Roast in 450 degree oven for 20 minutes, then reduce heat to 350 degrees and continue cooking until the internal temperature reaches 115 to 120°F for medium rare (125 to 130°F after resting), or 125 to 130°F for medium (135 to 140°F after resting). And remember, a roast will continue to rise by 5 to 10°F as it rests.
Refrigerating the roast uncovered allows the surface to dry a little bit, which helps in browning, while leaving the meat inside juicy and tender. Step 3: Retrieve the roast from the refrigerator and set it out, lightly covered with foil, two hours before you plan to cook it.
When checking the temperature of your prime rib roast, insert meat thermometer so tip is in thickest part of beef, not resting in fat or touching bone. Cook until rib roast reaches an internal temperature of 120 degrees F. (or your desired temperature).
Alton Brown of Good Eats on the FoodNetwork likes the idea of aging single steaks and instructs us to “Wrap the steak in a single layer of paper towels and put on a cooling rack set inside a half sheet pan. Refrigerate 24 hours. Discard the paper towels, rewrap and return to the refrigerator, on the rack, for 3 days.
For cooking instructions for prime rib roast that is boneless the basic cooking time is for medium is a 3 to 4 pound prime rib roast should be cooked at 350 degrees Fahrenheit for 23 to 30 minutes per pound, for a 4 to 6 pound prime rib roast you should cook it at 350 degrees Fahrenheit for 18 to 20 minutes per pound

Plan 35 minutes per pound at 225 degrees F for smoking a rare roast. 40 minutes per pound at 225 degrees F for smoking a medium roast. Don't forget to allow at least 30 minutes of rest time and another 15 minutes or so for the high heat sear before serving.
Do not add water or liquid and do not cover the roast. Covering the roast would result in more steaming than roasting in the oven so we cook a beef roast uncovered. Ideally, the roasting pan sides should be 2 to 3 inches high. If you don't have a roasting pan, place an oven-safe wire rack inside a 13x9-inch baking pan.
For best results, salt your prime rib on all surfaces with kosher salt at least 45 minutes before you start cooking it, and preferably the day before, leaving it in the fridge uncovered overnight. Your meat ends up better seasoned with less salty run-off.
Preheat the oven to 250 degrees. Roast for about 25 minutes per pound of meat. Check the temperature 30 minutes early. You want 130° for medium-rare.
Cook the RibPlace the roast fat side up, bone side down, in a large roasting pan. Cook for 15 minutes, then reduce the oven temperature to 325°F. This allows the heat to sear the roast, trapping the juicy flavors inside while the rest of the meat cooks.

| 6–7 adults | 7 lb. (3-4 bones) | 6 lb. |
Place the roast, fat side up, into the convection oven set at the highest temperature (around 450°F.) for 15 minutes, then lower the temperature to 325°F., check and baste it every 1/2 hour. Cook and Remove: Check the roast with an internal meat thermometer about 1/2 hour before the estimated end of the roasting time.
Prime rib is at its best cooked rare or medium rare — it should not be cooked past medium (140°F) or all the fat will melt out of the meat, leaving it tough, dry, and chewy. After the prime rib is cooked, make sure to let it rest for 30 minutes for the meat to reabsorb all the delicious juices before carving.
On the roast, rub the garlic, then the salt and pepper and place it, fat side up, in an uncovered pan. Sear in a very hot oven (450-475 degrees) for 30 minutes, reduce heat to 300 degrees, and cook as follows: Rare- 18-20 minutes per pound, Medium- 25 minutes per pound, Well done- 30 minutes per pound.
What's the Best Cut of Prime Rib? The first cut (sometimes labeled the small end or the loin end) comes from the hind of the standing rib roast near the loin. It's more expensive and generally regarded as the best cut because it has less connective tissue than the second cut and therefore is more tender.
The prime rib is naturally higher in price because it is considered a better cut of meat. It is a principle of economics and money that the more desirable items are going to cost more money. As the demand for the product increases, the price will also increase.
What is Prime Rib? At the store, “Prime Rib Roast†can go by different names including Rib Roast, or Standing Rib Roast (because it is positioned standing on the rib bones as it roasts). It can be found in the meat case with both boneless and bone-in options.
Steps
- Heat oven to 350°F. Arrange roast and all vegetables in ungreased 13x9-inch (3-quart) baking dish. Sprinkle with all remaining ingredients except water. Pour water over top. Cover with foil.
- Bake at 350°F. for 2 to 2 1/2 hours or until beef and vegetables are tender. Serve with pan juices.
For rare ribeye roast, the in-oven temperature should be 105-110 degrees. For medium rare to medium ribeye roast, the in-oven temperature should be 120 to 125 degrees Fahrenheit. For well done ribeye roast, the in-oven temperature should be 130 to 135 degrees Fahrenheit.
Sear Roast Method
- Preheat oven to 300°F.
- If desired, lightly oil and season* meat prior to cooking.
- Carefully place meat in pan and sear for 2-3 minutes on first side or until well browned.
- For roasts, sear all sides, then place on rack in roasting pan.
- Test doneness of meat by using a kitchen thermometer.
Check the temperature of the roast using a meat thermometer an hour before you expect the roast to be done. For example, with a 10 pound roast, you would expect 2 hours of total cooking time for rare (15 minutes at 500° and 1 3/4 hours at 325°).
In order to get the most flavor out of your beef, whether it is for a roast or for a stew, you must first sear it. When you pan sear beef, you quickly cook the outer surface of the meat at a high temperatures so that it caramelizes and forms a crust.
The USDA recommends steaks and roasts be cooked to 145°F (medium) and then rested for at least 3 minutes. To ensure food safety, ground beef should be cooked to a minimum 160°F (well done). Be sure to check with a thermometer, as color alone is not a foolproof indicator.
