Serve this cheesy Fiesta Chicken Casserole with a green salad, avocado, or tortilla chips for an easy meal everyone will enjoy.

Tips for the BEST Pasta Casserole

• Use sturdy pasta shapes – Rotini, fusilli, and penne hold the sauce well and maintain their texture after baking.
• Cook the pasta al dente – Slightly undercooked pasta prevents the casserole from becoming overly soft.
• Taste before baking – Salsa and taco seasoning can vary in saltiness and spice level, so adjust seasoning before the casserole goes into the oven.
• Let the casserole rest – Allow it to sit for 5-10 minutes before serving so the sauce can thicken slightly.

Frequently Asked Questions

How to Store Leftover Fiesta Chicken Bake

Store leftover Fiesta Chicken Casserole in an airtight container in the refrigerator for up to 4 days.

Reheat individual portions in the microwave or warm larger portions in a 350°F oven until heated through.

About the Ingredients for Fiesta Chicken Casserole

• Rotini pasta – Rotini works well because the spirals hold onto the creamy sauce, but penne or fusilli also work well.
• Sour cream – Full-fat sour cream gives the richest flavour and texture, though light sour cream can also be used.
• Salsa – Thick salsa works best to avoid excess liquid in the casserole.
• Black beans and corn – These pantry staples add texture, flavour, and heartiness.
• Cooked chicken – Rotisserie chicken, leftover baked chicken, or poached chicken all work well. The chicken should be fully cooked before adding it to the casserole.
• Cheese – Freshly grated cheddar and Monterey Jack melt more smoothly than pre-shredded cheese.
• Toppings – Avocado, tomatoes, cilantro, jalapeños, green onions, and sour cream all pair well with this casserole.
