Servings: Serves 6 to 8. Nutrition is an estimate per serving, based on 6 servings.
No bacon: Omit the bacon and sauté the onion in olive oil instead.
Make ahead: The beans taste even better the next day, as the flavors deepen overnight.
Storage: Refrigerate in an airtight container for up to 4 days, or freeze for up to 3 months. Thaw overnight in the refrigerator. Reheat gently on the stovetop or in the microwave, adding a splash of water if the beans have thickened too much.
Too watery: Bake uncovered a little longer to reduce and thicken.
