Cross-Rib or Standing Rib
In my books the best oven roasts have bones in them. For an inexpensive delicious meal for two or three I often buy a small Cross-Rib roast, and cover it copiously with garlic salt and pepper. Delicious and inexpensive. I use a high heat method, cook it at 500 until the center temperature reaches *130, then let it stand for about 15 minutes. If I am having more people over, I'll purchase a three or more rib Standing Rib or Prime Rib, and use a modified high heat method - 500 for 45 minutes. Lower the heat to 325 for about half an hour, then turn it up to 450 until the internal temp reaches *130, usually about another 15 - 30 minutes. I use an instant read thermometer to get the temp right every time. That or a probe take the guess work out. I have found that a roast can sit quite happily on the counter wrapped in tin foil for a fair amount of time if other things need cooking, like Yorkshire Puddings.
