Fiesta Chicken Casserole is a family friendly meal that is sure to become a favorite! This cheesy chicken casserole is easy to make, using canned beans, corn and tomatoes. Can be made in under an hour!

This is a great “pantry” meal. Use up all of those cans in the pantry and either rotisserie chicken or left-over chicken you might have in the fridge. This dinner can be made in under an hour and it’s also a great freezer meal.

Easy Chicken Casserole With Rotel

Our family loves this cheesy fiesta chicken casserole, especially on busy weeknights. We can usually eat it for 2 dinners during the week. It is also one of my favorite dishes to make for potlucks or to bring to new moms.

Ingredients 

Rotini Pasta – My family loves Rotini but macaroni or ziti would be great too. 

Shredded ChickenI like using Rotisserie chicken or this Air Fryer Rotisserie Chicken

Black BeansI just use canned beans for this recipe. 

CornYou can use canned or fresh corn kernels.

Diced Tomatoes with Green Chilies – I used mild Rotel for this, you could also use salsa or petite diced tomatoes.

Tips for a delicious casserole

  • Make this over the top by adding an extra dollop of sour cream, diced jalapenos and black olives. 
  • Dice or shred the chicken into small pieces so it’s easier to eat.
  • If you don’t like beans (like my mom) feel free to omit them or substitute with pinto or white beans. 
  • If you don’t have Rotel, you can use a cup of your favorite salsa.

Can you freeze

Yes! Prepare the casserole but do not bake. Cover the dish with plastic wrap and then tightly with foil. If I know I’m going to freeze, I like making them in disposable pans. 

To bake, let the casserole thaw in the refrigerator overnight. Remove plastic wrap and foil. Bake at 350 degrees for 20-30 minutes.
