Full Ingredients

For the Chicken Enchilada Casserole

• 3 cups cooked shredded chicken (about 1 1/2 lb; rotisserie chicken works very well)
• 10–12 small (6-inch) corn tortillas (or flour tortillas, if you prefer)
• 2 (14 oz) cans red enchilada sauce (about 3 1/2 cups), divided
• 3 cups shredded Mexican blend cheese (about 12 oz), divided
• 1 small yellow onion, finely diced (about 1 cup)
• 2 cloves garlic, minced
• 1 (4 oz) can mild diced green chiles, drained
• 2 tbsp olive oil or neutral cooking oil
• 1 tsp ground cumin
• 1 tsp chili powder
• 1/2 tsp smoked paprika (optional but recommended)
• 1/2 tsp kosher salt, plus more to taste
• 1/4 tsp freshly ground black pepper
• Nonstick cooking spray or a little extra oil for greasing the baking dish

For Serving & Garnish (Optional but Delicious)

• 1/4 cup chopped fresh cilantro
• 1–2 green onions, thinly sliced
• 1–2 fresh jalapeños, thinly sliced (remove seeds for less heat)
• 1 lime, cut into wedges
• 1/2 cup sour cream or Mexican crema
• 1 ripe avocado, sliced or diced
• 1/4 cup crumbled queso fresco or cotija cheese (optional)

Step-by-Step Instructions

Step 1: Preheat the oven and prepare your pan

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with nonstick cooking spray or a thin film of oil. This helps prevent sticking and makes cleanup much easier.

Gather and measure all of your ingredients. Shred the cooked chicken (if it is not already shredded), dice the onion, mince the garlic, and drain the canned green chiles. Having everything ready before you start cooking will make the process smooth and stress-free.

Step 2: Sauté the aromatics for the filling

In a large skillet set over medium heat, add the 2 tbsp oil. Once the oil is shimmering, add the diced onion and cook, stirring occasionally, for 5–6 minutes, until the onion is soft and translucent.

Add the minced garlic and cook for another 30–60 seconds, just until fragrant. Be careful not to brown or burn the garlic, as it can turn bitter.

Step 3: Build the chicken enchilada filling

To the skillet with the softened onion and garlic, add the ground cumin, chili powder, smoked paprika, salt, and black pepper. Stir for about 30 seconds to lightly toast the spices; this wakes up their flavor.

Stir in the drained diced green chiles, then add the shredded chicken. Toss everything together so the chicken is coated in the spice mixture and aromatics. Cook for 2–3 minutes, just until the chicken is warmed through. Taste and adjust seasoning with a pinch more salt or pepper if needed, then turn off the heat and set the skillet aside.

Step 4: Warm the tortillas and get the sauce ready

Pour the enchilada sauce into a large measuring cup or bowl so it is easy to ladle. You will use roughly 1/2 cup for the bottom of the dish, and about 1 cup for each of three layers (first layer, second layer, and top).

To prevent cracking and make layering easier, warm the tortillas. You can wrap them in a slightly damp paper towel and microwave in 20–30 second bursts until just pliable, or quickly warm them in a dry skillet over medium heat for about 20 seconds per side. Stack the warmed tortillas on a plate and cover with a clean kitchen towel to keep them soft.

Step 5: Assemble the first layers

Spread 1/2 cup of enchilada sauce evenly over the bottom of the greased 9×13-inch baking dish.

Lay down a layer of tortillas: use about 3–4 tortillas, tearing them in half if needed, to create a mostly even layer that covers the sauce. Overlapping is fine.

Scatter half of the chicken mixture evenly over the tortillas. Sprinkle with 1 cup of shredded cheese. Pour about 1 cup of enchilada sauce over the chicken and cheese, trying to cover as much of the surface as possible.

Step 6: Add remaining layers and top with cheese

Add a second layer of tortillas (again using 3–4), overlapping to cover the filling. Spread the remaining chicken mixture on top, followed by another 1 cup of shredded cheese. Pour another 1 cup of enchilada sauce evenly over this layer.

Finish with a final layer of tortillas. Pour the remaining enchilada sauce (about 1 cup) evenly over the top, making sure it seeps into the corners and edges. Sprinkle the last 1 cup of shredded cheese evenly over the surface.

Step 7: Bake, rest, garnish, and serve

Cover the baking dish tightly with aluminum foil, tenting it slightly so it does not press directly on the cheese. Bake in the preheated 375°F (190°C) oven for 20 minutes.

After 20 minutes, carefully remove the foil and continue baking for another 10 minutes, or until the casserole is bubbling around the edges and the cheese is fully melted and lightly golden in spots. If you like a more deeply browned top, you can broil it on high for an additional 1–2 minutes, watching very closely.

Remove the casserole from the oven and let it rest for 5–10 minutes. This helps it set up so it slices neatly. Just before serving, sprinkle with chopped cilantro, sliced green onions, jalapeño slices, crumbled queso fresco (if using), and serve with lime wedges, sour cream, and avocado on the side. Slice into squares and enjoy.

Pro Tips

• Use rotisserie chicken for speed: A store-bought rotisserie chicken makes this recipe very quick. Simply remove the skin and shred the meat.
• Do not skimp on sauce: The enchilada sauce keeps the tortillas tender and flavorful. Make sure each tortilla layer is well coated to avoid dry spots.
• Let it rest before slicing: The casserole can look very saucy when it first comes out of the oven. Resting for at least 5 minutes helps it firm up and slice cleanly.
• Adjust the spice level: Use hot enchilada sauce or add a pinch of cayenne for more heat, or stick with mild sauce and omit jalapeños for a kid-friendly version.
• Cheese choices: Mexican blend melts beautifully, but a mix of Monterey Jack and sharp cheddar works just as well and adds great flavor.

Variations

• Black bean and corn version: Stir 1 cup canned black beans (rinsed and drained) and 1 cup thawed frozen corn into the chicken mixture for extra fiber and sweetness. You can also reduce the chicken to 2 cups to balance the filling.
• All-vegetable option: Skip the chicken and use a mix of sautéed bell peppers, zucchini, onions, and black beans. You may want to add an extra 1/2 cup of cheese to help it hold together.
• Green enchilada casserole: Swap the red enchilada sauce for green enchilada sauce or salsa verde, and use pepper Jack cheese for a slightly tangier, brighter flavor.

Storage & Make-Ahead

Allow the casserole to cool to room temperature, then cover tightly and refrigerate for up to 4 days. Reheat individual portions in the microwave until hot, or cover the entire dish with foil and warm in a 350°F (175°C) oven for about 20–25 minutes.

For make-ahead, you can assemble the casserole up to the point of baking, cover it tightly, and refrigerate for up to 24 hours. When ready to bake, remove from the fridge while the oven preheats and add an extra 5–10 minutes to the covered baking time.

To freeze, assemble the casserole in a freezer-safe dish, wrap well in plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the refrigerator, then bake as directed, adding 10–15 minutes to ensure it is heated through.
