Creamy Chicken and Vegetable Pot Pie Bake
Tender chicken, mixed vegetables, and a creamy sauce bake beneath a golden crescent-roll topping in this chicken pot pie casserole. It has the familiar flavors of pot pie without a bottom crust or pastry to roll out. Cooked chicken and frozen vegetables keep the preparation manageable, while a short rest after baking gives the filling time to settle before serving.
The main thing to watch is the topping. Crescent dough needs enough oven time to cook through where it meets the filling, so the chicken mixture goes into the baking dish hot. That gives the dough a better chance to brown on top without staying soft underneath.
Ingredients
Yield: About 6 servings
Prep time: About 20 minutes
Bake time: 25 to 35 minutes
Total time: About 1 hour, including resting
- 3 tablespoons (42 g) unsalted butter
- 1 medium yellow onion, diced, about 1 cup (150 g)
- 1/3 cup (40 g) all-purpose flour
- 1 3/4 cups (415 ml) low-sodium chicken broth
- 3/4 cup (180 ml) whole milk
- 1/2 teaspoon dried thyme
- 1/2 teaspoon kosher salt, plus more to taste
- 1/4 teaspoon freshly ground black pepper
- 3 cups (about 420 g) cooked chicken, diced or shredded
- 3 cups (about 400 g) frozen mixed vegetables, such as peas, carrots, corn, and green beans
- 1 can (8 ounces/226 g) refrigerated crescent-roll dough
The salt amount is a starting point. Broths and cooked chicken vary, so taste the filling before adding the dough. If the chicken was heavily seasoned or the broth is full-sodium, you may need less.
A 9-by-13-inch (23-by-33-cm) baking dish gives the filling room to heat evenly and leaves a broad surface for the topping. A slightly smaller dish can work, but a deeper layer of filling may require more baking time.
How to make the pot pie bake
Heat the oven and prepare the dish. Set the oven to 375°F (190°C). Lightly grease a 9-by-13-inch baking dish.
Cook the onion. Melt the butter in a large skillet or saucepan over medium heat. Add the onion and cook, stirring occasionally, until softened, about 5 minutes. It does not need to brown.
Make the sauce. Sprinkle the flour over the onion and stir for about 1 minute. Gradually pour in the chicken broth, stirring or whisking as you go to break up lumps. Add the milk, thyme, salt, and pepper. Bring the mixture to a gentle simmer and cook, stirring often, until it thickens enough to coat a spoon, about 3 to 5 minutes.
Add the chicken and vegetables. Stir in the cooked chicken and frozen mixed vegetables. Cook for another 2 to 3 minutes, until the vegetables have thawed and the filling is hot. Taste and adjust the seasoning. The sauce should be creamy and spoonable, since it will thicken further as the casserole rests.
Fill the dish and add the topping. Spread the hot chicken mixture in the prepared baking dish. Unroll the crescent dough and arrange it over the filling. Press the perforations together gently if you want a more continuous crust. Leave a few small gaps near the edges so steam can escape.
Bake. Bake for 25 to 35 minutes, until the topping is deeply golden and cooked through, including the areas near the center. If the top browns before the dough underneath is done, loosely cover the dish with foil and continue baking.
Rest before serving. Let the casserole stand for 10 minutes. The filling will be very hot when it comes out of the oven, and resting makes it easier to spoon onto plates.
Getting the filling and topping right
The sauce should look a little looser in the skillet than you want it to look on the plate. Flour thickens the broth and milk as they simmer, and the filling firms up more during the rest after baking. If it becomes stiff before it goes into the dish, stir in a splash of broth. If it still looks watery after several minutes at a simmer, cook it a little longer while stirring.
Frozen mixed vegetables can go straight into the skillet. Heating them in the sauce before assembly prevents a cold center from slowing the bake. There is no need to cook them until soft; they will spend more time in the oven. For a mix with large pieces of green beans or carrots, check that the vegetables are tender when the casserole is done.
The crescent topping is easiest to handle while cold. Open the can just before you need it, then lay the dough over the hot filling without stretching it thin. A few seams or uncovered spots are fine. They let steam out and make it easier to see whether the filling is bubbling. Because brands and oven temperatures vary, judge doneness by the dough rather than the clock alone. The center should look baked, not pale or wet where the dough touches the sauce.
Cooked chicken is the practical choice here. Leftover roasted chicken, poached chicken, or a store-bought rotisserie chicken will all work. Remove the skin and bones, then cut or shred the meat into bite-size pieces. If using freshly cooked chicken, make sure it is fully cooked before adding it to the filling; the oven time for this casserole is intended to bake the topping and heat the assembled dish, not cook raw poultry.
Serving and storing leftovers
This creamy chicken and vegetable bake is a full meal on its own. A simple green salad or sliced fruit works well alongside it if you want something fresh. Spoon servings out rather than trying to cut neat squares: the filling is meant to be creamy, and the crescent topping will break into pieces as you serve it.
Refrigerate leftovers in a covered container within 2 hours of cooking and use them within 3 to 4 days. Reheat individual portions until hot throughout. The microwave is convenient, though it softens the topping. For a firmer top, warm leftovers in an oven-safe dish at 350°F (175°C), loosely covered until the filling is hot, then uncover briefly. Reheated leftovers should reach 165°F (74°C).
For the best texture, bake the casserole shortly before serving. The filling can be made ahead and refrigerated separately, but reheat it until hot before adding the crescent dough and baking. Putting cold filling under the dough can leave the underside underbaked while the top turns brown.
A warm casserole without the extra pastry work
A good pot pie bake depends on a well-seasoned filling and a topping that has time to cook all the way through. Starting with hot chicken and vegetables takes care of much of that work before the dish reaches the oven. Once the crescent dough is golden, give the casserole its brief rest, then serve it warm while the filling is creamy and the top still has a little crispness.
