Here’s what you’ll need:
For the Savory Filling:
- ½ cup (1 stick) unsalted butter: The rich base for our roux.
- 1 large yellow onion, diced: Provides a sweet, aromatic foundation.
- 2 cloves garlic, minced: For essential depth of flavor.
- ½ cup all-purpose flour: The key thickening agent for our gravy.
- 2 cups low-sodium chicken broth: Provides the savory liquid base. Using low-sodium allows you to control the salt level.
- 1 cup whole milk or half-and-half: For creaminess and richness. For a lighter version, 2% milk can work.
- 1 teaspoon poultry seasoning: The classic blend that defines pot pie flavor.
- ½ teaspoon dried thyme: Adds an earthy, floral note.
- ½ teaspoon dried parsley:
- Salt and freshly ground black pepper to taste: Season generously.
- 4 cups cooked chicken, shredded or cubed: Rotisserie chicken is a perfect, flavorful shortcut.
- 16 oz frozen mixed vegetables (classic blend: peas, carrots, corn, green beans): Do not thaw; this ensures they don’t become mushy.
- Optional: ½ cup frozen pearl onions, ½ cup sliced mushrooms, or 1 cup diced potatoes (par-boiled).
For the Topping (Choose One):
- Option 1 (Biscuit Topping): 1 can (16.3 oz) refrigerated buttermilk biscuits (8 count). For a homemade touch, use your favorite drop biscuit recipe.
- Option 2 (Puff Pastry Topping): 1 sheet frozen puff pastry, thawed. Brush with an egg wash (1 egg + 1 tbsp water) for a golden shine.
- Option 3 (Drop Biscuit Topping): A simple batter made from 2 cups Bisquick mix, ⅔ cup milk, and ½ teaspoon garlic powder.
Finishing Touches:
- 1 egg, beaten (for egg wash on pastry): For a glossy, golden-brown finish.
- Fresh parsley, chopped, for garnish.

How to Make Chicken Pot Pie Casserole:
Now that you have your ingredients ready, let’s dive into the steps for making this delightful Chicken Pot Pie Casserole. We’ll focus on the biscuit topping method, the most popular and accessible version.
Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish. Ensure your cooked chicken is shredded and your frozen vegetables are measured and ready.
Step 2: Create the Roux
In a large Dutch oven or pot, melt the butter over medium heat. Add the diced onion and cook for 5-6 minutes until softened and translucent. Add the minced garlic and cook for one more minute until fragrant.
Step 3: Build the Gravy Base
Sprinkle the flour over the onions and garlic. Cook, stirring constantly, for about 1-2 minutes to cook out the raw flour taste. This mixture is called a roux and is the foundation of your sauce.
Step 4: Whisk in Liquids
Slowly pour in the chicken broth and milk while whisking constantly to avoid lumps. Continue to whisk until the mixture is smooth.
Step 5: Thicken the Sauce
Bring the sauce to a simmer, stirring frequently. Let it cook for 3-5 minutes, until it has thickened noticeably and can coat the back of a spoon.
Step 6: Season and Combine
Reduce the heat to low. Stir in the poultry seasoning, thyme, parsley, and a generous amount of salt and pepper. Taste and adjust seasoning—this is your chance to make the gravy perfect.
Step 7: Add Chicken and Veggies
Add the cooked chicken and the frozen mixed vegetables to the pot. Stir until everything is evenly coated in the creamy gravy. The frozen veggies will cool the mixture down, which is perfect.
Step 8: Assemble the Casserole
Pour the entire filling mixture into your prepared 9×13 inch baking dish and spread it into an even layer.
Step 9: Apply the Topping
If using canned biscuits, arrange the 8 raw biscuits evenly on top of the hot filling. They will expand and bake into a fluffy, golden blanket.
- For Puff Pastry: Unfold the thawed sheet, place it over the filling, and tuck in the edges. Cut a few slits in the top to allow steam to escape. Brush with egg wash.
- For Drop Biscuit Topping: Mix the Bisquick, milk, and garlic powder and drop spoonfuls evenly over the filling.
Step 10: Bake to Golden Perfection
Place the casserole on a baking sheet (to catch any potential bubble-overs) and bake for 25-35 minutes, or until the filling is bubbly around the edges and the biscuit topping is deeply golden brown and cooked through.
Step 11: Rest and Serve
Remove the casserole from the oven and let it stand for 10-15 minutes before serving. This allows the filling to set slightly, making it easier to scoop and serve.
Tips for Success:
- Season Aggressively: The gravy is the heart of the dish. Taste it after adding your spices and don’t be shy with the salt and pepper. The chicken and vegetables will dilute the seasoning slightly.
- Don’t Thaw the Veggies: Using frozen vegetables straight from the bag prevents them from overcooking and becoming mushy. They will heat through perfectly in the oven.
- Prevent a Soggy Bottom: Ensuring your filling is hot or very warm when you add the biscuit topping helps the bottom of the biscuits start cooking immediately, preventing sogginess.
- Check Biscuit Doneness: The top may look brown before the biscuits are fully cooked. Use a toothpick to check the center of a biscuit; it should come out clean.
- Make-Ahead: You can prepare the filling up to 2 days in advance. Store it covered in the fridge. When ready to bake, reheat the filling on the stove until warm before transferring to the dish and adding the topping. Bake as directed.

Equipment Needed:
- Large Dutch oven or heavy-bottomed pot
- 9×13 inch baking dish
- Whisk
- Cutting board and knife
- Measuring cups and spoons

Variations of Chicken Pot Pie Casserole:
- Turkey Pot Pie Casserole: The perfect way to use Thanksgiving leftovers. Substitute cooked turkey for the chicken.
- Vegetarian Pot Pie Casserole: Omit the chicken. Use vegetable broth and add more vegetables like mushrooms, par-boiled potatoes, and leeks. For protein, add a can of drained chickpeas.
- Herbaceous Version: Use fresh herbs instead of dried. Triple the amount and add them at the very end for a brighter flavor (e.g., 1 tbsp fresh thyme).
- Cheesy Twist: Stir 1 cup of shredded sharp cheddar cheese into the filling after it has thickened for an extra layer of flavor.
- From-Scratch Biscuits: Use your favorite homemade drop biscuit recipe for the topping for a truly artisanal touch.

FAQs about Chicken Pot Pie Casserole:
Q: Can I freeze chicken pot pie casserole?
A: Yes, it freezes beautifully. Assemble the casserole completely with the filling and topping. Cover tightly with plastic wrap and then foil. Freeze for up to 3 months. Bake from frozen, covered, at 375°F for about 45 minutes, then uncover and bake for another 20-30 minutes until hot and golden.
Q: Why is my filling too runny?
A: This can happen if the roux wasn’t cooked long enough or if the filling didn’t simmer long enough to thicken before baking. You can fix it by creating a slurry: mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir it into the bubbly filling on the stovetop. Cook for 1-2 minutes until thickened.
Q: Can I use fresh vegetables instead of frozen?
A: You can, but they must be pre-cooked. Fresh carrots, potatoes, and green beans should be par-boiled until just tender before adding to the filling to ensure they cook through.
Q: What’s the best chicken to use?
A: Rotisserie chicken is the ultimate shortcut, providing great flavor and moistness. You can also boil or bake your own chicken breasts or thighs. Using a mix of white and dark meat is ideal for the best flavor and texture.
Q: My biscuit topping is done but the filling isn’t bubbly. What now?
A: If the top is getting too brown but the center is still cold, loosely tent the entire casserole dish with aluminum foil. This will slow down the browning while allowing the filling to continue heating through.
