Ingredients
For the Filling
- 3 cups cooked shredded or diced chicken
- 1 tablespoon butter
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 2 cups frozen mixed vegetables
- 1 can (10.5 ounces) cream of chicken soup
- 1 cup chicken broth
- 1/2 cup whole milk
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried thyme
- 1/2 teaspoon dried parsley
- 1/4 teaspoon garlic powder
For the Topping
- 1 tube refrigerated biscuit dough
- 2 tablespoons melted butter
- 1/2 teaspoon dried parsley
- Pinch of garlic powder
Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9 x 13-inch baking dish and set it aside.
2. Sauté the Aromatics
Melt the butter in a large skillet over medium heat.
Add the chopped onion and cook for about 3–4 minutes, until softened.
Add the minced garlic and cook for another 30 seconds, just until fragrant.
3. Make the Creamy Filling
Add the cream of chicken soup, chicken broth, and milk to the skillet.
Stir until smooth and creamy.
Add the salt, black pepper, thyme, parsley, and garlic powder.
Cook for 2–3 minutes, stirring occasionally, until the sauce is heated through and slightly thickened.
4. Add the Chicken and Vegetables
Stir in the cooked chicken and frozen mixed vegetables.
Cook for another 2–3 minutes, just until everything is evenly combined.
There’s no need to thaw the vegetables first.
5. Transfer to the Baking Dish
Pour the creamy chicken mixture into the prepared baking dish.
Spread it into an even layer.
6. Add the Biscuit Topping
Arrange the refrigerated biscuit dough evenly over the top of the chicken mixture.
Leave a little space between the biscuits so steam can escape and the biscuits can brown properly.
7. Bake
Place the casserole in the preheated oven and bake for approximately 25–30 minutes, or until the biscuits are puffed and golden brown and the filling is bubbling around the edges.
If the biscuits begin browning too quickly while the center still needs time, loosely cover the top with aluminum foil.
8. Add the Finishing Butter
Mix the melted butter with dried parsley and a pinch of garlic powder.
Brush the mixture over the hot biscuits as soon as the casserole comes out of the oven.
Let the casserole rest for about 5–10 minutes before serving.
Tips for the Best Chicken Pot Pie Casserole
Use cooked chicken: Rotisserie chicken is an excellent shortcut and adds plenty of flavor.
Don’t overcook the vegetables: Frozen mixed vegetables can go directly into the filling. They’ll finish cooking in the oven.
Give the biscuits room: Avoid packing the biscuit dough tightly together. Space between the biscuits allows heat to circulate and helps them cook evenly.
Let it rest: The filling will be very hot and loose immediately after baking. A short resting period allows the creamy sauce to thicken.
Check the biscuits: Different brands and sizes of refrigerated biscuits can require slightly different baking times.
Easy Variations
Use Leftover Turkey
Replace the chicken with leftover cooked turkey for an easy post-holiday casserole.
Add More Vegetables
Try adding mushrooms, corn, green beans, diced potatoes, carrots, or celery.
Make It Cheesy
Stir 1 cup of shredded cheddar cheese into the chicken filling before transferring it to the baking dish.
Add More Herbs
Fresh thyme, rosemary, parsley, or sage can give the casserole an even more homemade flavor.
Use Puff Pastry
For a more traditional pot-pie-style topping, replace the biscuits with puff pastry. Cut a few small vents in the pastry before baking.
What to Serve With Chicken Pot Pie Casserole
This casserole is already a complete and filling meal, but you can serve it with:
- Simple green salad
- Steamed broccoli
- Roasted vegetables
- Cranberry sauce
- Dinner rolls
- Fresh fruit
A crisp green salad is especially nice alongside the creamy filling.
Storage and Reheating
Store leftover casserole in an airtight container or cover the baking dish tightly and refrigerate for up to 3–4 days.
Reheat individual portions in the microwave until thoroughly hot.
For a larger portion, cover with foil and warm in a 350°F (175°C) oven until heated through.
The biscuit topping is best when reheated in the oven or air fryer because it helps restore some of its crispness.
Final Thoughts
This Chicken Pot Pie Casserole delivers all the comforting flavors of classic chicken pot pie in a much easier format. Tender chicken, creamy gravy, colorful vegetables, and golden biscuits come together in one satisfying dish that’s perfect for feeding the whole family.
