- Season the prime rib generously with kosher salt and rest in the refrigerator for at least 24 hours. Let it sit at room temperature for 5-6 hours before cooking.
- Preheat your oven to 250°F (120°C).
- In a large pot, heat olive oil and brown the meaty bones. Add garlic, carrots, celery, and onion, cooking until softened.
- Stir in tomato paste, deglaze with red wine, and add stock, thyme, and bay leaf.
- Insert a meat thermometer into the thickest part of the prime rib and roast in the oven until it reaches 115°F for rare or 120°F for medium-rare, about 3 hours.
- Once done, remove the roast and tent with foil. Let it rest for 20-30 minutes.
- Switch the oven to broil, broil the roast for 1-2 minutes per side to achieve a crispy crust.
