. Sauté Aromatics: Heat oil in a large pot or Dutch oven over medium heat. Add the chopped onion and cook until softened, about 5 minutes.
Bloom Spices: Stir in the minced garlic, cumin, oregano, smoked paprika, and red pepper flakes (if using). Cook for 1 minute until fragrant.
Simmer: Pour in the chicken broth, then add the rinsed and drained white beans and green chiles. Bring the mixture to a simmer.
Create Creaminess: To create a thick base, remove about 1/3 of the bean mixture and blend it smooth in a blender, or use an immersion blender directly in the pot to partially blend the contents. Return the blended mixture to the pot and stir well.
Add Chicken: Stir in the cooked, shredded chicken. Continue to simmer for 10-15 minutes, allowing the flavors to meld and the chili to thicken.
Chef's Tip for Deeper Flavor: For a richer broth, lightly brown the pre-cooked shredded chicken with the spices for a minute before adding the broth. A teaspoon of chicken bouillon powder can also add a wonderful umami boost.
Temper the Dairy: Remove the pot completely from the heat. Let it cool for a minute, then carefully stir in the Greek yogurt or blended cottage cheese until fully incorporated and creamy. *Crucially, do not boil the chili after this step to prevent curdling.*
Finish: Season with salt, black pepper, and fresh lime juice to taste. Serve hot, garnished with fresh cilantro.
