How to Make Fiesta Chicken Casserole Recipe
Step 1: Preheat and Cook Pasta
Begin by heating your oven to 350°F and preparing a 9×13 baking dish with cooking spray so your casserole won’t stick. Cook the rotini pasta in salted boiling water until it’s al dente, meaning just tender but still with a slight bite. This texture helps it hold up well in the casserole without turning mushy.
Step 2: Combine Sauce Ingredients
While your pasta is cooking, whisk together the sour cream, salsa, mild taco seasoning, cumin, garlic powder, and onion powder in a large mixing bowl. This creamy, zesty sauce is what turns regular ingredients into that irresistible fiesta sensation.
Step 3: Add Pasta and Mix-Ins
Drain the cooked pasta (don’t rinse it, so the sauce sticks better) and add it directly into the sauce bowl. Then fold in the drained corn, rinsed black beans, shredded chicken, and one cup of shredded cheese. Stir everything gently to combine all those bright, hearty flavors evenly.
Step 4: Assemble and Bake
Pour the entire mixture into your prepared baking dish, smoothing it out evenly. Sprinkle the remaining cheese on top to create that classic golden crust. Cover the dish loosely with foil and bake for 20 minutes. After that, remove the foil and bake for an additional 5 minutes so the cheese bubbles and browns beautifully.
Step 5: Serve and Celebrate
Once out of the oven, let the casserole sit for a few minutes—it makes it easier to slice and enhances the flavors. This dish is ready to be enjoyed straight from the casserole dish to your plate, inviting everyone to dig into a fiesta of flavors.

Make Ahead and Storage
Storing Leftovers
This Fiesta Chicken Casserole Recipe keeps beautifully in an airtight container in the refrigerator for up to 3 days. It tastes even better the next day as the flavors meld together, making it a great option for meal prep.
Freezing
If you want to enjoy this vibrant casserole later, freeze it either before baking or after cooling completely. Wrap it tightly in foil and place it in a freezer-safe container for up to 3 months. Just thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in the oven at 350°F until warmed through to preserve that cheesy, melty top. Alternatively, microwave single portions on medium power, stirring halfway to ensure even heating.
FAQs
Can I use a different type of pasta?
Absolutely! While rotini is ideal for holding the sauce, you can substitute with penne, elbow macaroni, or any short pasta you have on hand without compromising taste.
Is it possible to make this casserole vegetarian?
Yes, simply skip the chicken and add extra beans or diced vegetables like bell peppers or zucchini for a vegetarian-friendly version that still bursts with fiesta flavor.
Can I make this recipe spicier?
Definitely! Use a medium or hot taco seasoning instead of mild, add chopped jalapeños, or increase the amount of salsa to bring up the heat level to your liking.
What type of cheese works best?
Colby Jack is perfect for meltability and flavor balance, but cheddar, Monterey Jack, or a Mexican cheese blend all work wonderfully for this recipe.
Can I prepare this recipe ahead of time?
Yes, you can assemble the casserole and keep it covered in the fridge for a few hours before baking. Just add a few extra minutes to the baking time if baking cold from the fridge.
