You could also make this yummy baked beans casserole without the ground beef or bacon and serve it as a tasty side dish or a vegan main. To make the Baked Bean Casserole completely vegan, use your favorite vegan ground beef and bacon substitutes or omit the bacon and ground beef altogether. Also, be sure to sub extra soy sauce (or even a small amount of miso paste) to replace the Worcestershire. Then this Calico Beans (Cowboy Beans) recipe can be a scrumptious vegan main, too.
