Ingredients You’ll Need
Rotisserie chicken makes this one fast, though any cooked, shredded chicken works. Refrigerated pie crust or biscuit dough both work for the topping – pie crust gives a flakier, more traditional finish, while biscuits give a softer, more rustic top.
Ingredients
3 tbsp butter
1 small onion, diced
2 carrots, diced
2 celery stalks, diced
3 tbsp all-purpose flour
2 cups chicken broth
1/2 cup milk
3 cups cooked chicken, shredded
1 cup frozen peas
1/2 tsp dried thyme
1 refrigerated pie crust or 1 tube refrigerated biscuits
1 egg, beaten, for egg wash
Salt and pepper, to taste

Directions
- Preheat your oven to 400°F.
Melt the butter in a large oven-safe skillet or saucepan over medium heat.
Add the onion, carrots, and celery and cook for 6 to 7 minutes, until softened. - Sprinkle the flour over the vegetables and stir constantly for about a minute to cook off the raw flour taste.
Slowly whisk in the chicken broth and milk, continuing to whisk until the sauce thickens, about 4 to 5 minutes.
Stir in the shredded chicken, peas, and thyme. - Season the filling with salt and pepper.
If using a skillet that isn’t oven-safe, transfer the filling to a greased 9-inch pie dish or 8×8-inch baking dish.
This one takes a bit of timing, just so you know, since the filling needs to be hot before the topping goes on. - Roll the pie crust out slightly and lay it over the filling, tucking or crimping the edges, and cut a few small slits for steam to escape.
If using biscuits, arrange them in a single layer over the top of the filling instead.
Brush the crust or biscuits with the beaten egg wash.
- Bake for 20 to 25 minutes, until the topping is golden brown and the filling is bubbling around the edges.
Let it rest for 5 minutes before serving.
Serve hot and enjoy!
Important Recipe Notes
- Cook the roux and broth together until properly thickened. A thin filling will bubble up and make the topping soggy. The sauce should coat the back of a spoon before you add the chicken and vegetables.
- Cut slits in a pie crust topping. This lets steam escape as it bakes, which keeps the crust from getting soggy or puffing up unevenly.
- Rotisserie chicken is the fastest option here, but any leftover cooked chicken breast or thigh meat works just as well.

- Biscuits give a softer, more rustic top, while pie crust gives a flakier, more traditional finish – either one works well, so use whichever you have on hand.
- Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F for the best texture, since the microwave can make the topping soggy.
- This doesn’t freeze particularly well with the topping already baked on, though the filling alone freezes fine for up to 3 months if you want to top it fresh later.
How to Serve, Store & Customize This Recipe
Serving:
Serve hot straight from the dish, with a simple green salad on the side if you want something lighter alongside it. This is filling enough on its own to make a complete dinner.

Storage:
Keep leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F, covered loosely with foil, until warmed through.
Customization:
Add diced potatoes to the filling for extra heartiness, or swap the chicken for leftover turkey around the holidays. A pinch of poultry seasoning in the filling adds another layer of savory flavor.
