I love a quick and easy dinner recipe I can get on the table with just a couple minutes of work, and that I will get no complaints from my family about. Usually pasta or anything with Tex-Mex/Mexican flavors does the trick! I am pretty sure my family would eat Sour Cream Enchiladas twice a week, every week and be happy. Especially if they can get Homemade Guacamole on the side!

This combines everything they love, and the ease and quickness I love into one delicious dinner, that I get nothing but rave reviews about.

Why You’ll Love Fiesta Chicken Casserole

  • Easy – You have to cook the pasta for this, but the oven does the rest. You just mix everything together and bake. Even those who don’t think they can cook, can master this one!
  • Versatile – I used rotisserie chicken for this to make it super easy, but you can use leftover chicken, ground beef or just about any protein you like. Don’t like corn, skip it. Want extra beans, go for it!
  • Comforting – pasta is just comfort food for so many, and this is no exception. You can use protein pasta, gluten free pasta, traditional pasta, egg noodles, or whatever you have and enjoy.

What You’ll Need

Be sure to scroll down to the recipe card to get the measurements and full instructions!

  • Cooked and Shredded Chicken
  • Corn
  • Black Beans
  • Salsa – use whatever your favorite is for flavor and spice level
  • Sour Cream
  • Pasta
  • Taco Seasoning
  • Cheese – I use a Mexican blend cheese, but you can use cheddar or whatever you like

If you want to cut down on the sodium and processed ingredients, you can make your own Homemade Taco Seasoning. Great to have on hand for taco night or whenever you want to add it to any recipe.

How To Make Fiesta Chicken Casserole

  • Start by bringing a large pot of water to boil, and cook the pasta for 2 minutes short of package directions.
  • In a large bowl mix together sour cream, salsa and taco seasoning until well blended. 
  • Stir in the shredded chicken, black beans, corn, and 1 cup of cheese. Mix until well combined.
  • Once the pasta is cooked add it to the mixture and then pour into a large casserole dish. Top with the rest of the cheese and bake.

Recipe Tips & Substitutions

  • Rotisserie Chicken. I always pick up a rotisserie chicken when I am at Costco. I break down the chicken and freeze in bags of 2-3 cup portions, so I can take it out for recipes like this, Chicken Pot Pie Noodles or add to soups.
  • Can I make it spicy? By default, this is not spicy. Even if you use a spicy salsa, mixing it with sour cream and pasta will really cut down on any heat. But you can make it spicy! Add a diced jalapeno or cayenne pepper to the sauce to get your desired heat level.
  • Don’t like black beans? You really can use any beans you like here. I suggest pinto beans if you want a different option, but really kidney beans or anything you like will work great.
  • Under cook the pasta. Make sure to under cook the pasta by 2 minutes. This will mean that after baking, your pasta is not mushy. No on likes mushy pasta!

Storing Fiesta Chicken Casserole

This is great leftover, just store in the fridge for 3-4 days. You can reheat in the oven until warmed through or in the microwave for a quick lunch.

Freezing – you can definitely freeze this casserole. It will last for up to 3 months, you can let it thaw in the fridge overnight before warming in the oven to serve. The texture will be slightly different after it thaws. If you do plan to freeze, I highly recommend using full fat sour cream and cheese, so you have less water and moisture to deal with.

Topping Ideas

This is where you can get creative! This chicken casserole is loaded with flavor, but at the same time everything is baked, so there isn’t a lot of texture. So add cool and crunchy toppings to brighten it up and add more flavors.

  • Diced Tomatoes
  • Jalapeno
  • Cilantro
  • Black Olives
  • Sour Cream

Anything goes, whatever your favorite taco toppings, go ahead and add them when you are serving.
