The Closed-Oven Method for Cooking a Prime Rib Roast (2024)

FAQs

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!

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.

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.

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.

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.

It takes approximately 35 minutes per pound to smoke prime rib to Rare doneness with the smoker running steady at 225 degrees F. If you like your prime rib closer to Medium doneness, plan on 40 minutes per pound at 225 degrees F.

Should you put water in the bottom of the roasting pan when cooking prime rib? ›

This will allow the meat to cook more evenly. Preheat the oven to 450°F. Pour 1-2 cups of water or beef broth in the bottom of a roasting pan. As the fat from the roast drips into the pan as it cooks, this will prevent it from burning in the bottom of the pan.

Pull the rib roast out of the fridge and let temper on the counter for three hours. USDA guidelines requires food not be held above 33°F (1°C) for more than 4 hours. A three-hour rest on the counter is well within time constraints.

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.

If you don't have a meat thermometer, a general rule of thumb is to first cook the prime rib at 500 F for 20 minutes, then cooking it at a reduced heat of 325 F at 20 minutes per pound of meat – for the 5 pound Prime Rib that this recipe calls for, at a medium rare cook, that would be 1 hour of cook time.

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.

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.

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