Measuring spoons
Instant-read meat thermometer
Aluminum foil (optional)
Ingredients
Main Ingredients
1 boneless prime rib roast (about 6 lb)
Seasoning Mixture
10 cloves garlic, minced
2 tablespoons olive oil
2 teaspoons black pepper
2 teaspoons dried thyme
1 teaspoon salt
Optional Ingredients
Fresh rosemary for garnish
Butter for basting
Horseradish or au jus for serving
Instructions
Step 1: Preparation
In a small bowl, combine the minced garlic, olive oil, black pepper, dried thyme, and salt. Pat the prime rib dry with paper towels, then spread the garlic mixture evenly over the entire roast, pressing it gently into the meat.
For best flavor, cover and refrigerate the seasoned roast overnight. This allows the garlic and herbs to deeply penetrate the beef. When ready to cook, remove the roast from the refrigerator and let it sit at room temperature for about 1 hour.
Step 2: Preheating
Preheat the oven to 500°F (260°C). Place the roast fat-side up on a rack set inside a roasting pan to allow even air circulation.
Step 3: Roasting
Roast the prime rib at 500°F for 20 minutes to develop a flavorful crust. Then reduce the oven temperature to 325°F (165°C) and continue roasting for 1 to 1½ hours, or until an instant-read thermometer inserted into the thickest part of the meat registers 130°F for medium-rare.
Step 4: Resting / Finishing
Remove the roast from the oven and loosely tent it with foil. Let it rest for 15 minutes before carving. During this time, the internal temperature will rise to approximately 135°F, and the juices will redistribute for maximum tenderness.
Tips & Notes
Always use a meat thermometer for accurate doneness
Letting the roast rest is essential for juicy slices
For bone-in roasts (9–10 lb), add about 20 minutes to the total cooking time
