Equipment

  • bowl
  • pan

Ingredients

  • Prime rib roast 4-6 pounds
  • Olive oil 1/4 cup
  • Garlic 3 cloves, minced
  • Fresh rosemary 2 tbsp, minced
  • thyme 2 tbsp, minced
  • Smoked paprika 1 tsp
  • Salt 1 tsp
  • freshly ground black pepper 1/2 tsp
  • Red wine 1/4 cup
  • Worcestershire sauce 1/4 cup

Instructions

STEP 1

  • Preheat your oven to 450°F (230°C).
  • In a small bowl, mix together the extra-virgin olive oil, finely chopped garlic, fragrant rosemary, chopped thyme leaves, smoky paprika, sea salt, and cracked black pepper to create a paste.

STEP 2

  • Rub this flavorful paste generously over the surface of the ribeye roast, ensuring it’s evenly coated on all sides.

STEP 3

  • Place the roast on a rack in a roasting pan with the fat side up. Insert a meat thermometer into the thickest part of the roast, ensuring it’s not touching bone.
  • Roast the meat in the preheated oven for 20 minutes to sear the outside and lock in juices.

STEP 4

  • Reduce the oven temperature to 325°F (160°C) and continue roasting. Estimate about 15-20 minutes per pound for medium-rare or until the thermometer reads your desired doneness: 135°F (57°C) for medium-rare, 145°F (63°C) for medium.
  • While the roast is cooking, in a separate bowl, combine the rich red wine and savory Worcestershire sauce.

STEP 5

  • About halfway through the cooking time, baste the roast with this wine and Worcestershire mixture to keep it moist and add depth to the flavors.

STEP 6

  • Once the roast reaches your desired doneness, remove it from the oven and tent it loosely with foil. Let it rest for at least 15-20 minutes to allow the juices to redistribute.
  • Slice the ribeye roast against the grain into thick, succulent portions and serve, impressing everyone with your delicious, uniquely flavored prime rib!
  • Enjoy your culinary masterpiece!
