Cooking a bone-in prime rib roast can yield a delicious and impressive meal. Generally, it's a good idea to season it generously with salt, pepper, and herbs, then roast it in a preheated oven, starting at a high temperature to create a crust, then lowering it for a slower cook. Using a meat thermometer ensures it's done to your liking. What occasion are you planning to cook a prime rib for? Do you have a favorite way to season your roasts, or are you trying something new?
