I love one pot cooking. The Instant Pot helps make that possible and I love it! Fiesta Chicken Casserole is infused with all these yummy flavors and is a perfect combination.

But that’s not all, making the pasta in the Instant Pot or Pressure Cooker infuses even more flavor right into the pasta. Definitely a tip you don’t want to miss.

Make this recipe with Chicken Tenders or Chicken Breasts sliced, either way is perfect and we love to use a Radiatore Pasta too! But any pasta will work just fine! 😉

Delicious Easy Ingredients:

  • Chicken ~ I use Chicken Tenders or Chicken Breasts sliced
  • Pasta ~ You can use what you prefer but don’t these Radiatore Pasta look so fun?
  • Salsa ~ Mild, Medium or Hot you decide!
  • Seasonings – Cumin, Chili Powder, Garlic Powder or a good Taco Season packet works too.
  • Corn – Sweet Canned Cord works great for this recipe.
  • Black Beans ~ Soak your own or open the can they add great texture and flavor
  • Cheese ~ I prefer a good Mexican Blend Cheese but Colby Jack works well too.
  • 1/2 Cup Sour Cream
  • Toppings ~ Tomatoes, Green Onions, Limes, Cilantro, and Avocado. Just load it up

How to Make Fiesta Chicken

I like to make Fiesta Chicken in the Instant Pot because it truly is a one pot meal made this way. The flavors all come together so nicely.

However this recipe can also be made on the stove as well. Which ever you prefer. See the instructions below in the recipe card.

What to serve with Fiesta Chicken Casserole?

Casseroles typically have multiple food groups covered and this casserole is no exception. However, a good green salad or fresh fruit would be delicious! Why not try some Watermelon Salsa with dinner?

What Kind of Chicken do you Use?

I use either Chicken Breasts sliced thin or Chicken Tenders. You can use any type of chicken or even leftover cooked chicken. Rotisserie Chicken is also wonderful!

Can I make Substitutions?

I am all about making substitutions to cut fat, or sodium or for other health reasons or allergies. So yes! Go for it! Of course I have not tested all combinations of substitutions, but try using a plain Greek Yogurt in place of the Sour Cream. It’s delicious!

Can I use Taco Seasonings in place of other spices?

I’ve always said, use what you have. So YES! You can use Taco Seasonings in place of these other spices, use as much or little as you desire. Everyone likes their own level of flavors anyways. 😉

Quick Tips

Don’t have Chicken Tenders? No problem! If using Chicken Breasts, make sure to slice them the long ways. To cook the pasta and chicken all at the same time you will want your chicken to be in Chicken Tender Sizes.
