How to Make Chicken Pot Pie Casserole
Step 1: Preheat the Oven
Preheat your oven to 400 degrees F. Prepare a 9x13 baking dish by spraying it with nonstick spray to prevent sticking.
Step 2: Sauté Vegetables
In a large pot, melt 4 tablespoons of butter over medium heat. Add the diced onions and celery, cooking for about 5 minutes until they become soft and fragrant.
Step 3: Add Frozen Vegetables
Stir in the frozen mixed vegetables and continue to sauté for another 5 minutes. This will help bring out their flavors in the filling.
Step 4: Prepare the Filling
Sprinkle ½ cup of flour, salt, and cracked black pepper into the pot. Stir well for about 2 minutes to cook the flour slightly and remove the raw taste.
Step 5: Add Liquid Ingredients
Gradually pour in the chicken stock, stirring constantly until the mixture reaches a low boil. Reduce the heat and add the milk while continuing to stir until well combined.
Step 6: Incorporate Chicken
Add the cooked shredded chicken to the pot and let it simmer for 15 minutes. This allows the flavors to meld and thickens the filling.
Step 7: Transfer to Baking Dish
Pour the chicken filling into the prepared baking dish. Spread it evenly across the bottom.
Step 8: Make Biscuit Topping
In a separate bowl, mix together 3 cups of flour, baking powder, sugar, and sea salt. Grate in the frozen butter and mix until the mixture resembles coarse crumbs.
Step 9: Form Biscuit Dough
Add the buttermilk to the flour mixture and stir until a dough forms. Be careful not to overmix; this will keep the biscuits tender.
Step 10: Shape Biscuits
Turn the dough out onto a floured surface. Roll it out and cut it into 12 biscuits. Place the biscuits on top of the chicken filling, and brush them with the remaining 2 tablespoons of melted butter.
Step 11: Bake
Bake in the preheated oven for 20 minutes or until the biscuits are golden brown and the filling is bubbly. This creates a delicious contrast of textures.
Step 12: Rest and Serve
Remove from the oven and let the pot pie sit for 5 minutes before serving. This resting time helps to set the filling and makes it easier to serve.

Pro Tips from My Kitchen
✓ Chill the Ingredients – Cold butter is essential for flaky biscuits. Keep your butter and buttermilk in the fridge until you are ready to use them.
✓ Don’t Overmix – When preparing the biscuit dough, mix until just combined. Overworking the dough can lead to tough biscuits instead of tender ones.
✓ Test the Thickness – The filling should be thick but still pourable before you add the biscuits on top. If it’s too runny, let it cook down a bit more on the stove.
✓ Rotate the Dish – To ensure even baking, rotate the baking dish halfway through the baking time. This helps achieve an evenly golden crust on your biscuits.
✓ Experiment with Veggies – Feel free to swap out the frozen mixed vegetables for fresh veggies or your favorites. Adding in peas or corn can bring in different textures and flavors.
What Makes This Recipe Work
- The combination of sautéed onions, celery, and frozen vegetables provides a depth of flavor. This blend creates a rich and hearty filling that complements the chicken beautifully.
- Using both chicken stock and milk results in a creamy consistency. This balance keeps the filling flavorful without being overly heavy.
- The cold butter in the biscuit dough creates layers as it melts during baking, resulting in fluffy biscuits that perfectly complement the creamy filling.
Frequently Asked Questions About Chicken Pot Pie Casserole
Yes, rotisserie chicken is a great alternative. It saves time and adds flavor that enhances the overall dish, making your preparation even quicker.
The filling should be thick and bubbly when it is transferred to the baking dish. Additionally, a simmer of around 15 minutes helps meld the flavors and ensures the chicken is evenly heated.
Absolutely! You can prepare the filling and biscuits ahead of time, store them separately in the fridge, and assemble before baking. For reheating, bake at 350 degrees F until warmed through, usually around 25 minutes.
If the biscuits don’t rise, it could be due to old baking powder. Always check the expiration date on your ingredients, and avoid overmixing the dough, as this can also hinder the rise.
This dish is hearty enough to be a stand-alone meal. However, a simple green salad or steamed vegetables make a nice light side to balance the richness of the pot pie.
