Ingredients You’ll Need

• Pasta: The foundation of our casserole; choose penne, rotini, or any medium-sized pasta that can hold up to the sauce and mix-ins.
• Chicken: Pre-cooked, shredded chicken adds protein and substance. Use rotisserie chicken for extra convenience and flavor.
• Rotel tomatoes: These canned tomatoes with green chilies provide instant flavor and a touch of heat without extra work.
• Sour cream: Creates creaminess and provides a subtle tang that balances the spices perfectly.
• Corn: Adds sweetness and texture contrast to the dish; use fresh when in season for the best flavor.
• Black beans: Provides extra protein, fiber, and that classic southwestern flavor profile.
• Black olives: Adds a briny, earthy note that complements the other ingredients; save some for garnish.
• Green chilies: Brings mild heat and authentic Mexican flavor without overwhelming the dish.
• Cream of chicken soup: Acts as the binding agent in our casserole and creates a rich, velvety sauce base.
• Cumin and garlic salt: These spices are essential for authentic Tex-Mex flavor without requiring a full spice cabinet.
• Mexican blend cheese: Creates that irresistible melty, stretchy top layer; reserve some for extra cheesy goodness on top.
• Cilantro: Fresh cilantro brightens the whole dish with its distinctive herbal notes.

Variations

Spice It Up

Add diced jalapeños or a dash of hot sauce for those who like more heat. Alternatively, use pepper jack cheese for a spicier version.

Vegetarian Version

Skip the chicken and double up on beans, or add vegetarian crumbles. Use cream of mushroom soup instead of cream of chicken soup.

Protein Swap

Try using ground beef, turkey, or chorizo instead of chicken for a different flavor profile.

Grain-Free Option

Replace pasta with cauliflower florets for a lower-carb version that still captures all the flavors.

How to Make Fiesta Chicken Pasta Casserole

Step 1: Prepare the Basics

Preheat your oven to 350°F. Cook the pasta according to package directions until just al dente, as it will continue cooking in the oven. Remember to slightly undercook the pasta to prevent it from becoming mushy in the casserole.

Step 2: Mix the Ingredients

Set aside 1 cup of cheese, ¼ cup of black olives, and the cilantro for topping. In a large mixing bowl, combine all remaining ingredients – shredded chicken, Rotel, sour cream, corn, black beans, remaining black olives, green chilies, cream of chicken soup, cumin, and garlic salt. Stir until everything is evenly distributed.

Step 3: Combine with Pasta

Add the cooked and drained pasta to your mixture. Gently fold everything together until the pasta is well coated with the sauce and the ingredients are evenly distributed throughout.

Step 4: Assemble and Bake

Transfer the mixture to a 9×13-inch baking dish, spreading it out evenly. Top with the reserved cup of Mexican blend cheese. Cover the dish with aluminum foil and bake for 20 minutes, which allows all the flavors to meld together while keeping the inside moist.

Step 5: Finish and Serve

Remove the foil and bake for an additional 5 minutes until the cheese is bubbly and starting to get golden spots. Take the casserole out of the oven and let it rest for a few minutes. Sprinkle with the reserved black olives and fresh cilantro before serving.

Pro Tips for Making the Recipe

• Pasta Choice Matters: Choose a pasta shape with ridges or curves that can trap the sauce and small ingredients.
• Al Dente is Key: Cook your pasta 1-2 minutes less than package directions as it will continue to cook in the oven.
• Layer Your Cheese: Mix some cheese into the casserole itself, not just on top, for pockets of melty goodness throughout.
• Rest Before Serving: Let the casserole sit for 5 minutes after baking to allow the sauce to set up slightly, making it easier to serve.
• Make Your Own Rotel: If you can’t find Rotel, combine diced tomatoes with a small can of diced green chilies as a substitute.

How to Serve

Main Dish Companions

Serve with a simple green salad dressed with lime vinaigrette or a side of Mexican street corn for a complete meal.

Garnish Options

Besides the cilantro and black olives, offer a topping bar with diced avocado, fresh salsa, extra sour cream, sliced jalapeños, and lime wedges so everyone can customize their portion.

Bread Sides

Warm tortillas or crusty garlic bread make excellent companions to soak up the delicious sauce.

Make Ahead and Storage

Storing Leftovers

Store any leftover casserole in an airtight container in the refrigerator for up to 4 days. The flavors actually improve overnight as they have time to blend together.

Freezing

This casserole freezes beautifully. Prepare through assembly, but don’t bake. Cover tightly with aluminum foil and freeze for up to 3 months. Alternatively, freeze individual portions of fully cooked casserole for quick lunches.

Reheating

For refrigerated leftovers, reheat in the microwave for 2-3 minutes or in a 350°F oven for about 15-20 minutes until heated through. For frozen unbaked casserole, thaw overnight in the refrigerator before baking as directed, adding 10-15 minutes to the covered baking time.

FAQs

Can I use a different type of pasta in this recipe?
Absolutely! Any medium-sized pasta works well in this recipe. Rotini, shells, bowties, or penne are all excellent choices. The key is to use pasta that can hold the sauce and mix-ins well. Just remember to cook it al dente since it will continue cooking in the oven.

How can I make this casserole healthier?
For a healthier version, use whole grain pasta for extra fiber, Greek yogurt instead of sour cream, reduced-fat cheese, and add extra vegetables like bell peppers or zucchini. You can also use low-sodium beans and soup to reduce the salt content while maintaining flavor.

My family doesn’t like spicy food. How can I adjust this recipe?
This casserole is already fairly mild, but you can make it even more family-friendly by using mild Rotel tomatoes or substituting them with regular diced tomatoes. You can also omit the green chilies entirely or use just half the can for a subtle flavor without the heat.

Can I prepare this the night before and bake it the next day?
Yes! This makes an excellent make-ahead meal. Assemble the entire casserole, cover tightly with plastic wrap or foil, and refrigerate overnight. When ready to bake, remove from the refrigerator about 30 minutes before to take the chill off, then bake as directed, adding about 5-10 minutes to the covered baking time.
