Spice up your dinner routine with this easy and fuss free Mexican chicken casserole. Sautéed chicken breasts are baked with a simple but delicious sauce made with sour cream, green chili and tons of Mexican cheese. This casserole is cheesy, creamy and satisfying. True comfort Mexican food.

The ingredient list is ridiculously short but do not let it fool you. The casserole is plentiful tasty and abundant in flavor. Cheese covers the chicken in a warm blanket of melty goodness, sealing in all the juices. The chicken is tender and moist.

The recipe is very easy on the brain and with a few helpful tips it comes out amazing every single time. The most important thing is to not overcook the chicken. Chicken is sautéed first on the pan so make sure not to over bake the casserole because the chicken will get dry and tough. I also like to arrange chicken pieces in a single layer and not to overcrowd the dish for a better sauce distribution.

Green chilis really amp up the Mexican flavors of the sauce. Do not drain them and use both the liquid and chilies for a better sauce consistency and flavor. The sauce is creamy and cheesy and a perfect complement to chicken.

Serve this quick and easy dish with chopped up avocado, tomatoes and fresh cilantro over rice for a complete Mexican fiesta. The dish is adult and kid friendly because green chilis are not spicy and are suitable for the little ones. Follow the instructions below to make this delicious casserole.
