Prime Rib Tips

Here is the formula: Multiply the exact weight times 5 minutes. For me it was 5.35 x 5 = 26.75 minutes, which we round up to 27. You'll cook your room-temperature prime rib at 500 degrees F for exactly that many minutes.

Bones have a higher thermal resistance than meat, meaning the meat around the bones will cook slower than the rest of the roast, leaving those sections extra-tender and juicy. To make carving easier, you can remove the bones from the raw beef and tie them back on if you'd like.

Cook Time and Temperature:

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!

Brown the roast at 500°F (or as high as your oven will go) for 15 minutes. Lower the oven to 325°F to finish roasting: Reduce the oven temperature to 325°F. Roast in the oven until the thermometer registers 115°F for rare or 120° for medium rare, and 130°F for medium.

Butchery: Both rib roast and prime are primal cuts of beef; however, prime rib recipes call for the cut to remain whole, whereas a butcher typically divides a rib roast into individual ribeye steaks. The rib roast is generally a boneless cut of meat, while prime rib comes with the bone still in it.

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.

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.
