Creating this delicious white chicken chili is simple and straightforward. Follow these steps for a perfect outcome:

1. Prepare the Chicken: In a large pot, heat olive oil over medium heat. Add the chicken breasts and cook until browned on both sides, about 5-7 minutes. Remove chicken and set aside.
2. Sauté Aromatics: In the same pot, add chopped onion and garlic. Sauté until the onion becomes translucent, about 3-4 minutes.
3. Add Beans and Spices: Add the drained white beans, diced green chilies, cumin, chili powder, oregano, salt, and pepper to the pot. Stir to combine the ingredients well.
4. Pour in Broth: Return the cooked chicken to the pot and pour in the chicken broth. Bring the mixture to a gentle simmer.
5. Cook the Chicken: Cover the pot and let it simmer for 20 minutes. After shaping the spices into the broth, ensure the chicken is fully cooked.
6. Shred the Chicken: Use two forks to shred the chicken directly in the pot. Stir well to incorporate the chicken with the chili.
7. Finish with Lime: Stir in the lime juice for a refreshing tang. If desired, add sour cream to achieve a creamier texture.
8. Garnish and Serve: Ladle the chili into bowls and garnish with fresh cilantro and shredded cheese, if preferred.

Following these steps will result in a mouthwatering bowl of white chicken chili that is sure to impress!
