Always a hearty family favorite, Chicken Tortilla Casserole makes the most of convenient ingredients while packing tons of rich flavor in every creamy bite!
Preheat oven to 350 °F (177 °C). Spray a 9X13 inch baking dish with nonstick cooking spray.
In a large skillet, heat vegetable oil (2 tablespoons) then saute onion (1 cup) and garlic (4 cloves) until soft and translucent. Add the cumin (1 1/2 teaspoons), oregano (1 1/2 teaspoons), and black pepper (1/2 teaspoon), and cook for about 1 minute, stirring constantly. Add chilies (2 cans), including the juice, both soups, and chicken broth (1 cup), and whisk until the mixture is combined and smooth.
Pour 1/2 cup of the sauce on the bottom of the baking dish. Spread 1/3 flat of tortillas in a flat layer on top, 1/3 of the remaining sauce, 1/2 the chicken, 1/3 of the cheese.
Continue with the second layer of 1/3 of tortillas, 1/3 of the sauce, the remainder of the chicken, 1/3 of the cheese.
Finish with the third and last layer with the remaining the tortillas, the sauce, and the cheese.
Bake in the preheated oven, uncovered, for 35-45 minutes or until heated through the center and sauce is bubbly.
