Description

A gourmet centerpiece for any special occasion, this Garlic Herb Prime Rib Roast features a succulent, tender interior enveloped by a flavorful herb-crusted exterior. Juicy, impressive, and surprisingly easy to prepare, it elevates any gathering.


Ingredients

Scale
  • 1 prime rib roast (34 ribs, bone-in or boneless)
  • 46 garlic cloves, minced
  • 2 tbsp fresh rosemary, chopped
  • 2 tbsp fresh thyme, chopped
  • 23 tbsp olive oil or softened butter
  • Salt and freshly ground black pepper to taste

Instructions

  1. Combine garlic, rosemary, thyme, olive oil (or butter), salt, and pepper. Rub all over the roast. Wrap and refrigerate uncovered for up to 24 hours for deeper flavor and a crispier crust.
  2. Remove roast from fridge 2 hours before cooking to bring to room temperature.
  3. Preheat oven to 135°C (275°F). Place roast bone-side down or fat-side up on a rack in a roasting pan. Insert oven-safe thermometer if available. Roast until internal temperature reaches 48°C (118°F) for medium-rare, about 2–2½ hours.
  4. Remove from oven and tent loosely with foil. Rest for 30 minutes. Increase oven temperature to 260°C (500°F).
  5. Return roast to oven for 10–12 minutes until a deep golden crust forms and internal temperature reaches 52–55°C (125–130°F) for medium-rare. Rest for 20 minutes before slicing.
  6. Slice and serve with desired sides and sauces.

Notes

  • Rub and refrigerate the roast the night before for enhanced flavor.
  • Use a meat thermometer for accurate doneness.
  • Resting before and after searing helps retain juices.
  • Reverse searing creates a perfect crust without overcooking the center.
  • Pair with horseradish sauce, au jus, or creamy mustard sauce.
