What You’ll Need for This Slow Cooker Bean Soup
A quality 15 bean mix is the foundation of this recipe because it provides wonderful variety in texture and flavor. The overnight soak is essential, it makes a huge difference in how evenly the beans cook. Here’s everything you’ll need:
- 1 (15 ounce) package 15 bean mix, dry (discard the seasoning packet – this recipe uses its own spices)
- 2 carrots, chopped
- 2 celery stalks, chopped
- 1 small onion, chopped
- 3 cloves garlic, minced
- 1 cup diced ham, pre-cooked (ham steak or pre-diced ham works perfectly)
- 1 (14.5 ounce) can diced tomatoes with juice
- 1 teaspoon dried Italian seasoning
- 1 teaspoon smoked paprika (adds incredible smoky depth)
- 1 teaspoon salt (adjust after cooking based on your broth saltiness)
- 1/2 teaspoon chili powder
- 1/2 teaspoon ground cumin
- 1/2 teaspoon black pepper
- 1 bay leaf
- 7 cups chicken broth (use 6 cups for thicker soup, 8 cups for brothier texture)
My recommendation: Taste the soup before serving and adjust the seasonings. Some bean mixes and broths are saltier than others, so it’s best to add salt gradually. I learned this the hard way when I over-salted my first batch!
How to Make 15 Bean Soup in Your Crockpot
Starting this recipe the night before by soaking your beans is essential. This simple step ensures perfectly tender beans every time.
Step 1: Rinse the 15 bean mix thoroughly under cold water, checking carefully for any small stones or debris. Place the beans in a large bowl and cover with cold water (about 3-4 inches above the beans, as they’ll expand). Let them soak overnight, which takes 8-10 hours at room temperature or in the refrigerator if your kitchen is very warm.
Step 2: The next morning, drain and rinse the soaked beans thoroughly. They should look plumper and about double their original size.
Step 3: In a large microwave-safe bowl, combine your chopped carrots, celery, onion, and minced garlic. Cover with a damp paper towel and microwave on high for 3-4 minutes until the vegetables are slightly softened and fragrant. This is an optional time-saver, the vegetables will soften during the long cook time if you prefer to skip this step.
Step 4: Transfer your soaked beans to a 6-8 quart slow cooker. Add the vegetables (microwaved or raw), diced ham, canned tomatoes with all their juice, Italian seasoning, smoked paprika, salt, chili powder, cumin, black pepper, and bay leaf.
Step 5: Pour in 7 cups of chicken broth for a perfectly balanced consistency (use 6 cups if you prefer thicker soup, 8 cups for brothier texture). Stir everything together until well combined.
Step 6: Cover the slow cooker with the lid and cook on low for 8 hours or on high for 4 hours. The beans should be completely tender when tested with a fork, they should mash easily but not be mushy. Since different bean varieties cook at slightly different rates, taste-test a few different types to ensure they’re all done.
Step 7: Once cooking is complete, carefully remove and discard the bay leaf. Taste the soup and adjust salt and spices to your preference. If you want a thicker soup, mash some of the beans against the side of the slow cooker or make a quick cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water, stirred in during the last 30 minutes).
Step 8: Ladle the hot 15 bean soup slow cooker into bowls and serve immediately with your favorite sides.

Storing Your Homemade Bean Soup
This 15 bean soup slow cooker recipe stores beautifully, making it perfect for meal prep. Let the soup cool completely before transferring it to airtight containers. You can refrigerate it for 3-4 days, and the flavors actually deepen and improve after a day in the fridge. Note that the soup will thicken as it sits, this is normal.
For longer storage, place cooled soup in freezer-safe bags, flatten them to remove excess air, and freeze for 2-3 months. Freeze in individual portions so you can thaw exactly what you need for quick lunches or dinners.
When reheating, you can use the microwave in a microwave-safe bowl or warm it gently in a saucepan over low heat. Add a splash of chicken broth if the soup has thickened too much during storage. Making a double batch of this bean soup recipe is smart because it’s so convenient to have ready-made meals waiting in the freezer.
Common Questions About 15 Bean Soup
Can I make this 15 bean soup slow cooker recipe without soaking the beans overnight?
While you technically can skip soaking, it’s not recommended. Unsoaked beans take much longer to cook (10-12 hours on low) and may cook unevenly, with some beans staying hard while others get mushy. The overnight soak ensures consistent results.
What can I substitute for ham in this bean soup?
You can easily make this vegetarian by omitting the ham and using vegetable broth instead of chicken broth. For a different flavor, try 12 oz hot Italian sausage (browned first), 6-8 strips of cooked crumbled bacon, or smoked turkey for equally delicious results.
Why are my beans still hard after 8 hours of cooking?
Old beans (over a year old) won’t soften properly no matter how long you cook them. Also, adding acidic ingredients like tomatoes at the beginning can slow bean softening. If this happens, remove the tomatoes next time and add them during the last 2 hours of cooking. Hard water can also affect bean cooking, try using filtered water for soaking.
Why is my slow cooker soup too thin or too thick?
Adjust the consistency by adding more broth if it’s too thick or making a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) if it’s too thin. You can also mash some beans against the side of the pot to naturally thicken the 15 bean soup.
