Start by grabbing your large slow cooker, at least 7 quarts in size. Place all the ingredients, except for the chicken and cilantro, into the slow cooker. Make sure to add the chicken broth, corn, cannellini beans, onion, and jalapeño. Give it all a good stir to combine.
Next, gently add the boneless chicken thighs to the slow cooker. Ensure they’re submerged in the mixture. You want them to absorb all those wonderful flavors as they cook. Secure the lid on your slow cooker and set it to cook on low for 6 to 8 hours or high for 3 to 4 hours, depending on your available time.
Once the cooking time is up, it’s time to check your chili! Carefully remove the chicken from the slow cooker and transfer it to a plate. Use two forks to shred the chicken, which should be perfectly tender after cooking.
Now, scoop out about two cups of the soup from the slow cooker and pour it into a blender. Blend until smooth and creamy. This step adds a lovely texture to your chili. Once blended, pour the purée back into the slow cooker, stirring to combine with the remaining ingredients.
Next, add the shredded chicken back into the slow cooker along with the chopped cilantro. Stir everything together, allowing those flavors to meld for a few more minutes.
Finally, taste your chili and adjust the seasoning if necessary. You might want to add more salt or a dash of pepper. Once satisfied with the flavor, let it sit for a few minutes before serving.
Serve your Crock-Pot White Chicken Chili warm, garnished with extra cilantro if desired. It pairs wonderfully with tortilla chips or cornbread!
