In a small bowl, stir together ketchup, brown sugar, molasses, mustard, and vinegar. Pour over bean mixture and stir well until evenly distributed.
1 ½ cups ketchup, 1 cup packed dark brown sugar, ⅓ cup molasses, 2 tablespoons Dijon mustard, 4 tablespoons white vinegar
Place beans in oven and bake for 2 hours, stirring once halfway through baking time. If you prefer, you can cover the beans with foil while they bake (see note 4).

Notes
Beans: A large jar (or three 15.8 ounce cans) of great Northern beans, along with over-sized butter beans, gives a nice textural contrast. If you'd prefer to use all great Northern beans, that's totally fine too. You can also substitute other types of beans, if you have a favorite. Whatever type you use, be sure to rinse and drain them.
Bacon: If you prefer, place the bacon strips on top of the beans instead of chopping it and mixing it in. If you're not a fan of bacon but still want meaty beans, try ground beef, turkey, or sausage. Brown before adding it to the beans. Link sausages can be added as well, or even hot dogs.
Vegetarian: For vegetarian baked beans, simply omit bacon. The beans have plenty of flavor without bacon but add a ½ teaspoon of smoked paprika for a hint of smokiness, if desired.
Cover the pan: If you prefer beans that have more sauce, cover the pan with foil for the first hour of baking to keep the liquid from evaporating. You can cover the pan the entire time if you prefer.
