Equipment

Large skillet
Mixing bowl
Aluminum foil

Instructions

Step 1: Preheat the Oven

Preheat the oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish.

Step 2: Cook the Onion

Heat the olive oil in a large skillet over medium heat.

Add the sliced onion and cook for 8–10 minutes, stirring occasionally, until soft and lightly caramelized.

Step 3: Prepare the Filling

Add to the skillet:

Shredded chicken
Green chiles
Garlic powder
Cumin
Chili powder
Smoked paprika
Salt
Black pepper

Cook for 3–4 minutes, stirring until heated through.

Remove from the heat.

Stir in:

1 cup Monterey Jack cheese
1 cup cheddar cheese
Cilantro (if using)

Mix until evenly combined.

Step 4: Prepare the Sauce

In a bowl, whisk together:

Green enchilada sauce
Sour cream

Spread about ½ cup of the sauce evenly over the bottom of the prepared baking dish.

Step 5: Assemble the Enchiladas

Spoon about ⅓ cup of the chicken filling into each tortilla.
Roll tightly and place seam-side down in the baking dish.
Repeat with the remaining tortillas.

Pour the remaining green enchilada sauce evenly over the enchiladas.

Sprinkle with:

1½ cups Monterey Jack cheese
½ cup cheddar cheese

Step 6: Bake

Cover the dish loosely with foil.

Bake for 20 minutes.

Remove the foil and bake for another 10 minutes, or until the cheese is melted, bubbly, and lightly golden.

Let the enchiladas rest for 5–10 minutes before serving.

Storage

Refrigerator

Store leftovers in an airtight container for up to 4 days.

Freezer

Wrap tightly and freeze (before or after baking) for up to 3 months.

Thaw overnight in the refrigerator before reheating.

Reheating

Bake at 350°F (175°C) for 20–25 minutes, or microwave individual portions until heated through.

Tips for Success

Rotisserie chicken makes this recipe quick and convenient.
Lightly warm corn tortillas before rolling to prevent cracking.
Don’t overfill the tortillas, or they’ll be difficult to roll.
Let the enchiladas rest after baking so they hold their shape when served.
For extra flavor, roast fresh green chiles instead of using canned ones.

Variations

Vegetarian Version

Replace the chicken with black beans, corn, sautéed mushrooms, and spinach.

Southwest Style

Add 1 cup of corn kernels and 1 can of drained black beans to the filling.
