Easy Homemade Chicken Pot Pie Casserole transforms the classic comfort food into a simple, hearty bake with creamy chicken and vegetables topped with golden biscuit or puff pastry. It’s family-friendly, satisfying, and perfect for weeknight dinners.

Ingredients

  • 3 cups cooked chicken breast or rotisserie chicken, shredded or chopped
  • 2 cups frozen mixed vegetables (peas, carrots, corn, green beans)
  • 1/4 cup butter
  • 1/4 cup all-purpose flour
  • 2 cups chicken broth
  • 1 cup milk or half-and-half
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • Salt and black pepper, to taste
  • 1/2 teaspoon dried thyme or poultry seasoning (optional)
  • 1 can refrigerated biscuit dough or 1 sheet puff pastry

Instructions

  1. Preheat oven to 400°F (200°C). Grease a 9×13-inch baking dish.
  2. In a large skillet, melt butter over medium heat. Add onion and garlic; sauté until soft and fragrant.
  3. Whisk in flour and cook for 1 minute to form a roux.
  4. Gradually add chicken broth and milk, whisking until smooth and thickened.
  5. Stir in chicken, frozen vegetables, salt, pepper, and herbs. Simmer until heated through.
  6. Pour filling into the baking dish and spread evenly.
  7. Top with biscuit dough or puff pastry. Brush with melted butter or egg wash if desired.
  8. Bake for 25–30 minutes, or until topping is golden and filling is bubbling.
  9. Let rest for a few minutes before serving.

Notes

  • Use turkey instead of chicken for a post-holiday version.
  • Add mushrooms or celery for more flavor and texture.
  • Brush topping with butter or egg wash for a golden finish.
  • Top with mashed potatoes for a shepherd’s pie twist.
