the oven to 325°F (165°C).
  4. Place the roast, fat side up, on a rack in a roasting pan, add rock salt to cover bottom. Sprinkle it generously with seasoning salt.
  5. Roast the prime rib until it reaches the desired level of doneness, 1 to 1/2 hours. For medium-rare, cook until the internal temperature reaches 110°F (43°C). For medium, cook until it reaches 135°F (57°C).
  6. Let the roast rest for at least 15 minutes before slicing and serving. Recommend letting the roast stand for 1 hour. This allows the juices to redistribute throughout the meat, making it more tender and flavorful.
  7. Slice the prime rib against the grain into thin slices. Serve with your choice of sides, such as roast potatoes, vegetables, and horseradish sauce.
  8. Enjoy!

  • 7 pounds bone-in beef rib roast — external cap of fat removed
  • 3 tablespoons seasoning salt — to taste
  • 2 pounds rock salt — to cover
  • Before cooking the prime rib bring the beef to room temperature. Usually 2 -3 hours.


  • Preheat the oven to 325°F. In a large roasting pan, add the rock salt to cover bottom of pan. Liberally, season the beef and place in the roaster. Cook the prime rib at 325°F for 1 to 1 1/2 hours or until it reaches an internal temperature of 110°F. Remove from the oven, cover lightly with aluminum foil, and allow to stand for 1 hour or until an internal temperature of 135°F.


NOTES: When cooking prime rib, it is important to allow the large piece of beef to rest to the desired internal temperature. The less done the better. For serving, cooking prime rib allows you serve medium well (end cuts), medium, and medium rare (center cuts) servings of prime rib.
