Quick Ingredients

3 cups cooked shredded roasted chicken (about 1 lb)
3 tbsp unsalted butter
2 tbsp olive oil (or more butter)
1 medium yellow onion, finely chopped
2 medium carrots, diced small
2 celery stalks, diced small
2 cloves garlic, minced
1 cup frozen peas
1/3 cup all-purpose flour
2 cups chicken broth (low-sodium)
1 cup whole milk or half-and-half
1 tsp kosher salt, plus more to taste
1/2 tsp freshly ground black pepper
1 tsp dried thyme or 2 tsp fresh thyme leaves
1 bay leaf (optional but encouraged)
1 sheet puff pastry (thawed) or 1 single pie crust
1 large egg + 1 tbsp water (for egg wash)

Do This

1) Preheat oven to 400°F (200°C). Butter a 9-inch deep-dish pie plate or 2-quart baking dish.
2) Sauté onion, carrot, and celery in butter and oil until softened; add garlic and peas.
3) Sprinkle in flour; cook 2 minutes. Whisk in warm broth and milk, then add salt, pepper, thyme, and bay leaf. Simmer until thick and velvety.
4) Stir in shredded roasted chicken. Taste and adjust seasoning. Transfer filling to your prepared baking dish and cool 5–10 minutes.
5) Lay puff pastry or pie crust over the filling, trim and crimp edges, and cut a few steam vents.
6) Brush pastry with egg wash. Bake 25–30 minutes until the top is deeply golden and the filling is bubbling.
7) Let rest 10–15 minutes before serving so the gravy thickens slightly and slices hold together.

Flaky sea salt, for sprinkling on the crust (optional)

Step-by-Step Instructions

Step 1: Preheat and Prep Your Dish

Set your oven rack in the center position and preheat the oven to 400°F (200°C). Lightly butter a 9-inch deep-dish pie plate or a 2-quart baking dish to prevent sticking and to help the filling bubble nicely around the edges.

Shred your cooked roasted chicken into bite-sized pieces if you have not already. Aim for a mix of white and dark meat for the best flavor and juiciness. Set aside while you prepare the gravy and vegetables.

Step 2: Sauté the Vegetables

In a large, heavy-bottomed skillet or saucepan, heat the 3 tbsp butter and 2 tbsp olive oil over medium heat until the butter melts and starts to foam.

Add the chopped onion, diced carrots, and diced celery. Cook, stirring occasionally, for 7–9 minutes, until the vegetables have softened and the onion is translucent but not browned. Adjust the heat as needed to avoid scorching.

Stir in the minced garlic and cook for 30–60 seconds, just until fragrant. Add the frozen peas and cook for another 1–2 minutes to take the chill off. The peas will finish cooking in the oven.

Step 3: Make the Roux

Sprinkle the 1/3 cup flour evenly over the vegetables. Stir well so that every bit of vegetable is coated with flour and the flour absorbs the butter and oil, forming a paste-like mixture known as a roux.

Cook this mixture over medium heat for 2 minutes, stirring constantly. This step cooks out the raw flour taste and helps develop a richer flavor in your gravy. The roux should be thick but still spreadable, with a pale golden color.

Step 4: Build the Velvety Gravy

Warm the chicken broth and milk (or half-and-half) together in a small saucepan or in the microwave until just warm; this helps prevent lumps. Slowly pour the warm broth-milk mixture into the pan with the roux, whisking constantly to maintain a smooth texture.

Add the 1 tsp kosher salt, 1/2 tsp black pepper, thyme, and bay leaf if using. Bring the mixture to a gentle simmer over medium heat, whisking frequently. As it heats, the gravy will thicken. Continue to simmer for 5–7 minutes, until the sauce is smooth, glossy, and thick enough to coat the back of a spoon.

Taste and adjust the seasoning with more salt and pepper if needed. Remember that the chicken and pastry will be relatively mild, so a well-seasoned gravy is key.

Step 5: Fold in the Shredded Chicken

Remove the bay leaf and discard it. Turn off the heat under the gravy.

Stir in the 3 cups shredded roasted chicken, folding gently until the meat is evenly distributed and well coated in the creamy vegetable gravy. The mixture should be thick but still spoonable; if it seems too thick, you can loosen it with a splash of warm broth or milk. If it is too thin, let it simmer a few more minutes, stirring often.

Transfer the filling to your prepared baking dish, smoothing the top into an even layer. Let it cool for 5–10 minutes while you prepare the pastry; this short cooling time helps keep the fat in the dough colder and encourages flakiness.

Step 6: Prepare and Place the Pastry Top

While the filling cools slightly, lightly flour your work surface. Unfold the thawed puff pastry sheet (or unroll your pie crust) onto the floured surface. If needed, use a rolling pin to gently roll it out to roughly the size and shape of your baking dish with a little extra overhang (about 1 inch).

Carefully lift the pastry and lay it over the warm filling. If using a round pie plate, trim the excess with a knife or scissors, leaving about 1/2 inch overhang, then fold and crimp it against the rim. For a rectangular or oval dish, simply trim and tuck the edges inside the dish or press them against the sides.

Using a sharp knife, cut 3–5 small slits in the top of the pastry to allow steam to escape. This keeps the crust crisp and prevents sogginess.

Step 7: Egg Wash and Bake Until Golden

In a small bowl, whisk together the egg and 1 tbsp water to make an egg wash. Brush the top of the pastry lightly but thoroughly with the egg wash, avoiding large puddles. If you like, sprinkle a pinch of flaky sea salt on top for extra flavor and a pretty finish.

Place the dish on a rimmed baking sheet to catch any bubbling overflow. Bake at 400°F (200°C) for 25–30 minutes, or until the pastry is deeply golden brown and the filling is visibly bubbling around the edges and through the steam vents.

Remove from the oven and let the chicken pot pie rest for 10–15 minutes before serving. This resting time allows the gravy to thicken slightly so the filling holds together when scooped, while still being silky and saucy.

Pro Tips

Keep the pastry cold: Cold dough equals flaky layers. Work quickly with puff pastry or pie crust, and chill it briefly if it becomes too soft while you assemble.
Use warm liquids for a smooth gravy: Adding warm broth and milk to the roux helps prevent lumps and creates that velvety, restaurant-style texture.
Season in layers: Taste the gravy after it thickens and again after adding the chicken. Well-seasoned filling is the difference between “good” and “wow.”
Do not skip the vent slits: Proper vents allow steam to escape, which keeps the crust crisp and prevents it from ballooning unevenly.
Let it rest before serving: The filling will be extremely hot right out of the oven. A short rest makes it safer to serve and improves the texture.

Variations

Herby mushroom version: Add 1 cup sliced cremini mushrooms with the onions and double the fresh thyme. Finish with a tablespoon of chopped fresh parsley or tarragon.
Cheddar-topped pot pie: Stir 1 cup shredded sharp cheddar into the hot gravy right before adding the chicken. The cheese melts into the sauce for an extra-rich, cozy filling.
Veggie-loaded option: Add 1 diced potato (parboiled until just tender) and a handful of green beans cut into 1-inch pieces. Make sure the filling remains thick; simmer a few extra minutes if needed.

Storage & Make-Ahead

To store leftovers, let the pot pie cool completely, then cover the dish tightly with foil or transfer portions to airtight containers. Refrigerate for up to 3 days. Reheat in a 350°F (175°C) oven, loosely covered, for about 20–25 minutes, removing the foil for the last 5 minutes to crisp the crust. Individual portions can also be reheated in the microwave, though the pastry will be softer.

For make-ahead, you can assemble the filling up to 2 days in advance and store it in the fridge. When ready to bake, transfer the chilled filling to your baking dish, add the chilled pastry on top, brush with egg wash, and bake, adding 5–10 extra minutes as needed until the center is hot and bubbling. Alternatively, assemble the entire pot pie, wrap tightly, and freeze unbaked for up to 2 months; bake from frozen at 400°F (200°C) for 50–60 minutes, covering with foil if the crust browns too quickly.
