Ingredients
  

For the Chicken Filling
  • 2 cups cooked chicken, shredded or diced
  • 1 tablespoon olive oil
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 cup carrots, diced
  • 1 cup frozen peas
  • 1/2 cup corn kernels
For the Creamy Sauce
  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour
  • 2 cups chicken broth
  • 1 cup milk
  • 1/2 cup heavy cream
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon dried thyme
For the Topping
  • 1 sheet puff pastry (thawed) or biscuit dough
  • 1 egg (for egg wash)

Method
 

  1. Heat oil and sauté onions, garlic, and vegetables until softened, ensuring they release flavor and cook evenly before baking.
  2. Prepare a roux with butter and flour, then gradually whisk in broth and milk to create a smooth, thick sauce.
  3. Combine cooked chicken and vegetables with the sauce, allowing everything to simmer briefly for flavor blending.
  4. Transfer the mixture into a baking dish and cover with pastry or biscuit topping, ensuring even coverage.
  5. Bake until the top is golden and the filling is bubbling, indicating the casserole is fully cooked.
  6. Allow the dish to rest before serving so the sauce thickens and holds its structure when plated.

Notes

  • Properly cooking the roux prevents a raw flour taste and ensures a creamy, professional-quality sauce.
  • Gradually adding liquid while whisking helps avoid lumps and keeps the texture smooth.
  • Venting the pastry allows steam to escape, keeping the topping crisp rather than soggy.
  • Resting the casserole before serving improves texture and makes portioning easier.
