Ultimate Creamy Chicken Pot Pie Casserole
Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- Heat olive oil in a large skillet or Dutch oven over medium-high heat. Add the cubed chicken and cook until browned on all sides, about 5-7 minutes. Remove chicken from the skillet and set aside.
- Add the diced onion, carrots, and celery to the same skillet. Cook over medium heat, stirring occasionally, until vegetables are slightly softened, about 5-8 minutes. Stir in the dried thyme and rosemary for 1 minute until fragrant.
- Add butter to the skillet and let it melt. Once melted, sprinkle in the all-purpose flour. Cook, stirring constantly, for 1-2 minutes to create a roux.
- Gradually whisk in the chicken broth and whole milk, stirring constantly to prevent lumps. Bring the mixture to a gentle simmer, stirring until it thickens, about 3-5 minutes.
- Remove from heat. Stir in the cooked chicken, thawed peas, and corn. If using, stir in the heavy cream. Season with salt and pepper to taste. Pour the filling into the prepared baking dish.
- In a large mixing bowl, whisk together the flour, baking powder, and salt.
- Add the cold, cubed butter to the flour mixture. Use a pastry blender, two knives, or your fingertips to cut the butter into the flour until the mixture resembles coarse crumbs.
- Make a well in the center and pour in the buttermilk. Mix with a spoon or your hands until just combined and a shaggy dough forms. Be careful not to overmix.
- Drop spoonfuls of the biscuit dough evenly over the chicken filling in the baking dish. You can flatten them slightly, or leave them as rustic dollops.
- (Optional egg wash): In a small bowl, whisk the egg and water. Lightly brush the tops of the biscuits with the egg wash for a golden sheen.
- Bake for 30-35 minutes, or until the biscuit topping is golden brown and cooked through, and the filling is bubbly. If the topping browns too quickly, you can loosely cover it with foil.
- Let the casserole rest for 5-10 minutes before serving.
Notes
Pro Tips for Making This chicken pot pie casserole
Over the years, from countless kitchen experiments and more than a few happy accidents, I’ve gathered some wisdom that I love to share. When it comes to our chicken pot pie casserole, a few thoughtful touches can elevate it from wonderful to absolutely unforgettable.
My Secret Trick: I always make sure to properly brown the chicken breasts before adding the vegetables. This simple step creates a layer of rich, savory flavor at the bottom of your pot, called a “fond,” which then deglazes into your sauce, adding incredible depth to your
chicken pot pie casserole. It’s a game-changer!For the biscuit topping, remember that cold butter is your best friend. Just like with pie crusts, tiny pieces of cold butter create pockets of steam during baking, leading to an incredibly tender and flaky biscuit topping that’s simply divine. Don’t overmix the dough!
Don’t be shy with your herbs! While dried thyme and rosemary are lovely, if you have fresh on hand, a little sprinkle at the end of cooking the filling can brighten all those comforting flavors beautifully. It’s a touch my grandmother always appreciated.
Allow your filling to cool slightly before topping with the biscuit dough. This helps prevent the biscuits from sinking into the hot liquid and ensures they bake up perfectly light and airy on top of your
chicken pot pie casserole.
Fun Variations for chicken pot pie casserole
One of the greatest joys of home baking is making a recipe truly your own, isn’t it? This chicken pot pie casserole is wonderfully adaptable, inviting all sorts of creative twists. My sister, for instance, adores a touch of extra spice, while a friend loves when I sneak in some unexpected vegetables!
Veggie Twists
Feel free to get creative with your vegetables! I often add diced sweet potatoes for a touch of sweetness and color, or even some sliced mushrooms for an earthy depth. Fresh green beans, snipped into bite-sized pieces, also make a lovely addition to this hearty chicken pot pie casserole.
Cheesy Delights
For an extra layer of richness, try stirring in a handful of shredded cheddar or Gruyère cheese into the filling just before you top it with the biscuits. The cheese melts beautifully, adding a delicious tang and creaminess to your chicken pot pie casserole.
Crust Alternatives
While our biscuit topping is truly special, you can certainly experiment with other crusts. A puff pastry top, brushed with an egg wash, bakes up into a gorgeously flaky golden lid. For a lighter touch, you could even try a simple streusel topping made with flour, butter, and herbs.
What to Serve With chicken pot pie casserole
When I serve this glorious chicken pot pie casserole, I love to round out the meal with something fresh and vibrant to complement its rich, savory character. It’s like putting the perfect frame around a beautiful painting! My mom always said a balanced meal is a happy meal.
A crisp, simple green salad with a light vinaigrette is always my top choice. Its bright, fresh flavors provide a lovely counterpoint to the creamy filling of the chicken pot pie casserole. You could even add some crunchy croutons or a sprinkle of toasted nuts for extra texture.
Another wonderful pairing is a side of warm, crusty bread. It’s perfect for soaking up any extra bits of that delicious, herby sauce from your chicken pot pie casserole. And for a truly easy addition, a simple side of steamed broccoli or asparagus adds a touch of green without any fuss.

For longer storage, you can freeze individual portions for up to 2-3 months. Just make sure it’s well-wrapped to prevent freezer burn.
Reheating with Love
When you’re ready to enjoy it again, reheat the chicken pot pie casserole in the oven at 300°F (150°C) until warmed through, usually about 20-30 minutes, covering it loosely with foil if the biscuits start to get too dark. My personal tip? A little sprinkle of fresh parsley or chives after reheating brings a lovely touch of freshness back to life.
