Key Ingredients for Your Casserole
To make this mouthwatering casserole, you’ll need:
- 1 lb ground chicken (or rotisserie/shredded chicken)
- 1/2 cup onion, diced
- 3/4 cup butter, melted
- 6 oz package Herb Stuffing Mix
- 3 cups zucchini, diced
- 10 oz can Cream of Celery soup
- 1/2 cup sour cream
Feel free to add optional ingredients like shredded parmesan cheese, shredded carrots, or a dash of black pepper to elevate the flavor and nutrition.
Assembling Your Chicken Zucchini Casserole
Preparing the Chicken and Onion Base
Start by preheating your oven to 350°F. While it heats, spray a casserole dish with non-stick cooking spray. In a skillet over medium-high heat, cook the ground chicken and diced onion. Stir until the chicken is thoroughly cooked through, about 5-7 minutes. If there’s excess liquid, make sure to drain it. Season the mixture with black pepper to enhance the flavor.
Mixing the Casserole Filling

In a mixing bowl, combine the melted butter and the dry stuffing mix. Set aside half a cup of this mixture for the top later. Now, stir in the diced zucchini, cream of celery soup, and sour cream into the remaining stuffing mix, combining everything until well blended. This creamy filling is where the magic happens!
Creating the Topping
Take the reserved stuffing mix and sprinkle it over the top of your casserole filling. This will create a deliciously crispy topping that contrasts perfectly with the creamy mixture underneath.
Baking Instructions
Spread the entire mixture evenly into the prepared casserole dish. Place it in the preheated oven and bake for approximately 25 minutes, or until the top is golden brown and crispy. The aroma that fills your kitchen will make your mouth water as you anticipate this hearty meal!
Tips and Variations for Your Casserole
Ingredient Substitutions
Don’t have ground chicken? You can easily substitute it with shredded rotisserie chicken or leftover cooked chicken. If you prefer a different flavor, feel free to use other cream soups in place of the cream of celery. The stuffing mix provides a robust flavor and sufficient salt, so you won’t need to add much more seasoning.
Adding Extra Flavor and Vegetables
For added nutrition, consider adding shredded carrots into the filling. This brings a lovely sweetness and extra color to your casserole. A sprinkle of shredded parmesan or sharp white cheddar cheese on top before baking can also take the flavor to a new level. It’s all about personalizing your dish!
