Ingredients List for Chicken Pot Pie Casserole

To make this Chicken Pot Pie Casserole, you’ll need the following ingredients:

• 2 cups cooked, shredded chicken (rotisserie chicken works great)
• 1 cup frozen mixed vegetables (peas, carrots, and corn)
• 1 cup diced potatoes (optional, for extra heartiness)
• ½ cup diced onions
• ½ cup celery, chopped
• 2 cloves garlic, minced
• ¼ cup all-purpose flour (for thickening)
• 2 cups chicken broth (low sodium preferred)
• 1 cup heavy cream (or milk for a lighter version)
• ½ teaspoon thyme
• ½ teaspoon rosemary
• Salt and pepper to taste
• 1 package refrigerated biscuit dough (or puff pastry for the topping)
• 2 tablespoons unsalted butter (for sautéing vegetables)

Substitutions and Variations

This Chicken Pot Pie Casserole recipe is quite versatile, and you can easily adapt it to your taste or what you have on hand:

• Vegetables: You can switch out the frozen mixed vegetables for fresh vegetables or any leftovers you have in the fridge. Mushrooms, green beans, or bell peppers are great additions.
• Chicken: If you don’t have chicken, you can use turkey, which is perfect for using up leftovers after Thanksgiving. For a vegetarian option, substitute the chicken with chickpeas or tofu.
• Topping: While biscuit dough or puff pastry is traditional, you can top the casserole with mashed potatoes for a “shepherd’s pie” twist.
• Cream: If you want a lighter version, replace heavy cream with half-and-half or milk. You can also use coconut milk for a dairy-free version.

Step-by-Step Cooking Instructions

1. Preheat your oven to 375°F (190°C).
2. Cook the vegetables: In a large skillet, melt the butter over medium heat. Add the onions, celery, and garlic, and sauté until soft, about 4-5 minutes.
3. Add the flour: Stir in the flour to create a roux, cooking for 1-2 minutes to get rid of the raw flour taste. This helps to thicken the casserole filling.
4. Make the sauce: Slowly whisk in the chicken broth and heavy cream. Stir constantly until the mixture is smooth and starts to thicken. Season with thyme, rosemary, salt, and pepper.
5. Add chicken and vegetables: Stir in the cooked chicken, frozen mixed vegetables, and diced potatoes (if using). Cook until the mixture is heated through and the sauce is thick and creamy.
6. Transfer to a casserole dish: Pour the chicken and vegetable mixture into a greased 9x13-inch casserole dish, spreading it evenly.
7. Top with biscuit dough: Arrange the biscuit dough or puff pastry on top of the chicken mixture, covering the entire surface.
8. Bake: Bake the casserole in the preheated oven for 25-30 minutes, or until the biscuits are golden brown and the filling is bubbling.

How to Cook Chicken Pot Pie Casserole: A Step-by-Step Guide

1. Prepare the Chicken: Whether you’re using rotisserie chicken or leftover cooked chicken, make sure it’s shredded or chopped into bite-sized pieces. You’ll need about 2 cups of cooked chicken.
2. Create the Sauce: The creamy sauce is the key to a delicious Chicken Pot Pie Casserole. Sauté the onions, celery, and garlic in butter before adding flour to create a thick base. Slowly whisk in chicken broth and cream for a rich, savory sauce that binds the casserole together.
3. Layer the Ingredients: Once your filling is ready, transfer it to your casserole dish. Make sure to spread it out evenly so every bite has a balance of chicken, vegetables, and creamy sauce.
4. Top with Dough: The biscuit or puff pastry topping adds that essential flaky, golden layer. Lay the dough carefully over the top of the casserole, and make a few small slits if you’re using puff pastry to allow steam to escape.
5. Bake Until Golden: Bake the casserole until the top is golden brown and the filling is bubbling. This should take around 25-30 minutes, but keep an eye on it to avoid burning.

Common Mistakes to Avoid

1. Not Thickening the Sauce: One of the most common mistakes is not cooking the flour long enough when making the roux. If the sauce is too runny, your casserole will be soupy rather than creamy.
2. Overcooking the Vegetables: Frozen vegetables don’t need much cooking, so make sure not to overcook them before baking the casserole. They should still have a bit of texture when the dish is done.
3. Undercooking the Dough: Whether you’re using biscuits or puff pastry, it’s important to bake until the top is fully cooked and golden brown. Check the middle of the casserole to ensure the dough isn’t raw underneath.
4. Using Too Much Liquid: Be careful not to add too much broth or cream, as this can result in a casserole that’s too runny. The sauce should be thick enough to coat the back of a spoon.

Serving and Presentation Tips

The best part about a Chicken Pot Pie Casserole is how hearty and satisfying it is, but a little attention to presentation can make it extra special. Here are a few tips:

• Garnish with fresh herbs: Sprinkle some fresh parsley or thyme over the top before serving to add a pop of color and fresh flavor.
• Serve in bowls: Since this is a creamy casserole, it’s best served in bowls to catch all the delicious sauce. This also makes it easier to eat with a spoon!
• Pair with a side salad: A light, fresh salad with a tangy vinaigrette pairs beautifully with the rich flavors of the casserole.

How to Serve Chicken Pot Pie Casserole

Chicken Pot Pie Casserole is best served hot from the oven. Use a large spoon to scoop out portions, making sure each serving gets some of the flaky topping and creamy filling. You can serve it with crusty bread to soak up any extra sauce, or a light green salad to balance out the richness of the casserole. For a more rustic, family-style presentation, simply place the casserole dish in the middle of the table and let everyone serve themselves.

Presentation Ideas for Chicken Pot Pie Casserole

To make your Chicken Pot Pie Casserole visually appealing, here are a few presentation ideas:

• Top with decorative pastry cuts: If you’re using puff pastry, consider cutting out small shapes like leaves or stars to place on top of the casserole before baking.
• Use individual ramekins: For a more elegant presentation, you can bake the casserole in individual ramekins. This makes serving easier and gives each person their own personal pot pie.
• Serve with rustic bread: A side of artisan bread or dinner rolls can be placed alongside the casserole for a homestyle, cozy vibe.

Chicken Pot Pie Casserole Recipe Tips

• Make it ahead: You can assemble the entire casserole up to a day in advance and store it in the fridge. When you’re ready to bake, simply add the biscuit topping and pop it in the oven.
• Freeze for later: This casserole freezes beautifully. To freeze, let it cool completely after baking, then cover tightly with foil and freeze for up to three months. When ready to eat, thaw overnight in the fridge and reheat in the oven.
• Add cheese: For a cheesy twist, sprinkle shredded cheddar or Parmesan over the top of the filling before adding the biscuit or puff pastry topping.
