Heat 1 tablespoon olive oil in a skillet over medium heat. Add the ground chicken, cumin, smoked paprika, fennel seeds, oregano, chili powder, crushed red pepper flakes (if using), and a pinch of salt and pepper. Brown the chicken, breaking it into small pieces as it cooks.
Transfer the browned chicken to the crockpot. Add the sautéed onion, celery, and carrots (if using), garlic, drained white beans, corn, and chicken broth. Stir to combine and season with additional salt and pepper to taste.
Cover and cook on low for 6–7 hours or high for 3–4 hours, until the chicken is fully cooked and the flavors are well blended.
Serve hot with your choice of toppings such as shredded cheese, avocado, cilantro, lime wedges, or tortilla chips.
