Prime Rib

Ingredients

• (1) prime rib roast
  
• (3 medium) onions (thickly sliced)
• (1 tsp) Kosher or coarse sea salt per pound of roast 
• (1⁄2 tsp) freshly ground black pepper per pound
• (1 tsp) minced garlic per pound
• (1 tsp) fresh rosemary per pound
• (1 tsp) fresh thyme per pound
• (1⁄2 tsp) olive oil per pound
• (1⁄4-1⁄2 cup) Worcestershire sauce
• (1⁄4-1⁄2 cup) Bouquet sauce
• (1⁄4-1⁄2 cup) melted butter

Directions

1. Before marinating, give your prime rib roast a quick rinse with cold water, and pat it dry with paper towels.
   
2. Place a flat roasting rack inside a roasting pan. Spread the onions on top of the rack. If you donʼt have a roasting rack, resting the roast directly on the onions works also. Place the roast in the pan.
3. Mix the salt, pepper, garlic, herbs, olive oil, sauces and butter in a bowl until well-combined. Use your hands to rub the roast all over with the marinade mixture, coating the surface evenly.
4. Use plastic wrap to cover the roast, and let it marinate overnight (at least 8 hours) in the refrigerator.
5. Take the roast out of the refrigerator at least 2 hours before cooking time to allow the roast to come up to room temperature. 
6. Preheat the oven to 450 degrees F. Once heated, place the rack into the oven. Put the roast at the bottom of the oven for the first hour. Placing the oven rack too high up will cause your roast to brown too quickly and burn!
7. After 30 minutes in the oven, add a 1⁄2 cup of water to the bottom of the roasting pan. The key is to allow the onions to brown and caramelize while roasting, but not to burn and smoke in the fat.
   
8. Once the prime rib roast is browned on the outside (1 hour total should do it, but times may vary depending on your oven), lower the heat to 350 degrees F. Rotate the pan to promote even cooking. Continue roasting the prime rib for another 60 to 120 minutes, until the internal temperature reaches 115 F. 
9. Baste the roast every 30 minutes, and add hot water 1⁄2 cup at a time to ensure the roasting pan does not dry up. If the top of the roast starts to char, put a small piece of foil to lightly cover the
   top, leaving the sides exposed. Again, turn the roast 180 degrees if needed for
   even roasting.
10. Let rest on the counter covered by aluminum foil for 30 minutes. Roast will continue to cook while it rests. 
11. Serve with mustard sauce or Au Jus sauce.
