Description

Achieve restaurant-quality prime rib at home with this foolproof low-and-slow method followed by a high-heat sear. The result? A tender, juicy roast with a beautifully browned crust. Whether for holidays or a special occasion, this recipe guarantees a perfect prime rib every time!


Ingredients

Scale
  • 1 (6-7 lb) bone-in prime rib roast (about 3 bones)
  • Kosher salt (for seasoning)
  • Black pepper (for seasoning)
  • 4 cloves garlic (minced)
  • 2 tbsp fresh rosemary (chopped)
  • 2 tbsp fresh thyme (chopped)
  • 2 tbsp butter (or olive oil, for crust)
  • Optional horseradish cream (for serving)

Instructions

  1. Prep the Roast: Remove the prime rib from the fridge 2 hours before cooking to ensure even cooking. Pat dry with paper towels.

  2. Season Generously: Mix salt, black pepper, garlic, rosemary, and thyme. Rub all over the roast. Massage butter or olive oil into the meat.

  3. Slow Roast: Preheat oven to 250°F (120°C). Place roast on a wire rack in a roasting pan. Cook for 3 to 4 hours, until the internal temperature reaches 120°F (49°C) for medium-rare.

  4. Rest the Meat: Remove from oven and tent with foil. Rest for 30-40 minutes to let juices redistribute.

  5. Sear for the Perfect Crust: Increase oven to 500°F (260°C). Once preheated, return roast to oven for 5-10 minutes until deep brown.

  6. Slice and Serve: Carve into thick slices and serve immediately.


Notes

  • Use a Meat Thermometer: Ensures perfect doneness.
  • Cooking for Different Doneness:
  • Medium-Rare: 120°F → Rests to 130°F
  • Medium: 130°F → Rests to 140°F
  • Medium-Well: 140°F → Rests to 150°F
  • Make Ahead Tip: Slow-roast ahead of time, then sear just before serving.
