This Chicken Zucchini Casserole is a one pan wonder! It’s easy to make. Creamy and hearty without relying on canned cream of chicken soup. And it’s chock full of vegetables, which makes this casserole healthier for you and easier on your budget.

Do you have a cast iron skillet? I’ve got to tell you, the more time I spend in the kitchen, the more I appreciate my cast iron skillet. This little gem makes it so easy to start the base of this casserole on the stove top and then finish it off in the oven. No need to dirty up a pan and then also a casserole dish!

Shredded chicken is added to the skillet with the veggies and homemade cream of chicken soup.

To make this veggie and chicken casserole recipe you will need to have 2 cups of shredded or chopped cooked chicken, this is about equal to a little less than a pound of chicken breasts. You can use white or dark meat chicken and leftover chicken works great for this recipe. It really helps speed things along. If you are the kind of person who likes to cook in bulk and freeze meat to use later this is the casserole for you.

The last component added to the chicken zucchini casserole is stuffing mix.

Zucchini, celery, onions and shredded carrots play the supporting roles in this casserole. I like to buy the matchstick carrots because they cut out the time of having to shred carrots. If you don’t have some of these vegetables on hand yellow squash, mushrooms, or green beans would also make great substitutions.

The last major player in this dish is the stuffing. Stove Top Savory Herb stuffing is what is pictured, but you can use just about any flavor of stuffing mix in this recipe, even cornbread stuffing.

How to make chicken zucchini casserole.

Step 1, Melt butter in a large cast iron skillet on medium heat and cook the vegetables until they begin to soften. Add the flour to the mixture and stir until it’s dissolved. It will kind of look like a gloppy mess and that’s okay! It’s supposed to!

Step 2, Slowly add the broth and milk. Whisk and stir until the mixture is thick and bubbly.

Step 3. Stir in the shredded chicken, stuffing mix, and sour cream. Season with salt and pepper.

Step 4. Slide it in the oven and bake it for 40 minutes or until the top is golden brown.

If you don’t have a cast iron skillet, it’s still easy to make this recipe. Instead of baking the casserole in the skillet, after step 3 simply transfer the mixture to a 9 x 13 baking dish.

Chicken Zucchini Casserole

Prep Time: 15 minutes
Cook Time: 40 minutes
Total Time: 55 minutes

Chicken, vegetables and stuffing are tossed with a creamy homemade sauce and then baked in the oven.

Ingredients

  • 3 Tablespoons Butter
  • 2 cups zucchini, chopped
  • 1 cup shredded carrots
  • 1/2 cup celery, finely chopped
  • 1/2 cup onion, finely chopped
  • 3 Tablespoons all purpose flour
  • 1 14.5 ounce can chicken broth
  • 1/2 cup milk
  • 2 cups shredded chicken
  • 1/2 cup sour cream
  • 1 box stuffing mix
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper

Instructions

  1. Preheat the oven to 350 degrees. In a large cast iron skillet, melt the butter over medium heat. Add the zucchini, carrots, onion and celery. Cook and stir until the vegetables begin to soften. About 5- 7 minutes.
  2. Sprinkle the flour over the vegetables and stir until it's dissolved. The flour and veggies will all clump together and this is normal. Slowly add the broth and milk to the mixture, stirring constantly. Cook and stir, making sure to scrape the bottom of the pan until the mixture is thick and bubbly.
  3. Stir the chicken, sour cream and stuffing mix into the vegetables and sauce and season with salt and pepper. If you don't have a cast iron skillet, transfer the mixture to a greased 9x13 pan, otherwise place the cast iron skillet in the oven and bake uncovered for 40 minutes or until the top is golden brown.

Fantastic Kathy! If you have any more zucchini and chicken leftover I have one more easy skillet dinner that uses both on the site, Skillet Chicken and Orzo. So glad to hear you enjoyed the casserole!
