Ingredients

Yield: One 9-by-13-inch casserole · 8 servings · Baking dish: 9-by-13-inch

• 2½ cups cooked chicken breast, shredded
• 1 can (15 ounces) black beans, drained and rinsed
• 1 cup frozen corn, thawed
• 1 red bell pepper, diced
• ½ small yellow onion, finely diced
• 2 packed cups baby spinach, roughly chopped
• 20 ounces red enchilada sauce, divided
• 1 teaspoon ground cumin
• ½ teaspoon garlic powder
• 8 small corn tortillas
• 1½ cups shredded reduced-fat Mexican-blend cheese, divided

Instructions

1. Preheat the oven. Heat the oven to 375°F. Lightly coat a 9-by-13-inch baking dish with cooking spray to prevent sticking.
2. Prepare the chicken filling. In a large mixing bowl, combine the shredded chicken, drained black beans, thawed corn, diced red bell pepper, finely diced onion, chopped spinach, cumin, garlic powder, 1 cup of enchilada sauce, and ½ cup of the shredded cheese. Stir until everything is evenly combined.
3. Add the bottom layer of sauce. Spread approximately ½ cup of enchilada sauce over the bottom of the prepared baking dish. This helps keep the tortillas moist and prevents them from sticking.
4. Begin layering the casserole. Arrange four corn tortillas over the sauce, cutting or overlapping them as needed to cover the bottom. Spread half of the chicken and vegetable mixture evenly over the tortillas.
5. Finish the layers. Arrange the remaining four tortillas over the first layer of filling. Spread the remaining chicken mixture evenly on top. Pour the remaining enchilada sauce over the casserole and sprinkle with the remaining 1 cup of shredded cheese.
6. Bake until hot and bubbly. Cover the baking dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for another 10 minutes, until the filling is thoroughly heated, the cheese is melted, and the casserole is bubbling around the edges.
7. Rest and serve. Remove the casserole from the oven and let it rest for 5–10 minutes before cutting into eight portions. This allows the layers to settle and makes serving easier.

Estimated Nutrition Per Serving

Estimated nutrition per serving, based on eight servings and the original recipe estimates. Actual values depend on the brands of enchilada sauce, tortillas, beans, chicken, and cheese used. Any added sugar comes primarily from the enchilada sauce, so check the label. Sodium may also vary considerably among brands, particularly the sauce, cheese, beans, and tortillas.

Why This Recipe Is a Healthy Choice

Chicken breast provides complete protein, which helps support muscle maintenance, repair, and strength. Maintaining muscle becomes especially important as we age, and including protein-rich foods in regular meals is a practical way to support healthy aging. Black beans contribute additional plant-based protein, giving this casserole approximately 24 grams of protein per serving.

Black beans are also an excellent source of dietary fiber, which supports digestive health and helps make meals more satisfying. The corn, bell pepper, onion, spinach, and corn tortillas contribute additional fiber and nutrients. Red bell peppers provide vitamin C, while spinach contributes folate, vitamin K, and carotenoids. Together, these ingredients help provide approximately 6 grams of fiber per serving.

The shredded cheese adds calcium, protein, and satisfying fat, while the enchilada sauce, cumin, and garlic provide plenty of savory flavor. Choosing reduced-fat cheese helps keep the casserole flavorful without requiring a large amount of added fat. With protein, vegetables, beans, and a modest amount of cheese in every serving, this recipe is a practical way to combine several nutritious food groups in one dish.

This casserole is also a great example of the LifesYearning Complete in 3 approach: protein from chicken and beans, fiber from beans and vegetables, and satisfying fat from cheese. It’s a delicious, convenient meal that doesn’t require complicated preparation or several additional side dishes.

Cooking Notes

Use cooked shredded chicken: Leftover chicken breast or plain rotisserie chicken makes this recipe especially convenient. Shred or chop the chicken into small pieces so it distributes evenly throughout the casserole.

Rinse the black beans: Draining and rinsing canned black beans removes some of the excess sodium and canned liquid. This also helps keep the filling from becoming overly wet.

Chop the vegetables finely: Dice the onion and red pepper into small pieces so they soften during baking. Roughly chopping the spinach helps it distribute throughout the chicken mixture instead of forming large clumps.

Use the enchilada sauce in layers: The sauce is divided between the filling, the bottom of the baking dish, and the top of the casserole. This helps keep the corn tortillas moist and distributes that familiar enchilada flavor throughout the dish.

Choose your favorite enchilada sauce: Red enchilada sauces vary in heat, added sugar, and sodium. Choose a mild sauce if you prefer less spice, or a medium or hot sauce for a bolder flavor. Checking the nutrition label is especially helpful if you’re watching sodium.

Allow the casserole to rest: Letting the casserole stand for 5–10 minutes after baking helps the layers settle. It will be easier to cut into portions and serve without the filling falling apart.

Make-ahead option: Assemble the casserole in advance, cover, and refrigerate until ready to bake. If baking directly from the refrigerator, allow a few additional minutes and make sure the center reaches 165°F.

Even better the next day: The flavors continue to blend as the casserole rests, making the leftovers especially delicious. This is an excellent recipe to prepare once and enjoy for several lunches or dinners throughout the week.

Storage and freezing: Refrigerate leftovers promptly in an airtight container for 3–4 days. Freeze individual portions for up to 2–3 months for best quality. Thaw in the refrigerator and reheat until the center reaches 165°F.

Serving suggestions: This casserole is substantial enough to enjoy on its own. If you’d like to add something fresh, serve it with sliced avocado, a green salad, chopped cilantro, or a spoonful of plain Greek yogurt. Optional toppings are not included in the estimated nutrition.
