Best Prime Rib Roast Recipe
Description
The Best Prime Rib Roast Recipe starts by tying a 4-6 pound rib roast to maintain shape during cooking. A robust seasoning paste made with garlic, parsley, oregano, black pepper, kosher salt, rosemary, thyme, onion and garlic powders, celery seed, Dijon mustard, and olive oil is applied all over the roast. The searing step at 475°F creates a caramelized crust that locks in juices, while subsequent roasting at 325°F cooks the roast evenly to rare, medium rare, or medium well.
This roast produces a moist and tender prime rib with an herbaceous flavor profile and a savory crust. Optional vegetables placed in the roasting pan can enrich pan drippings for au jus. The method encourages monitoring internal temperature to achieve perfect doneness for each slice.
Serve the prime rib sliced, ideally with horseradish cream sauce or au jus made from pan drippings. It’s suitable for holiday meals or special gatherings due to its impressive presentation and flavor.
For smaller roasts, an Instant Pot or cast iron skillet with rack can be used. Leftover prime rib can be reheated slice-by-slice. Doneness is best judged by internal temperature: rare (120-130°F), medium rare (130-135°F), medium (135-145°F), medium well (145-155°F), and well done (155°F+).
Ingredients
- 4-6 pound rib roast dabbed dry with paper towels, bone-in or boneless
- 4 garlic pressed or grated, cloves
- 1 tablespoon parsley dried
- 1 tablespoon oregano dried
- 1 tablespoon black pepper , freshly ground
- 1 tablespoon kosher salt coarse
- 2 teaspoons rosemary dried
- 2 teaspoons thyme dried
- 1 teaspoon onion powder
- 1 teaspoon garlic powder
- 1/2 teaspoon celery seed
- 2 tablespoons Dijon mustard
- 1 tablespoons extra virgin olive oil
- onion optional, or carrots or celery
- carrot
- celery
- Horseradish cream sauce
Instructions
- Tie the roast with cooking twine at 2 inch increments. Preheat the oven to 475°F. Prepare a wire rack or broiler pan for the roast. *
- In a small bowl, stir together the garlic, parsley, oregano, pepper, salt, rosemary, thyme, onion powder, garlic powder and celery seed. Set aside.
- In another small bowl, whisk together the olive oil and mustard. Using a spatula or clean hands, smother this mixture onto the roast. Pat the dry herb mixture into the wet mixture so it sticks. Set aside for 15 minutes.
- If you want to season the drippings for an au jus, adding an onion, carrots and celery to the bottom of the roasting pan will help give it flavor while it cooks. This is optional and only needed if you plan to make an au jus sauce.
- Sear the roast at 475°F for 15 minutes. Then lower the oven temperature to 325°F and cook for 10-12 min per pound for rare prime rib, or 13-14 min per pound for medium rare prime rib, or 14-15 min per pound for medium well prime rib. Check the temperature using a digital thermometer.
- Remove the roast, tent with aluminum foil and allow to rest for 30 minutes.
- Place the roast on a cutting board and slice into 2-inch slices. Serve with your favorite sauce or compound butter (listed in the post!).

Notes
- Use a roasting rack or wire rack to elevate the roast for even heat circulation.
- Let the seasoned roast rest at room temperature for 15 minutes before cooking for better seasoning absorption.
- Optional root vegetables like onions, carrots, and celery can be added under the roast to flavor pan drippings for au jus.
- For precise doneness, use a meat thermometer to monitor internal temperature during cooking.
- If guests prefer different doneness levels, carve the roast and reheat individual slices in the oven.
- The recipe works well with bone-in or boneless rib roasts between 4-6 pounds.
