Best 5 Unattended Prime Rib Roast Recipes

BEST NO-FAIL PRIME RIB (GARLIC HERB CRUST)

Steps:

• Remove the prime rib from the fridge 2-3 hours before cooking, and allow it to come to room temperature.
• Preheat your oven to 450F/230C. In a small bowl, mix together the butter, garlic, salt, thyme, rosemary, and black pepper.
• After the prime rib has come to room temperature, pat it down with paper towels to make sure it's dry. Then rub the entire outside of the prime rib with the herb butter mixture.
• Place the prime rib in an oven-safe pan or roasting tray with the bones-side down, fat-side up. Place the onion slices in the pan around the meat, if you're making the red wine au jus. If not, you can omit the onions.
• Cook the prime rib in the center of the oven for 20 minutes at 450F. It should get a nice sear on the outside. If not, cook it a few minutes longer. Then reduce the temperature of the oven to 325F and continue cooking until the internal temperature reaches 120F (about an hour and a half), for medium-rare. But go by temperature, not time, as it will depend on the size of your prime rib and your oven.
• Remove the prime rib from the oven and let it rest for 20-30 minutes. You can tent it with aluminum foil to keep it warm. Then, remove the string and bones, and slice it up into thick 1/2" slices.
• After you've removed the fat from the pan, add up to 1/4 cup of drippings back in along with the beef broth and red wine. If you have leftover herbs, you can toss those in as well.
• Simmer this for about 15 minutes, or until the liquid has reduced by half. It's meant to be a thin sauce, but if you'd like to add a little bit of a thickener, you can do that as well. Strain the au jus to remove the onion and any browned bits, then drizzle over the prime rib.

THE PERFECT PRIME RIB ROAST

Steps:

• Preheat oven to 375 degrees F (190 degrees C). Place a rack inside a roasting pan.
• Mix garlic powder, onion powder, dill weed, pepper, and salt together in a bowl; rub onto roast, including the ribs. Place roast, rib-side down, onto rack in roasting pan.
• Bake roast in the preheated oven for 45 minutes. Turn off oven, keeping the door closed the entire time, and keep roast in oven for 3 hours. Turn oven back to 375 degrees F (190 degrees C) and cook roast until an internal temperature of 145 degrees F (65 degrees C) is reached, 30 minutes more.

PRIME RIB ROAST

Steps:

• Remove the roast from the refrigerator 2 or 3 hours before cooking.
• Preheat oven to 450.
• Rub butter on the cut ends of the roast.
• Combine flour, salt and pepper together in a small bowl, and then massage the mixture all over the meat.
• Set the roast, rib side down, in a shallow roasting pan (the ribs act as a natural rack), and place in the oven. Roast for approximately 20 to 30 minutes, or until the roast is nicely darkened. Reduce oven to 350 and continue to roast, basting every 15 or 20 minutes, until the roast reaches an internal temperature of 125 degrees (for medium-rare) on an instant-read thermometer. Remove the roast to a cutting board and let rest for 20 minutes before carving into either huge slabs or off the bone entirely and then thin slices.

PRIME RIB

Steps:

• Liberally season the prime rib with the salt and some pepper and refrigerate overnight.
• An hour before cooking, remove the roast from the refrigerator to allow it to come to room temperature.
• Meanwhile, preheat the oven to 400 degrees F.
• Put the reserved ribs in a roasting pan bowed-side up (the ribs will be acting as the roasting rack). Scatter any fat and meat trimmings in the pan around the bones. Roast the bones and trimmings for about 30 minutes, or until the fat starts to render.
• Remove the pan from the oven, put the rosemary sprigs on top of the bones, then top with the prime rib. Put the smashed garlic in the bottom of the pan with the trimmings. Baste the beef with the fat drippings and return the pan to the oven.
• Cook for 30 minutes and then baste the roast again.
• Reduce the heat to 350 degrees F and cook until the meat is medium rare (an internal temperature of 125 degrees F to 130 degrees F), about 1 hour, 15 minutes, basting the roast every 30 minutes until it is done. Keep in mind that the roast will continue to cook while resting.
• Remove the roast from the oven and put it on a cutting board to rest, uncovered, for 20 minutes. Slice the prime rib to the desired thickness and garnish with the arugula and olive oil.
