<strong>Stovetop Directions:</strong> In a 4- or 5-quart pot, heat the oil over medium heat. Add the chicken, onion, and garlic powder (or fresh garlic, if using). Cook, stirring occasionally, for 1-2 minutes, until the onion starts to soften (it's ok if the chicken isn't cooked all the way; it will cook more in the next step). Add the beans, broth, chiles, salt, cumin, oregano, pepper and cayenne. Bring the mixture to a simmer and cook, uncovered, for 15 to 30 minutes. Remove from the heat; stir in the sour cream and cream. Garnish with fresh cilantro, if desired. Serve immediately with other toppings of choice, if desired. <strong>Slow Cooker Directions:</strong> In a 5- or 6-quart slow cooker, place 1 pound boneless, skinless chicken breasts whole (without cutting into pieces). Add the chopped onion, garlic powder, beans, green chiles and all of the spices. Do not add the sour cream or whipping cream yet! Reduce the chicken broth to 12 ounces (about 1 1/2 cups) and pour in over the other ingredients. Stir the mixture around a bit to incorporate the dry spices. Cook on low for 5-7 hours. Remove the chicken to a cutting board and shred in bite-size pieces (or use a couple forks and shred right in the slow cooker). Add the shredded chicken back into the slow cooker. In a small bowl or liquid measuring cup, whisk together the sour cream and whipping cream until smooth. Whisk the cream mixture into the crockpot with the other ingredients. Let the chili cook warm through on low temperature. Serve.
