The Ultimate Herb-Crusted Prime Rib Roast

April 13, 2026

A masterclass in roasting: featuring a perfectly seared crust and a tender, juicy center.
Prep time: 20 minutes (plus resting)
Cook time: Approx. 15–20 minutes per pound
Serves: 6–8

Ingredients

1 (5–6 lbs) Bone-in prime rib roast (standing rib roast)
3 tbsp Olive oil (or softened unsalted butter)
4 Garlic cloves, minced
1 tbsp Fresh rosemary, finely chopped
1 tbsp Fresh thyme, finely chopped
2 tsp Smoked paprika
1 tbsp Coarse kosher salt
1 tsp Freshly cracked black pepper

Instructions

1. Temper the Meat (Crucial Step)
Remove the roast from the refrigerator at least 2 hours before cooking. Bringing the meat to room temperature ensures even cooking throughout the entire cut.
2. Prepare the Herb Rub
In a small bowl, combine the olive oil (or butter), minced garlic, rosemary, thyme, paprika, salt, and pepper. Mix until it forms a thick paste.
3. Season the Roast
Pat the roast completely dry with paper towels. Rub the herb paste generously over all sides of the meat. If your roast has a fat cap, score it lightly with a knife so the seasoning can penetrate.
4. The High-Heat Sear
Preheat your oven to 230°C (450°F). Place the roast in a heavy roasting pan, bone-side down. Roast for 15 minutes at this high temperature to create a beautiful, caramelized crust.
5. Low and Slow Roasting
Reduce the oven temperature to 160°C (325°F). Continue roasting until a meat thermometer inserted into the thickest part (avoiding the bone) reaches your desired doneness:
Rare: 48°C (120°F)
Medium-Rare: 54°C (130°F) — Highly recommended
Medium: 60°C (140°F)
6. The Essential Rest
Transfer the roast to a cutting board and tent it loosely with aluminum foil. Let it rest for at least 20–30 minutes.
Why? This allows the juices to redistribute back into the meat. If you cut it too soon, the juices will run out, and the meat will be dry.
Chef’s Tips for Success
The Bone-In Advantage: Cooking with the bone-in provides better flavor and protects the meat from overcooking.
Au Jus: Don't discard the pan drippings! Use them to make a simple red wine reduction or a classic Au Jus to serve alongside the meat.
Slicing: Always slice against the grain for the most tender bite.
