This slow cooker black bean soup is made with dry beans, and practically makes itself. Dress it up with garnishes such as sour cream, pickled jalapeños or the spicier variety, cilantro, lime, green onions, or avocado.Jump to Recipe
In my world, "slow cooker" is code for easy and hands-off. I've cooked this black bean soup in my slow cooker overnight while I slept. And I've made it when I've been out for the day. All the work is done while I do something else. And sometimes that's the only way dinner is getting made. You have days like that too?
When I crave black bean soup, and want it to be easy, I either make this Instant Pot Black Bean Chili or this slow cooker recipe, which is even easier. If I have a little more time, then I head to this Southwestern Black Bean Soup with Tomatillos and Corn. As you can see by now, I really like black bean soups.

🧅 Main Ingredients + Notes
For the all of the ingredients, measurements and directions, go to the Recipe Card at the bottom of this post.
- Yellow onion - white onion if fine too, but red onion is too sweet.
- Dry black beans (uncooked) - I've used standard black beans, heirloom black beans, and black turtle beans in this recipe, all with great success.
- Garlic - I often use garlic paste because it's so easy.
- Spices - chili powder, dried oregano and Pimenton de la vera (or smoked paprika).
- Vegetable broth - I use Better Than Bouillon paste made from roasted vegetables.

👩🍳 Preparation Tips
No need to pre-soak the beans when cooking them in the slow cooker.
There's some variability in cooking time from one slow cooker to the next. I cook this soup on high for 6 - 7 hours very successfully.
The other factor in cooking time is the beans themselves. It's impossible to know the age of the dried beans. Beans on the shelves of your grocery store could be as old as 2 years. And the older they are, the dryer, and longer it can take to cook. Heirloom beans will generally cook faster because they're almost guaranteed to be more recently dried.
I purée my soup in a countertop blender. If you prefer the black bean soup to be chunkier, either use an immersion blender or remove 1 cup of the soup and puree it before stirring it back into the soup.
Don't add the salsa until the beans in the soup are completely cooked. The vinegar in the salsa can prevent beans from softening.
