Prime Rib

1 . Stage

Salt the roast and let sit at room temp: Remove the beef roast from the refrigerator 3 hours before you start to cook it. Sprinkle it with salt all over and let it sit, loosely wrapped in butcher paper. Roasts should be brought close to room temperature before they go into the oven to ensure more even cooking.

2 . Stage

Tie with kitchen string: If your butcher hasn't already done so, cut the bones away from the roast and tie them back on to the roast with kitchen string. This will make it much easier to carve the roast, while still allowing you to stand the roast on the rib bones while cooking.

3 . Stage

Preheat the oven and season the roast: Preheat your oven to 500°F (or the highest temp your oven reaches, if it's less than 500°F). Pat the roast dry with paper towels (pre-salting should have made the roast release some moisture), and sprinkle the roast all over with salt and pepper.

4 . Stage

Place the roast fat-side-up in a roasting pan: Insert an ovenproof meat thermometer into the thickest part of the roast, making sure that the thermometer isn't touching a bone. There are so many variables involved that affect cooking time, this is why you should use a meat thermometer . A prime rib roast is too expensive to "wing it". Err on the rare side, you can always put the roast back in the oven to cook it a bit longer, if it's too rare for your tastes.

5 . Stage

Brown the roast at high temperature: Brown the roast at 500°F (or as high as your oven will go) for 15 minutes.

6 . Stage

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. To estimate the total cooking time, allow about 11 to 12 minutes per pound for rare and 13 to 15 minutes per pound for medium rare. The actual cooking time will depend on the shape of the roast, how chilled your roast still is when it goes into the oven, and your particular oven. A flatter roast will cook more quickly than a thicker one. A chilled roast will take more time than one closer to room temp. Check the temperature of the roast using a meat thermometer an hour before you expect the roast to be done. For example, with a 10 pound roast, you would expect 2 hours of total cooking time for rare (15 minutes at 500° and 1 3/4 hours at 325°). In this case, check after 1 hour 15 minutes of total cooking time, or 1 hour after you lowered the oven temp to 325°. (A benefit of using a remote thermometer is that you don't have to keep checking the roast, you'll be able to see exactly what the temperature is by looking at the thermometer outside of the oven.)

7 . Stage

Let the roast rest: Once the roast has reached the temperature you want, remove it from the oven and place it on a carving board. Cover it with foil and let it rest for 15 to 30 minutes before carving. The internal temperature of the roast will continue to rise while the roast is resting.

8 . Stage

Slice the roast: Cut away the strings that were used to hold the roast to the rack of rib bones. Remove the bones (you can save them to make stock for soup later.) Then, using a sharp carving knife, slice meat across the grain for serving, making the slices about 1/2-inch to 3/4-inch thick.

9 . Stage

Make the gravy: To make the gravy , remove the roast from the pan. Remove excess fat, leaving 1/4 cup of fat plus the browned drippings and meat juices in the roasting pan. Place the roasting pan on the stovetop on medium high heat. Use a metal spatula to scrape up drippings that might be sticking to the pan. When the fat is bubbly, sprinkle 1/4 cup of flour over the fat and drippings in the pan. Stir with a wire whisk to incorporate the flour into the fat. Let the flour brown (more flavor that way and you don't have the taste of raw flour in your gravy.) Slowly add 3 to 4 cups of water, milk, stock, or beer to the gravy. Continue to cook slowly and whisk constantly, breaking up any flour lumps. The gravy will simmer and thicken, resulting in about 2 cups of gravy. Season the gravy with salt and pepper and herbs to taste. Did you love the recipe? Give us some stars and leave a comment below!
