🥩 Perfect Prime Rib Roast

Serves: Varies by size (estimate ½–¾ lb per person with bone, 1 lb per person boneless)

Prep Time: 10 minutes

Cook Time: Depends on roast size (see chart below)

Rest Time: 20–30 minutes

Total Time: Varies

🌿 Ingredients

  • 1 prime rib roast (bone-in or boneless, any size — typically 4–8 lbs)
  • 1–2 tbsp olive oil (optional)
  • 2 tsp garlic powder
  • 1–2 tbsp kosher salt
  • 1 tsp freshly ground black pepper
  • Optional extras:
    • Fresh rosemary and thyme (for aroma)
    • 3–4 cloves garlic, minced, for extra flavor

🔥 Directions

1. Prepare the roast

  1. Remove your prime rib from the refrigerator at least 2 hours before cooking so it can come to room temperature — this ensures even cooking.
  2. Pat it completely dry with paper towels.
  3. Rub the entire roast with olive oil (if using).
  4. Season generously with salt, pepper, and garlic powder on all sides.
    • Optional: Press in chopped garlic and fresh herbs for added flavor.

2. Preheat the oven

  • Preheat your oven to 450°F (230°C).
  • Place the roast fat side up on a rack in a roasting pan (this helps the fat baste the meat as it cooks).

3. Sear and roast

  1. Roast at 450°F (230°C) for 15 minutes to create a flavorful crust.
  2. Without opening the oven door, reduce the temperature to 325°F (165°C).
  3. Continue roasting according to your preferred doneness: Doneness Internal Temp Approx. Cook Time* Rare 120–125°F (49–52°C) 15–17 min/lb Medium Rare 130–135°F (54–57°C) 17–19 min/lb Medium 135–140°F (57–60°C) 20–22 min/lb Medium Well 145°F (63°C) 23–25 min/lb *Use a meat thermometer inserted into the thickest part of the roast (avoid bone).

4. Rest before slicing

  • When the roast reaches your target temperature, remove it from the oven and tent loosely with foil.
  • Let rest for 20–30 minutes before slicing — this allows the juices to redistribute, keeping the meat tender and moist.

✅ The roast will continue to rise about 5°F while resting — so pull it a bit early if you prefer a specific doneness.

5. Carve and serve

  • Slice against the grain into thick or thin slices, depending on preference.
  • Serve with au jus, horseradish cream, or a simple pan gravy.

🍽️ Serving Suggestions

  • Pair with garlic mashed potatoes, Yorkshire pudding, or roasted vegetables.
  • Add a drizzle of herb butter or red wine reduction for restaurant-quality flavor.

💡 Tips for Perfect Prime Rib

  • Room temperature meat = even cooking — don’t skip this step.
  • Always rest the roast before cutting — it’s the key to juicy results.
  • Save the drippings for a quick au jus:
    • Skim off fat, add a splash of beef broth, and simmer for 2–3 minutes to create a rich, savory sauce.
  • For extra crisp crust: finish under the broiler for 2 minutes before resting.
