Ingredients You’ll Need

Here’s what you’ll need to make your casserole magic happen:

• Cooked and Shredded Chicken: The star protein of this dish. Rotisserie chicken works beautifully and saves time.
• Corn Kernels: For a pop of sweetness and color that balances the spices.
• Black Beans: Add heartiness, texture, and protein. Be sure to rinse and drain them well.
• Salsa: Brings a zesty tomato base and layers of flavor. Use mild or spicy, depending on your heat preference.
• Sour Cream: Adds creaminess and tang—don’t skip it! It helps bind everything together and gives that luscious texture.
• Pasta: A neutral, comforting base. Short pasta shapes like rotini or penne work best.
• Taco Seasoning: The flavor booster. Use store-bought or homemade for full control over spice levels.
• Mexican Cheese Blend: A perfect mix of melty cheeses like cheddar and Monterey Jack for that bubbly, golden top.

Variations

Want to customize your casserole? Go for it! Here are a few tasty ideas:

• Make it Spicier: Add diced jalapeños or hot salsa for extra heat.
• Low-Carb Version: Swap pasta for cauliflower florets or use zucchini noodles.
• Add Veggies: Diced bell peppers, onions, or spinach make great additions.
• Different Protein: Ground beef, leftover turkey, or even plant-based crumbles can be used instead of chicken.
• Dairy-Free: Use dairy-free cheese and a vegan sour cream substitute to make this dish friendly for lactose-intolerant folks.

How to Make Fiesta Chicken Casserole

Step 1: Preheat and Prep

Preheat your oven to 350°F. This gives you time to prep everything else while the oven heats.

Step 2: Cook the Pasta

Bring a large pot of salted water to a boil. Cook the pasta two minutes short of the package directions. This keeps it from getting mushy in the oven. Drain and set aside.

Step 3: Make the Creamy Base

In a large mixing bowl, combine the sour cream, salsa, and taco seasoning. Stir until smooth and evenly blended.

Step 4: Add the Good Stuff

Toss in the shredded chicken, black beans, corn, and 1 cup of the cheese. Mix everything together until well coated in the creamy mixture.

Step 5: Combine with Pasta

Add the drained pasta to the bowl and fold it all together gently until the sauce hugs every piece.

Step 6: Assemble the Casserole

Pour everything into a greased casserole dish. Spread it out evenly, then top with the remaining cheese.

Step 7: Bake to Perfection

Bake for 20–25 minutes, or until the cheese is melted, golden, and bubbly. Let it cool slightly before serving.

Pro Tips for Making the Recipe

• Undercook the Pasta: It will continue cooking in the oven, so boiling it slightly less keeps it perfectly al dente.
• Use Rotisserie Chicken: It’s juicy, flavorful, and saves a ton of time.
• Customize the Spice Level: Use mild salsa for a family-friendly version or go bold with hot salsa and extra seasoning.
• Let It Rest: Give the casserole a few minutes to settle after baking. It helps everything firm up for easier serving.

How to Serve

This dish is filling on its own, but it pairs wonderfully with:

Toppings:

Sliced avocado, chopped cilantro, diced tomatoes, or a dollop of sour cream add freshness and flair.

Sides:

Try serving it with a crisp green salad, tortilla chips with guacamole, or a side of Mexican rice to stretch the meal for a crowd.

Drinks:

Pair with iced tea, a cold cerveza, or a margarita if you’re feeling festive.

Make Ahead and Storage

Storing Leftovers

Store any leftovers in an airtight container in the refrigerator for up to 4 days. The flavors get even better the next day!

Freezing

Freeze in individual portions or the whole casserole (after baking) in a freezer-safe container for up to 3 months. Just be sure to cool it completely before freezing.

Reheating

Reheat individual servings in the microwave or pop the casserole back into a 350°F oven until warmed through. Add a splash of water or extra salsa to prevent drying out.

FAQs

Can I make this casserole ahead of time?
Absolutely! You can assemble the entire casserole a day in advance, cover it, and refrigerate. When ready to bake, let it sit at room temperature while the oven preheats.

What type of salsa works best?
Use your favorite brand—chunky, smooth, mild, or spicy. If you want more heat or flavor depth, go for a fire-roasted or chipotle-style salsa.

Can I use a different type of pasta?
Definitely. Any short-cut pasta like penne, rotini, or elbow macaroni will work. Just avoid long noodles like spaghetti—they don’t hold the sauce as well.

Is there a gluten-free option?
Yes! Simply use gluten-free pasta and double-check that your taco seasoning and salsa are gluten-free.
