Foolproof Rib Roast

•  1 (5 pound) standing beef rib roast
• 2 teaspoons salt
• 1 teaspoon ground black pepper
• 1 teaspoon garlic powder

1. Allow roast to stand at room temperature for at least 1 hour.
2. Preheat the oven to 375 degrees F (190 degrees C). Combine the salt, pepper and garlic powder in a small cup. Place the roast on a rack in a roasting pan so that the fatty side is up and the rib side is on the bottom. Rub the seasoning onto the roast.
3. Roast for 1 hour in the preheated oven. Turn the oven off and leave the roast inside. Do not open the door. Leave it in there for 3 hours. 30 to 40 minutes before serving, turn the oven back on at 375 degrees F (190 degrees C) to reheat the roast. The internal temperature should be at least 145 degrees F (62 degrees C). Remove from the oven and let rest for 10 minutes before carving into servings. 

It turned out really yummy! I did rub it in olive oil before I rubbed in the spices, but I think I made it too greasy. I used an arm roast instead of a rib roast, and I should have only cooked it a half hour before I turned it off the first time—it was plenty done by dinner. But the flavor was really yummy and it was super tender!
