These Homestyle Baked Beans are packed full of onion and real bacon. Ketchup, molasses, and brown sugar make up the tangy sauce that gives these baked beans a sweet barbecue natural flavor. They are slow-cooked in the oven. Just 6 ingredients and just 6 steps. This is a classic side dish for your summer cookout to go with hot dogs and potato salad or macaroni salad.
