Step-by-Step Fajita Chicken Casserole Instructions
Preparing Your Fajita Chicken Casserole
This Fajita Chicken Casserole comes together in about an hour, start to finish. You’ll need a large skillet or Dutch oven for sautéing the veggies, as well as a 9×13 baking dish to assemble and bake the casserole. Once you’ve got all your ingredients prepped, it’s a straightforward process that results in an incredibly comforting and delicious dish.
1- Begin by marinating the chicken in the fajita seasoning, salt, and pepper for at least 30 minutes (or up to 24 hours) in the refrigerator.
2- Preheat your oven to 375°F. In a large skillet, sauté the bell peppers and onions in a bit of oil over medium-high heat until they’re tender and starting to caramelize, about 8-10 minutes.
3- Remove the veggies from the pan and set them aside. In the same skillet, brown the marinated chicken on both sides until it’s cooked through, about 6-8 minutes per side.
4- Slice the cooked chicken into strips or bite-sized pieces, then layer it in the bottom of a 9×13 baking dish. Top the chicken with the sautéed peppers and onions.
5- In a small bowl, mix together the sour cream and 1/2 cup of the shredded cheese. Spread this creamy cheese mixture evenly over the top of the casserole.
6- Finally, sprinkle the remaining cheese over the top and bake for 20-25 minutes, until the cheese is melted and bubbly. Let it cool for 5 minutes before serving.
Pro Tips for Success
The key to perfect Fajita Chicken Casserole is all in the prep work. Make sure to marinate the chicken for at least 30 minutes (or up to a day) to really let those flavors soak in. And don’t be afraid to get a good sear on the chicken before baking – that adds tons of flavor. Also, be careful not to overbake the casserole, as you don’t want the cheese to get dried out.
