Cream of Mushroom Chicken Casserole – The EASY Way!

It doesn’t get much better than tender chicken breast smothered in a creamy mushroom sauce!

Being a mushroom lover, I have lots of recipes I have shared here like my Baked Chicken Marsala, Baked Cheesy Mushroom Chicken, Beef and Mushroom Casserole. We also have a from scratch Chicken with Mushroom Cream Sauce recipe we LOVE, but when I am busy or don’t want to make a mess, this is my go-to short cut recipe that is every bit as delicious and only uses 6 ingredients and one casserole dish.

It literally doesn’t get any easier than this, and the chicken is so good, people may think it took you all day!

What I love about this recipe:

Semi-homemade– We use Campbell’s cream of mushroom soup and Italian dressing mix to pack the recipe full of flavor, while saving time!
Oh the flavor! Have I mentioned how rich, creamy, and delicious this is?!
So fast- It just tastes like it took all day… really all you need is 5 minutes to get it to the oven and 20-30 minutes of bake time!
Bakes hands off- It really only takes 5-10 minutes of your attention to get this recipe going. Then it bakes with no babysitting needed so you can do what you need to do on a busy night.
Comfort food at its finest– Creamy, savory, and rich, this chicken breast dinner checks every box for a true comfort food lover!
Scales easily! You can easily double or triple the recipe if you need to feed a crowd.

Ingredients + Substitutions

Ingredients for making cream of mushroom chicken casserole with chicken breast, Campbell's cream of mushroom soup, sour cream, and seasonings.

Chicken breast– You will want to use about 3-4 chicken breasts. I like to either pound them or split them to help them to cook more quickly and evenly (more on that in tips!) You can also substitute other boneless, skinless cuts like chicken thighs, or chicken tenderloins in this recipe. It may impact the cooking time through.
Campbell’s condensed cream of mushroom soup– This is the good stuff that brings all the flavor. I use the original version to make this recipe, however, you can use light, low fat, low sodium, or a different brand if preferred. You can also use homemade cream of mushroom soup. There can be variations in flavor if doing this, but you should get a generally good result.
NOTE: You will use this soup condensed. You do not need to add water or anything other than what is on the ingredient list here before mixing into the recipe.
Sour cream- I use regular sour cream, but you can also substitute low fat sour cream or greek yogurt in this recipe with good results.
Italian dressing mix– Both pre-packed Italian dressing mix (I use Good Seasons) or homemade Italian Dressing mix can be used here to load up on flavor.
Note: This is not Italian seasoning, it is Italian Dressing Mix!
Milk– You can use whatever you have on hand!
Parmesan cheese– I prefer shredded in this recipe (over grated.) You can substitute or add mozzarella in addition to parmesan if you like a cheesier topping!

Freshly chopped parsley– Optional for garnish! I don’t usually add this on a busy weeknight, but it does really dress it up with some color to make it pretty if you are serving to guests!

Recipe Tips

Use thin chicken breast- Using chicken breasts that are thin, or pounded or cut to be thin, will help this dish cook faster, bake more evenly, and remain more tender and juicy. I almost always cut my chicken horizontally so that it is half the thickness with any of my baked chicken dishes. It just comes out better! I often end up with 6-8 pieces of chicken instead of 3-4 since I cut them which makes serving a family easier as well.
Use a big dish– You will want to use a dish large enough for the chicken to lay the chicken flat. If the chicken is not flat it takes longer to cook and you can end up with spots that aren’t completely done, or spots that are over cooked.
Don’t over cook- The enemy of delicious, tender, juicy chicken is over-cooking so make sure to cook just until the middle of the thickest part of the chicken reaches 165˚F. If you don’t have a meat thermometer I highly recommend getting one. They are inexpensive and take the guess work out of cooking so you seem like a hero with perfectly cooked meat every time!

Recipe Short Cuts

If you need to make this recipe, but are extra short on time, here are a few ideas that can help make this recipe even faster! I have 3 suggestions that can help depending on the amount of time you have.

Pre-mix the cream of mushroom soup mixture– Mix all of the ingredients for the topping together up to 2 days in advance. Refrigerate until you are ready to cook. Lay the chicken in the dish and continue with the recipe as directed.
Prepare in advance– You can make this dish earlier in the day, or up to a day in advance, and place it in the refrigerator ready to cook. Once dinner rolls around, preheat and bake the dish as directed. It may take up to 10 minutes longer to cook coming straight from the refrigerator.
Prepare as a freezer meal– You can make it up to 6 months in advance as a freezer meal. See full directions below.

Recipe Variations

If you love this recipe as much as we do and want some quick ways to change it up for variety, these little tips will do the trick!

Cream of Mushroom Chicken with Rice– The original recipe does not include rice, but can be served over a bed of rice. If you prefer to cook it all together, you can add 2 cups of quick cooking rice and 2 cups of water to the mushroom soup mixture. Add this to a large baking dish, then lay the chicken in and push down until submerged in the rice mixture. Bake for 40-50 minutes.
Cheesy Cream of Mushroom Chicken– Layer the top with a combination of shredded mozzarella and parmesan cheese, or an Italian cheese blend.
Cream of Mushroom Chicken with Crunchy Topping– If you love a little crunch then prepare this recipe as directed. Bake for 25 minutes, then add a topping of seasoned bread crumbs mixed with a little melted butter and return the oven for the remainder of the cook time.
