For a bone-in ribeye roast cooked to rare doneness, preheat your oven to 450°F. Place the roast on a rack in a roasting pan with the fat side up. Cook for about 15 minutes, then reduce the heat to 350°F and continue cooking for approximately 1 hour and 15 minutes, or until the internal temperature reaches 125°F. Remember to let the roast rest for 15-20 minutes before slicing to allow the juices to redistribute.
If you prefer your bone-in ribeye roast cooked to medium doneness, follow the same initial steps as for rare doneness. However, cook the roast at 450°F for 15 minutes, then lower the heat to 350°F and continue cooking for about 1 hour and 30 minutes, or until the internal temperature reaches 135°F. Let the roast rest for 15-20 minutes before carving for the best results.
For Well-Done Doneness:
To achieve a well-done bone-in ribeye roast, start by preheating your oven to 450°F. Place the roast in a roasting pan with the fat side up and cook at 450°F for 15 minutes. Reduce the heat to 350°F and continue cooking for approximately 2 hours, or until the internal temperature reaches 150°F. Allow the roast to rest for 15-20 minutes before slicing to ensure juiciness.
