Ingredients
- 1 pound of cooked chicken, diced (rotisserie chicken works great)
- 1 cup carrots, diced
- 1 cup celery, diced
- 1 cup frozen peas
- 1 medium onion, chopped
- 3 cloves garlic, minced
- 1/4 cup butter
- 1/3 cup all-purpose flour
- 2 cups chicken broth
- 1 cup milk
- 1 teaspoon dried thyme
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 can of refrigerated pie crusts (or homemade if you prefer)
- 1 egg, beaten (for egg wash)
Directions
- Preheat your oven to 425°F (220°C).
- In a large skillet over medium heat, melt the butter. Add the chopped onion, celery, and carrots. Sauté until the vegetables are soft, about 5-7 minutes.
- Stir in the minced garlic and cook for an additional minute until fragrant.
- Sprinkle the flour over the vegetables, stirring continuously for about 1 minute to create a roux.
- Gradually whisk in the chicken broth and milk, ensuring there are no lumps. Continue to stir until the mixture thickens, about 3-5 minutes.
- Add the cooked chicken, frozen peas, thyme, salt, and pepper. Mix well to combine, and remove the skillet from heat.
- In a greased 9×13-inch baking dish, pour the chicken mixture evenly.
- Roll out the pie crust and place it over the chicken filling. Crimp the edges to seal and make a few slits in the top crust for steam to escape.
- Brush the top crust with the beaten egg to give it a golden finish.
- Bake in the preheated oven for 30-35 minutes, or until the crust is golden brown.
- Allow the casserole to cool for a few minutes before serving.

Variations to Consider
While the classic Chicken Pot Pie Casserole is already a delightful dish, here are some variations you might consider:
- Substitutions for Protein: Instead of chicken, you can use turkey or even tofu for a vegetarian option. Just ensure the tofu is well-pressed and cubed.
- Add More Veggies: Feel free to sneak in more vegetables such as green beans, corn, or bell peppers for added nutrition and flavor.
- Spice It Up: For those who enjoy a kick, adding a dash of hot sauce or red pepper flakes can elevate the flavor profile.
- Different Herbs: Experiment with different herbs like rosemary or parsley to suit your taste.
Serving Suggestions
Chicken Pot Pie Casserole is filling on its own, but here are some ideas to enhance your meal:
- Serve with a fresh garden salad to balance the richness.
- Pair with crusty bread to soak up the creamy sauce.
- Consider a side of roasted vegetables for a colorful and nutritious addition.
Storage Instructions
If you find yourself with leftovers (which is often the case with this delightful casserole), here’s how to store it properly:
- Refrigerate: Cover the casserole tightly with plastic wrap or foil and store it in the refrigerator for up to 3-4 days.
- Freeze: To freeze, make the casserole in advance without baking it. Wrap it tightly in plastic wrap, followed by aluminum foil. Freeze for up to 3 months. When ready to use, thaw it overnight in the refrigerator before baking as directed.
- Reheat: To reheat, place the casserole in a preheated oven at 350°F (175°C) until heated through. You may need to cover it with foil to prevent the crust from browning too much.
