The recipe started as a way to reinvent leftover chipotle grilled chicken thighs. It’s essentially assembly and bake—no rolling tortillas required. I made individual casseroles here, but you can easily layer everything in a larger casserole dish for a family-style meal. The result is melty, savory, and satisfying.

Why an Enchilada Casserole

I love enchiladas, but assembling rolled enchiladas at home—especially with corn tortillas—can be time-consuming: warming, filling, and rolling each tortilla. This layered enchilada casserole streamlines the process, similar to making a lasagna. It saves time while delivering the same comforting flavors.

Ingredients for 5-Ingredient Enchilada Casserole

True to its name, this casserole uses only a handful of ingredients. The basic components are:

• Corn tortillas
• Cooked chicken thighs (shredded or diced)
• Baby spinach
• Mexican cheese blend, shredded
• Red enchilada sauce

If you prefer substitutions, try:

• Rotisserie chicken instead of cooked thighs
• Flour tortillas in place of corn
• Colby Jack or other melty cheeses
• Homemade enchilada sauce

Substitutes for Chicken Thighs

If chicken thighs aren’t available or desired, this casserole adapts well to other proteins. Try lean ground beef (92/8) or ground turkey (93/7) for a similar texture. For a vegetarian option, use tofu, crumbled tempeh, or sautéed portobello mushrooms. Any of these choices will work with the same layering method and sauce.

No matter which protein you choose, the dish remains flavorful and easy to prepare.

How to Make 5-Ingredient Chicken Enchilada Casserole

Prep is fast. Start by preheating the oven to 375°F (190°C).

Heat a large skillet over medium-high heat. While it warms, shred the cooked chicken and slice or roughly chop the spinach. Lightly spray the skillet with cooking spray, then add the chicken and spinach. Stir until the spinach wilts. Add 1/4 cup enchilada sauce and 1/4 cup shredded cheese, bring to a gentle simmer, then remove from heat and set aside.

In each casserole dish, spread about 1 tablespoon of enchilada sauce on the bottom. Place one corn tortilla on top, sprinkle a little cheese, and add a portion of the chicken-spinach mixture. Top with a second tortilla, pour another 1/4 cup of sauce over it, and finish with the remaining shredded cheese. Repeat to make two individual casseroles, or layer repeatedly in a larger dish for more servings.

Place the casserole dishes on a baking sheet and bake in the preheated oven for approximately 12–15 minutes, or until the cheese is melted and golden. Remove from the oven and add your favorite toppings if desired. Nutrition facts vary by serving size and ingredient choices.
