1. Start by bringing the beef rib to room temperature, you can do this by removing it from the fridge 2–3 hours before you plan to start cooking (this is a key tip for even cooking).
2. Then get a paper towel and pat the meat dry.
3. Then proceed to preheat the oven to 460 degrees Fahrenheit. Make sure you adjust the shelf so the beef is in the center of the oven.
4. Go ahead and combine all the garlic, herb, and butter in a mixing bowl.
5. In a heavy-bottomed oven-proof skillet, proceed to combine the onion, garlic, and herbs for the roasting bed – or you can even simply use a roasting pan.
6. On the underside of the beef rib i.e the bone side, make sure you spread a thin coating of butter. This should be slather 1.
7. Proceed to place the beef rib -butter side down – on top of the onions and other vegetables. You can use ⅔ of the butter and spread it on the top and sides (make sure you reserve some for Slather 2).
8. Go on and roast the beef rib bone-in in the preheated oven for 20 minutes.
9. Then remove the second slather and spread the remaining butter on top. You can reduce the oven temperature to 250 F at this stage.
10. Then proceed to roast for another 1½ hours -make you baste the meat every 30 minutes with the pan juices – until the internal temperature reaches 122 F in the center (this is for medium-rare).
11. Rest the meat when it is ready. Place the steak on a platter and let it rest for 20–30 minutes, covered loosely with foil. You will find that the temperature inside will rise to129°F (which is medium-rare).
12. You can serve the beef sliced with sauce, Paris Mash, and Garlic Sautéed Spinach for a high-end steakhouse experience.
