Ingredients Needed for your Fajita Casserole

  • Cooked Chicken-This is a great place to use leftover chicken or even rotisserie.
  • Olive Oil-Used to cook down the onion and peppers for an authentic flavor.
  • Red Bell Pepper-Added for not only the beautiful color but also the mild pepper taste.
  • Green Bell Pepper-A traditional ingredient that is cut into strips.
  • Yellow Onion-I prefer a sweet onion but any kind of onion you have on hand or prefer will work wonderfully.
  • Fajita Seasoning-A packet of fajita seasoning is the perfect amount of spice and makes the dish super easy.
  • Cream Cheese-Added to give the dish a creamy texture.
  • Shredded Cheese-A decadent fajita isn’t complete without shredded cheese, so pick your favorite.
  • Cooked Rice-This is an optional ingredient.  If you want to make the casserole a complete meal then add it but if you want it to be a little lighter it can be left out.

How to make Easy Fajita Casserole with Chicken

  1. Add the sliced onion to a large skillet with olive oil over medium high heat.  Cook for a minute or two or until the onions are translucent.
  2. Add the sliced red and green peppers to the onions and continue to cook over medium high heat for a few minutes or until slightly softened.
  3. In a small bowl combine the softened cream cheese and fajita seasoning until they are combined.  Add it, along with the shredded {or sliced} chicken and stir until combined.
  4. Then add the cooked rice and shredded cheese and stir until everything is evenly distributed.
  5. Pour the mixture into a prepared 9×13 baking pan.  Top with the remaining cheese.
  6. Bake in a 350 degree oven covered in foil for 20 minutes.  Remove and serve.

4 Tips for the BEST Chicken Fajitas

  • Don’t use uncooked chicken.  The casserole doesn’t get baked for long, so it is important that everything is baked well before adding it to the casserole.
  • Add more meat if you prefer.  If you want the casserole to be more meat forward, then by all means…add more.
  • Cut the meat into larger pieces for a chunkier recipe.  I like to shred the chicken into small pieces but you can leave it in larger pieces for a heartier texture.
  • Don’t skip cooking the peppers and onions in a skillet.  This helps to give the casserole a good authentic flavor.

How to Serve Chicken Fajita Casserole

The first way that you can serve this Chicken Fajita Casserole is in a bowl with toppings.  It truly is a meal in itself {especially with the addition of rice}.  Some sour cream, cilantro, salsa and avocado slices are all wonderful on top.

You can also serve this Fajita Casserole with tortillas, just like you would traditional fajitas.  Layout your favorite toppings and let everyone build their fajitas to their liking.

Recipe Substitution Ideas

  • Use chicken thighs instead of chicken breasts or rotisserie chicken.  Chicken thighs tend to have a bit more flavor and stay moist longer.
  • Add sliced mushrooms to the vegetable mixture for a nice added taste and texture.
  • Use shredded pepper jack cheese for a great spicy flavor.
  • Spice the casserole up by adding a can of diced green chilies to the mixture before baking.
  • Use cooked pasta instead of rice.

Frequently Asked Questions:

Is fajita and taco seasoning the same?

They are much the same but also different.  The truth is that they are not different enough to be worried about not substituting one for the other.

You could definitely use taco seasoning if that is all you have on hand but I would add some additional cumin and a bit of lime juice to get the fajita flavor.

How do I store Chicken Fajita Casserole?

The best way to store Chicken Fajita Casserole is in the refrigerator.  Just be sure that it is covered well.  It will keep nicely in there for up to 3 days.

Can I freeze this Fajita Casserole recipe?

Yes, you can freeze this Fajita Casserole recipe for up to 3 months.  It will need to be well covered to get the best results.  Defrost it in the refrigerator overnight.

What is the best way to reheat Chicken Fajita Casserole with rice?

There are a couple of ways to reheat Chicken Fajita Casserole.  First of all, if you are only needing to reheat a serving {or two}, I would reheat it in the microwave.  Cover it with a damp paper towel {this will keep the casserole moist} and heat for a minute.  If that isn’t enough time, add 25 second increments until warm enough for your liking.

If you need to reheat the entire casserole, pour a couple of tablespoons of chicken stock into the bottom of the dish {this will help keep the casserole from drying out}.  Cover with foil and put in a 350 degree preheated oven for 20 minutes or until heated through.
