Tonight for Christmas dinner we cooked prime rib. It turned out delicious! I probably should have left it in the oven about 10 more minutes. Here is some documentation of how I cooked it in case you’re interested, and for my own later reference.
This was the recipe I used and modified slightly. We bought 4 pounds of prime rib at Whole Foods, which was 2 bone-in ribs/steaks. We were feeding 7 people. This worked out fine, but I would like to have an extra rib next time for the same number of people.
For the seasoning rub (which turned out amazing) I added some Montreal steak seasoning to the four ingredients included in the recipe: coarse sea salt, onion powder, garlic powder, and pepper. I didn’t baste the sides during cooking. For our 4 pound roast, I cooked it 15 min at 425 degrees and then 1 hour, 15 minutes at 325. The meat thermometer read 130 at the end of the cooking time. I covered it with foil and let it rest for 20 minutes after that. As I said it turned out amazing, but since we had several people who like more well done meat it would have been good to leave it in the oven just a touch longer.
