How to Make Fiesta Chicken Casserole
Step 1: Preheat the Oven
Heat your oven to 350°F (175°C). Prepare a 9×13 baking dish by spraying it with cooking spray to prevent sticking.
Step 2: Cook the Pasta
Cook the rotini pasta according to package directions until al dente. Remember to salt the water—about 1 teaspoon should do. Once done, drain the pasta but do not rinse it.
Step 3: Mix Ingredients
In a large mixing bowl, combine sour cream, salsa, taco seasoning, cumin, garlic powder, and onion powder. Stir well until combined.
Step 4: Combine Everything
Add the drained pasta into the sour cream mixture. Stir gently to incorporate everything. Then add in corn, black beans, cooked chicken, and 1 cup of shredded cheese. Mix until evenly distributed.
Step 5: Bake the Casserole
Pour the mixture into your prepared baking dish. Sprinkle the remaining cheese on top. Cover with tin foil and bake for 20 minutes.
Step 6: Finish Baking
Remove the tin foil and bake for an additional 5 minutes until bubbly and golden on top. Garnish as desired with sour cream, diced tomatoes, chopped cilantro, or avocado slices before serving. Leftovers can be stored covered in the fridge for up to 3-4 days.

How to Perfect Fiesta Chicken Casserole
To ensure your Fiesta Chicken Casserole turns out perfectly every time, consider these handy tips.
- Use Rotini Pasta: This pasta shape holds onto the sauce and ingredients well, ensuring every bite is flavorful.
- Don’t Rinse Pasta: Rinsing removes starch that helps sauces adhere. Drain but don’t rinse for the best texture.
- Adjust Seasoning: Feel free to tweak taco seasoning based on your spice preference; add more if you like it hotter!
- Opt for Rotisserie Chicken: For convenience, using pre-cooked rotisserie chicken saves time and enhances flavor.
- Cover While Baking: Covering with foil during baking keeps moisture in and prevents over-browning.
- Let It Rest: Allowing the casserole to sit for a few minutes after baking helps it set and makes serving easier.
Best Side Dishes for Fiesta Chicken Casserole
Pair your Fiesta Chicken Casserole with these delicious side dishes for a complete meal experience.
- Mexican Rice: Fluffy rice seasoned with spices complements the casserole’s flavors beautifully.
- Refried Beans: Creamy refried beans add protein and richness, making them an excellent side choice.
- Cornbread: Sweet cornbread offers a comforting contrast to the spicy casserole.
- Grilled Vegetables: Grilled zucchini, bell peppers, and onions bring color and health benefits to your plate.
- Coleslaw: A crunchy coleslaw provides a refreshing crunch that balances out the heaviness of the casserole.
- Tortilla Chips with Salsa: Crispy chips paired with fresh salsa create a fun appetizer or snack before diving into the main dish.
Common Mistakes to Avoid
Making Fiesta Chicken Casserole can be a breeze, but there are some common mistakes to watch out for.
- Using Overcooked Pasta: Ensure your pasta is cooked al dente. Overcooked pasta can become mushy in the casserole.
- Skipping the Seasoning: Don’t forget to add all the spices! Taco seasoning and other spices enhance the flavor of your casserole.
- Not Draining Ingredients: Always drain your corn and black beans. Excess liquid can make the casserole watery.
- Using Cold Ingredients: Let your cooked chicken come to room temperature before mixing. Cold ingredients may not blend well with the hot pasta.
- Overbaking the Dish: Keep an eye on cooking times. Overbaking can lead to a dry casserole that loses its creamy texture.
