Ingredients
- 1 (5 pound) Prime Rib Roast (Ribeye Roast or Standing Rib Roast)
- 2 Tbsp Olive Oil
- 2 Tbsp Kosher Salt
- 2 Tbsp Coarse Ground Pepper
- 2 tsp Granulated Garlic (or garlic powder)
- Optional: Fresh Rosemary or Thyme (for garnish/flavor)
Instructions (Step-by-Step)
- Bring to Room Temperature (Crucial): Remove the prime rib roast from the refrigerator and place it on the counter to rest for 2 hours before cooking. This ensures the meat cooks more evenly.
- Prep and Season: Preheat the oven to a searing 500°F (260°C). Pour the olive oil over the roast and rub it in on all sides. In a small bowl, combine the Kosher salt, coarse pepper, and granulated garlic. Generously season the roast with this mixture, pressing the spices firmly into the meat.
- The High Sear: Place the seasoned roast on a roasting rack in a roasting pan (or on indirect heat if grilling). Place in the oven for 15–20 minutes at 500°F. This high heat creates the flavorful crust.
- The Low Roast: After 15–20 minutes, lower the temperature of the oven to 300°F (150°C). Continue cooking the roast for approximately 1 to 1 ½ hours, or until the internal temperature reaches 120°F–125°F for medium-rare (see guide below).
- Rest (Mandatory): Carefully remove the roast from the oven or grill and place it on a carving board. Cover the roast loosely with aluminum foil and allow it to rest for 20 minutes before slicing.
- Slice and Serve: Slice the roast against the grain into uniform slices. Serve immediately with horseradish sauce or Au Jus.
Internal Temperature Guide (Remove from Oven at This Temp)
| Desired Doneness | Remove at (Internal Temp) | Final Temp (After Rest) | Cook Time (Estimate) |
| Rare | 120°F (49°C) | 125–130°F (52–54°C) | 12–15 min/lb |
| Medium-Rare (Recommended) | 125°F (52°C) | 130–135°F (54–57°C) | 15–18 min/lb |
| Medium | 135°F (57°C) | 140–145°F (60–63°C) | 18–20 min/lb |
Expert Tips
- Use a Thermometer: This is the most crucial tip for a perfect prime rib roast with garlic. Always use a digital meat thermometer inserted into the thickest part of the meat (avoiding bone and fat).
- Resting Time is Key: The 20-minute rest is non-negotiable. As the meat rests, the internal temperature will continue to rise by 5–10 degrees, and the juices will redistribute, resulting in a much juicier slice of meat.
- Crust vs. Herbs: The competitor recipe uses simple granulated garlic. You can easily elevate this garlic rubbed prime rib by substituting fresh minced garlic for a stronger flavor, or by adding fresh rosemary and thyme to the oil rub.
- Au Jus Option: While not required, you can create a simple Au Jus by adding 1 cup of beef broth to the bottom of the roasting pan before the sear. The drippings will mix with the broth, creating a flavorful base for your sauce.
Variations
- Butter Rub: Substitute the olive oil with 2 tablespoons of softened butter mixed with the garlic and spices for an even richer crust.
- Spicy Kick: Add a half teaspoon of smoked paprika or a pinch of cayenne pepper to the spice rub for a subtle, smoky heat.
- Grilling: If using a grill, ensure the roast is placed over indirect heat during the low-roast phase, keeping the grill temperature steady around 300°F.
Serving Suggestions
Pair this classic holiday roast beef with traditional sides:
- Sauces: Creamy Horseradish Sauce (the classic pairing) and a simple Au Jus made from pan drippings.
- Potatoes: Creamy Mashed Potatoes, Scalloped Potatoes, or Potato Gratin.
- Vegetables: Roasted Garlic Asparagus, Almond Green Beans, or a simple green salad.
Frequently Asked Questions
Q: Do I need to cover the prime rib at any point during cooking?
A: No, for this high-low oven method prime rib, you should leave the roast uncovered for the entire cooking time. Covering the meat traps steam, which will prevent the exterior from developing that desirable crispy, savory crust. Only cover the roast loosely with foil during the 20-minute rest period.
Q: Why do I need to rest the prime rib for so long?
A: Resting the meat is vital for juiciness. If you slice the meat immediately after removing it from the oven, the superheated internal juices will flow out onto the carving board. Resting allows the temperature to stabilize and the juices to be reabsorbed by the muscle fibers, keeping the meat moist.
Q: What is the ideal final temperature for a perfect slice of prime rib?
A: For most people, the ideal final temperature is Medium-Rare, which is 130°F–135°F. You must remove the roast from the oven when the thermometer reads 125°F because the internal temperature will continue to rise as it rests (carry-over cooking).
Q: Can I make this with a boneless roast instead of bone-in?
A: Yes, this method works for a boneless roast as well. Follow the same procedure, but ensure you place the roast on a wire rack inside the pan, as you won’t have the bones acting as a natural rack. Cooking time may be slightly shorter, so monitor the temperature closely.
