This is one of those weeknight heroes that feels like a reward. It layers tender shredded chicken, tortillas, enchilada sauce and melty cheese into a simple, forgiving bake that feeds a crowd — or becomes several lunches. I turn to this casserole when I want dinner ready with a single hands-off oven stretch and reliable, comforting flavor.
There’s no complicated prep. Most of the work is assembling: layering tortillas, chicken tossed with sauce and spices, cheese, repeat. It finishes with a quick bake and a ten-minute rest so the layers set. The result cuts clean, holds well, and slices into tidy squares that reheat beautifully.
Below you’ll find exactly what you need, how to assemble it step-by-step from the recipe source, and practical notes to help it turn out every time. Read the equipment and storage sections before you get started — they’ll save you time and trouble.
What You’ll Gather

Ingredients
- 1½ pounds shredded cooked chicken — the casserole’s protein; use a rotisserie bird or leftover roast for speed and flavor.
- 15 ounces red enchilada sauce (divided) — provides moisture and the dish’s signature tangy, slightly smoky base; reserve part to top the bake.
- 1 ounce taco seasoning — adds Mexican-inspired spice without extra measuring; mix into the chicken for balanced flavor.
- ¼ cup chopped cilantro — folded into the chicken to brighten the filling; some for garnish is nice too.
- 18 (6-inch) flour tortillas — the layers that mimic enchiladas inside a casserole; you’ll use three layers of six tortillas each.
- 3 cups shredded Mexican cheese blend (divided) — melty, savory binder; divided so the topping and middle layers get equal cheese coverage.
- Chopped tomatoes — fresh garnish for contrast and brightness when serving.
- Sliced avocado — adds creaminess and a cooling counterpoint to the sauce.
- Crumbled Cotija cheese — salty finish; sprinkle over the top after baking.
- Fresh cilantro — extra for garnish to lift the dish and give color.
Chicken Tortilla Casserole Made Stepwise
- Preheat oven to 350°F. Spray a 9×13-inch baking dish with nonstick spray and set it aside.
- In a large bowl, combine the 1½ pounds shredded cooked chicken, ¾ of the 15 ounces red enchilada sauce, the 1 ounce taco seasoning, and the ¼ cup chopped cilantro; stir until evenly mixed.
- Divide the 18 (6-inch) flour tortillas into three groups of six tortillas.
- Place six tortillas in a single layer on the bottom of the prepared baking dish, overlapping as needed so the bottom is covered.
- Spread half of the chicken mixture evenly over the first tortilla layer. Sprinkle 1 cup of the 3 cups shredded Mexican cheese blend over the chicken.
- Place the next six tortillas in a single layer on top of the cheese.
- Spread the remaining half of the chicken mixture evenly over the second tortilla layer. Sprinkle another 1 cup of the shredded Mexican cheese blend over the chicken.
- Place the final six tortillas in a single layer on top. Pour the remaining enchilada sauce over the top tortilla layer and spread it evenly. Sprinkle the remaining 1 cup of shredded Mexican cheese blend over the sauce.
- Cover the dish tightly with foil and bake for 35 minutes.
- Remove the foil and bake uncovered for an additional 10 minutes, until the cheese on top is melted and bubbly.
- Remove the casserole from the oven and let it rest for 10 minutes. Top with chopped tomatoes, sliced avocado, crumbled Cotija cheese, and fresh cilantro before slicing and serving.
Why This Recipe Belongs in Your Rotation

This casserole strikes a rare balance: comfort-food satisfaction with low-effort assembly. It’s great for busy weeknights because much of the heavy lifting can be done ahead — shred the chicken and mix the filling in the morning or the day before. The layered format scales up or down easily. Double the recipe in two pans for a potluck, or halve it for smaller households.
Flavor-wise, it’s crowd-pleasing without being cloying. The enchilada sauce keeps the casserole saucy and flavorful, the taco seasoning gives a consistent backbone, and the cheese brings everything together. Fresh tomato, avocado and Cotija on top turn each bite lively and balanced.
Low-Carb/Keto Alternatives

There are straightforward swaps to reduce carbs without changing the process. Use low-carb tortillas in place of the 6-inch flour tortillas to keep the same layering method and baking time. If you prefer to avoid tortillas entirely, make thin layers of roasted thin-sliced zucchini or eggplant as the separators — the texture will be different, but the layering and bake work the same.
For cheese, stick with the Mexican blend or swap in full-fat cheddar and Monterey Jack for similar meltability. Keep the enchilada sauce — low-carb versions exist, or look for a sugar-free label. Skip the tomatoes as a garnish if you’re tracking carbs closely and rely on avocado and cilantro for freshness.
Before You Start: Equipment
Gather these simple items before you begin. It speeds the assembly and keeps everything moving.
- 9×13-inch baking dish — this recipe is sized for that exact pan; it ensures even layering and baking.
- Nonstick spray — you’ll coat the dish so the tortillas don’t stick when you slice and serve.
- Large mixing bowl — for combining the shredded chicken, enchilada sauce, taco seasoning and cilantro.
- Foil — to cover the casserole during the first bake so it heats through without drying out.
- Sharp knife and cutting board — for chopping tomatoes, avocado and extra cilantro for garnish.
Mistakes Even Pros Make
Skipping the rest time. Pulling the casserole straight from the oven and slicing immediately makes a sloppy, runny result. Let it rest the full 10 minutes so layers settle and slices hold together.
Overlapping tortillas haphazardly. You should overlap to cover the bottom, but keep the layer relatively flat so you don’t end up with high ridges that lead to uneven baking. Also, don’t skimp on spreading the enchilada sauce on top — it seals the top tortilla and helps the cheese melt smoothly.
Using cold shredded chicken straight from the fridge. If the chicken is chilled, mix it briefly with the enchilada sauce to let it come to room temperature a bit before assembly; that helps it heat through evenly in the oven.
Make It Diet-Friendly
Want a lighter version? Swap in shredded breast meat and lower-fat cheese to reduce calories and fat. Use less cheese on the middle layers and reserve a modest amount for the top — the dish still binds and tastes satisfying with a leaner profile. Serve smaller portions and bulk the plate up with a big green salad or grilled vegetables on the side.
For a vegetarian take, omit the chicken and substitute a pan of seasoned black beans or a cooked lentil mix seasoned with the taco seasoning. Keep the rest of the assembly identical; the bake time remains the same.
Insider Tips
- Warm tortillas slightly before layering — a quick pass in a warm skillet or a few seconds in the microwave makes them more pliable and reduces cracking.
- Stir the chicken mixture gently but thoroughly so every bite has sauce and seasoning. You want even coverage — not dry pockets.
- If your enchilada sauce is thick, thin the reserved portion with a tablespoon of water to make it easier to spread across the final tortilla layer.
- Use a sharp serrated knife to slice the casserole cleanly after the 10-minute rest. Press down once with the blade, then saw gently to avoid squishing the layers.
Storing, Freezing & Reheating
Cool the casserole completely before refrigerating to avoid soggy condensation. Store in an airtight container or cover the dish tightly with foil. It keeps well in the fridge for 3–4 days and reheats in the oven at 350°F until warmed through, about 15–20 minutes for individual portions, longer for the whole dish.
To freeze, wrap the assembled but unbaked casserole tightly in two layers of foil and freeze up to 2 months. Bake from frozen: remove any plastic, bake covered at 350°F for about 45–55 minutes, then uncover and finish until the top is bubbly and golden. If thawed overnight in the fridge, bake covered for 30–35 minutes and then uncovered for 10 minutes as the recipe directs.
Your Top Questions
Can I use corn tortillas?
Yes, but corn tortillas are more fragile and can crumble when layered. Warm them until pliable and consider lightly frying or toasting each briefly so they hold up. The flavor will be slightly different and more corn-forward.
Do I have to use store-bought enchilada sauce?
No. Homemade sauce works beautifully, and you can control heat and salt that way. If you use homemade, match the consistency to store-bought so the casserole bakes and spreads the same.
Can I prep this ahead?
Absolutely. Assemble the casserole the night before, cover tightly, and refrigerate. Add the final cheese layer and more sauce right before baking if you want a fresher top, or bake straight from the fridge but add a few extra minutes to the covered bake time.
