Can I make Ina Garten Chicken Casserole Recipe ahead of time?

Yes! Assemble the filling in the dish, cover, and refrigerate up to 24 hours . Add the breadcrumb topping right before baking for the best crunch.

How do I store leftovers?

Store in an airtight container in the fridge for 3–4 days . Reheat in the oven (best for crisp topping) or microwave (best for speed and sanity).

You can. Freeze the casserole before baking (without the breadcrumb topping if possible). Thaw overnight in the fridge, add topping, and bake. If freezing after baking, the topping may soften—but it will still taste amazing.

What’s the best chicken to use?

Rotisserie chicken is the easiest. Leftover roasted chicken is also fantastic. If you’re cooking chicken just for this, simple baked or poached chicken works great.

Absolutely. Not everyone loves peas (I see you). Try corn, chopped green beans, or even sautéed mushrooms.

Instructions

Preheat the oven to 375°F and grease a 9×13-inch baking dish.
Melt 4 tablespoons butter in a large skillet over medium heat. Add the onion, carrots, and celery. Cook for 5 to 7 minutes until softened.
Stir in the garlic and cook for 1 minute until fragrant.
Sprinkle the flour over the vegetables and stir for 1 to 2 minutes to make a roux.
Gradually whisk in the chicken stock, then the heavy cream. Cook for 3 to 5 minutes, stirring often, until the sauce thickens.
Remove from the heat and stir in the cooked chicken, peas, thyme, Parmesan cheese, salt, and black pepper.
Transfer the mixture to the prepared baking dish and spread it into an even layer.
In a small bowl, mix the breadcrumbs, melted butter, and Parmesan cheese for the topping.
Sprinkle the topping evenly over the casserole.
Bake for 25 to 30 minutes, until the top is golden brown and the filling is bubbling.
Let the casserole rest for 5 minutes before serving. Garnish with chopped parsley if desired.

Notes

Rotisserie chicken works beautifully here and saves time.

For extra flavor, use freshly grated Parmesan.

You can assemble the casserole ahead of time and refrigerate it for up to 24 hours before baking.

If the topping needs more color, broil for 1 to 2 minutes at the end.

Leftovers keep well in the fridge for up to 4 days.
