chicken pot pie casserole Ingredients
For the Casserole:
- 3 cups cooked chicken breast, diced or shredded
- 2 tablespoons butter (unsalted)
- 1 medium onion, diced
- 3 cloves garlic, minced
- 3 cups mixed frozen vegetables (carrots, peas, corn, green beans)
- 1/4 cup all-purpose flour
- 2 cups chicken broth (low sodium)
- 1 cup whole milk
- 1/2 teaspoon dried thyme
- 1/2 teaspoon dried rosemary
- 1/2 teaspoon black pepper
- 1 teaspoon salt (adjust to taste)
For the Topping:
- 2 cups biscuit baking mix (like Bisquick)
- 2/3 cup whole milk
- 1 cup shredded cheddar cheese
- 2 tablespoons fresh parsley, chopped (optional)
Instructions
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray and set aside.
Step 2: Make the Creamy Filling
In a large skillet over medium heat, melt the butter. Add the diced onion and cook for 3-4 minutes until softened. Add the minced garlic and cook for another minute until fragrant.
Step 3: Create the Sauce
Sprinkle the flour over the onion and garlic mixture, stirring constantly for about 1 minute to cook out the raw flour taste. Gradually pour in the chicken broth while whisking continuously to prevent lumps. Add the milk, thyme, rosemary, salt, and black pepper.
Step 4: Add Chicken and Vegetables
Bring the sauce to a gentle simmer and cook for 3-4 minutes until it thickens slightly. Stir in the cooked chicken and frozen vegetables. Mix everything together until well combined and heated through.
Step 5: Transfer to Baking Dish
Pour the chicken and vegetable mixture into your prepared 9×13-inch baking dish, spreading it evenly across the bottom.
Step 6: Prepare the Biscuit Topping
In a medium bowl, combine the biscuit baking mix, milk, and shredded cheddar cheese. Stir just until combined the mixture should be slightly lumpy, not smooth.
Step 7: Add Topping
Drop spoonfuls of the biscuit mixture evenly over the chicken filling. You don’t need to spread it perfectly; rustic dollops work beautifully and create a golden, textured top.
Step 8: Bake
Place the casserole in the preheated oven and bake for 30-35 minutes, or until the biscuit topping is golden brown and the filling is bubbling around the edges.
Step 9: Rest and Serve
Remove from the oven and let the casserole rest for 5 minutes before serving. Garnish with fresh parsley if desired and serve hot.

Vegetable Swaps: Feel free to use any vegetables you prefer, broccoli florets, mushrooms, or diced bell peppers all work wonderfully in this casserole.
Gluten-Free Version: Use gluten-free biscuit mix and substitute the all-purpose flour with a gluten-free flour blend or cornstarch for thickening the sauce.
Dairy-Free Alternative: Replace butter with olive oil, use unsweetened almond or oat milk, and skip the cheese or use a dairy-free alternative.
Healthier Option: Use low-fat milk, reduce the butter to 1 tablespoon, and add extra vegetables to increase the nutritional value.

FAQs About chicken pot pie casserole
Can I use raw chicken instead of cooked chicken?
Yes, but you’ll need to cook it first. Dice raw chicken breast into small pieces and cook them in the skillet with the onions until no longer pink before proceeding with the recipe.
What can I use instead of biscuit mix?
You can make a simple biscuit topping from scratch using 2 cups flour, 1 tablespoon baking powder, 1/2 teaspoon salt, 1/4 cup cold butter, and 3/4 cup milk. Mix until just combined.
Can I make this in a smaller dish?
Absolutely. Use an 8×8-inch or 9×9-inch baking dish and cut all ingredients in half for 4 servings.
Why is my biscuit topping soggy?
Make sure your filling isn’t too watery before adding the topping. The sauce should be thick enough to coat the back of a spoon. Also, ensure your oven is fully preheated.
Can I add more cheese?
Yes! Feel free to add an extra 1/2 cup of shredded cheese on top of the biscuit mixture during the last 10 minutes of baking for a cheesier crust.
How do I know when it’s done?
The biscuit topping should be golden brown, and the filling should be bubbling around the edges. You can insert a toothpick into the biscuit topping—it should come out clean.

Notes
Cooked Chicken: Rotisserie chicken is perfect for this recipe and saves time. You can also use leftover cooked chicken, turkey, or poach chicken breasts specifically for this dish.
Frozen Vegetables: No need to thaw the vegetables before adding them to the sauce. They’ll cook perfectly during the simmering and baking process.
Biscuit Topping: Don’t overmix the biscuit dough—lumps are good! Overmixing creates tough, dense biscuits instead of light and fluffy ones.
Make-Ahead: Prepare the filling up to 24 hours in advance and refrigerate. When ready to bake, make the biscuit topping fresh and add 5-10 extra minutes to the baking time if starting from cold.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or covered in a 350°F oven.
Freezing: Freeze unbaked or baked casserole for up to 3 months. Thaw overnight in the refrigerator before baking or reheating.
Thickness of Sauce: If your sauce seems too thick, add a splash more broth or milk. If too thin, simmer for a few extra minutes before adding the chicken and vegetables.
