This is the easiest and best recipe you can do for Prime Rib.
Heat oven to 500
Season your roast Place on baking pan rib side up
you are going to cook 5 minutes per pound for medium rare. for 17 pounds you will cook for 85 minutes. After the timer goes off turn off the oven and leave for 1 hour. Do not open the oven for this period of time. Serve immediately with you other special dishes. Enjoy!
I guess you already know about the large roast pan part. Just roast it uncovered at 20 min per pound at 325. You can rub it with any seasoning you like. I like to make slits in it here and there and insert fresh garlic cloves.
Do you have an electric thermometer? If not get one. You be roasting better than ever before.
I’ll gladly come over to make sure it tastes right too =)
