King Ranch Chicken Casserole

Preheat oven to 350 degrees. Heat oil in a large skillet over medium heat. Saute the onion, bell peppers, and minced garlic until soft. In a large bowl, add the softened pepper mixture, condensed soups, diced tomatoes, chicken broth, sour cream, cumin, paprika, chili powder, and oregano. Stir until sauce is well-combined. In a separate mixing bowl, add the shredded rotisserie chicken, diced green chili's, onion and garlic powders and a little salt and pepper. Stir to combine well. Spread a few tablespoons of the sauce in the bottom of a 9x13-inch baking dish. Spread 1/2 the chicken over the sauce. Spread about half the sauce over the chicken and top with 1/3 the cheeses. Spread a layer of chips over the cheese. Spread remaining 1/2 the chicken over the chips, and top with almost all of the remaining sauce, reserving 1/2 cup sauce. Top with 1/3 the cheese, chips, the reserved 1/2 cup sauce, and remaining 1/3 cheese. Bake casserole in the preheated oven until bubbling, about 40 minutes. Serve topped with sour cream and a side of sweet corn bread casserole.
