Step-by-Step: Chicken Pot Pie Casserole

Ready to dive into the cooking process? Follow these steps for a Chicken Pot Pie Casserole that will impress everyone at the table.
Step 1: Sauté the Vegetables
In a large skillet, melt 4 tablespoons of the unsalted butter over medium heat. Add the diced onion, carrots, and celery. Sauté for about 5 to 7 minutes, or until the vegetables are tender.
Step 2: Add Seasonings
Stir in the dried thyme, kosher salt, black pepper, onion powder, and minced garlic. Cook for an additional 1 to 2 minutes until the garlic is fragrant.
Step 3: Make the Sauce
Sprinkle the flour over the sautéed vegetables and stir to combine. Gradually pour in the chicken broth and milk, whisking continuously to prevent lumps. Bring the mixture to a simmer and let it thicken, about 3 to 4 minutes.
Step 4: Combine the Filling
Once the sauce has thickened, stir in the shredded chicken, frozen peas, and corn kernels. Mix well until everything is evenly coated in the creamy sauce. Remove from heat.
Step 5: Prepare the Casserole Dish
Preheat your oven to 375°F (190°C). Grease a 9×13-inch oven-safe casserole dish with the remaining 2 tablespoons of butter. Pour the chicken mixture into the dish, spreading it out evenly.
Step 6: Top with Biscuits
Separate the refrigerated biscuits and arrange them on top of the chicken filling. You can leave some space between them for a nice golden rise.
Step 7: Bake
Bake the casserole in the preheated oven for about 25 to 30 minutes or until the biscuits are golden brown and cooked through. If the biscuits brown too quickly, cover the dish loosely with foil.
Step 8: Serve & Enjoy!
Once baked, let the casserole cool for a few minutes before serving. Dish it out, and enjoy the warm, comforting flavors of your Chicken Pot Pie Casserole!
Quick Replacement Ideas
If you’re missing an ingredient or want to make some substitutions, here are a few quick ideas:
- Use chicken thighs instead of chicken breast for a richer flavor.
- Swap out frozen mixed vegetables for the peas and corn for added variety.
- Replace butter with olive oil for a dairy-free option.
- Try whole wheat flour instead of all-purpose flour for a healthier twist.
Pro Tips & Notes

- You can use rotisserie chicken for a quicker option—just shred and toss it in!
- Feel free to add herbs like parsley or rosemary for extra flavor.
- This casserole can be made ahead of time and stored in the refrigerator before baking.
