Can You Cook Prime Rib Frozen?

Prime rib is a popular cut of beef, especially during holiday seasons. It’s a delicious and flavorful cut that can be cooked a variety of different ways. But what do you do if you forget to take your prime rib out of the freezer to thaw? Can you cook it from frozen?

The Short Answer?

Yes, you can cook prime rib from frozen, but it’s not recommended. It’s much better to thaw the meat first.

Why Is It Better to Thaw First?

The main reason it’s recommended to thaw your prime rib before cooking is to ensure it cooks evenly. When meat is cooked from frozen, the outside can become overcooked, while the inside remains undercooked. Plus, cooking it from frozen will take longer, which can dry out the meat, making it tougher and less flavorful.

How to Thaw Your Prime Rib

The best way to thaw your prime rib is to let it thaw in the refrigerator for several days. The general rule of thumb is 24 hours of thawing time for every 4-5 pounds of meat. If you’re running short on time, you can also thaw it in cold water. Place the meat in a leak-proof bag and submerge it in cold water. Change the water every 30 minutes until it’s fully thawed. Don’t use warm water, as this can cause bacteria to grow.

Cooking Prime Rib from Frozen

If you’re determined to cook your prime rib from frozen, there are a few steps you can take to ensure the best results:

  • Preheat your oven to at least 325°F
  • Remove any packaging from the meat, and rinse it under cold water
  • Pat the meat dry with paper towels, and season it as desired
  • Place the meat on a rack in a roasting pan, and insert a meat thermometer in the thickest part of the meat
  • Cook until the internal temperature reaches at least 125°F (for medium-rare), or until your desired temperature. This can take between 3-5 hours, depending on the size of the meat


In conclusion, while it is possible to cook prime rib from frozen, it’s not the preferred method. Thawing your meat first ensures even cooking and a more tender, flavorful finished product. However, if you do decide to cook from frozen, make sure you take the necessary steps to minimize the risk of foodborne illness and ensure the best results possible.

It is not unusual for cooks to wonder if they can cook prime rib from a frozen state. After all, owning a large cut of meat like this can often pose a challenge for storage. Yet the answer to whether you can cook it frozen is not as black and white as it may seem.

The primary factor in being able to successfully cook frozen prime rib is the type of cut it is. A rib roast, for example, may cook well frozen, while any other cuts like boneless roasts and rib eyes generally must be thawed before cooking. This is due to the way prime rib is cut and distributed.

In addition to the type of cut, the way it is cooked also matters. If you are roasting your prime rib, it is best to cook it frozen. However, if you are cooking it on a grill, you should generally thaw it before you start. Cooking your prime rib from a frozen state on the grill can cause flare-ups, uneven cooking, and possibly a tough finished product.

It’s important to note that if you cook prime rib from frozen, it will take longer to cook, as the frozen state creates an extended “cold spot” in the middle of the roast. Additionally, food safety protocols dictate that all raw meat products be thawed before cooking. The best methods are to thaw the roast in the refrigerator for one to three days, with a total thawing time depending on the size and weight of the roast, or to microwave thaw for five to eight minutes.

Ultimately, you must weigh a number of variables before cooking prime rib, frozen or otherwise. Consider the type of cut, how it will be cooked, and of course safety guidelines when deciding if you can make this dish successfully from its frozen state. Each of these elements will ultimately determine whether or not cooking frozen prime rib is the right decision for you.
