Preheat oven to 250. Place chuck roast in a roasting pan. Season the way you like. I normally use a steak seasoning, use onion, garlic, salt, pepper and I use Dale's seasoning. I baked on 250 for 5hrs. The last 2-3hrs put temp on 150. Be careful! I would check your chuck every 30 minutes. To make sure it's not over cooking. If you have to lower the temp go ahead. It can go from tender fall apart to hard pretty quick. I cut a sample of the meat to make sure it was tender enough.
