Prime Rib Roast
Ingredients
The Meat: 3 to 5 kg Prime Rib Roast (Bone-in for more flavor, or boneless for easier slicing).
The Herb Butter Rub:
½ cup unsalted butter (softened at room temperature).
4 to 5 cloves of garlic, minced.
2 tbsp fresh rosemary, finely chopped.
1 tbsp fresh thyme, finely chopped.
2 tbsp coarse sea salt (essential for the crust).
1 tbsp cracked black pepper.
Preparation Steps
1. Preparation (The Golden Rule)
Tempering: Remove the roast from the refrigerator at least 2 hours before cooking. It must reach room temperature to ensure even cooking.
Drying: Pat the meat completely dry with paper towels.
2. Seasoning
In a small bowl, mix the softened butter with garlic, rosemary, thyme, salt, and pepper.
Rub the herb butter mixture all over the roast, focusing heavily on the top fat cap.
3. Roasting Process
The Sear: Preheat your oven to 230°C (450°F). Roast for 15–20 minutes to develop a dark, crispy crust.
Slow Cook: Lower the oven temperature to 160°C (325°F). Continue roasting.
Timing: A general rule is about 30 minutes per kilogram for Medium Rare.
4. Target Internal Temperatures
Use a meat thermometer for the best results:
Rare: 48°C (120°F)
Medium Rare (Recommended): 52°C (130°F) — The temperature will rise about 5 degrees while resting.
5. The Rest (Crucial Step)
Transfer the roast to a carving board and tent it loosely with aluminum foil.
Let it rest for 20–30 minutes. This allows the juices to redistribute, making the meat incredibly tender and juicy.
Pro Tip: Serve your Prime Rib with Au Jus (made from the pan drippings) or a Creamy Horseradish Sauce.
