Creating White Chicken Chili is a simple process if you follow these steps:

1. Sauté the Aromatics: In a large pot, heat the olive oil over medium heat. Add the diced onion and cook until softened, about 5 minutes. Stir in the minced garlic and cook for another minute until fragrant.
2. Add Ingredients: Add the shredded chicken, white beans, diced green chilies, chicken broth, cumin, chili powder, and oregano. Stir well to combine.
3. Simmer: Bring the mixture to a boil, then reduce the heat to low. Allow it to simmer for about 20 minutes, letting the flavors meld together.
4. Incorporate Creaminess: Stir in sour cream and half of the shredded cheese. Mix until well combined and heated through.
5. Season: Taste and adjust seasoning with salt and pepper as needed.
6. Serve: Ladle the chili into bowls and sprinkle the remaining cheese on top. Garnish with fresh cilantro if desired.
