Why Make Cajun 15 Bean Soup:
- No soaking: This recipe doesn’t require you to soak the beans overnight before cooking them. Just dump the dried beans in the pressure cooker pot and cook.
- Quickest no-soak method: Using an instant pot to cook beans without soaking them saves time. It would take you hours to make this dish in a Crock Pot Slow Cooker.
- Cajun flavors in soup form: This cajun 15-bean soup contains juicy andouille sausage, diced vegetables, and homemade cajun seasoning. allows you to enjoy your favorite cajun flavors in soup form.
- Smoked sausage: This gives the soup a smoky flavor so don’t skip it. I used andouille sausage and cut it into 1-inch wide pieces. You can use the pork, chicken, or turkey varieties.
- Yellow onions: Diced, I used about half a yellow onion
- Pepper: Diced, I used red bell pepper
- Celery: Diced
- Cloves garlic: Minced
- 15 bean soup mix: This is available in most grocery stores. Some stores also have 13-bean soup or 7-bean soup mixes, which work for this recipe.
- Better than Chicken bouillon: this chicken base has much more flavor than broth. So, I’m using it instead of chicken broth (or chicken stock).
- Bay leaves
- Black pepper
- Homemade cajun seasoning: this is my homemade spice blend. It includes things like garlic powder, onion powder, dried parsley, and cayenne pepper.

How To Make Instant Pot 15 Bean Soup
- Add the dry beans to a mesh strainer. Rinse under cold water for 1 minute. Allow to drain.
- Add avocado oil to the bottom of the instant pot on high to sear/saute. Add sausages, peppers, celery, onions and garlic. Saute for 5 minutes (the onions will be translucent, and the sausages will be browned). Turn off the sear-saute function on the Instant Pot.
- Add the rinsed beans, water, bouillon, and bay leaves. Stir to combine. Turn on high pressure for 40 minutes. At the end of the cooking time, allow the soup to stay with the lid on for 20 minutes before manually removing the remaining pressure (I find that this is the best way to ensure that all of the beans are tender).
- Stir, add seasonings, salt and pepper to taste (optional).
Recipe Tips & FAQs
- Alternatives for smoked sausage: You can also use smoked ham hocks, smoked turkey, ham steak, cubed pancetta, or bacon.
- I use Better than chicken bouillon: It has more flavor than chicken broth or chicken stock, so I use this with water instead of regular broth.
- Works with any pressure cooker: You can use an Instant Pot or the Ninja Foodi to prepare this recipe.
- Allow natural pressure release: Allowing the pressure cooker to release the pressure naturally for 20 minutes ensures that all the beans are tender. If you’re in a rush, you can manually remove the pressure, but some of the beans won’t be as tender.
