Here’s a recipe for a Perfect Prime Rib Roast—tender, juicy, and full of flavor with a beautifully crusted exterior.


Ingredients (Serves 6–8)

  • 4–6 lbs (1.8–2.7 kg) prime rib roast, bone-in or boneless
  • 4 cloves garlic, minced
  • 2 tbsp olive oil
  • 2 tsp kosher salt
  • 1 tsp black pepper
  • 1 tsp fresh rosemary, chopped (or 1/2 tsp dried)
  • 1 tsp fresh thyme, chopped (or 1/2 tsp dried)

Optional for au jus:

  • 1 cup beef broth
  • 1/2 cup red wine

Instructions

  1. Prep the roast
    • Remove roast from refrigerator 2 hours before cooking to come to room temperature.
    • Preheat oven to 450°F (232°C).
    • In a small bowl, mix garlic, olive oil, salt, pepper, rosemary, and thyme. Rub all over the roast.
  2. Sear the roast
    • Place roast on a rack in a roasting pan, fat side up.
    • Roast at 450°F (232°C) for 15–20 minutes to develop a crust.
  3. Roast to desired doneness
    • Reduce oven temperature to 325°F (163°C).
    • Continue roasting until internal temperature reaches:
      • Rare: 120–125°F (49–52°C)
      • Medium-rare: 130–135°F (54–57°C)
      • Medium: 140–145°F (60–63°C)
    • Use a meat thermometer for accuracy.
  4. Rest the roast
    • Remove roast from oven and tent with foil.
    • Let rest 20–30 minutes to allow juices to redistribute.
  5. Optional au jus
    • Place roasting pan on stove over medium heat.
    • Add beef broth and red wine, scraping up browned bits. Simmer 5 minutes and strain if desired.
  6. Serve
    • Slice against the grain and serve with au jus.

Tips:

  • Bone-in roasts are more flavorful and help retain moisture.
  • For extra crust, season the roast 24 hours in advance and refrigerate uncovered.
  • Use a digital thermometer for precise doneness—prime rib is best medium-rare.

I can also provide a slow-cooker or sous-vide version for an ultra-tender prime rib if you want. Do you want that version?
