A hearty and flavorful casserole that transforms leftover shredded chicken into a satisfying main dish. Simple to assemble and ready in just 45 minutes, this recipe blends classic Mexican-inspired flavors with the comforting appeal of a baked entrée.
Preheat the oven to 350°F. Lightly grease a 13 x 9-inch baking dish with cooking spray to prevent sticking.
In a large mixing bowl, thoroughly combine the cream of chicken soup, cream of mushroom soup, cheddar cheese soup, and salsa. Add the shredded chicken and mix until the meat is evenly coated with the sauce.
Arrange four tortillas evenly across the base of the prepared casserole dish. Spoon and spread half of the chicken mixture over the tortillas, smoothing it into an even layer.
Add a second layer of four tortillas, followed by the remaining chicken mixture, spreading evenly once more.
Place the final four tortillas over the top, then scatter the shredded cheddar and colby cheeses uniformly across the surface.
Bake uncovered for 30 minutes, or until the top begins to brown slightly and the filling bubbles around the edges.
Once removed from the oven, garnish with the diced tomato and a sprinkling of chopped cilantro before serving.
