Chicken Pot Pie Casserole Ingredients
For the Filling
• Medium Yellow Onion – Aromatic base for flavor; can substitute with shallots for a slightly sweeter taste.
• Medium Carrots (3) – Adds sweetness and vibrant color; parsnips can be a tasty variation.
• Medium Stalks Celery (3) – Provides a crunchy texture and fresh aroma; use green bell pepper as an alternative.
• Cloves Garlic (2) – Boosts flavor richness; in a pinch, garlic powder can be used instead.
• Fresh Thyme (about 10 sprigs) or Dried Thyme (1 tsp) – Infuses the casserole with herbal notes; oregano or rosemary work as good substitutes.
• Unsalted Butter (6 tbsp total, divided) – Adds depth and richness to the sauce; olive oil can be used for a non-dairy option.
• Kosher Salt – Enhances the overall flavors; sea salt is an excellent alternative.
• Freshly Ground Black Pepper – Adds warmth and complexity; consider white pepper for a milder flavor.
• All-Purpose Flour (¼ cup) – Essential for thickening the sauce; a gluten-free flour blend can be used for a gluten-free option.
• Low-Sodium Chicken Broth (2 cups or 1 14.5-ounce can) – Forms the sauce’s liquid base; vegetable broth is suitable for a vegetarian version.
• Whole or 2% Milk (1 cup) – Contributes creaminess; a non-dairy milk option is great for those avoiding lactose.
• Cooked Boneless Chicken (about 4 cups) – Provides hearty protein; rotisserie chicken is incredibly convenient, or swap with turkey for variety.
• Frozen Peas (1 cup) – Offers a sweet burst; no need to thaw, and corn or green beans can also work well.
For the Topping
• Refrigerated Jumbo or Grand-Size Biscuits (about 16 ounces) – The perfect topping for the casserole; homemade biscuit dough can lend a scratch-cooked touch.
Step‑by‑Step Instructions for Chicken Pot Pie Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C) and adjusting the rack to the middle position. This step is crucial as it ensures even cooking of your Chicken Pot Pie Casserole. While the oven is heating up, gather your ingredients and equipment, including a large skillet and a 9×13-inch baking dish.
Step 2: Prepare the Vegetables
Next, dice the medium yellow onion and slice the carrots and celery into bite-sized pieces. Mince the garlic and chop fresh thyme leaves, discarding the stems. This medley of vegetables will create a flavorful base for your casserole, adding sweetness and aroma to the dish.
Step 3: Sauté the Vegetables
In a large skillet, melt 4 tablespoons of unsalted butter over medium-high heat. Add the diced onion, sliced carrots, celery, minced garlic, thyme, kosher salt, and freshly ground black pepper. Sauté the vegetables for about 5-7 minutes, stirring occasionally, until they become tender and the onions are translucent, releasing their aromatic fragrance.
Step 4: Make the Roux
Sprinkle the all-purpose flour over the sautéed vegetables and stir well, cooking for about 1 minute. This will help create a thickened sauce for your Chicken Pot Pie Casserole. Gradually whisk in 2 cups of low-sodium chicken broth along with 1 cup of whole or 2% milk, scraping the skillet to deglaze and incorporate all the flavorful bits stuck to the bottom.
Step 5: Thicken the Sauce
Bring the mixture to a gentle simmer and let it cook for 4-5 minutes, stirring frequently. The sauce should thicken enough to coat the back of a spoon. Once your creamy filling is ready, gently stir in about 4 cups of cooked boneless chicken and 1 cup of frozen peas, adjusting the seasoning as necessary before transferring it to your prepared baking dish.
Step 6: Arrange the Biscuits
Open the package of refrigerated jumbo or grand-size biscuits and arrange them in a single layer over the creamy Chicken Pot Pie filling. This top layer of flaky biscuits will create a delightful contrast to the savory filling. Make sure they don’t touch, allowing them to rise beautifully while baking.
Step 7: Bake the Casserole
Place the Chicken Pot Pie Casserole in the preheated oven and bake for 20-30 minutes. Keep an eye on it, checking periodically until the biscuits are golden brown and the filling is bubbling around the edges. This will ensure your casserole is perfectly cooked and ready to serve.
Step 8: Brush with Butter
Once your casserole is done baking, remove it from the oven and melt the remaining 2 tablespoons of butter. Brush this melted butter over the tops of the biscuits for a glossy finish, enhancing their flavor and golden appearance. Serve hot and enjoy the comforting goodness of your Chicken Pot Pie Casserole!
How to Store and Freeze Chicken Pot Pie Casserole
Fridge: Store leftover Chicken Pot Pie Casserole in an airtight container for up to 4 days. Reheat gently in the oven to maintain biscuit texture.
Freezer: Freeze the casserole (without biscuits) for up to 2 months. Thaw in the fridge overnight before reheating and adding fresh biscuits on top.
Reheating: To reheat, place the casserole in a preheated oven at 350°F (175°C) for about 25-30 minutes or until warmed through. If using frozen, increase time accordingly.
Covering: Always cover with foil while reheating to prevent the biscuits from burning. This way, you’ll enjoy that comforting flavor again!
Make Ahead Options
These Chicken Pot Pie Casserole preparations are a lifesaver for busy weeknights! You can prepare the filling (vegetable mixture combined with sauce and chicken) up to 24 hours in advance. Simply let it cool, then transfer it to a covered container and refrigerate. The biscuits can remain in their packaging until you’re ready to bake. To maintain the casserole’s delicious quality, avoid adding the biscuits until just before baking to keep them flaky. When you’re ready to serve, spoon the filling into a baking dish, arrange the biscuits on top, and bake as instructed for 20-30 minutes until golden. Enjoy a heartfelt meal with minimal effort!

Chicken Pot Pie Casserole Recipe FAQs
What is the best way to choose ripe vegetables for this casserole?
Absolutely! For the freshest flavor, select vegetables that are firm and vibrant. Look for medium yellow onions that are dry and have no soft spots. Carrots should be bright orange and crisp, while celery stalks should be plump without any dark spots. Fresh thyme should be vibrant green, and aromatic, which indicates good quality.
How should I store leftovers of this Chicken Pot Pie Casserole?
For optimal freshness, store any leftovers in an airtight container for up to 4 days in the refrigerator. I recommend placing the biscuits on top to help maintain their texture. When you’re ready to enjoy a cozy meal again, reheating in the oven at 350°F (175°C) will allow the biscuits to become warm and flaky again!
Can I freeze Chicken Pot Pie Casserole, and if so, how?
Yes, you can! To freeze your Chicken Pot Pie Casserole, assemble the filling without the biscuits and transfer it into a freezer-safe container. It can be stored for up to 2 months. When you’re ready to serve, thaw it in the refrigerator overnight, and add fresh biscuits before baking according to the instructions.
What should I do if my sauce isn’t thickening properly?
Very good question! If you notice your sauce isn’t thickening as expected, it may be because the flour wasn’t mixed in completely. To troubleshoot, whisk the mixture continuously while it simmers; this helps eliminate any clumps and encourages thickening. If it remains too thin, you can mix an additional tablespoon of flour with a bit of water to create a slurry and stir it in slowly until the desired thickness is reached.
Are there any dietary considerations for this Chicken Pot Pie Casserole?
Absolutely! If you’re cooking for those with dietary restrictions, simply swap the chicken for turkey or eliminate it for a vegetarian version using vegetable broth. For lactose intolerant individuals, use non-dairy milk options and olive oil instead of butter. Always check ingredient labels for allergens, especially with biscuits and chicken broth.
Can I use homemade biscuit dough instead of store-bought?
Of course! Using homemade biscuit dough can create a fantastic, from-scratch experience. Just prepare your dough as per your favorite recipe, then layer it on top of the filling in the casserole dish. You’ll enjoy the added satisfaction of a fresh-baked biscuit topping, and it pairs beautifully with the Chicken Pot Pie Casserole!
