15 Bean Soup is a hearty and delicious soup that is perfect for the cool weather of fall. Traditionally made with a variety of beans, 15 Bean Soup gets its name from the 15 different types of beans that are used in the recipe.

While the exact blend of beans varies depending on the region, some common varieties include black-eyed peas, navy beans, and kidney beans. 15 Bean Soup is typically slow-cooked in a crock pot or stovetop, allowing the flavors of the beans to meld together and create a rich and hearty soup.

I like using low sodium bouillon paste for my recipes, but you can also use bouillon cubes or powder. All are less expensive than cartons of stock or broth.

Ingredients for 15 bean soup in the slow cooker

Do you need to soak the dry beans?

The best part about cooking dry beans in a slow cooker is that you don’t HAVE to soak them ahead. Then, you’ll want to use the full cooking time to be sure your beans soften.

If you do want to soak the beans overnight, plan to drain them in the morning and then only add 1 cup of water for the broth. The soaked beans will release moisture while they cook, so you don’t need to add as much to the recipe.

Is this recipe for 15 bean soup vegan?

It is! 15 bean soup is naturally vegetarian and vegan, as long as you use vegetable broth or stock as the base. The main protein in this meal is the beans.

Some bags of 15 bean soup mix may include a seasoning packet, so be aware that there may be ham or other meat products in the seasoning.

What to serve with crock pot 15 bean soup

Cornbread is a traditional side that’s perfect for this soup! If you need to avoid eggs and dairy, consider making vegan cornbread. That’s my personal favorite side for this yummy soup, but Italian crusty bread or dinner rolls would also be delicious.

Other side dishes that would go well are cheddar biscuits, rice (you can even add that to the soup bowl), or a fresh salad.

Making soups, stews and chili in the crock pot is also a good way to deal with those busy evenings where everyone is eating dinner at a different time. With busy teens and busy parents, this works great for us! If you enjoy our crock pot 15 bean soup, you may also like:

We are not vegetarians, so I add diced turkey Kielbasa to our soup. I have never tried it in the crockpot but will definitely do so next time.
