What is the trick to cooking prime rib? ›

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.

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.

The Benefits of Slow Roasting

First, slow roasting produces a Prime Rib that is tender, juicy, and has evenly cooked meat.

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.

We recommend a low, slow cook preceded by a good sear.

Let it sit on the counter for 4 hours before cooking. Bringing the roast to room temperature is especially important here because a cold roast will take much longer to cook. Step three: Cook it low and slow. Set the oven to 225 degrees F and put the roast in the oven.

Place 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. On average, each pound of rib needs 15 minutes to cook (i.e., a 4 lb.

How long to cook an 8 lb prime rib at 325 degrees? ›

7 pounds (bone-in): 20 minutes at 500 degrees F; 85 minutes at 325 degrees F. 8 pounds (bone-in): 20 minutes at 500 degrees F; 100 minutes at 325 degrees F.

If you're using one of the traditional methods with a probe thermometer, simply leave the probe in after you take the meat out of the oven.

For a bone-in prime rib, figure two servings per rib, while a boneless roast will yield two servings per pound. When trying to figure out how much time you need to roast your prime rib, use this simple calculation: weight of the prime rib (in pounds) x 5 = total roasting time in minutes.

Let it sit on the counter for 2 to 3 hours before smoking; this will help it cook more evenly.
