Ingredients
- Cooked shredded chicken breast provides lean protein while soaking up all the delicious sauce flavors
- Green chile enchilada sauce delivers authentic Mexican flavor without any work
- Chopped green chiles add a mild heat and distinctive southwestern tang
- Monterey Jack cheese melts perfectly creating that irresistible cheese pull
- Sour cream creates richness and balances the green chile spice
- Tortillas either flour or corn depending on your preference both work beautifully
- Fresh toppings including cilantro green onions and tomatoes add brightness and color
Step-by-Step Instructions
- Prepare the oven
- Set your oven to 425°F ensuring it's fully preheated before baking. This high temperature helps achieve that golden bubbly cheese topping that makes this casserole irresistible.
- Mix the filling
- Combine the shredded chicken with half of the enchilada sauce chopped green chiles and half of the cheese. This creates a moist flavorful filling where every bite contains the perfect balance of ingredients. Make sure to mix thoroughly so the flavors distribute evenly.
- Create the cream sauce
- Stir together the remaining enchilada sauce with sour cream until completely smooth. This combination creates the signature creamy tang that makes these enchiladas special. Pour half of this mixture into your baking dish creating a base that prevents sticking.
- Roll the enchiladas
- Take each tortilla and place a generous portion of chicken filling down the center. Roll it up tightly and place seam side down in the baking dish. Continue until all tortillas are filled arranging them snugly in the dish to maintain their shape during baking.
- Add the final toppings
- Pour the remaining sauce over the rolled tortillas ensuring they're completely covered to prevent drying out. Sprinkle the remaining cheese evenly across the top creating a blanket that will melt into golden perfection.
- Bake to bubbly perfection
- Place the casserole in your preheated oven and bake for exactly 25 minutes. You'll know it's done when the edges are bubbling and the cheese has turned a beautiful golden color with some slightly darker spots.
- Garnish and serve
- Top with fresh cilantro green onions and diced tomatoes right before serving. These fresh elements contrast beautifully with the rich casserole providing color texture and brightness.

The green chiles are truly the star of this dish. My grandmother from New Mexico taught me that the Hatch variety offers the perfect balance of flavor and mild heat. Whenever I make this casserole the aroma takes me back to her kitchen where I first learned to appreciate the distinctive taste of southwestern cooking.
Make Ahead Options
This enchilada casserole works beautifully as a make-ahead meal. You can assemble the entire casserole up to 24 hours before baking just cover tightly with foil and refrigerate. When ready to cook remove from the refrigerator while the oven preheats then add about 10 minutes to the baking time since you're starting with a cold dish. The flavors actually develop and improve with a bit of resting time.
Storage and Reheating
Once cooled this casserole stores beautifully in the refrigerator for up to 3 days in an airtight container. For best reheating results place portions in a 350°F oven for 15 minutes rather than using the microwave which can make the tortillas soggy. If freezing portion into individual servings and wrap tightly in plastic wrap then foil. Thaw overnight in the refrigerator before reheating for best texture and flavor.
Customization Ideas
This basic recipe welcomes countless variations to suit your taste preferences or what you have on hand. Try adding a layer of black beans between the tortillas for extra protein and fiber. Diced bell peppers sautéed with the chicken add color and nutrition. For heat lovers mix in diced jalapeños or a dash of hot sauce to the chicken filling. You can even transform this into a breakfast dish by adding scrambled eggs to the filling mixture.
Serving Suggestions
While delicious on its own this enchilada casserole pairs beautifully with simple sides. A crisp green salad with lime vinaigrette offers refreshing contrast to the rich casserole. Mexican rice soaks up any extra sauce making for a complete meal. For casual entertaining set up a toppings bar with additional sour cream diced avocado hot sauce and pickled jalapeños letting guests customize their portions.

Commonly Asked Questions
- → Can I make this enchilada casserole ahead of time?
Yes! Assemble the casserole up to 24 hours in advance, cover tightly with plastic wrap, and refrigerate. When ready to bake, remove from the refrigerator 30 minutes before baking and add an extra 5-10 minutes to the baking time.
- → Can I freeze this green chile chicken enchilada casserole?
Absolutely! Assemble the casserole without the final topping of cilantro, green onions, and tomatoes. Wrap tightly in plastic wrap and aluminum foil and freeze for up to 3 months. Thaw overnight in the refrigerator before baking and add 10-15 minutes to the baking time.
- → What sides go well with chicken enchiladas?
Mexican rice, refried beans, a simple green salad, or corn salad make excellent side dishes. For a lighter option, serve with roasted vegetables or a cabbage slaw with lime dressing.
- → Can I use corn tortillas instead of flour tortillas?
Yes! Both work wonderfully. Corn tortillas offer a more authentic flavor and are naturally gluten-free. To prevent cracking, warm them slightly before rolling. Flour tortillas are easier to work with and stay softer after baking.
- → How spicy is this enchilada casserole?
This casserole is mild to medium in spice level, depending on the green chile enchilada sauce you choose. For a spicier version, add diced jalapeños or use hot green chiles. To reduce spiciness, use mild sauce and rinse the green chiles before adding.
- → Can I add vegetables to this enchilada casserole?
Definitely! Sautéed bell peppers, zucchini, corn, or spinach make excellent additions. Mix them with the chicken filling or layer between the tortillas for added nutrition and flavor.
