Ingredients:

For the Casserole:

• 3 cups cooked, shredded chicken
• 3 ½ cups shredded Mexican cheese
• 1 tablespoon taco seasoning
• 15 corn tortillas (6 inches)
• 1 cup frozen corn kernels, thawed
• ½ teaspoon salt
• ½ cup diced green chiles
• 2 cups black beans, drained and rinsed

For the Enchilada Sauce:

• 2 tbsp vegetable oil (or olive oil)
• 1 small yellow onion, diced
• 1 ½ tsp ground cumin
• 1 ½ tsp chili powder
• 1 tbsp all-purpose flour
• ¼ tsp dried oregano
• 2 cups tomato sauce
• 1 cup chicken broth
• 2 cloves garlic, minced
• Salt to taste (start with about ½ tsp and adjust as needed)

Step 1: Make the Enchilada Sauce

This homemade enchilada sauce adds an authentic flavor and can be adjusted to your desired spice level!

1. Heat the oil in a medium saucepan over medium heat. Add the diced onion and cook until softened, about 3-4 minutes.
2. Add the garlic and cook for another 30 seconds until fragrant.
3. Stir in the flour, cumin, chili powder, and oregano, cooking for about 1 minute to form a thick paste.
4. Slowly pour in the tomato sauce and chicken broth, whisking constantly to avoid lumps.
5. Bring to a simmer and let cook for about 10 minutes, stirring occasionally until the sauce thickens slightly.
6. Season with salt to taste, adjusting as needed. Set the sauce aside to cool slightly.

Step 2: Prepare the Casserole Filling

1. In a large bowl, mix salt, diced green chiles, corn, black beans, shredded chicken, and ½ cup of the enchilada sauce. Stir until everything is well combined and coated in the sauce.

Step 3: Assemble the Casserole (Oven Method)

1. Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with a bit of oil or cooking spray.
2. Spread a thin layer of the enchilada sauce on the bottom of the baking dish.
3. Layer 5 tortillas across the bottom of the dish, tearing them as needed to fit.
4. Spread half of the chicken mixture evenly over the tortillas, then pour about 1/3 of the enchilada sauce on top. Sprinkle with a bit of cheese.
5. Repeat the layering with another 5 tortillas, the remaining chicken mixture, and another 1/3 of the sauce.
6. Place the final layer of 5 tortillas on top and pour the remaining sauce evenly over everything. Sprinkle the remaining shredded cheese on top.
7. Bake uncovered for 22-25 minutes, until the cheese is bubbly and golden.
8. Let it cool for about 10 minutes before serving. Garnish with your favorite toppings, like chopped cilantro, sour cream, or avocado slices.

Step 4: Slow Cooker Method

1. Grease the inside of your slow cooker with oil or cooking spray.
2. Spread a thin layer of the enchilada sauce on the bottom.
3. Layer 5 tortillas at the bottom of the slow cooker, tearing them as needed to fit.
4. Add half of the chicken mixture on top of the tortillas, followed by about 1/3 of the enchilada sauce and a sprinkle of cheese.
5. Repeat with another layer of 5 tortillas, the remaining chicken mixture, another 1/3 of the sauce, and some more cheese.
6. Place the final 5 tortillas on top and pour the remaining enchilada sauce evenly over everything. Sprinkle the remaining cheese on top.
7. Cook on low for 4-5 hours, or until everything is heated through and the cheese is melted and bubbly.
8. Serve warm with any toppings you like!
