Ingredients You’ll Need
To create this comforting Chicken Pot Pie Casserole, gather the following ingredients:
- 2 cups cooked chicken, shredded or diced (rotisserie chicken works great)
- 1 tablespoon olive oil
- 1 small onion, chopped
- 2 carrots, peeled and diced
- 2 celery stalks, diced
- 1 cup frozen peas
- 1 cup frozen corn
- ½ cup all-purpose flour
- 2 cups chicken broth
- 1 cup milk (whole or 2%)
- ½ teaspoon dried thyme
- ½ teaspoon dried rosemary, crushed
- Salt and freshly ground black pepper, to taste
- 1 (16.3 ounce) can refrigerated biscuit dough (or puff pastry, tater tots)
- Fresh parsley, chopped, for garnish (optional)

How to Make Chicken Pot Pie Casserole
Follow these simple steps to bring this comforting casserole to your table:
Step 1: Sauté Vegetables
Preheat your oven to 375°F (190°C). In a large oven-safe skillet or Dutch oven, heat the olive oil over medium heat. Add the chopped onion, carrots, and celery. Sauté for 5-7 minutes, or until the vegetables begin to soften. Add the frozen peas and corn and cook for another 2-3 minutes.
Step 2: Make the Creamy Sauce
Sprinkle the flour over the sautéed vegetables and stir constantly for 1 minute to cook out the raw flour taste. Gradually whisk in the chicken broth and milk, stirring continuously to prevent lumps. Bring the mixture to a simmer, stirring until the sauce thickens. Stir in the dried thyme, crushed rosemary, salt, and black pepper. Add the cooked chicken to the sauce and stir to combine.
Step 3: Assemble the Casserole
Pour the chicken and vegetable mixture into a 9×13 inch baking dish if you are not using an oven-safe skillet. Arrange the refrigerated biscuit dough (or puff pastry, or tater tots) over the top of the chicken mixture. If using biscuits, you can tear them into smaller pieces or leave them whole, depending on your preference.
Step 4: Bake to Golden Perfection
Bake for 20-25 minutes, or until the topping is golden brown and the filling is bubbly. If the topping starts to brown too quickly, you can loosely cover it with aluminum foil. Once baked, remove from the oven and let it rest for a few minutes before serving.
Step 5: Serve and Enjoy
Serve the Chicken Pot Pie Casserole hot, garnished with fresh chopped parsley if desired. This dish is a complete meal on its own, offering a perfect balance of protein, vegetables, and comforting flavors. Enjoy this simplified classic!

Helpful Tips for Success
- Cooked Chicken: This recipe is perfect for using up leftover roasted or rotisserie chicken. If you don’t have cooked chicken, you can quickly boil and shred chicken breasts.
- Vegetable Medley: Feel free to customize the vegetables based on what you have on hand or what your family enjoys. Green beans, mushrooms, or potatoes (diced small) can also be added.
- Topping Variations: Instead of biscuits, you can use a sheet of puff pastry, cut into squares, or even a layer of frozen tater tots for a different texture.
- Thickening the Sauce: If your sauce seems too thin, you can create a slurry with a tablespoon of cornstarch mixed with a tablespoon of cold water and whisk it into the simmering sauce until it thickens.
- Creaminess: For an extra rich sauce, you can use half-and-half or even a splash of heavy cream in addition to the milk.
- Make Ahead: You can prepare the chicken and vegetable filling ahead of time and store it in the refrigerator for up to 2 days. Assemble and bake just before serving.
