In a large saucepan, heat 1 tablespoon of oil over medium heat. Add 1 pound of sliced andouille sausage and cook for 5-7 minutes, allowing it to brown nicely. Stir occasionally until the sausage is fully cooked and releases its smoky aroma, then remove it from the pan and set it aside to keep warm.

In the same saucepan, season 1 pound of boneless and skinless chicken with 1 teaspoon of Cajun seasoning. Add the chicken to the pan and cook for about 5-7 minutes, turning once to achieve a light golden brown color on both sides. Once done, remove the chicken and set it aside to rest before shredding.

Melt 1 tablespoon of butter in the same saucepan over medium heat. Add 1 cup of diced onion, 1 cup of diced celery, 1 cup of diced bell pepper, and 1 finely diced jalapeno pepper. Sauté for 7-10 minutes until the vegetables are tender and fragrant, stirring occasionally to ensure even cooking.

Stir in 4 cloves of chopped garlic, 1 teaspoon of ground cumin, and an additional 1 tablespoon of Cajun seasoning into the vegetable mixture. Cook for about 1 minute, allowing the spices to become fragrant and infuse the vegetables, which will deepen the flavor of your Cajun White Chicken Chili.

Pour in 4 cups of chicken broth along with 2 cans of white beans (rinsed and drained) and ½ cup of salsa verde. Stir the mixture well and bring it to a rapid boil. Once boiling, reduce the heat and let it simmer for 15 minutes, stirring occasionally to combine the flavors beautifully.

After simmering, remove the cooked chicken from the pot, and shred or slice it into bite-sized pieces. Return the shredded chicken to the pot, mixing it back into the chili to absorb all the wonderful Cajun flavors as it simmers.

Add ½ cup of sour cream and ¼ cup of grated Parmigiano Reggiano to the pot, stirring gently until both are melted and incorporated into the chili. This will create a rich and creamy texture that enhances the comforting quality of your Cajun White Chicken Chili.

To finish, stir in 1 tablespoon of lime juice, and sprinkle in the optional cilantro and thinly sliced green onions. Taste and adjust the seasoning with salt and pepper as needed before serving. This will elevate your Cajun White Chicken Chili, giving it a fresh and vibrant flavor profile.
