  • Zucchini (4 diced) – Contributes nutrition and texture. Yellow squash can be used as a substitute.

How to Make Chicken Zucchini Casserole

  1. Preheat the oven to 350°F (175°C). This temperature ensures your casserole cooks evenly, resulting in a perfectly creamy and golden dish.

  2. Mix the stuffing mix with the melted butter in a large bowl, setting aside ½ cup of the mixture for topping later. The butter adds richness and binds the stuffing.

  3. Combine the diced zucchini, cooked chicken, mozzarella cheese (if using), cream of chicken soup, diced onion, and sour cream into the bowl. Mix well until everything is coated, creating a flavorful base.

  4. Spread the mixture evenly in a greased 9×13 inch baking dish. This will allow for even cooking and browning as it bakes.

  5. Top the casserole with the reserved stuffing mixture. This will create a delightful crispy layer on top, balancing the creamy filling beneath.

  6. Bake uncovered for 40-50 minutes, or until the casserole is cooked through and the top is golden brown. You’ll know it’s ready when you see bubbling edges and a lovely crust forming.

Optional: Sprinkle with fresh parsley for a pop of color and freshness before serving.
