This hearty casserole is a simple and delicious way to use up leftover chicken.

Step 4: Assemble the Casserole

1. Spread the cooked rice, pasta, or mashed potatoes evenly on the bottom of the prepared baking dish.
2. Pour the creamy chicken and vegetable mixture over the base, spreading it evenly.
3. Sprinkle the remaining ½ cup of cheddar cheese on top.

Step 5: Prepare the Topping

1. In a small bowl, mix the breadcrumbs (or crushed crackers) with the melted butter.
2. Add Parmesan cheese if desired, and stir until well combined.
3. Sprinkle the topping evenly over the casserole — this will create a crispy, golden finish.

Step 6: Bake to Perfection

1. Cover the casserole loosely with aluminum foil to prevent over-browning.
2. Bake in the preheated oven for 20 minutes.
3. Remove the foil and bake for an additional 15–20 minutes, or until the topping is golden brown and the casserole is bubbling.
4. Let the casserole rest for 5 minutes before serving — this allows the flavors to meld and makes it easier to slice.
