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 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.

  1. Thank you dear Amanda! I ❤️ your recipes – but for some reason they no longer print for me. But thanks anyways! Lydia💜💥👍😄

    1. Sorry about that, Lydia! If you open them in a new browser, like google or chrome, they will print. It’s a known issue from Facebook and they don’t seem willing to fix it 🙁

    So very good! My husband is always asking for me to make it. I do add about 16oz of frozen or fresh broccoli florets around the chicken before adding the sauce… there’s enough sauce for this. I also serve it with rice. So very good!❤️❤️

  3. I have made this once and am going to make it again tonight for my husband and myself. We loved it. I make so many of your recipes and have been pleased with all of them

  4. Can you substitute thighs or have a combination of breasts and thighs. What would that do to the cooking time

      1. Search dairy free homemade cream of mushroom soup for a dairy free option. I cant do any cream soups due to allergies but the dairy free vesion is way better then canned in taste as well.

    I’ve already made this recipe TWICE since I found it. It’s a really great homecooked meal and it makes us (two people) lots of leftovers! It’s got a ton of flavor to it and is a pretty easy dish to put together. I also put broccoli florets on top of the chicken before I poured the sauce over and made sure to spread it well. It was easy to add vegetables in that way and was SUPER tasty. The recipe produces enough sauce for this. Thanks, IamHomesteader!

  6. Can I sub out the cream for half and half! I am making this later this evening, let me know soon! Thank you!

    1. You could, but I have not tested it specifically so can’t say if it will change texture/flavor at all. But, in theory it should work. 🙂
