Preheat oven to 375°F and spray a 9×13-inch baking dish with nonstick spray.
Spread a few spoonfuls of enchilada sauce in the bottom of the baking dish. Top with a layer of tortillas, breaking some tortillas in half in needed to create an even layer.
Top with 1/3 of the beans, 1/3 of the chicken, 1/3 of the enchilada sauce, and 1/3 of the cheese. Repeat layers — tortillas, beans, chicken, sauce, and cheese — with remaining ingredients.
Cover dish with aluminum foil that’s been coated with nonstick spray and bake 25 minutes. Uncover and bake until cheese is bubbly and starting to brown, 5-10 minutes more.
