Easy Cheesy Fiesta Chicken Casserole Tips, FAQ & printable recipe

Tips for success

For the absolute best results, shred your own cheese from a block rather than buying pre-shredded cheese.

Pre-packaged shredded cheese contains anti-caking agents that prevent it from melting smoothly, whereas freshly shredded cheese melts into a wonderfully glossy and stretchy blanket over your casserole.

If you want to add an extra layer of texture and flavor, try stirring in some diced bell peppers or red onions along with the corn and black beans. You can also adjust the heat level of the dish easily by choosing a mild, medium, or hot creamy salsa depending on your family's preference.

Variations

• Spicy Fiesta Casserole: Add chopped pickled jalapeños and use a spicy pepper jack cheese instead of the Mexican blend for an extra kick.
• Crunchy Tortilla Topping: Crush a handful of tortilla chips and scatter them over the cheese layer during the last 5 minutes of baking for a crunchy finish.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Freezer

Freeze the unbaked or baked casserole tightly wrapped for up to 3 months. Thaw in the fridge overnight before baking or reheating.

Reheat

Reheat individual portions in the microwave for 1-2 minutes, or cover the baking dish with foil and bake at 350°F (175°C) for 15-20 minutes until hot.

Allow any leftovers to cool completely at room temperature for no more than 2 hours before storing. Transfer the cooled casserole to an airtight container and store it in the refrigerator.

It will keep well for up to 3 to 4 days, making it an excellent option for quick weekday lunches or dinners.

You can easily assemble this casserole up to 24 hours in advance. Combine all the ingredients, spread them into the baking dish, and cover the dish tightly with plastic wrap or aluminum foil before placing it in the refrigerator.

When ready to eat, remove the cover and bake as directed, adding 5 to 10 minutes to the baking time.

Serving ideas

Serve this cheesy casserole hot, straight from the baking dish. It pairs beautifully with a simple green side salad dressed with a lime vinaigrette, or with a side of warm tortilla chips and fresh guacamole.

The fresh, crisp textures of the sides balance the rich, creamy, and cheesy nature of the pasta bake perfectly.

For a festive presentation, you can garnish individual plates with sliced jalapeños, chopped fresh cilantro, or a dollop of sour cream. A squeeze of fresh lime juice right before eating adds a bright, acidic pop that cuts through the richness of the cheese and elevates the entire dish.

Easy Cheesy Fiesta Chicken Casserole

Prep 15 minCook 20 minRest 5 minTotal 40 minServes 6

Ingredients

• 8 oz rotini pasta, cooked and drained
• 2 cups shredded cooked chicken
• 1 can (15 oz) black beans, drained and rinsed
• 1 cup whole kernel corn, drained
• 1 1/2 cups creamy salsa
• 2 cups shredded Mexican blend cheese, divided

Instructions

1. In a large mixing bowl, combine the cooked rotini pasta, shredded cooked chicken, drained black beans, and drained corn. Stir the ingredients gently with a large spoon to distribute them evenly throughout the bowl.
2. Pour the creamy salsa over the pasta and chicken mixture. Stir thoroughly until the salsa completely coats all the ingredients, ensuring there are no dry pockets of pasta left.
3. Spread the creamy pasta mixture evenly into a greased 9x13-inch baking dish. Use the back of your spoon to smooth the top into a flat, uniform layer.
4. Scatter the shredded Mexican blend cheese evenly over the top of the pasta mixture, covering it completely from edge to edge.
5. Bake the casserole in the preheated oven at 375°F (190°C) for 20 minutes. The cheese should be completely melted and bubbling at the edges, and the poultry must reach a safe internal temperature of 165°F (74°C).
