Instructions

Remove the prime rib from the refrigerator at least one hour before cooking to bring it to room temperature. Pat dry with paper towels.
Preheat the oven to 450°F (230°C) and position the oven rack in the center.
In a small bowl, combine minced garlic, chopped thyme, salt, pepper, olive oil, and Dijon mustard to form a smooth paste.
Rub the herb mixture evenly over the entire surface of the roast, pressing gently to adhere.
Place the roast on a roasting rack set in a shallow roasting pan, fat side up, and insert a meat thermometer into the thickest part, avoiding the bone.
Roast at 450°F (230°C) for 20 minutes to form a flavorful crust.
Reduce the oven temperature to 325°F (165°C) and continue roasting until the internal temperature reaches 120°F (49°C) for rare, 130°F (54°C) for medium-rare, or 140°F (60°C) for medium, usually 1.5–2 hours depending on roast size.
Remove from oven, cover loosely with aluminum foil, and let rest for 20–30 minutes.
Slice the roast against the grain into thick, juicy pieces. Garnish with rosemary sprigs if desired and serve immediately.

Notes

Bring the roast to room temperature for even cooking.
Use a meat thermometer to monitor doneness precisely.
Resting the roast before slicing ensures it stays juicy.
Adjust seasoning to taste and optionally sear in a hot skillet before roasting for extra crust.
