Creating Pastel Azteca is a breeze if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Baking Dish: Grease a 9×13-inch baking dish lightly with cooking spray or oil.
3. Layer the Tortillas: Place a layer of corn tortillas at the bottom of the baking dish, overlapping them slightly.
4. Spread Refried Beans: Evenly spread a layer of refried beans over the tortillas.
5. Add Chicken: Sprinkle half of the shredded chicken evenly over the beans.
6. Add Salsa: Pour a third of the salsa over the chicken layer.
7. Add Cheese: Sprinkle 1 cup of shredded cheese over the salsa layer.
8. Repeat Layers: Repeat the layering process (tortillas, beans, chicken, salsa, cheese) until all ingredients are used, finishing with tortillas topped with salsa and remaining cheese.
9. Cover with Foil: Cover the dish with aluminum foil to prevent burning.
10. Bake: Place in the preheated oven and bake for 25-30 minutes.
11. Uncover: Remove the foil and bake for an additional 10-15 minutes, until the cheese is bubbly and golden.
12. Cool: Allow to cool for a few minutes before slicing into servings.
