Ingredients and Variations

Beans – We like Hurst’s Hambeens, but Goya has a variety and so will many chain supermarkets. Assorted beans and lentils like pintos, navy beans, baby limas, garbanzos, split peas, red & white kidney, black beans, yellow split peas, and more are packaged with a seasoning packet that infuses the beans with savory flavor. Always rinse beans before using them to remove any dirt or debris.

Pork – Diced ham and bacon add meaty flavor to 15 bean Cajun soup, but this is a great recipe for repurposing leftover ham hocks (shank) or ham bones (leg). Other zesty pork options are smoked sausage, Polska kielbasa, or for an authentic Cajun meal, use Andouille sausage.

Seasoning – If you can’t find the 15 Bean blend with the Cajun seasoning packet, make your own and have plenty of extra for future recipes!

Variations – Add some spinach, kale, celery, carrots, or a frozen bag of mixed veggies to add more flavor, color, and texture to Cajun 15 bean soup. Add them in Step 3. For a vegetarian version, simply leave any meat-based ingredients out, but follow the rest of the recipe.
