The Ultimate Garlic Herb Crusted Prime Rib (Reverse Sear Method)

The Prime Rib Roast (or Standing Rib Roast) is the king of beef cuts. When done correctly, it features a perfectly edge-to-edge pink interior with a salty, garlic-herb crust. This professional guide uses the Reverse Sear method—the secret used by high-end steakhouses to ensure the meat never becomes tough or overcooked.

Why the Reverse Sear?

Uniformity: No “gray ring” of overcooked meat.
Tenderness: Slow-roasting breaks down connective tissue.
The Crust: Searing at the very end ensures the fat is crisp and hot when it hits the table.

Ingredients

The Beef: 3-bone (approx. 6–8 lb) Prime Rib Roast (Bone-in provides better flavor).
The Rub:
- ½ cup unsalted butter, softened.
- 6 cloves garlic, minced.
- 2 tbsp fresh rosemary, finely chopped.
- 1 tbsp fresh thyme, finely chopped.
- 1 tbsp Kosher salt (plus more for dry-brining).
- 1 tsp cracked black pepper.

Step-by-Step Instructions

1. The Professional “Dry Brine” (24 Hours Prior)

For the best flavor, salt your roast 24 hours before cooking. Rub 1–2 tablespoons of Kosher salt all over the meat. Place it on a wire rack over a baking sheet and leave it uncovered in the fridge. This dries the surface for a better crust and seasons the meat to the bone.

2. Slow Roast

Preheat your oven to 120°C (250°F). Slather the softened herb butter rub all over the roast. Place the roast in a roasting pan, bone-side down. Insert a meat thermometer into the thickest part of the beef.

Roast until the internal temperature reaches 48°C (120°F) for Medium-Rare. (This usually takes 20–30 minutes per pound).

3. The Rest (Mandatory)

Remove the roast from the oven and tent it loosely with foil. Let it rest for 30–45 minutes. The temperature will continue to rise to about 52°C (125°F). Do not skip this—resting allows the juices to redistribute.

4. The High-Heat Blast (The Sear)

Increase your oven temperature to 260°C (500°F) or its highest setting. Put the rested roast back in the oven for 6–10 minutes until the exterior is deep brown and sizzling.
