How To Make Crock Pot 15 Bean Cajun Soup
- Quick soak the beans: Bring a large saucepan of water to a boil. Add the beans, turn off the heat, cover, and let sit for 1 hour. Drain and set aside.
- Combine base ingredients: Add the soaked beans, chopped onion, green bell pepper, celery, garlic, chicken broth (or water), and bay leaves to the Crock Pot.
- Start slow cooking: Cook on high for 4 hours or on low for 7-8 hours, until the beans begin to soften.
- Add meats and seasonings: About 1 hour before the end of cooking on high (or 2 hours on low), add the Cajun seasoning, diced tomatoes, tomato paste, chicken base, sausage, ham, and bacon. Stir, cover, and continue cooking.
- Finish and serve: Remove bay leaves. Stir in parsley, cayenne pepper, and salt and black pepper to taste. Serve warm.

Recipe Tips
- Do I need to soak the beans overnight?
No, a quick soak method works just as well: boil, cover, let sit for an hour, then drain. - Can I make this soup ahead of time?
Yes, it stores well in the fridge for 1-2 days and tastes even better as leftovers. - What if I don’t have Andouille sausage?
You can substitute with smoked sausage or kielbasa for a similar flavor. - How spicy is this soup?
The heat level depends on your Cajun seasoning and cayenne. Adjust both to your taste. - Can I skip the bacon or ham?
Yes, but the flavor will be slightly different. Add extra sausage or seasonings if desired.

FAQs
Can I use canned beans instead of dried?
No, canned beans will become too mushy during the long cook time. Stick with dried for best texture.
Why is my soup too thick?
Beans naturally thicken the soup. Add more broth or water to thin it out as needed.
Can I make this vegetarian?
Yes. Skip the sausage, ham, and bacon. Use vegetable broth and add more veggies or beans.
What kind of Cajun seasoning should I use?
Use your favorite store-bought blend or homemade mix. Adjust salt and spice to taste.
Is this recipe gluten-free?
It can be, if you check that all ingredients (especially sausage and broth) are gluten-free.
