Ingredients
Scale
- 1 package stuffing mix (6 ounces)
- 3/4 cup melted butter
- 3 cups chopped zucchini
- 2 cups cooked chicken breast, cubed
- 1 can condensed cream of chicken soup (10–3/4 ounces, undiluted)
- 1 medium carrot, grated
- 1/2 cup diced onion
- 1/2 cup sour cream
Instructions
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with nonstick spray or a thin layer of butter. Having a hot, even oven ensures the casserole bakes uniformly and develops that signature golden crust.
- Make the Stuffing Base: In a medium bowl, combine the dry stuffing mix with the melted butter. Stir until every crumb is evenly coated. The mixture should look like damp sand with no dry pockets. Set it aside for now—this will become the crispy top and buttery bottom layer.
- Sauté Aromatics: In a large skillet over medium heat, sauté the diced onion until translucent, about 3 minutes. Add the grated carrot and cook for 1 more minute, stirring constantly. Sautéing means cooking quickly in a small amount of fat over medium-high heat, which softens the vegetables and deepens their sweetness without browning.
- Build the Creamy Mixture: In a large mixing bowl, whisk together the undiluted cream of chicken soup and sour cream until smooth. Fold in the sautéed onion and carrot, then gently stir in the cubed chicken and chopped zucchini. I’ve found that using room-temperature sour cream prevents lumps from forming in the sauce.
- Layer the Casserole: Spread half of the stuffing mixture evenly across the bottom of the greased baking dish. Press it down lightly with a spatula to form an even base. This bottom layer soaks up the flavorful juices and becomes tender as it bakes.
- Add the Filling: Spoon the chicken-zucchini-cream mixture over the stuffing base, spreading it evenly. Use a spatula to reach all the corners, ensuring every bite has equal amounts of chicken and veggies. The filling should look creamy and chunky, with visible flecks of carrot and onion.
- Finish with Topping: Sprinkle the remaining stuffing mixture over the top in an even layer. Do not press it down—this allows it to stay crispy and light during baking. For extra crunch, you can drizzle a tablespoon of melted butter over the top (optional).
- Bake the Casserole: Place the dish in the preheated oven and bake uncovered for 30–35 minutes. A visual cue for doneness is the top turning deep golden brown and the filling bubbling at the edges. In my tests, the zucchini releases some moisture, creating a luscious, creamy sauce that prevents the casserole from drying out.
- Rest and Serve: Remove the casserole from the oven and let it rest for 5 minutes. This short rest allows the layers to set, making slices easier to serve without falling apart. Garnish with fresh parsley if desired, then spoon onto plates while still warm. Unlike chicken and rice casseroles, this one keeps its texture well the next day.
