Sear the Chicken In a large pot, heat avocado oil over medium heat. Season chicken thighs with salt and pepper, then sear for 3–4 minutes per side until lightly golden. Remove and set aside.
Sauté the Aromatics In the same pot, add diced onion, green bell pepper, jalapeño, and garlic. Cook for 3–4 minutes until softened and fragrant.
Add the Spices Stir in chili powder, cumin, garlic powder, onion powder, salt, and black pepper. Cook for 30 seconds to bloom the spices and deepen the flavor.
Build the Base Pour in the chicken stock and return seared chicken thighs to the pot. Bring to a boil, then reduce to a simmer. Cook uncovered for 20–25 minutes, until chicken is tender and fully cooked.
Shred and Combine Remove the chicken from the pot and shred it using two forks. Return it to the pot along with diced green chiles, white beans, corn, cream cheese, and heavy cream. Stir well until creamy and combined. Simmer for another 5–10 minutes to thicken.
Serve Ladle into bowls and top with sliced avocado, chopped cilantro, sour cream, and a squeeze of lime.
