How to Make Fiesta Chicken Pasta Casserole Bake Recipe
Step 1: Preheat and Prep the Baking Dish
Set your oven to 375°F (190°C) so it’s piping hot and ready to go. Lightly grease a 9×13-inch baking dish with cooking spray or a touch of olive oil—this makes serving later a breeze and prevents any sticky situations.
Step 2: Cook the Pasta
Bring a big pot of salted water to a boil and cook the penne pasta until just al dente, around 10 minutes. You want it to have a little bite, since it’ll continue cooking in the oven. Drain well and set aside.
Step 3: Prepare the Filling
In a large skillet, heat the olive oil over medium heat. Toss in the shredded chicken, black beans, thawed corn, diced tomatoes with chilies, salsa, and the packet of taco seasoning. Stir everything together and let it cook for a few minutes, just until everything is warmed and mingling. Take the skillet off the heat and stir in the sour cream—it makes the filling deliciously creamy!
Step 4: Combine Pasta and Sauce
Add your drained, cooked pasta to the skillet (or a large bowl if your skillet is packed). Stir to coat every piece of pasta with that irresistible creamy, zesty filling. Don’t worry if the pan looks overflowing; this is a casserole that’s meant to be generous!
Step 5: Assemble and Bake
Spoon the pasta mixture into your prepared baking dish. Sprinkle the Mexican blend cheese all over the top, then finish with the shredded cheddar for bonus gooeyness. Bake uncovered for 20–25 minutes, or until the cheese is melted and golden, with saucy bubbles peeking through the edges.
Step 6: Garnish and Serve
Once out of the oven, let the casserole rest for 5 minutes. Sprinkle on the sliced green onions, plus chopped cilantro and jalapeños if you love a little spice and fresh flavor. Serve hot and get ready for rounds of applause!
How to Serve Fiesta Chicken Pasta Casserole Bake Recipe

Garnishes
Topping things off makes all the difference here! Try a generous sprinkle of fresh green onions, a handful of chopped cilantro for color and zing, and sliced jalapeños if you want to amp up the heat. You can even dollop extra sour cream or drizzle hot sauce on top—bring out your inner artist!
Side Dishes
This casserole is a star on its own, but I love serving it alongside a fresh green salad, tangy coleslaw, or a platter of tortilla chips with guacamole. A side of pickled red onions or sliced avocado also adds a cool, creamy contrast to the warm, spicy flavors of the Fiesta Chicken Pasta Casserole Bake Recipe.
Creative Ways to Present
For a fun twist, portion the bake into individual ramekins and garnish each one differently. Hosting a crowd? Serve it family style straight from the bubbling casserole—you could even let everyone build their own plate with toppings like diced tomatoes, shredded lettuce, or crumbled queso fresco. Leftovers also make fantastic “pasta tacos” stuffed into warm tortillas for next-day lunches!
Make Ahead and Storage
Storing Leftovers
Leftovers will keep beautifully stored in an airtight container in the refrigerator for up to 4 days. The flavors only get better as they mingle overnight, making late-night snacking extra tempting!
Freezing
This Fiesta Chicken Pasta Casserole Bake Recipe freezes like a dream. Simply let the bake cool completely, then transfer portions or the whole casserole to a freezer-safe dish wrapped tightly with foil or plastic wrap. It will keep well for up to 3 months—perfect for future busy nights.
Reheating
To reheat leftovers, pop a portion in the microwave until piping hot, or cover the entire casserole with foil and warm in a 350°F oven until bubbly. If it looks a little dry, add a splash of milk or chicken broth before reheating to restore that irresistible creaminess.
FAQs
Can I use a different type of pasta?
Absolutely! While penne is a tried-and-true favorite for this casserole, other short shapes like rotini, fusilli, or even elbow macaroni will work wonderfully. Just make sure to cook pasta al dente for the perfect texture.
Is there a vegetarian way to make the Fiesta Chicken Pasta Casserole Bake Recipe?
Certainly! Swap out the chicken for extra black beans, a can of pinto beans, or even some sautéed mushrooms for a hearty, vegetarian-friendly version that still captures all the fiesta flavors.
What’s the best way to make this casserole spicier?
If you like a fiery kick, add diced jalapeños to the filling, choose a hot salsa, or sprinkle in cayenne pepper. A drizzle of your favorite hot sauce just before serving also takes things up a notch!
Can I assemble the casserole ahead of time?
Yes, you can put together the entire bake up to a day in advance—just cover it and refrigerate until you’re ready to bake. This is a lifesaver for busy nights or when you’re entertaining!
Will this recipe feed a crowd?
Definitely! The Fiesta Chicken Pasta Casserole Bake Recipe is perfect for sharing. It generously serves six, but can be easily doubled (or even tripled) for potlucks, family gatherings, or any time you want to make people happy.
