This casserole is loaded with the tastiest sauce, chunky chicken, peas, carrots, and more, and topped with a beautiful lattice pie crust. I love how homey, delicious, fun, and comforting it is. It has all the flavor of my favorite classic chicken pot pie, but it’s there for me when I need something less fussy!
What’s in this Chicken Pot Pie Casserole Recipe?
- Pie Crust: For this recipe, I love that I only need one pie crust to place on top of the pie– so easy!
- Butter + Oil: Olive oil helps the veggies cook without burning, while butter infuses them with a rich flavor.
- Mirepoix: Carrots, celery, and onion create a flavorful, vegetal base for this dish.
- Garlic: Adds an earthy flavor.
- Chicken: Pot pie is the perfect recipe to use up leftover cooked chicken. I cubed mine, but shredded chicken also works well!
- Mushrooms: Add a rich umami flavor.
- Peas: Add a pop of color and sweetness.
- All-Purpose Flour: Thickens the gravy.
- Chicken Broth: Combines with the fat and drippings to create a rich gravy.
- White Wine: Adds a touch of acidity and freshness. You can use a splash of vinegar and more chicken broth if you prefer.
- Heavy Cream: Makes this pot pie thick and creamy. You can use half-and-half to lighten it up a bit.
- Spices: Kosher salt, black pepper, thyme, and basil enhance the flavors of this dish.
- Egg: Combines with water to create an egg wash that gives the crust a rich golden brown color.

Tips for Success
- For a gluten-free pie, use a gluten-free pie crust and gluten-free 1:1 all-purpose flour.
- For a dairy-free pie, use dairy-free butter and coconut cream or soy-based heavy whipping cream.
- If you like your filling a bit thicker, continue simmering until it thickens to the desired consistency.
- Try to keep the crust relatively taut over the baking pan so that it doesn’t touch the filling. If it is sitting directly on the filling, it may take longer to bake due to the extra moisture.
- If you notice that the pot pie crust is browning too quickly, loosely cover the pot pie with foil halfway through baking.
How to Store and Reheat
Store: Store leftover chicken pot pie casserole in an airtight container in the refrigerator for up to 3 days. Reheat in a 375°F oven for 25-30 minutes, or until warmed through.
Freeze: You can freeze chicken pot pie casserole both before and after baking. Just be sure to do so in a non-glass baking dish to prevent it from shattering. Tightly wrap the casserole in 2 layers of plastic wrap and 1 layer of aluminum foil and freeze for up to 2 months.
Reheat: To reheat an already-baked frozen pie, place it in a 375°F oven for 30-35 minutes. To bake from frozen, bake in a preheated oven with the foil on for 30 minutes, then remove the foil and continue to bake for 45-50 minutes, until golden brown and 165°F internally.
Serving Suggestions
This chicken pot piecasserole is a meal all by itself. But because this casserole doesn’t have a second crust, you could serve it over a bed of mashed potatoes, rice, or cauliflower. A fresh green salad or some roasted vegetables on the side would also be delish! For something a little lighter, consider some coleslaw.

How to Make Chicken Pot Pie Casserole Step by Step
Prep and Melt the Fats: Preheat the oven to 375°F and spray a 2-quart casserole dish with nonstick spray. Set aside. Allow a 9-inch pie crust to warm at room temperature for 15-20 minutes before rolling out. Meanwhile, heat 4 tablespoons of unsalted butter and 2 tablespoons of olive oil in a skillet set over medium-high heat until they shimmer.
Sauté the Veggies: Add 2 diced carrots and 2 diced ribs of celery and cook for 3 minutes. Add 2 minced sweet onion and cook until onion is translucent, then add 2 cloves of minced garlic and cook for 30 seconds.
Add the Chicken: Add 3 cups of cubed, cooked chicken, 4 ounces of diced mushrooms, and 1 cup of frozen peas and cook for 1 minute.
Coat with Flour: Sprinkle the vegetables and chicken with ¼ cup of all-purpose flour and cook for 3 minutes, stirring continuously.
Deglaze the Pan: Stir in 2 cups of low-sodium chicken stock and scrape the bottom of the pan to deglaze the pan.
Season the Filling: Pour in ¼ cup of white wine and 1 cup of cream. Stir well. Season with ½ teaspoon of kosher salt, 1 teaspoon of freshly ground black pepper, ½ teaspoon of dried thyme, and ¼ teaspoon of ground sweet basil. Stir well and continue to cook until thickened to a thick-stew consistency.
Fill the Casserole Dish: Pour the chicken stew mixture into the prepared casserole dish.
Top with Pie Crust: Roll the pie crust to ¼-inch thickness and into 1-inch strips to create a lattice top. Or, drape it over the chicken stew mixture, and trim or crimp in the sides.
Egg Wash the Crust: Combine 1 large egg and 1 teaspoon of water and brush the pastry with the egg mixture.
Bake the Casserole: Bake on the center rack of the oven for 35-45 minutes, or until the top is golden.
Love this recipe, I’ve made it several times in past year. This one is a keeper!
Yay! So happy it’s become a regular dish for you!
If I am not including mushrooms, as me and my kiddos do not care for them, what should I substitute in order to have the same consistency?
Thanks! I am hoping to make this tonight!! :)
Thank you so much.![5 stars](data:image/gif;base64,R0lGODdhAQABAPAAAP///wAAACwAAAAAAQABAEACAkQBADs=)

That is awesome! Thanks so much for letting me know :)
This was phenomenal! Pot pies are one of my boyfriends favorite meals so, I decided to give it a try. I used the second crust for the bottom to make it an actual pie. I sprayed the whole dish and then fit it in nicely. I also added a ton of rosemary when seasoning to give it a savory, homey taste. I added the frozen peas towards the end. I figured they didn’t need as much cooking time as the carrots and celery. I also found that I needed a little more flour than the 1/4 to get it as thick as I wanted. All in all, this was a hit and I will definitely make it again!![5 stars](data:image/gif;base64,R0lGODdhAQABAPAAAP///wAAACwAAAAAAQABAEACAkQBADs=)
