Dice the onion into 1/4-inch pieces, seed and dice the jalapeños into 1/4-inch pieces, and mince the garlic cloves. Melt the butter in a large skillet over medium heat, then add the diced onion and jalapeños. Sauté for 5 minutes until softened and fragrant. Add the minced garlic and cook for another 30 seconds until aromatic. This flavor foundation will build complexity into your chili.
In a small bowl, whisk together the ranch mix, chili flakes, cumin, chili powder, and onion powder. Set aside. I like to combine my spices before the slow cooker so they distribute evenly and don't clump together in the liquid.
Transfer the sautéed aromatics from Step 1 into your slow cooker. Add the drained and rinsed black beans, sweet corn, Rotel (with its juices), and chicken breast. Pour in the chicken broth and stir in the dry spice blend from Step 2. Nestle the softened cream cheese on top of the mixture but do not stir it in yet—it will incorporate as the chili cooks and creates a creamier, more luxurious texture.
Cover and cook on low for 6 to 8 hours. The chicken should be completely tender and shred easily with a fork. During the last 30 minutes of cooking, shred the chicken directly in the slow cooker using two forks, breaking it into bite-sized pieces. Stir the chili thoroughly to incorporate the cream cheese fully and create a smooth, creamy base.
Stir in the fresh lime juice and freshly shredded cheddar cheese until melted and fully incorporated. Taste and adjust seasoning if needed—the lime adds brightness that balances the richness of the cream cheese and jalapeño heat. Fold in the crumbled bacon gently to maintain its texture.
Ladle the chili into bowls and top with a dollop of sour cream, a handful of tortilla chips for crunch, and a sprinkle of fresh cilantro for color and brightness. I find that serving toppings on the side lets guests customize their bowl, and the sour cream helps cool down the jalapeño heat nicely.
