Chicken Pot Pie Recipe 13×9 Pan: Sheet Pan Comfort Without the Fuss

There’s something deeply satisfying about a golden chicken pot pie straight from the oven, especially when it bakes in a single 13×9 pan.

This sheet pan version delivers all the classic comfort without the fuss of individual ramekins. The flaky crust bakes evenly over the creamy filling, packed with tender chicken and vegetables.

What makes this recipe special is its simplicity—no rolling pins or complicated techniques. Just mix, layer, and bake for a meal that feels like a warm hug on a chilly evening.

You’ll love how it transforms basic ingredients into a dish that tastes like it took hours, when really it comes together in under an hour.

Ingredients for Chicken Pot Pie Recipe 13×9 Pan

A handful of pantry staples and fresh ingredients create this comforting classic effortlessly.

The chicken breast should be fresh, ideally from a trusted butcher or Whole Foods for quality assurance. For the puff pastry, Pepperidge Farm is a reliable brand available at most supermarkets—just ensure it’s fully thawed before use. Diced vegetables should be uniform in size (about 1/4-inch pieces) for even cooking. If using fresh instead of frozen, opt for vibrant color and firm texture.

No cream of chicken soup? Cream of mushroom works as a substitute, or make a roux with butter, flour, and broth. For a richer flavor, add a splash of heavy cream to the filling. If puff pastry isn’t available, pie crust or even biscuit dough can top this dish—just adjust baking time. The thyme can be swapped for poultry seasoning at the same amount.

Assemble just before baking for the best texture. Leftovers keep in the fridge for 3-4 days and reheat beautifully in the oven. For make-ahead convenience, prep the filling a day in advance and store it separately—add the pastry topping right before baking to keep it flaky.

Step-by-Step Instructions for Chicken Pot Pie 13×9 Pan

This method delivers rich, creamy filling and golden pastry with minimal effort.

Step 1: Sauté Aromatics and Cook Chicken

Heat a large skillet over medium heat. Add the 1 whole onion and cook for 3-4 minutes until softened and translucent. Add the 2 cloves garlic cloves and cook for 30 seconds until fragrant, stirring constantly to prevent burning.

Increase heat to medium-high and add the 2 lb chicken breast pieces. Sauté for 6-8 minutes until the chicken is no longer pink and just cooked through. You’ll see the pieces turn opaque and the juices run clear.

Season with 1 tsp salt, 0.5 tsp black pepper, and 1 tsp dried thyme. This builds the flavor foundation for your filling. Remove from heat and set aside.

Step 2: Create the Creamy Filling Base

In the same skillet, melt the 0.5 cup unsalted butter over medium heat. Whisk in the 1 cup all-purpose flour to create a roux. Cook for 1-2 minutes until the mixture turns a light golden color—this removes the raw flour taste.

Gradually whisk in the 1.5 cups chicken broth and 0.5 cup whole milk until smooth. Add the 2 cans cream of chicken soup and stir to combine. The mixture should thicken to a gravy-like consistency as it comes to a gentle simmer.

Return the chicken to the skillet and add the 3 cups frozen mixed vegetables. Stir well and cook for 3-4 minutes until the vegetables are thawed and the filling is bubbly. Remove from heat and let cool slightly while you prepare the pastry.

Step 3: Assemble and Bake the Pot Pie

Preheat your oven to 375°F. Pour the chicken and vegetable filling into a 13×9-inch baking dish, spreading it evenly. The filling should be thick enough to hold its shape but still pourable.

Unfold the 1 sheet puff pastry sheet and place it over the filling, tucking the edges down inside the dish. Cut several small slits in the top to allow steam to escape during baking—this prevents a soggy crust.

Whisk the 1 whole egg with 1 tablespoon water and brush it evenly over the puff pastry. This egg wash ensures a beautiful, deep golden-brown finish. Bake for 30-35 minutes until the crust is puffed and golden brown.

Step 4: Rest and Serve

Remove from the oven and let the pot pie rest for 10 minutes before serving. This allows the filling to set slightly, making it easier to serve neat portions. The crust should be flaky and golden, with a rich, creamy filling beneath.

Use a sharp knife or pizza cutter to divide into squares. Each serving should have a generous portion of filling with a crisp, buttery crust on top. The filling will be thick and hearty, with tender chicken and vegetables in every bite.
