A splash of heavy cream

How to Make a Creamy Chicken Pot Pie Casserole

Step 1: Prepare the Filling

Melt butter in a large pot or skillet.
Add chopped onions, carrots, celery, and peas.
Cook until slightly softened.

Sprinkle flour over the vegetables to create a roux.
Cook for 1–2 minutes to eliminate raw flour taste.

Slowly pour in chicken broth while whisking.
Add milk or cream.
Simmer until thickened and glossy.

Season generously:

Salt
Black pepper
Garlic powder
Warm spices like thyme or rosemary add depth.

Step 2: Add Chicken

Mix in shredded cooked chicken.
Stir well to combine.

This filling should be:

Thick
Creamy
Smooth
Well-seasoned

If it looks too thick, add a splash of broth.
If it looks too thin, simmer longer.

Step 3: Transfer to a Casserole Dish

Pour the mixture into a greased 9×13 baking dish.
Spread evenly.

Step 4: Add the Topping

You can top it with:

Biscuit dough
Puff pastry sheet
Pie crust
Buttery crushed cracker mixture

For biscuits:
Place biscuit dough on top, leaving a little space between each to help them rise.

For puff pastry:
Lay the pastry sheet over the casserole and cut small slits for steam.

Step 5: Bake

Bake at 375°F (190°C) until the topping is golden brown and cooked through.

Timing depends on the topping:

Biscuits: 20–25 minutes
Puff pastry: 25–30 minutes
Pie crust: 30–35 minutes
Crackers: 15–20 minutes

Step 6: Rest Before Serving

Let the casserole rest for 10 minutes after baking.

This helps the filling thicken so it doesn’t spill everywhere.

Common Mistakes and How to Fix Them
