Preheat oven to 350ºF. In a large bowl, combine the shredded chicken, 1/4 cup enchilada sauce and a generous pinch of salt and pepper. Mix together and taste. Season with more salt and pepper as needed.
If using corn tortillas: Wrap the tortillas in a damp paper towel and heat them in the microwave for 1 minute, flipping the them halfway through until all of them are warm and pliable.If using flour tortillas: Microwave the tortillas on a plate for 1 minute, flipping them halfway through until all of them are warm and pliable.
Assemble the enchiladas by filling each tortilla evenly with the shredded chicken mixture and 1 cup of shredded cheese. Roll the tortillas tightly to close and place in large baking dish seam side down.
Pour the remaining 1 3/4 cup enchilada sauce over the tortillas, top with the remaining 1 1/2 cups shredded cheese, and bake for 20 minutes until the cheese is melted and bubbly.
Serve immediately and garnish with desired toppings.
For the chicken: You can use any leftover chicken you have in the fridge, use a store-bought rotisserie chicken, or you can make your own shredded chicken at home.
If using flour tortillas: Since flour tortillas are often larger than corn tortillas, you will need an additional 1/2 cup cooked shredded chicken for the filling.
To store enchiladas, place them in an airtight container and refrigerate for up to 4 days.
To freeze enchiladas, let them cool completely in the fridge. Transfer the enchiladas to a freezer safe container or freezer bag and freeze. You can also wrap the enchiladas completely in aluminum foil and freeze.
