Ingredients for a Perfect 15 Bean Soup Slow Cooker Recipe
The Essentials for Your Slow Cooker 15 Bean Soup
To make this cooker 15 bean soup recipe, you’ll need a 15-bean mix, which is usually a variety of dried beans like kidney beans, pinto beans, navy beans, and more. You’ll also need diced ham or a ham bone for that delicious smoky flavor, along with garlic, onions, and celery for flavor. Finally, you’ll need chicken broth (or vegetable broth for a vegetarian version) and seasonings like chili powder and a bay leaf to add depth to the soup.
Optional Ingredients for Extra Flavor
If you love a bit of tang and extra richness, consider adding a can of diced tomatoes. The tomatoes add a subtle acidity that balances the richness of the broth. If you enjoy a little kick, a sprinkle of chili powder or smoke from a smoked ham hock will give the soup an extra layer of flavor.
Preparing the Dry Beans for Cooking
Soaking the Beans: Do You Really Need To?
One of the most common questions when making 15 bean soup is whether you need to soak the beans beforehand. The answer is yes, soaking the beans overnight helps to reduce cooking time and ensures that they cook evenly. If you’re short on time, you can opt for a quick soak by boiling the beans for a few minutes and letting them sit for about an hour before draining and adding them to the crockpot.

Rinsing and Preparing the Beans
Be sure to rinse the dry beans thoroughly to remove any dust or dirt. Many bean soup mixes come with a seasoning packet that adds extra flavor, but you can choose to use it or make your own seasoning blend to suit your taste.
Cooking the 15 Bean Soup in the Slow Cooker
How Long Should You Cook the Soup?
Once everything is added to the crockpot, set the slow cooker to high and let it cook for about 4-5 hours. Alternatively, you can set it to low and cook for 7-8 hours, depending on your schedule. The key is to ensure that the beans are tender and the broth has absorbed all the flavors. If you like a thicker soup, you can mash some of the beans toward the end of cooking, which will naturally thicken the soup.
Adding Ham for Extra Flavor
If you’re using a ham bone or diced ham, add it to the slow cooker after the first 3 hours. The longer the ham simmers in the broth, the more smoke and flavor it imparts to the soup. You can even add some leftover ham if you have it on hand for an easy way to use up any extras.
Final Steps and Serving Your Hearty Soup
Don’t Forget to Remove the Bay Leaf
Once the soup is ready, be sure to remove the bay leaf before serving. Stir the soup to ensure that all the flavors are well-combined. If needed, adjust the seasoning with salt, pepper, or even a dash of chili powder to suit your taste.
Serve and Enjoy!
