This healthy chicken taco casserole brings together all my family’s favorite taco night flavors in one easy dish that warms bellies and feels extra cozy for weeknights or gatherings. It is a lighter casserole loaded with veggies beans and hearty protein while still tasting completely comforting. My kids always ask for seconds and it has become our go to for busy days after a hectic work schedule.
The first time I created this recipe I wanted a crowd pleasing dinner that used up leftover chicken and stuck to our healthy eating goals. It was love at first bite and now I make double batches ahead of family visits.

Step-by-Step Instructions
- Prepare the Baking Dish:
- Lightly grease a nine by thirteen inch baking dish with olive oil spray to ensure easy removal and golden edges
- Sauté the Aromatics:
- Heat olive oil in a skillet over medium high then add minced garlic sauté just for one minute so it becomes fragrant but not browned add diced onion red and green peppers and cook stirring occasionally for about five minutes until softened and beginning to caramelize
- Build the Bean Mixture:
- Add drained black beans and taco seasoning to the skillet stir everything together and cook for one extra minute to bloom the spices fully coat the peppers and onion and ensure the beans are heated through then remove from the heat
- Layer the Casserole:
- Place two tortillas covering the bottom of the baking dish overlap as needed for a sturdy base evenly spread half of the sautéed bean and veggie mixture over the tortillas top with about half of the shredded chicken drizzle half the enchilada sauce across the layer and sprinkle half the cheese over everything
- Repeat and Top:
- Add the remaining two tortillas on top repeating another layer with the rest of the bean mixture chicken enchilada sauce and finish with a thick cover of remaining cheese for a golden bubbly finish

Each time I pull this casserole out of the oven the smell alone brings my family running. Using homemade enchilada sauce and extra fresh bell peppers always makes it a little extra special and reminds me of my grandmother’s love for vibrant colorful dinners.
Storage Tips
You can refrigerate any leftovers from this dish for three to four days in an airtight container the flavors continue to meld and it is easy to reheat in the oven or microwave. For longer keeping let the casserole cool completely before freezing slices wrapped well in parchment. Thaw overnight in the fridge for best texture.
Ingredient Substitutions
For the protein you can swap in shredded rotisserie turkey or cooked lean ground beef if you prefer a different flavor profile. Vegetarian friends can skip the chicken entirely and add more beans or even some cooked quinoa. Monterey Jack or cheddar makes a good cheese stand in if you do not have a Mexican blend handy.
Serving Suggestions
Serve as a main dish paired with a crisp salad like a jicama slaw or citrus greens for both texture and a burst of freshness. I love topping each square with a dollop of Greek yogurt a little salsa or diced avocado to bring both creaminess and color to the plate.
Cultural Context
This dish borrows inspiration from Tex Mex casseroles found in Southwest kitchens where families mix tortillas beans and chicken with zesty sauces for cozy meals. Layering the tortillas is similar to how enchiladas are built in Mexican home kitchens but the baking pan method makes serving and sharing so much easier for busy nights.

I learned the importance of layering sauce next to tortillas to keep everything moist and flavorful so every bite is equal parts tender and satisfying. Once you taste the mix of melted cheese and spiced veggies you will understand why this recipe is a keeper for both weeknights and potlucks.
