How to Make Chicken Fajitas Casserole (easy and cheesy!)
Ready to dive into the deliciousness? Follow these simple, step-by-step instructions to create your Easy Chicken Fajitas Casserole:
Step 1: Preheat and Sauté
Preheat your oven to 350°F (175°C). In a large skillet, heat the olive oil over medium heat. Once the oil is shimmering, add the bite-sized chicken pieces and sauté until they’re cooked through and golden brown. Remove the chicken from the skillet and set aside.
Step 2: Sauté the Veggies
In the same skillet, toss in the sliced onions and bell peppers. Sauté until they reach your desired tenderness—this usually takes about 5-7 minutes. The colors will brighten, and the sweet aroma will fill your kitchen!
Step 3: Combine Everything
Return the cooked chicken to the skillet and sprinkle in your fajita seasoning. Stir in the sour cream and softened cream cheese, mixing everything until well combined. The mixture should be creamy and luscious!
Step 4: Cheese It Up and Bake
Sprinkle the grated cheddar cheese generously over the top of the chicken and veggie mixture. Pop the skillet into the preheated oven and bake for 10 to 15 minutes, or until the cheese is melted and bubbly—this is the moment you’ve been waiting for!
Pro Tips for Making Chicken Fajitas Casserole (easy and cheesy!)
– Prep Ahead: Chop your veggies and chicken in advance to save time on busy nights.

– Taste as You Go: Adjust the seasoning to your preference; you can always add more spice if you like it hot!
– Let it Rest: Allow the casserole to sit for a few minutes after baking—this will help it set for easier serving.
