Preheat the oven to 350 degrees F.
Add the bacon to a large skillet and fry over medium heat until browned, 8 to 10 minutes. Remove the bacon to a paper towel-lined plate and remove all but 4 tablespoons bacon fat from the skillet.
Add the beans, ketchup, molasses, brown sugar, dry mustard and onions to an 8-by-8-inch casserole dish. Add in the bacon fat from the skillet. Lay the reserved bacon strips on top of the bean mixture. Bake until heated through, 30 to 45 minutes.
