Leftover Roast Chicken Pot Pie
A spoon cracking through golden puff pastry is a fine way to deal with yesterday’s roast. This leftover roast chicken pot pie tucks generous shreds of chicken into creamy tarragon gravy with potatoes, carrots, peas, and sweetcorn. Underneath that flaky lid, the filling stays thick enough to coat the chicken instead of leaving it swimming in broth.
Why This Recipe Works
The filling and pastry do two very different jobs, and that is exactly what makes this pot pie satisfying. Tarragon, onion, garlic, and Worcestershire sauce give the creamy gravy plenty of savory character, while the potatoes and vegetables make it substantial. The puff pastry stays above the filling, where it can rise and brown instead of disappearing into the gravy.

Reheating Tip
For this pot pie, give the shredded leftover roast chicken only a brief warm-up before it reaches the oven. Put it in a skillet with a lid with a few spoonfuls of the chicken broth, cover, and warm gently over medium-low heat just until the pieces lose their refrigerator chill. The lid traps a little steam around the irregular shreds, which helps keep exposed edges from becoming unnecessarily dry.
Keep this stage short because the chicken will heat again inside the gravy as the pastry bakes. Once it feels warm and supple, move it straight into the filling.
How to Wake Up the Flavor of Leftover Roast Chicken
Tarragon is the ingredient to pay attention to here. Its fragrant, slightly anise-like character cuts through the cream and gives the roast chicken a fresh direction without burying its savory flavor. Worcestershire sauce works underneath it, bringing extra depth to the gravy.
Use a small whisk when adding the broth to the flour mixture. A smooth gravy matters because it can coat all those uneven pieces of shredded chicken rather than leaving floury pockets around them. Add the cream after the gravy has thickened, then taste before adjusting the salt and pepper. The chicken broth and Worcestershire sauce already contribute seasoning, so the final taste is the useful one.
How to Make Leftover Roast Chicken Pot Pie
Step 1: Heat the Oven
Preheat the oven to 350°F (180°C). Have a baking dish about 10 inches long ready for the filling.
Keep the puff pastry chilled while you work on the filling. Cold pastry is easier to handle and will be ready to go on once the gravy is finished.
Step 2: Soften the Onion and Garlic
Place the chopped onion in a large skillet over medium heat and cook until it softens and turns translucent. Add the crushed garlic and stir briefly until fragrant.
Keep the heat moderate. You want a soft savory base for the gravy, not deeply browned onion.
Step 3: Build the Filling
Add the diced carrots, peas, sweetcorn, cooked potatoes, tarragon, and Worcestershire sauce. Stir so the vegetables and potatoes are evenly distributed.
Sprinkle the flour over the mixture. Stir thoroughly so it coats the ingredients without collecting in dry patches.
Step 4: Make the Creamy Gravy
Pour in the chicken broth gradually while stirring or whisking. Bring the mixture to a gentle simmer and let the liquid thicken into a gravy that lightly coats a spoon.
Pour in the milk or heavy cream and stir until the color becomes evenly pale and creamy. Season with salt and black pepper to taste.
The filling should look saucy but not watery. A loose filling can make the pastry underneath damp and makes serving much messier.
Step 5: Fold In the Leftover Roast Chicken
Add the roughly shredded leftover roast chicken and fold it through the hot gravy. Keep the pieces fairly substantial; little wisps of chicken tend to vanish into a pot pie.
Stir only until the gravy reaches the chicken throughout. The oven will finish heating the filling.
Step 6: Fill the Baking Dish
Spoon the chicken mixture into the baking dish and spread it into an even layer. Leave a little room below the rim so bubbling gravy has somewhere to go besides sightseeing across your oven.
Let excessive steam escape for a moment while you prepare the pastry.
Step 7: Add the Puff Pastry Lid
Lay the defrosted puff pastry over the baking dish. Trim excess pastry where necessary, then press the edges around the rim with a fork to secure them.
Cut two small X-shaped vents in the center. These give steam a controlled exit while the pastry rises.
Brush the surface lightly and evenly with the beaten egg. Pay attention to the raised areas and edges, since those become especially attractive once browned.
Step 8: Bake Until Golden
Bake for about 40 minutes, or until the puff pastry has risen and developed a deep golden surface.
Look through the vents or around the edges for gentle bubbling from the filling. Let the pot pie settle briefly after it leaves the oven so the creamy filling is easier to spoon beneath the crisp pastry.
Conclusion
There is something especially satisfying about finding creamy chicken and vegetables beneath a pastry lid that shatters a little when the spoon goes in. Leftover roast chicken pot pie gives those roast chicken pieces plenty of rich tarragon gravy while the puff pastry brings the crisp finish. Serve it while that contrast between bubbling filling and flaky pastry is at its best.
