Smoky Rotisserie Chicken Taco Soup

Heat the butter and olive oil in a large pot over medium heat. Add the diced onion, garlic, and jalapeños, then cook for 4-5 minutes, stirring often, until the onion softens and the mixture smells fragrant.

Stir in the diced rotisserie chicken, taco seasoning, and chicken broth. Mix well, scraping the bottom of the pot to loosen any flavorful bits.

Add the Rotel tomatoes, chili beans, ranch beans, fire-roasted tomatoes, chili powder, Tony Chachere's seasoning, salt, and black pepper. Stir until evenly combined.
