Bone In Prime Rib Roast Recipe (2024)

FAQs

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

Cook until a thermometer inserted into the thickest part of the prime rib registers 130 degrees F for medium rare, 35 to 45 minutes of cooking time per pound. An 8-pound roast will take about 5 1/2 to 6 hours.

It's no secret that roasts need to cook slow and slow, but for that killer crust on a prime rib the secret is to hit it with a lot of heat first. Like our other prime rib recipes, this rosemary-rubbed prime rib cooks at 450F for 20 minutes before cooking for another 60 to 90 minutes at 350F.

Rule #7: Season Well, and Season in Advance. 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.

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!

Do you cover prime rib roast when cooking? You can cover rib roast when cooking after searing it to help it retain some of its moisture, but it's not necessary. For the best results, leave the roast uncovered until you remove it from the oven or grill and place it at room temperature for resting.

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.

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.

Standing Rib Roast Cook Time Chart (for medium-rare)

6 pounds (bone-in): 20 minutes at 500 degrees F; 70 minutes at 325 degrees F.

You'll cook your room-temperature prime rib at 500 degrees F for exactly that many minutes. (Twenty-seven minutes, in my case.) Then turn off the oven and wait 2 hours without opening the door. When the time's up, remove the prime rib and slice into the most perfectly medium-rare meat you've ever seen.

Step 1: Season Overnight

This is a hefty cut of meat. Because of its density, it requires extra time for the salt in your seasoning to penetrate deep into the roast. The day before you plan to cook, you should generously season it with salt and pepper (and we mean generously).

What is the difference between bone in rib roast and prime rib? ›

Commonly found at steakhouses, rib roasts and prime rib are two of the most luxurious and expensive cuts of beef. Both rib roast and prime rib come from the ribs of the cow, but one difference is that the whole rack of ribs makes up a standing rib roast, while only the ribs near the loin are cut and sold as prime rib.

Rub the prime rib with olive oil. In a small bowl, combine the salt, pepper, herbs and garlic powder. Rub this mixture onto the prime rib. Place the prime rib in a roasting pan, fat-side up, and insert an ovenproof meat thermometer so the tip is centered in the thickest part of the roast.

Place the roast fat side up in a shallow baking pan; then add some basting liquid to the bottom of the pan. I like to use red wine on the bottom of my pan to give the juices even more of a robust flavor, but water or beef stock will work just as well.

Place the seasoned rib roast on a greased roasting rack in a roasting tray. Heat the oven to 250°F with the rack in the lower middle position. Cook for 4 to 5 hours or until the internal temperature in the thickest part of the roast is 125-130°F for medium-rare prime rib, or 135-140°F for medium.

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 the best results, leave your prime rib roast out on the counter to come up to room temperature for two to three hours before cooking. It's not advisable to leave it much longer than three hours to help prevent the development of bacteria.
