How to Make Chicken Fajitas Casserole

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.

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.

Recipe Tips

• Make Homemade Seasoning for Best Flavor: I highly recommend making my easy homemade fajita seasoning. It only adds a few minutes to this recipe, and the flavor it provides is well worth it.
• Shred 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.
• Different Protein: You can easily make these chicken fajitas into a meat-lovers casserole! 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.
