Ingredients and Variations

This cream of chicken casserole recipe is a fast, family favorite made with simple, budget friendly ingredients likely already in the kitchen!

Chicken – Use precut thawed chicken strips or cut boneless, skinless chicken breasts or thighs into strips or chunks.

Mushrooms – This dish is loaded with mushrooms, so timesaving canned mushrooms that are pre-sliced are perfect in this recipe. You can add 1½ pounds of fresh mushrooms as well (see recipe below).

Soup – No need to buy Campbell’s if a store brand of cream of mushroom soup is available! You can also use cream of chicken, cream of broccoli, or cream of celery soup. For a thicker sauce, use heavy cream instead of milk, if desired.

Variations – Sneak in some spinach, shredded zucchini or a frozen vegetable medley and the kids won’t even notice! Add some ham and provolone to make a quick chicken cordon bleu casserole, or add broccoli to create a broccoli chicken curry casserole.

Notes

*Replace frozen onion with one small diced onion.
To use fresh mushrooms in place of canned mushrooms:
  • Heat 1 tablespoon of oil in a large skillet over medium heat. Add 1 1/2 pounds of sliced fresh mushrooms in a single layer. Cook for 3-5 minutes without stirring until browned. Toss, and cook for an additional 3-5 minutes.

    1. Hi Deborah, we have only made this recipe as listed. But you will need to adjust the cooking times based on the type of chicken you are using.

    Thanks For Sharing this Amazing Recipe. My Family Loved It. I will be sharing this Recipe with my Friends. Hope They will like it.

    1. Hi Joanna, yes it is. But you can definitely reduce the number of mushrooms if you prefer. Or swap some out for another vegetable you enjoy!

    1. I have only tried the recipe as written but I think that would work and it will change the taste and texture a bit. Let us know if you try it Virginia!

    1. Randall – sorry about that. 350 degrees and 2 tablespoons minced garlic. Enjoy! We have updated the recipe card as well.
