Bone In Prime Rib Roast Recipe (2024)

FAQs

How many hours does it take to cook a bone-in prime rib? ›

We recommend checking the internal temperature of the roast to determine doneness. To check the degree of doneness, use a meat thermometer and our Measuring Doneness Chart. For a medium-rare Bone-In Prime Rib, cook for 3–3½ hours or until the roast reaches your preferred degree of doneness.

If it is the main course for a sit-down dinner, plan on one pound per person or one rib for every two diners. For example, you can plan on a four-bone roast generously serving eight guests. When in doubt, err on the side of buying too much.

Start by cooking your prime rib at 500°F for 15 minutes and then lower the oven temperature to 325° F and cook for 10-12 min per pound for rare, or 13-14 min per pound for medium rare, or 14-15 min per pound for medium well. A meat thermometer is essential to ensure you cook it perfectly!

Bone-in prime rib roasts are typically more flavorful and cook better than boneless prime rib, but boneless will also work great! If you buy a bone-in prime rib, ask the butcher to cut the bone off and tie it to the roast for you.

In a 325 degree F oven: Medium-rare: 20 to 25 minutes per pound. Medium: 25 to 30 minutes per pound. Medium-well: 30 to 35 minutes per pound.

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.

Here's a rough estimate for roasting prime rib at a temperature of around 325°F (163°C): Rare: 15-17 minutes per pound. Medium Rare: 17-19 minutes per pound. Medium: 19-21 minutes per pound.

Our recommendations: Order a fresh prime rib, not frozen. Order as far in advance as you can, and take delivery at least three days before you plan to serve it, for preparation purposes. If you don't want to remove it yourself, ask for the butcher to remove the chine bone.

How do restaurants make prime rib so tender? The secret to restaurant-style prime rib is cooking the meat super slow at low temperatures. I recommend cooking prime rib at no higher than 200 degrees F. This cooks the meat very slowly, turning the fat into butter and rendering the proteins juicy and soft.

How long to cook a 5 lb prime rib at 350? ›

APPROXIMATE COOKING TIMES for the prime rib cooked at 350°F after the 20 minute cooking time at 450°F. Rare; cook 12-13 minutes per pound or to 130°F. Medium-rare; cook 14-16 minutes per pound or to 140°F (I would not recommend cooking a prime rib any more than medium-rare).

Placing the oven rack too high up will cause your roast to brown too quickly and burn! After 30 minutes in the oven, add a ½ cup of water to the bottom of the roasting pan. The key is to allow the onions to brown and caramelize while roasting, but not to burn and smoke in the fat.

Searing is an important part of roasting a prime rib. Searing the roast first will kill the surface bacteria, which is a nice touch, especially when you are roasting at lower temperatures.

Salt the Prime Rib Overnight

Rub a good quality kosher salt all over the meat the day before you want to cook it. Now, place it in the refrigerator overnight, UNCOVERED in order to enhance the beefy flavor while dissolving some of the proteins, which yields a buttery-tender, juicy roast.

Roast for 20 minutes at 220C/fan 200C/gas 7, then turn the oven down to 160C/fan 140C/gas 3. Cook for 20 minutes per 450g for medium/15 minutes per 450g for rare. Rest the meat for 15-30 minutes in a warm place. Slice the meat neatly away from the bone.

For a medium-rare 5 lb Prime Rib Roast, roast for 1½–2 hours until a meat thermometer inserted in the thickest part of the roast registers 125°F. Remember, your roast will continue to warm after removing it from the oven. Transfer your roast to a carving board and tent loosely with aluminum foil.
