Ingredients

  • 4 cups cooked chicken, shredded
  • 1 cup frozen peas and carrots
  • 1 cup frozen corn
  • 1 cup diced potatoes (small dice)
  • 1/2 cup onion, chopped
  • 2 cloves garlic, minced
  • 1/4 cup all-purpose flour
  • 2 cups chicken broth
  • 1 cup milk (whole or 2%)
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • Salt and black pepper, to taste
  • 1 package refrigerated pie crusts (2 crusts)
  • 1 egg, beaten (for egg wash)
  • Nonstick spray or butter, for greasing the baking dish

Instructions

  1. Preheat your oven to 425°F (220°C). Lightly grease a 9×13-inch baking dish with nonstick spray or butter.
  2. In a large skillet over medium heat, sauté the chopped onion in a bit of oil or butter for 2–3 minutes, until it begins to soften.
  3. Add the minced garlic and cook for another 30–60 seconds, stirring often, just until fragrant.
  4. Sprinkle the flour over the onion and garlic. Cook, stirring constantly, for about 1 minute to remove the raw flour taste.
  5. Slowly whisk in the chicken broth, breaking up any lumps. Add the milk and continue whisking until the mixture is smooth.
  6. Bring the mixture to a gentle simmer and cook for about 5 minutes, stirring occasionally, until thickened into a creamy sauce.
  7. Stir in the shredded chicken, frozen peas and carrots, frozen corn, and diced potatoes. Add the dried thyme, dried rosemary, salt, and black pepper. Taste and adjust seasoning as needed, then remove from heat.
  8. Roll out one of the refrigerated pie crusts and fit it into the bottom of the prepared 9×13-inch baking dish, pressing gently to cover the base and corners. Trim excess if needed.
  9. Pour the warm chicken and vegetable filling evenly over the bottom crust, smoothing the top with a spatula.
  10. Roll out the second pie crust and place it over the filling. Pinch or crimp the edges to seal the top and bottom crusts together.
  11. Use a sharp knife to cut several small slits in the top crust to allow steam to escape while baking.
  12. Brush the top crust evenly with the beaten egg for a shiny, golden finish.
  13. Place the casserole on the middle rack and bake for 30–35 minutes, or until the crust is deep golden brown and the filling is bubbling around the edges.
  14. Remove from the oven and let the casserole rest for 10–15 minutes before slicing and serving. This helps the filling set and makes cleaner slices.

Variation

  1. Swap the chicken for leftover turkey to turn this into a Thanksgiving-leftover pot pie casserole.
  2. Use puff pastry instead of refrigerated pie crusts for an extra flaky, bakery-style top.
  3. Make it extra veggie-packed by adding sautéed mushrooms, celery, or green beans to the filling, adjusting seasoning as needed.

Cooking Notes

  1. For even cooking, dice the potatoes small and uniform, about 1/2-inch cubes, so they cook through in the oven.
  2. If you prefer softer vegetables, briefly steam or microwave the diced potatoes for 3–4 minutes before adding them to the filling.
  3. Place the baking dish on a rimmed sheet pan to catch any potential drips if the filling bubbles vigorously.

Serving Suggestions

  1. Serve with a simple green salad or steamed green beans to balance the richness of the casserole.
  2. Pair with cranberry sauce or a bright, tangy coleslaw for a sweet-tart contrast.
  3. Finish the meal with a light dessert like fresh fruit or lemon sorbet to keep things from feeling too heavy.

Tips

  • Keep the pie crusts chilled until just before using; cold dough bakes up flakier and holds its shape better.
  • Taste the sauce before adding it to the crust and adjust salt, pepper, and herbs so the flavors are spot-on.
  • If the crust is browning too quickly, loosely tent the dish with foil for the last 10 minutes of baking.

Frequently Asked Questions

  1. Can I make this chicken pot pie casserole ahead of time?
    Yes. Assemble the casserole up to the point of adding the egg wash, cover tightly, and refrigerate for up to 24 hours. When ready to bake, brush with egg, add a few extra minutes of bake time, and bake until bubbly and golden.
  2. Can I freeze this recipe?
    Yes. You can freeze it unbaked (wrapped well in plastic and foil) for up to 2–3 months. Bake from frozen at 375°F (190°C), tented with foil, for about 45–55 minutes, then uncover and bake until the crust is golden and the filling is hot.
  3. What can I use instead of refrigerated pie crusts?
    You can use puff pastry, homemade pie dough, or even a biscuit topping. Adjust bake time as needed so your chosen topping cooks through and turns golden.
  4. How do I know when the casserole is done?
    The top crust should be deep golden brown, and you should see the filling actively bubbling around the edges. An instant-read thermometer inserted into the center should read at least 165°F (74°C).

Conclusion

This Chicken Pot Pie Casserole wraps all the nostalgic comfort of classic pot pie into a fuss-free family bake. With a creamy, herb-scented filling and a golden, flaky crust, it’s the kind of cozy dinner everyone looks forward to. Serve it straight from the oven for an easy, crowd-pleasing meal any night of the week.

Notes

  • Use low-sodium chicken broth so you can better control the salt level in the final dish.
  • If your filling seems too thick, splash in a bit more broth or milk; if it’s too thin, simmer a few extra minutes before adding the vegetables and chicken.
  • Let the casserole rest before serving this is key for a nicely set, scoopable filling.
  • You can use rotisserie chicken to save time and add extra flavor.
