Ingredients

Scale

For the Sauce:

  • 1 tablespoon olive oil
  • 1 small yellow onion, diced
  • ½ teaspoon kosher salt
  • 1½ teaspoons ground cumin
  • 2 teaspoons chili powder
  • 1 tablespoon all-purpose flour
  • 1 can (15 oz) tomato sauce
  • 1 cup chicken broth
  • 2 garlic cloves, minced

For the Casserole:

  • 3 cups shredded cooked chicken thighs
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 1 can (4.5 oz) diced green chiles
  • 1 can (15 oz) black beans, rinsed and drained
  • 12 corn tortillas (6 inches each)
  • 3 cups shredded Colby Jack cheese

Instructions

1. Prepare the Oven and Baking Dish
Preheat your oven to 350°F. Lightly grease a 9×13-inch baking dish with cooking spray and set it aside.

2. Make the Enchilada Sauce
Heat olive oil in a skillet over medium heat. Sauté diced onion with kosher salt until translucent (about 5 minutes). Stir in cumin and chili powder, cooking for 30 seconds to release their aroma. Add flour and stir to form a roux. Gradually whisk in chicken broth, then add tomato sauce and minced garlic. Simmer for 5 minutes, stirring occasionally. For a smoother sauce, blend it (optional).

3. Prepare the Filling
In a bowl, combine shredded chicken thighs, salt, black pepper, green chiles, and black beans. Mix in ½ cup of the prepared enchilada sauce.

4. Assemble the Casserole
Spread ½ cup of sauce on the bottom of the baking dish. Dip tortillas in the remaining sauce to coat lightly. Layer 6 tortillas on the bottom of the dish. Spread half of the chicken mixture over them and top with 1 cup of cheese. Repeat with another layer of dipped tortillas, chicken mixture, and cheese. Finish with remaining sauce and sprinkle with 2 cups of cheese.

5. Bake
Bake uncovered for 25–30 minutes, or until cheese is bubbly and golden brown around the edges. Let cool for 5 minutes before serving.

Notes

Serving Suggestions: Serve warm with chopped cilantro, sour cream, or sliced avocado on top. Pair with Mexican rice or a crisp green salad for a complete meal.

Tips & Tricks:

  • Dip tortillas in sauce to prevent them from drying out during baking.
  • Taste your enchilada sauce before assembling—adjust seasoning if needed.

Storage & Reheating: Refrigerate leftovers in an airtight container for up to 4 days, or freeze unbaked casserole tightly wrapped for up to 2 months. Reheat individual portions in the microwave for 2 minutes, or bake covered at 350°F for about 20 minutes until warmed through.
