Honestly, the toppings might be my favorite part.

Ingredients

• cooked shredded chicken
• corn tortillas
• green enchilada sauce
• shredded Monterey Jack or Mexican blend cheese
• diced red onion
• jalapeño
• avocado
• fresh cilantro
• olive oil
• Salt and black pepper

Optional Toppings

• Lime wedges
• Sour cream
• Extra jalapeños
• Hot sauce

The Steps

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9x13 inch baking dish with olive oil.

Step 2: Prepare the Chicken

If your chicken isn’t already shredded, shred it using two forks or your hands.

Season lightly with salt and pepper.

Rotisserie chicken works wonderfully for this recipe and saves time.

Step 3: Layer the Casserole

Spread a thin layer of green enchilada sauce across the bottom of the baking dish.

Place a layer of corn tortillas over the sauce. You may need to cut some tortillas to fit the shape of the dish.

Add a layer of shredded chicken.

Pour some enchilada sauce over the chicken.

Sprinkle with shredded cheese.

Step 4: Repeat the Layers

Repeat the layering process until all ingredients are used, finishing with a generous layer of cheese on top.

Step 5: Bake

Place the casserole in the oven and bake for 25–30 minutes, or until the cheese is melted and bubbly.

If you like a slightly golden top, you can broil it for an additional 1–2 minutes.

Step 6: Add Toppings

Remove the casserole from the oven and let it rest for about 5 minutes.

Top with sliced avocado, diced red onion, jalapeño slices, and chopped cilantro.

Step 7: Serve

Slice into squares and serve warm.

Add a squeeze of lime or a dollop of sour cream if you like.

The Magic of Green Enchilada Sauce

Green enchilada sauce is what makes this dish so special.

Unlike red enchilada sauce, which tends to be richer and deeper in flavor, green enchilada sauce is brighter and slightly tangy thanks to tomatillos and green chilies.

It adds this beautiful freshness to the casserole while still feeling warm and comforting.

You can use your favorite store-bought version to keep things simple, or homemade if you happen to have it on hand.

Either way, it creates that signature enchilada flavor we all crave.

A Layered Casserole That Just Works

Layered casseroles are one of my favorite ways to cook because they’re incredibly forgiving.

You simply stack everything together and let the oven do the work.

In this recipe, the layers look something like this:

• Tortillas
• Shredded chicken
• Green enchilada sauce
• Cheese
• Repeat

As it bakes, the tortillas soften and absorb all the delicious flavors from the sauce and chicken.

Meanwhile, the cheese melts into a golden bubbly layer that brings everything together.

And those crispy edges around the sides of the dish? Absolute perfection.

The Best Toppings

One of the best parts about enchilada casseroles is how customizable they are once they come out of the oven.

This version is finished with:

• Sliced avocado for creaminess
• Fresh cilantro for brightness
• Diced red onion for crunch and sharpness
• Jalapeño slices for a little heat

A squeeze of lime over the top is also a fantastic finishing touch.

These fresh toppings balance the rich, cheesy casserole beautifully.

A Great Meal for Any Night of the Week

This casserole is incredibly versatile.

It’s perfect for:

• Weeknight family dinners
• Meal prepping lunches
• Potluck gatherings
• Game day meals
• Feeding a crowd

You can even assemble it ahead of time and bake it later, which makes it a lifesaver when you’re hosting.

Serve it with a simple salad, Mexican rice, or tortilla chips and guacamole for a full meal.

Optional Variations

This casserole is incredibly easy to customize depending on what you have on hand.

Try adding:

• Black beans
• Corn
• Sautéed peppers
• Cream cheese for extra richness
• Pepper jack cheese for extra heat

You can also swap the chicken for shredded turkey or even roasted vegetables for a vegetarian version.

Storage Tips

Leftovers store beautifully.

Keep the casserole in an airtight container in the refrigerator for up to 4 days.

Reheat individual portions in the microwave or warm larger portions in the oven.

It’s just as delicious the next day.

Final Thoughts

This green chicken enchilada casserole is everything we love about comfort food - warm, cheesy, satisfying, and full of bold flavor.

It’s simple enough for a weeknight dinner but delicious enough to serve to guests.

And those fresh toppings at the end bring the whole dish to life.

Once you try this layered version of enchiladas, you may never go back to rolling them again.
