Recipe Ingredients

The following simple ingredients create a delicious chicken fajita bake. If you are looking forward to a hearty, cheesy dish, start heading to the grocery store!

  • Baked Chicken Breasts: I recommend making my Juicy Oven Baked Chicken Breasts for the best baked chicken! Or, you can always just use that rotisserie chicken from your local grocery store.
  • Olive Oil: For sautéing the vegetables. Canola oil or vegetable oil can also be used.
  • Red & Green Bell Peppers: Sliced into thin strips, they add fresh flavor and color. Any color bell pepper will work.
  • Yellow Onion: White onion is a good substitute.
  • Cream Cheese: Provides a creamy texture and rich taste.
  • Cheddar Cheese: I love using white and yellow cheddar for this recipe, but you can definitely opt for your favorite shredded cheese.
  • Fajita Seasoning Mix: You can’t go wrong with my 5 Minute Homemade Fajita Seasoning.
  • Fresh Cilantro: Parsley works too! Use your favorite garnish.

How to Make Chicken Fajitas Casserole

This easy-to-make dish combines tender chicken, crunchy vegetables, and creamy cheese for a delightful, baked meal. Follow these simple steps to prepare tonight’s dinner!

  1. Preheat the Oven: Set your oven to 350˚F and lightly grease a 9×13 baking dish with cooking spray.
  2. Shred Chicken: Shred the baked chicken breasts and then transfer to a large mixing bowl; set aside.
  3. Heat Oil: Heat olive oil in a skillet set over medium-high heat.
  4. Cook Peppers & Onions: Add peppers and onions to the hot oil; sprinkle with salt and until softened. Remove from heat and set aside.
  5. Make Seasoning: In a large bowl, combine cream cheese, half of shredded cheese, fajitas seasoning mix, salt, and pepper. Mix until thoroughly combined.
  6. Add to Chicken: Add cream cheese mixture to the chicken and peppers; mix until everything is well combined.
  7. Assemble: Transfer chicken mixture to previously prepared baking dish and sprinkle with remaining shredded cheddar cheese.
  8. Bake: Bake for 25 to 30 minutes, or until hot and bubbly, and cheese is melted.
  9. Garnish & Serve: Remove from oven and garnish with chopped cilantro or parsley.

Recipe Tips

  • Make a homemade seasoning: I highly recommend making an easy fajita seasoning consisting of chili powder, garlic powder, ground cumin, paprika, dried Mexican oregano, salt, and pepper. It only adds a couple of minutes to this fajitas casserole, but the flavor is well worth it.
  • Shred the chicken to your liking: If you want a chunkier chicken casserole, you can cut the chicken breasts into cubes rather than shredding them. It’s completely up to you and your preferences.
  • Use a different protein: You can easily make these chicken fajitas into a meat-lovers dish! Try adding sliced sausage, ham, bacon, or any other meats you love.

Serving Suggestions

This recipe is so versatile, and these Lemon Butter Green Beans or these slow-cooked Green Beans and Tomatoes are great with it. Another classic combination for chicken fajitas is rice. I often pair this recipe with my Instant Pot Mexican Rice or this Creamy Garlic Butter Parmesan Rice. You could also make these fajitas into tacos, burritos, and quesadillas! Don’t forget my Tres Leches Cake for the perfect finish.

How to Store and Reheat Leftovers

  • You can easily store your leftovers in the refrigerator for 3 to 4 days or in the freezer for 1 to 2 months. Thaw before reheating.
  • Reheat individual servings in the microwave to your preferred temperature.

    Do you think this could be assembled and frozen for future use? Making meals for sick family but must be able to freeze anything I take

    1. Katerina says:

      Hi!
      Technically yes, you can freeze just about any casserole, however, cream cheese (and all creamy casseroles) are a bit tricky to freeze because the fats tend to separate. Because of that the texture and flavor suffer. I would suggest to freeze the other ingredients and add the cream cheese later, after the dish has thawed, and right before cooking.

    My family loved this recipe. They were missing being able to eat it as a fajita so I gave them shells and chopped lettuce. Fantastic. Thank you.

    I made this last night and it was delicious. My only complaint is that it was too salty. But that was my fault, I used store bought fajita seasoning. Next time I’m going to make the one you listed. Thanks so much for the recipe.

    My fiancé is an extremely picky eater and I’ve been trying to expand his taste buds. He’s never had a fajita before and was hesitant to try it. While it was cooking, he kept saying how delicious it smelled (I licked the bowl clean after throwing the dish in the oven). He ended up loving it so much he had a huge second helping. This is a definite winner recipe to be made many more times. It was so flavorful and made enough for the two of us to have leftovers the next day. I can’t wait to continue trying different sides with this making it in the future. Also after reading the other reviews, I can’t comment on if it was too salty by following the recipe. I have to watch my salt intake since I’m 7 months pregnant so I only used a dash of salt when baking the chicken and a dash in the pepper/onion mix and it was perfect!

      I am very glad you and your fiance enjoyed this dish! Thank you for chiming in! 🙂

    Made this tonight and it was wonderful! I was a little skeptical because I didn’t think 8 oz of cream cheese sounded like enough. I added a small amount of chicken broth from cooking the chicken (maybe 1/4 cup), and probably used more peppers and chicken than the recipe called for. I will definitely make this again!

    1. Katerina Petrovska says:

      That’s great! I’m very happy you enjoyed it! Thank YOU! 🙂

      1. Beth says:

        My husband wanted the leftovers for dinner tonight! It’s a miracle there was any left 😮

          That’s great to hear! 🙂 I’m very happy you and your family enjoyed it! Thank you for chiming in! 🙂

    I made this last night and while it is delicious, to me there was too much cream cheese. Next time I’m going to try to come up with some combination of at least 1/2 as much cream cheese, mixed with something like plain Greek yogurt or sour cream. Do you have any suggestions?

    Hello,
    Can this recipe be made the day before?
