Chicken & Zucchini Casserole Recipe

*Specific measurements and complete recipe instructions are located in a printable recipe card at the bottom of this article. However, be sure to continue to read the tips and tricks to making this recipe below.

INGREDIENTS

  • 6 ounces boxed chicken stuffing mix
  • ½ cup butter melted
  • 4-5 cups diced zucchini (about 3 medium size whole zucchini)
  • 4 cups cooked and diced chicken*
  • 10 ½ ounces canned cream of chicken soup, low-sodium
  • ½ yellow onion, diced
  • ½ cup sour cream

*If you prefer to use fresh chicken, use 1 1/2 large chicken breasts and cut the meat in small cubes. Then increase the cook time to 1 hour.

Be sure to check the chicken to make sure that the internal temperature reaches 165°F for safe consumption.

INSTRUCTIONS

Start by preheating the oven to 350°F (177°C). Then spray a 9 x 13 inch baking dish or a 3 quart oval casserole dish with nonstick spray and set aside.

In a large bowl, combine the chicken stuffing mix and melted butter. Mix until all of the stuffing mix is moistened.

Be sure to stir the stuffing and melted butter together until all of the bread pieces are moist.

Remove 1/2 cup of the moist stuffing mixture and set it aside. This will be used for the crunchy topping on top of the chicken & zucchini casserole.

Cut the zucchini in 1/2 – 1 inch, bite size pieces. You don’t have to peel the zucchini unless you prefer to do so. Then dice the onion into small pieces.

The Best Way To Dice An Onion

The easiest and best way to dice an onion is to cut an onion in half from top to bottom. Remove the skin but leave the bottom root section intact.

Place the cut side of the onion face down on a cutting board. Then take a sharp knife and make 1/4 inch slices from the top of the onion to within 1/4 inch of the bottom.

However, do not slice it all the way through the bottom of the onion. Then cut in the opposite directions, starting from the top and working toward the root.

You will then have perfectly diced onion to add to your chicken & zucchini casserole!

Mix The Ingredients Together

Add the diced zucchini, diced cooked chicken, cream of chicken soup, onion and sour cream to the bowl with the moistened stuffing. Stir to mix everything together until well incorporated.

Spread the mixture in the prepared baking dish. Then sprinkle the reserved stuffing mix on top of the mixture.

The topping will not coat the entire surface. However, it will add a little crunch throughout the casserole. Now place the baking dish in the preheated oven and bake for 40-50 minutes.

If you are using uncooked chicken, remember to bake it for about an hour. And be sure to check the chicken for doneness with an instant read digital thermometer before serving.

The casserole is done when it is heated through, bubbly up the sides and the top is golden brown. Or when the uncooked chicken reaches 165°F.

Remove from the dish from the oven and let it sit for 5 minutes before serving.
