Ingredients
Scale
Prime Rib Roast
- 1 bone-in prime rib roast (adjust size based on servings)
Seasonings and Aromatics
- 1/3 medium onion per pound (large dice or thickly sliced; up to 4-5 onions total)
- 1 teaspoon Kosher or coarse sea salt per pound
- ½ teaspoon freshly ground black pepper per pound
- 1 teaspoon minced garlic per pound
- 1 teaspoon fresh rosemary per pound, minced
- 1 teaspoon fresh thyme per pound, minced
- ½ teaspoon olive oil per pound
Instructions
- Prepare the Oven and Roast: Preheat your oven to a low temperature to allow slow roasting, which ensures even cooking. Position the oven rack in the lower third of the oven for optimal heat circulation.
- Season the Prime Rib: In a bowl, combine the minced garlic, fresh rosemary, thyme, salt, pepper, and olive oil. Rub this herb mixture evenly all over the surface of the prime rib roast to coat thoroughly.
- Arrange Onions: Spread the diced or thickly sliced onions in a roasting pan. These will add flavor and moisture to the roast as it cooks while catching the drippings for a flavorful pan sauce or gravy.
- Place the Roast: Set the seasoned prime rib on top of the onions in the roasting pan with the bone side down. This positioning helps keep the meat juicy and flavorful.
- Slow Roast: Insert a meat thermometer into the thickest part of the roast without touching the bone. Roast in the oven at a low temperature for approximately 3 to 4 hours, or about 25 minutes per pound, until the internal temperature reaches your desired doneness (e.g., 120°F for rare, 130°F for medium-rare).
- Rest the Meat: Remove the roast from the oven and tent it loosely with foil. Allow it to rest for at least 20 minutes so the juices redistribute throughout the meat, enhancing tenderness and flavor.
- Carve and Serve: Slice the prime rib between the bones for thick, juicy cuts. Serve immediately with your favorite sides and the onions from the pan if desired.
