HOW TO COOK BONE IN PRIME RIB RECIPES

Steps:

• Mix up 1 tablespoon + 1 teaspoon each of onion salt, seasoned salt, and garlic powder, for a total of 1/4 cup of seasoning mix.
• Pat the seasoning mix on both ends of the roast as well as the fat side. (The salt may not stick as well on the fat side, but don’t worry about it.)
• Set the seasoned roast on a roasting rack, bone-side down and fat-side up. Place the rack in a large roasting pan, and insert your meat thermometer into the middle of the roast.
• Place the roast into a 500° preheated oven, uncovered, and cook for 5-6 minutes per pound.
• Then shut the oven off completely, and DO NOT OPEN THE OVEN DOOR FOR TWO HOURS. 
• After two hours, check the temperature of the meat. If your thermometer reads 135-140°F, it’s done! (If it isn't quite to temp yet, just put it back in the oven at 375°F until it's done.)
• Creamy Horseradish Sauce

Steps:

• Preheat oven to 500°F.
• Cut rib loin in half (roast halves separately for more controlled/even cooking.)
• Sear both halves in olive oil over very high heat until nice dark golden color. Place tricolor peppercorns into a bag, crush pepper corns with a rolling pin. Strip the leaves from the rosemary and thyme springs. Mix salt, crushed peppercorns, rosemary leaves, thyme leaves and garlic. 
• Pour olive oil over the rib loin and pour on the rub mix. Pat slightly to get it to stick to the meat. Roast for 20-30 minutes at 500 degrees, then reduce heat to 300°F and roast for another 20 to 30 minutes or until a meat thermometer registers 125 for rare/medium rare (roast will continue to cook slightly after removing from the oven.) NOTE: If you'd like the meat more cooked, leave it in the oven longer. Just keep an eye on the meat thermometer and don't let it cook past medium rare! **USING A MEAT THERMOMETER IS VERY IMPORTANT TO ENSURE YOU COOK THE MEAT TO YOUR LIKING***
• Remove from oven and let rest at least 20 minutes before slicing.
