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.
I’m making this now. But will not serve it till tomorrow. Should I make it up to the baking point?
Yes, then place it in the refrigerator until ready to bake! You may need to add an extra 5-10 minutes to the final baking time to make up for the cold start!
Thanks so much for your quick reply.![5 stars](data:image/gif;base64,R0lGODdhAQABAPAAAP///wAAACwAAAAAAQABAEACAkQBADs=)
I saved this as part of a ‘pre-make meal section’. Would this be ok to freeze as you are using cooked chicken in it?
Yes, you can absolutely freeze this!
I tried this recipe last week, it was a hit! Very nice……. thank you.![5 stars](data:image/gif;base64,R0lGODdhAQABAPAAAP///wAAACwAAAAAAQABAEACAkQBADs=)
Looks amazing!
WOW! You made it, sounds like it was a case of operator error. No one else is complaining of the massive amounts of disappointment in the way that you are. If you would rather eat a pre~made meal from the grocery store, as opposed to a meal that you make at home, using you own ingredients and your own skills, that definitely says something about you, not the recipe. But HEY!! GO WHOLE FOODS!! You got this lady roped in, she’s happy to drop her paycheck off at the checkout…
Im going to try this but i hate carrots and peas so, Im making it with brocolli, corn, mushroom and onions. I will use 2 pie crusts on the bottom and top.
Let us know how it goes!
This was so good – big hit in my house. I only had salted butter, so it came out more saltier than expected (but that was my error). Otherwise it was delicious and my husband asked if I can make again.![5 stars](data:image/gif;base64,R0lGODdhAQABAPAAAP///wAAACwAAAAAAQABAEACAkQBADs=)
Love to hear that!
I made this recipe and it turned out really well. My husband loved it and didn’t have any suggestions for improvement – Yay! I didn’t have white wine so left it out. I substituted 2% milk for the cream, used cooked frozen mixed vegetables, and reduced the amount of pepper to 3/4 tsp as I thought 1tsp was a lot. The sauce was a bit thin so I added a cornstarch slurry and that thickened it perfectly. Great recipe. Will make a again and again.😊![5 stars](data:image/gif;base64,R0lGODdhAQABAPAAAP///wAAACwAAAAAAQABAEACAkQBADs=)
Thanks for sharing, Ellen!
Awesome recipe! Husband loved it. For those concerned with liquidity, replace 1 Cup half/half or heavy cream with 1 cup cream cheese instead. Worked out great since I didn’t have the half/half or heavy cream.![5 stars](data:image/gif;base64,R0lGODdhAQABAPAAAP///wAAACwAAAAAAQABAEACAkQBADs=)
Thanks for sharing!
Added extra ingredients and spices to make it my own and BAM!![5 stars](data:image/gif;base64,R0lGODdhAQABAPAAAP///wAAACwAAAAAAQABAEACAkQBADs=)
Thanks fr sharing, Crissie!
The flavor was great!!! Your recipes are always a staple in our household! The only thing I did differently was use salted butter and added more chicken broth instead of white wine. I also should have just covered the filling with a whole pie crust instead of doing the lattice. The crust sank into the filling. Thank you for your flavorful recipes!!!![5 stars](data:image/gif;base64,R0lGODdhAQABAPAAAP///wAAACwAAAAAAQABAEACAkQBADs=)
Thanks for stopping by and sharing, Kelly!
