Cinco de Mayo is just around the corner, and if you’re planning a celebration, this easy chicken enchilada casserole makes a perfect centerpiece. It combines saucy chicken, beans, corn, green chilies, and wilted greens layered between corn tortillas and plenty of melted cheese—think of it as an enchilada lasagna.
This casserole is ideal for feeding a crowd, prepping ahead, or enjoying as flavorful leftovers.
Description
Chicken enchilada casserole takes classic enchilada flavors and layers them into an easy, comforting bake. Corn tortillas, a homemade (or store-bought) enchilada sauce, tender shredded chicken, beans, corn, greens, and cheese create a satisfying meal that reheats beautifully.
Why make your own enchilada sauce?
The enchilada sauce makes the dish. My doubled homemade gluten-free enchilada sauce is quick to prepare: cook a light roux with oil and flour, whisk in spices, add chicken broth, simmer until thickened, and finish with tomato paste. It takes just a few minutes to come together and lets you control the salt and heat. If you prefer a shortcut, a store-bought sauce you trust works fine—but fresh sauce adds depth you’ll notice.
Ingredient highlights
- Enchilada sauce (I doubled the sauce recipe so the casserole stays saucy)
- Rotisserie chicken — a convenient shortcut that saves time and stress
- Corn tortillas for authentic flavor and gluten-free option
- Pinto or black beans and canned or fresh corn for texture and heartiness
- Spinach or kale for added nutrition, wilted quickly in the pan
- Shredded cheddar or Monterey Jack (or a mix) for gooey, melty layers
I often rely on a precooked rotisserie chicken here because the dish is full of other flavors. Combining scratch elements like the sauce and wilted greens with a little shortcut keeps dinner realistic, balanced, and delicious.
Texture and flavor
Unlike many casseroles that become soggy or dry, this chicken enchilada casserole balances textures: corn provides a subtle pop, beans add creaminess, chicken stays tender, and the tortillas and cheese meld into layered bites. The wilted greens add a light freshness and extra nutrition that’s barely noticeable to picky eaters.
Why choose a casserole over rolled enchiladas?
Rolling enchiladas can feel tedious. Layering a casserole gives you freedom and feeds more people with less fuss. Assembly is simple—spread sauce, layer tortillas, add the filling and cheese, and repeat. It’s easier, faster, and ideal for potlucks, meal prep, or weeknight dinners.
Make-ahead and leftovers
This casserole reheats beautifully and never turns mushy. It keeps well in the refrigerator for up to a week when stored in airtight containers, making it an excellent option for meal prep. Reheat portions in the oven or microwave until warmed through—the sauce stays saucy and the cheese remains satisfying.
Ingredients (overview)
Enchilada sauce (doubled): oil, brown rice flour (or all-purpose), corn or arrowroot starch (for gluten-free), chili powder, garlic powder, salt, cumin, oregano, smoked paprika, optional cayenne, tomato paste, and low-sodium chicken broth.
For the casserole: olive or avocado oil, onion, spinach or kale, garlic, canned green chilies, canned pinto or black beans, canned or fresh corn, 2 1/2 cups shredded cooked chicken, corn tortillas, and 2 1/2 cups shredded cheese (cheddar, Monterey Jack, or a mix).
Optional toppings: chopped green onion, cilantro, extra enchilada sauce, or hot sauce.
Basic instructions
- Preheat the oven to 375°F. Prepare and measure ingredients: drain and rinse beans and corn, chop onion and chicken, and have greens and garlic ready.
- Make the enchilada sauce: whisk flour/starch into heated oil to form a light roux, add spices and cook briefly, whisk in chicken broth and tomato paste, bring to a boil, then simmer 3–5 minutes until slightly thickened. Set aside.
- Cook the vegetables: sauté onion in oil until tender, add greens and cook until wilted, stir in garlic until fragrant, then remove from heat.
- Combine the filling: off heat, stir in green chilies, beans, corn, shredded chicken, and 1 cup of enchilada sauce into the skillet until evenly combined.
- Assemble: spread a layer of sauce in a 9×13 dish, add a layer of corn tortillas, then 1/3 of the chicken mixture and some cheese. Repeat to create about three layers, finishing with cheese on top.
- Bake covered with foil for 25–30 minutes, then remove foil and bake 5–10 more minutes until sauce bubbles and cheese melts.
- Let rest 15–20 minutes before cutting into squares. Garnish with green onions or cilantro if desired.
Notes
Enchilada sauce: Store-bought sauce is a convenient option, but homemade sauce is quick and elevates the dish. You can make the sauce 1–2 days ahead—about 4 cups total are needed for this casserole.
Chicken: Rotisserie chicken is an easy shortcut. Use leftover roasted or poached chicken if preferred.
