Creating this incredible White Chicken Chili is straightforward if you follow these clear steps:

1. Cook the Chicken: In a large pot or Dutch oven, heat the olive oil over medium heat. Add the chicken breasts and cook until browned on both sides (about 5-7 minutes). Remove the chicken and set aside.

2. Sauté Aromatics: In the same pot, add diced onions and sauté for 3-4 minutes until translucent. Add minced garlic and cook until fragrant (about 1 minute).

3. Add Spices: Stir in the cumin, paprika, oregano, salt, and pepper. Cook for another 1-2 minutes to allow the spices to toast slightly.

4. Combine Ingredients: Return the chicken to the pot. Add the white beans, green chilies, chicken broth, and corn, stirring to combine.

5. Cook the Chili: Bring the mixture to a simmer. Cover the pot and let it cook for 20 minutes, allowing the flavors to meld together.

6. Shred the Chicken: After cooking, remove the chicken breasts and shred them using two forks. Return the shredded chicken to the pot.

7. Add Creaminess: Stir in the sour cream until fully incorporated, and adjust seasoning as needed with salt and pepper.

8. Serve and Garnish: Ladle the chili into bowls. Top with cilantro and any additional toppings like cheese or avocado, if desired.
