Start by shredding the rotisserie chicken into smaller pieces. You can use your hands, two forks, or even a mixer to save time. Set the chicken aside while you prepare the other ingredients.
Heat olive oil in a large pot over medium heat. Add the chopped onion, garlic, and canned green chilies (including their liquid). Cook for about 3 minutes until the onions turn soft and translucent. Stir occasionally to prevent burning.
Stir in the cumin, dried oregano, and cayenne pepper (if using). Toasting the spices for a minute helps release their flavors, giving your chili a rich, aromatic base.
Pour the chicken broth, water, and drained white beans into the pot. Then, add the shredded rotisserie chicken. Stir everything together and bring the mixture to a gentle boil. Reduce the heat, cover the pot, and let it simmer for 15 minutes. This will allow the flavors to meld beautifully.
Stir in the juice of one lime and the freshly chopped cilantro. Taste the chili and adjust the seasoning as needed. The lime adds a zesty brightness, while the cilantro gives it a burst of freshness.
Ladle the chili into bowls and add your favorite toppings. Whether you go for creamy avocado slices, crispy tortilla chips, or a generous squeeze of lime, each topping enhances the dish’s flavor.
