Ingredients
-
1 (5–7 pound) prime rib roast, bone-in or boneless
-
3 tablespoons Dijon mustard
-
4 cloves garlic, minced
-
2 tablespoons fresh rosemary, finely chopped
-
1 tablespoon fresh thyme, finely chopped
-
2 teaspoons salt
-
1 teaspoon freshly ground black pepper
-
2 tablespoons olive oil
-
1 cup beef broth or water (for roasting pan)
Instructions
-
Remove the prime rib from the refrigerator at least 2 hours before cooking to bring it to room temperature.
-
Preheat the oven to 450°F (230°C) and position the oven rack in the lower-middle section.
-
In a small bowl, combine Dijon mustard, minced garlic, rosemary, thyme, salt, pepper, and olive oil to form a smooth paste.
-
Pat the roast dry with paper towels and rub the herb-Dijon mixture generously over the entire surface.
-
Place the roast on a rack in a roasting pan and pour beef broth or water into the bottom of the pan.
-
Roast at 450°F (230°C) for 20–25 minutes to create a golden-brown crust.
-
Reduce the oven temperature to 325°F (165°C) and continue roasting until the internal temperature reaches your desired doneness (Rare: 120–125°F, Medium-Rare: 130–135°F, Medium: 140–145°F).
-
Remove the roast from the oven and tent loosely with foil. Let it rest for 20–30 minutes.
-
Carve against the grain into desired thickness and serve with your favorite sides.
Notes
-
Bring the roast to room temperature for even cooking.
-
Use a meat thermometer for accuracy.
-
Let the roast rest to lock in juices.
-
Substitute dried herbs if fresh are unavailable (use 1 tsp dried rosemary and ½ tsp dried thyme).
-
Leftovers can be refrigerated for 3–4 days or frozen for up to 2 months.
-
Tent loosely with foil while resting to maintain a crisp crust.
