How to Make Chicken Fajita Casserole
The steps are quite simple, here’s what you’ll need to make this delicious dinner:
The Ingredients
Chicken: Preferably skinless and boneless chicken breasts. You could also opt for thighs if that’s what you have on hand. Bell peppers: Grab different colored ones if you can, it makes the dish colorful and fun. Shredded cheese: Your choice here – Mexican blend, mozzarella, cheddar, or even fontina works great here. Fajita seasoning: I always make my own homemade fajita seasoning as it’s healthier, cheaper, and so easy to make! Onion: A yellow onion is perfect for this recipe.

The instructions
Once you gather the ingredients, making this chicken casserole is a breeze! I like to use a baking dish, but you can also use a baking sheet if that’s what you have.
Make-Ahead Tips
If you’re planning ahead, this casserole can be prepared in advance! Simply prepare it up to the baking step, cover it, and store it in the fridge. When you’re ready, just bake it as instructed – a real time-saver for busy days.
Tips and Variations
To cook this chicken casserole quicker, you can cube the chicken into smaller pieces and reduce the cooking time. Feel free to leave out the cheese if you want a lighter version of this. Swap out the cheese with a breadcrumb topping. Season panko breadcrumbs with garlic powder, paprika, salt, and pepper. You can add cooked pasta to the casserole (cooked to al dente). Reheat in the oven at 350°F (180°C) for 15-20 minutes, or in the microwave if that’s easier.
What to Serve With
Turn this meal into a feast by serving it with some of these delicious sides:
Garlic butter pasta or plain pasta. Plain rice or a fancier Mexican rice. For a low-carb option, cauliflower rice pairs wonderfully.
Don’t forget some fresh sides to balance the meal! Quick pico de gallo, lime crema, and fresh guacamole are easy to whip up and add a burst of freshness to your meal.
