Is this recipe vegetarian bean soup?

This bean soup is vegetarian! A lot of bean soup recipes use ham to flavor the beans and therefore removes them from the vegetarian category but I love to make this recipe using vegetables and vegetable stock for flavoring.

If you wanted to add ham to the recipe it certainly wouldn’t hurt it but it doesn’t need it. The flavors are great and you can add other veggies / seasonings if you liked as well.

This Crockpot bean soup recipe is also technically vegan so if you are looking for slow cooker vegan recipes it’s worth a try as well! I might be a little biased but I can’t think of a reason for you to NOT try this one.

It’s necessary to soak the beans in water overnight. Don’t skip this step or they’ll be crunchy and not fully cooked when you go to eat your soup.

Soaking beans is really not a difficult process and it allows you to use dry beans which are lower in sodium and much less expensive. They’re also really easy to keep on hand because they store really well and for a long time!
