Chicken Pot Pie Casserole vs Classic Chicken Pot Pie
Classic chicken pot pie is baked inside a pastry crust with top and bottom layers. It requires rolling dough and careful baking to avoid undercooked or soggy crust.
Chicken pot pie casserole simplifies everything. The creamy filling is layered in a baking dish and topped with biscuits or pastry before baking. It is faster, easier, and more forgiving.
Choose traditional pot pie for holidays or special dinners. Choose chicken pot pie casserole when you want the same comfort flavor with less prep time and more reliable results.
How to Make Chicken Pot Pie Casserole
** You can find the full recipe ingredients and instructions on the printable recipe card below.
This recipe comes together in two simple parts. First, you prepare the creamy chicken filling. Then you add the topping and bake until golden and bubbly.
Oven Method
- Preheat oven to 375 degrees. Lightly grease a 9 by 13 inch baking dish.
- In a large bowl, combine cooked chicken, frozen mixed vegetables, cream of chicken soup, milk, and seasonings. Stir until evenly mixed.
- Spread the mixture evenly into the prepared baking dish.
- Arrange biscuit dough evenly over the top of the filling.
- Bake for 30 to 40 minutes, until the filling is bubbling around the edges and biscuits are golden brown and cooked through.
- Let rest for 5 to 10 minutes before serving to allow the sauce to thicken slightly.
Doneness cue: The center should be hot and bubbling, and biscuits should have no doughy center.
Puff Pastry Option
For a chicken pot pie casserole with puff pastry, prepare the filling as directed.
- Spread filling into the baking dish.
- Lay a thawed puff pastry sheet over the top. Trim edges if needed and cut small vents to release steam.
- Bake at 400 degrees for 25 to 30 minutes until the pastry is golden brown and crisp.
This option creates a flakier, more traditional pot pie texture.
Optional Thickening Tip
If the filling seems too thin before baking, stir in 1 tablespoon flour or cornstarch mixed with 1 tablespoon cold water.
If the casserole thickens too much after baking, stir in 1 to 2 tablespoons warm milk before serving.
What Can Go Wrong and How to Fix It
- Too thin – Let the casserole rest for 10 minutes after baking so the sauce sets. If needed, add a cornstarch slurry before baking.
- Too thick – Stir in a splash of milk or chicken broth to loosen the filling.
- Bland – Add additional salt, black pepper, garlic powder, or poultry seasoning.
- Dry or overcooked – Cover loosely with foil if the topping browns too quickly.
- Soggy topping – Make sure the filling is hot before adding pastry and bake until fully golden.
- Separated sauce – Stir thoroughly before baking and avoid overheating dairy.
Ingredients and What They Do
** You can find the full recipe ingredients and instructions on the printable recipe card below.
Cooked chicken – Provides protein and hearty texture.
- Frozen mixed vegetables – Add color, sweetness, and balance.
- Cream of chicken soup – Creates the creamy base and classic pot pie flavor.
- Milk – Thins and smooths the sauce.
- Seasonings – Enhance depth and warmth.
- Refrigerated biscuits or puff pastry – Create the golden baked topping.
Ingredient Substitution Notes
- Use rotisserie chicken for convenience or substitute leftover turkey.
- Swap cream of mushroom soup for a slightly different flavor profile.
- Use half-and-half instead of milk for a richer filling.
- For a lighter version, use reduced fat soup and low fat milk.
- For a homemade option, replace canned soup with a thick white sauce made from butter, flour, broth, and milk.
Recipe Tips
- Cut chicken into evenly sized pieces for consistent texture.
- Space biscuits evenly so they bake through completely.
- If biscuits brown too fast, tent loosely with foil.
- For make-ahead preparation, assemble filling and refrigerate up to 24 hours before topping and baking.
- Allow the casserole to rest before serving so the filling thickens properly.
What to Serve With Chicken Pot Pie Casserole
If you are wondering what to serve with chicken pot pie casserole, choose lighter sides to balance the creamy filling.
Storage

- Reheat individual portions in the microwave until hot. For best texture, reheat in the oven at 350 degrees until warmed through.
- Freeze without the biscuit topping for up to 2 months. Thaw overnight and bake with fresh topping.
Time Saving Swaps

Chicken Pot Pie Casserole
Ingredients
- 2 sheets frozen puff pastry
- 1 egg , beaten
- 4 chicken breast halves , or 2 cups leftover cooked chicken
- Seasoned salt and pepper
- 2 tablespoons cooking oil
- 1/3 cup butter
- 1/3 cup all-purpose flour
- 1 quart (4 cups) heavy cream
- 4 tsp chicken base (sold near the bouillon) See Notes**
- 1 tablespoon minced garlic
- 1/2 small yellow onion , minced
- 1 cup frozen green peas , cooked
- 1 cup chopped cooked carrots
- Pinch fresh grated nutmeg , optional
Instructions
- Preheat oven to 350° F.
- Season chicken with seasoned salt and pepper. Heat oil in a large skillet over medium-high heat. Add chicken and saute until cooked through. Remove from heat and cut into chunks. Alternatively, you may use precooked chicken. Once cooked, remove chicken from pan and set aside.
- Meanwhile, Cut each sheet of frozen puff pastry into 1-inch strips. On a large cookie sheet, weave strips into a lattice large enough to cover the 8-inch x 8-inch pie dish. Brush the beaten egg onto the lattice square. Bake for 10 minutes, or until dough has risen and turned light golden brown. Remove from the oven and set aside until ready to assemble the casserole.
- Into the same large skillet, melt butter and then slowly add flour, stirring until consistency of peanut butter, but do not brown like a roux — you want it to remain a golden color. Slowly add cream and keep stirring. Add chicken base, garlic, and onion and stir until thickened. Add peas, carrots, nutmeg (optional), and cut up chicken. Remove from heat. Pour the hot mixture into an 8-inch x 8-inch oven-proof pan or pie dish and top with the pre-cooked lattice square. Bake for 5 minutes or until bubbly. Any remaining pie filling may be frozen.

Thanks this great recipe!!! Can’t wait to try it!! Everything you do is spot on.
Made in individual dishes for Father’s Day lunch. Dad’s and grandpas all agreed it was very tasty.
Made this in ramekins as another reviewer suggested and served it for Father’s Day lunch. Very delicious. Both dads, grandads loved it
This was really good. I liked that it doesn’t taste like a traditional pot pie but so much more luxurious. I would serve this in individual ramekins for guests next time.
Hi Sandee, thanks for your kind words. I’m so glad you enjoyed it.
I’ve read both of your Chicken Pot Pie Soup and Chicken Pot Pie Casserole recipes and they do sound very tasty, so I’ll be trying them very soon. I am, however, a little confused about the casserole recipe. In your comments about chicken base, you note that it’s critical to follow the instructions for the base – which ever one you are using. In the case of the Orrington Farms base, it’s 1 tsp of base to 1 cup fluid. So here’s where the confusion sets in: the Pot Pie recipe calls for 1/4 cup [or 12 tsps] of base, yet there are only 4 cups of fluid [the heavy cream] in the recipe. If one were to add the requisite 12 cups of fluid, then we’d be back to the Chicken Pot Pie Soup, rather than a casserole! So … which of your directions do I follow?? Off hand, I don’t remember the name of the base that I normally use, but as I recall, it also calls for 1 cup of fluid per tsp of base, so I imagine that altering that 1 tsp: 1 cup ratio would hold true for it as well. Maybe? Help!!
Hi El,
Bad math! I’ve updated the recipe to reflect 4 tsp instead of 4 Tbsp (1/4 cup). Thank you for taking the time to point that out! I appreciate it so very much.
Can you make this and freeze?
Hi Toni, since this recipe comes together so quickly, I have not taken the time to make it ahead and freeze. I would like to think it would freeze without separation like a store bought pot pie but cannot in full certainty guarantee those results as I have not yet tried it. I’m sorry I could not be of more help on this topic. Maybe another reader can chime in and enlighten us! Thank you for taking the time to comment, I appreciate it.
I have frozen it and then defrosted to reheat and use in vol-au-Vons’s. As delicious then as it was originally.
Thanks, Pamela. I appreciate you stopping to take the time to comment. We appreciate your help!
