HOW LONG TO COOK A ROAST BEEF AT 350 RECIPES

Steps:

• Season the prime rib liberally on all sides with salt and black pepper. Sprinkle with the garlic powder and herbs de Provence. Tent the meat loosely with foil, and allow it to stand at room temperature for 1-2 hours.
• Preheat the oven to 350°F with a rack set in the middle.
• Line a roasting pan with heavy-duty aluminum foil and position a flat or V-shaped roasting rack inside of it.
• Set an extra-large skillet over medium-high heat and pour in the olive oil. Once the oil is shimmering, place the prime rib, fat side down, in the skillet. Sear the meat, undisturbed, until browned, 3-4 minutes. Carefully flip the prime rib so it is bone side down, and sear for an additional 2-3 minutes.
• Transfer the prime rib with bone-side down to the middle of the roasting rack.
• Roast the prime rib until it reaches an internal temperature of 80°F, 50-70 minutes, depending on the size of the roast. While the meat is roasting, prepare the vegetables.
• Cut the vegetables into uniform thicknesses. Cut broccoli and cauliflower into large florets. Keep carrots whole and trim all but a couple of inches of the green tops. Cut bell peppers or onions into wedges. Halve Brussels sprouts, etc.
• Place the vegetables in a large mixing bowl. Drizzle with olive oil and season with salt and black pepper. Toss the vegetables with a rubber spatula until they are evenly covered in oil.
• When the prime rib reaches an internal temperature of 80°F, arrange the vegetables on the roasting rack around the meat (or underneath the rack if you'd like them to brown). Continue roasting the prime rib and vegetables until vegetables are tender and slightly charred, and meat reaches an internal temperature of 120-145°F, depending on desired doneness, 30-35 minutes.
• Check to see that prime rib and vegetables are done. Remove from oven or add time as needed.
• Allow the prime rib to rest on the rack for 15-30 minutes, then transfer to a cutting board and untie. Thinly slice the meat from the outside of the roast, then cut the bones away from the rest of the roast meat and slice between them. Carve the rest of the meat into thin slices, and serve the meat and bones immediately with the roasted vegetables. Refrigerate leftovers up to 5 days or freeze up to 6 months.

Steps:

• Remove the roast from refrigerator 1 hour before cooking to reach room temperature. Trim all the fat off the meat. Using a sharp knife, pierce meat about 1/2-inch deep and insert slivers of garlic in each hole, pushing all the way in. Lightly spray the meat with olive oil and season generously with salt, pepper and rosemary. Place the thermometer all the way into the center of the meat.
• Preheat oven to 350F. When the oven reaches 350F, place the roast in a roasting pan and put in the oven.
• Roast until the thermometer reads 130° for rare, 140° for medium rare, 150° for medium, and 155-160° for well done. Remove the roast from the oven and let it rest 10-20 minutes before you cut it so that the juices distributed evenly. I personally remove my roast beef from the oven when it is 135° for medium rare. The temperature will rise an additional 5 degrees as it sits.
• Slice thin and serve.
