Cheesy Chicken Casserole
This savory and hearty dish is going to be a staple in your rotation of dinner recipes. It starts with seasoned and pan-seared chicken breasts and ends with a cheese sauce and more cheese on top! All the flavorful parts of the recipe are added and baked in one dish, ready to dish up to satisfy even the hungriest of eaters.
Cheesy Chicken Casserole Ingredients
Chicken Breasts: Boneless, skinless chicken breasts work best in this recipe. I used large chicken breasts, so the baking time may have to be adjusted if you are using smaller pieces of chicken. The chicken is fully cooked when it reaches an internal temperature of 165°F.
Cheese Sauce: The cheese sauce is made with sauteed onions, and there is a lot of it! So, be sure to add some to your chicken breast and use some to dunk some french fries.
Preparing the Chicken
This chicken ended up being so tender and juicy. To get it prepared, first, season the chicken breasts with the paprika, salt, pepper, and garlic powder mix. Rub the mixture into both sides of each chicken breast. Next, dredge each chicken breast in some flour, coating all sides. Set the chicken aside.
To pan-sear the chicken, melt 4 tablespoons of butter in a large skillet over medium heat. Cook each chicken breast for about 4 minutes on each side, or until browned and crispy. The chicken will probably not be cooked all the way through at this point. However, they will be baked to finish cooking them. Place the seared chicken into a 9×13-inch baking dish that has been sprayed with nonstick spray.
How to Make the Cheese Sauce
Do not clean out the skillet just yet (except for any burnt bits). To the same skillet you seared the chicken, add the remaining 2 tablespoons of butter and diced onion. Saute the onion for 5-8 minutes, or until the onion is translucent. Then, add the cream of chicken, heavy cream, and a cup of shredded cheese. Whisk the ingredients together to form a sauce.
How to Make Cheesy Chicken Casserole
Once the chicken has been prepared and the sauce mixed together, it’s time to get this hotdish baked and on the table! Pour the cheese sauce over the tops of the chicken breasts that are in the baking dish. Bake at 350°F for about 40 minutes. (Again, baking times can vary depending on the size of chicken you use.)
After 40 minutes, sprinkle the remaining cup of shredded cheese over the top of the chicken. Bake for another 20 minutes, or until the cheese is hot and bubbly. Chicken is fully cooked when each chicken breast has an internal temperature of 165°F.
When serving, don’t forget to use all that cheese sauce that may have settled in the dish. Spoon some sauce over your chicken breast. Or, use it as a dipping sauce for some Roasted Potato Wedges.
