Slow Roasted Prime Rib

Slow Roasted Prime Rib is a well-seasoned beef roast with a generous crust created from garlic, fresh herbs, salt, and pepper. Prepared with the bones tied together to retain shape and moisture, the roast is seared at high heat before slow roasting to the preferred doneness. This technique results in tender, flavorful meat with a crisp, browned exterior. Allowing the roast to reach room temperature before cooking promotes even results.

Description

The Slow Roasted Prime Rib recipe uses a 12-pound bone-in prime rib roast seasoned thoroughly with a rub made of olive oil, minced garlic, fresh thyme, rosemary, kosher salt, and black pepper. Tying the ribs together with twine holds the roast's shape and helps it cook evenly while protecting the bones with foil prevents burning.

After resting at room temperature for 30 minutes, the roast is first cooked at a high oven temperature of 500°F for 15 minutes. This initial sear develops a deeply flavored, browned crust. Then the temperature is lowered to 325°F for slow roasting until the internal temperature is five degrees below the desired final temperature, ensuring even doneness throughout.

The bones impart additional flavor and moisture to the meat, making tying the roast with bones in preferable. This prime rib is ideal for special occasions and pairs well with classic sides such as roasted vegetables or mashed potatoes.

Letting the roast rest outside the refrigerator before cooking prevents uneven cooking, improving texture and juiciness.

Ingredients

Servings
  • 12 pounds prime rib roast 6 ribs, bone in
  • 5 tablespoons olive oil
  • 5 cloves garlic minced
  • 4 teaspoons thyme minced, fresh leaves
  • 2 teaspoons rosemary minced, fresh leaves
  • 2 tablespoons salt
  • 1 teaspoon black pepper

Instructions

  1. Preheat the oven to 500 degrees F.
  2. Let your prime rib rest on the counter for 30 minutes. This allows the beef to cook more evenly.
  3. While the prime rib is resting, tie it with twine between each rib. This holds the meat together as it roasts. Wrap the ends of the bones with foil to prevent them from burning.
  4. Make a rub for the prime rib by mixing together the olive oil, garlic, thyme, rosemary, salt and pepper.
  5. Generously coat the prime rib with the olive oil rub.
  6. Place a meat thermometer in the center of the roast. Place the roast on a sheet pan or in a baking dish.
  7. Cook your prime rib at 500 degrees F for 15 minutes to get a browned and flavorful exterior. Watch your roast, if the exterior starts to get too dark for your liking, lower the temperature of the oven to 325 degrees F.
  8. After 15 minutes, reduce the temperature to 325 degrees F. Roast the meat until the thermometer reaches 5 degrees below your ideal temperature.
  9. Remove the prime rib from the oven, cover it in foil and let it rest for 20 minutes.
  10. Cut off the rib bones by holding the bones up vertically and cutting down between the bone and the meat.
  11. Slice and serve the prime rib.

Notes

  • Leaving the bones in during cooking enhances flavor and moisture; tying the ribs helps maintain the roast's shape.
  • Allow the roast to come to room temperature for about 30 minutes before cooking to promote even cooking.
