Step‑by‑Step Instructions for Hearty Chicken and Broccoli Stuffing Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking dish with cooking spray or butter. This ensures your Hearty Chicken and Broccoli Stuffing Casserole won’t stick to the dish and will turn golden as it bakes. Gather your ingredients while the oven warms up, creating an inviting atmosphere in your kitchen.
Step 2: Prepare the Stuffing
In a medium saucepan, combine 1 ½ cups of low-sodium chicken broth and ¼ cup of unsalted butter. Bring this mixture to a gentle boil over medium heat. Once boiling, remove it from the heat and stir in the 6 ounces of stuffing mix. Cover the pan and let it rest for 5 minutes, allowing the stuffing to absorb all that flavorful broth before fluffing it with a fork.
Step 3: Cook the Vegetables
While the stuffing rests, melt the remaining ⅛ cup of unsalted butter in a medium skillet over medium heat. Add in the diced ½ cup of celery and ½ cup of white onion, cooking for about 4-5 minutes until the vegetables are softened and fragrant. This step enhances the savory base of your casserole, providing depth to the overall flavor of the dish.
Step 4: Combine the Filling
In a large mixing bowl, transfer the sautéed celery and onion, then add in 2 cups of shredded rotisserie chicken, 2 cups of broccoli florets, and 2 cans of cream of chicken soup. Mix everything until it’s well combined, creating a beautiful filling packed with layers of flavor for your Chicken and Broccoli Stuffing Casserole.
Step 5: Assemble the Casserole
Transfer the creamy chicken and broccoli mixture into the greased baking dish, spreading it evenly. Next, sprinkle 1 cup of shredded cheddar cheese on top of this filling mixture to add a delightful melty layer. Finally, layer the prepared stuffing mix over the cheese, ensuring it covers the surface for that perfect crunchy topping after baking.
Step 6: Bake the Casserole
Cover your baking dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes to allow the flavors to meld. After 20 minutes, remove the foil to expose the casserole and continue baking for an additional 10-15 minutes. You’ll know it’s ready when the topping is golden brown and the edges are bubbling with deliciousness.
