Ingredients

For the Prime Rib:
* 1 (4-5 bone) prime rib roast (8-10 lbs), bone-in, fat cap trimmed to 1/4 inch
* 2 tbsp extra virgin olive oil
* 2 tbsp coarse kosher salt
* 1 tbsp black pepper
* 1 tbsp garlic powder
* 1 tbsp onion powder
* 1 tsp crushed dried rosemary
* 1 tsp dried thyme
For the Truffle Au Jus:
* 2 cups high-quality beef broth
* 1 cup red wine (Merlot/Cabernet Sauvignon)
* 1 finely minced shallot
* 2 smashed garlic cloves
* 1 sprig fresh thyme
* 1 bay leaf
* 1 tbsp unsalted butter
* 1-2 tsp black truffle oil (to taste)
* Salt and pepper to taste
Step-by-Step Instructions

1. Prepare & Brine: Two days prior, pat prime rib dry. Rub with combined salt, pepper, garlic, onion, rosemary, thyme. Place uncovered on wire rack over baking sheet. Refrigerate 48 hours for enhanced flavor and crust.
2. Temp & Preheat: Roasting day: remove prime rib 3-4 hours before cooking. Preheat oven to 450°F (230°C).
3. Sear & Roast: Drizzle roast with olive oil. Place fat-side up in roasting pan. Sear in 450°F oven 20-25 minutes until deep brown crust. Reduce oven to 275°F (135°C). Insert meat thermometer into thickest part (avoid bone). Roast 2-3 hours, targeting 120-125°F (rare) or 130-135°F (medium-rare).
4. Rest: Critical for tenderness. Remove roast, transfer to cutting board, tent with foil. Rest 30-45 minutes; internal temperature will rise.
5. Truffle Au Jus: While meat rests, drain pan fat (keep drippings). Over medium-high heat, sauté shallot (2-3 min), then garlic, thyme, bay leaf (1 min). Deglaze with red wine, reduce by half (5 min). Add beef broth, simmer 10-15 minutes. Strain. Whisk in butter, then truffle oil just before serving. Season.
6. Carve & Serve: Carve rested prime rib against grain into thick slices. Serve immediately with warm Au Jus.
Expert Tips
* Thermometer is Key: A digital meat thermometer is your best friend for perfect prime rib. No guessing!
* Resting is a Must: Don’t carve early. Resting redistributes juices, ensuring tender, moist slices.
* Carve Smart: Use a sharp knife. Slice against the grain for maximum tenderness.
* Quality First: For this dish, high-quality roast, broth, truffle oil significantly impact flavor. Choose well.
Variations
For aromatic changes, add fresh rosemary sprigs and garlic cloves to the roasting pan during the last hour. If truffle oil isn’t preferred, a rich mushroom au jus with sautéed cremini and shiitake offers an earthy alternative. A splash of brandy or port in the au jus adds complexity.

Conclusion
Crafting this Prime Rib Feast with Truffle Au Jus is culinary artistry. The rich, savory prime rib, with its perfect crust and tender interior, finds its ideal companion in the earthy, aromatic truffle au jus.
