Add olive oil and butter to a pan along with the onions, garlic and ¼ teaspoon of cumin. Cook until softened, about 5 minutes.
Add ¼ cup of flour and stir constantly for about 4 minutes.
Slowly whisk in 1 cup of chicken broth and bring to a low simmer. Once it thickens, turn off and set aside.
In a small bowl mix together the oregano, onion powder, chili powder, adobo, Lawry’s, McCormick, cayenne pepper and the rest of the cumin.
Clean chicken breast and add to the slow cooker. Sprinkle the seasonings on both sides of the chicken.
Add the onion mixture, beans, green chiles, corn, and remaining chicken broth to the slow cooker. Stir ingredients together and cover the slow cooker.
Cook on low heat for 5 hours.
When the chili is ready, turn off the slow cooker. Remove the chicken breast and transfer to a clean cutting board. Use a fork to shred the chicken.
Use a cup to scoop out about 1 cup of the chili into a blender and blend into a puree.
Add the shredded chicken and puree back into the slow cooker. Mix in a cup of shredded cheese and more seasoning if needed.
When you are ready to serve, ladle the chili in a bowl, top with cheese, chopped scallions, and any other toppings you enjoy!
