Ingredients

Save

• 3 cups cooked shredded chicken
• 1 can (10 oz) cream of chicken soup
• 1 cup sour cream
• 1 can (10 oz) diced tomatoes with green chilies (Rotel)
• 1 can (15 oz) black beans, drained and rinsed
• 1 cup frozen corn
• 2 cups shredded cheddar or Mexican blend cheese
• 1 teaspoon chili powder
• 1 teaspoon cumin
• 8 small corn tortillas, cut into halves or quarters
• 2 tablespoons chopped fresh cilantro (optional)
• Salt and pepper to taste

How to Make It Step-by-Step

1. Preheat the oven: Set your oven to 350°F (175°C) to ensure it’s ready to bake your casserole. Lightly grease a 9×13-inch baking dish to prevent sticking.
2. Prepare the chicken mixture: In a large bowl, combine the shredded chicken, cream of chicken soup, sour cream, diced tomatoes with green chilies, black beans, corn, chili powder, cumin, and a pinch of salt and pepper. Stir everything together until the ingredients are well combined into a creamy, flavorful mixture.
3. Layer the casserole: Start by spreading a thin layer of the chicken mixture at the bottom of the prepared baking dish. Then, layer half of the tortilla pieces on top of the chicken mixture. Add half of the remaining chicken mixture and sprinkle half of the shredded cheese.
4. Repeat the layers: Place the second layer of tortillas, followed by the rest of the chicken mixture and the remaining cheese. This creates a hearty, layered casserole that’s packed with flavor in every bite.
5. Bake: Cover the casserole with foil and bake for 25 minutes. After that, remove the foil and bake for an additional 10-15 minutes, or until the cheese is golden and bubbly.
6. Rest and serve: Once out of the oven, let the casserole rest for 5 minutes to set. This makes it easier to cut into neat, hearty servings. Garnish with chopped fresh cilantro for a pop of color and flavor. Serve warm and enjoy!

Tips for Best Results

• Use rotisserie chicken: To make this meal even quicker, use rotisserie chicken. It’s flavorful and saves you time on prep. Just shred it and mix it in with the other ingredients!
• Don’t skip the foil: Covering the casserole with foil while baking ensures that the dish cooks evenly, keeping everything moist and tender. You can uncover it in the last few minutes for that golden, bubbly top layer of cheese.
• Adjust seasoning: The salsa and taco seasoning already add a lot of flavor, but don’t be afraid to taste the mixture and adjust the seasoning with a bit more chili powder, cumin, or even some garlic powder if you want extra kick.
• Let it rest: Allowing the casserole to rest for a few minutes after baking helps the layers set and makes it easier to cut. Plus, it gives the flavors a moment to settle.

Ingredient Substitutions & Variations

• Vegetarian: If you’re looking for a vegetarian option, simply replace the chicken with black beans, corn, and bell peppers. You can also add some sautéed mushrooms for extra flavor.
• Low-carb version: For a keto meal plan, replace the tortillas with thin slices of zucchini or low-carb tortillas to keep it low-carb while still having that satisfying texture.
• Add more veggies: This casserole is versatile when it comes to veggies. You can add sautéed bell peppers, zucchini, or even spinach for added nutrients and color.
• For extra creaminess: Add a block of softened cream cheese to the chicken mixture for a richer, creamier texture. This will make the casserole even more indulgent!

• Spanish rice: A simple serving of Spanish rice pairs beautifully with this casserole. The rice is mild and fluffy, making it a great accompaniment to the bold flavors of the casserole.

How to Store and Reheat Leftovers

• Reheat: To reheat, you can use the microwave for individual portions or bake in the oven at 350°F (175°C) for 10-15 minutes until heated through. Make sure to cover the casserole to keep it moist.

Make-Ahead and Freezer Tips

• Make-Ahead: This casserole can be assembled up to 24 hours in advance. Just cover it with foil and refrigerate until you’re ready to bake. This is a great option for busy nights or meal prepping.
• Freezer-Friendly: You can freeze the casserole before baking. Wrap it tightly in plastic wrap and foil and freeze for up to 3 months. Thaw it in the fridge overnight before baking as directed.

Common Mistakes to Avoid
