Instructions
Set Up: Preheat the oven to 350°F (175°C), and spray a 9×13-inch baking dish with cooking spray.
Layer Love: Start with a layer of chile peppers, followed by a sprinkle of half the cheeses. Repeat.
Whisk Away: In a separate bowl, combine eggs, evaporated milk, and flour. Thin with milk if desired, then pour over the layered ingredients.
Baking Bliss: Bake for 25 minutes, add tomato sauce, and bake for 15 more minutes.
Cheesy Finish: Turn on the broiler, add remaining cheeses, and broil until melted (2-3 minutes).
Serve and Savor: Dish up your casserole and enjoy the comforting flavors!
Notes
Switch up the flavors by using enchilada sauce instead of tomato sauce.
