Chicken pot pie is comfort food at its finest

Comfort food, to me, is a big pot full of chicken, vegetables, and a luscious cream sauce. Some baked dough or fresh bread only sweetens the deal!

You’ll find all of that and more in this easy Chicken Mushroom Pot Pie. Unlike a classic chicken pot pie, this recipe makes a few shortcuts to keep the cooking process quick and stress-free. This is what we’re doing differently:

• The pot pie is topped with store-bought phyllo dough instead of homemade pie dough. It’s an easy solution that’s crisp and buttery.
• The savory mushroom and chicken filling is made and baked in just one oven-proof skillet.
• This means you’ll only find dough on the top of the pot pie, not on the bottom.
• It’s loaded with pre-cooked chicken, mushrooms, potatoes, and the vegetables you know and love: onion, carrots, and celery.

Family dinners are made even better with this chicken and mushroom pot pie. It’s ready to eat in just 35 minutes, and can even be prepared ahead of time.

Ingredients and substitutions

You’ll find all of the classic pot pie ingredients here. What really makes it special, however, are a few secret shortcuts:

• Butter – Unsalted is best.
• Onion – An onion adds a savory, aromatic base and builds flavor in every bite of the filling.
• Carrots– Sweet and tender carrots add color, texture, and classic pot pie flavor.
• Celery– A staple in traditional pot pies, celery adds a subtle earthy flavor and a bit of crunch that balances the creamy filling.
• Mushrooms – They add another layer of meaty flavor to the pot pie. I used baby bella mushrooms, but you can use what you like.
• Potatoes – Diced Yukon Gold potatoes are extra starchy and butter. They practically melt into the pot pie filling.
• Flour – Use all-purpose flour or the gluten-free flour of your choice to help thicken the filling.
• Milk – Whole milk is necessary for the luscious cream sauce. Heavy cream works too, but only use ½ cup.
• Chicken broth – Homemade chicken broth will bring deep, savory flavors to the filling. But this is a quick pot pie, after all, so storebought is just fine!
• Fresh thyme– This fragrant herb adds warmth and depth to the filling, pairing perfectly with the chicken, mushrooms, and creamy sauce.
• Chicken – Use pre-cooked shredded chicken thighs or breasts, store-bought rotisserie chicken, or any leftover chicken you already have in the fridge. Feel free to substitute turkey or diced ham for the chicken or add them for extra protein.
• Phyllo dough – One shortcut that makes this recipe quick and easy is layering only the top with store-bought phyllo dough. If you’re up for the challenge, feel free to make your own pie dough instead or swap the phyllo for puff pastry.

How to make chicken mushroom pot pie

Thaw the phyllo dough according to the thawing instructions on the package before you get started.

While you wait for the oven to preheat and the dough to thaw, melt the butter in a cast iron skillet over medium heat on the stove. Saute the onion, carrots, and celery until soft.

Add the remaining butter, then the mushrooms. Cook until they’re tender.

Next, stir the flour, salt, and thyme in with the vegetables to make the roux and cook for a few minutes. Once the mixture thickens, slowly stir in the milk and the stock. 

Let it all simmer together while it thickens further.

To finish, stir the potatoes and shredded chicken into the thickened mixture and let it cook on the stovetop on low for 10 minutes.

Take the skillet off of the heat. Scrunch the thawed phyllo dough into bundles and tuck them into the filling. Continue until the entire filling is covered.

Gently brush the dough with melted butter, then bake in the oven until the phyllo is browned and crisp.

Let the mushroom pot pie rest for 10 minutes out of the oven. Spoon out individual portions with a large spoon, then serve and enjoy!

Customize it

There are several easy ways to customize your mushroom chicken pot pie:

• Switch up the vegetables: Use hearty root vegetables, like parsnips or turnips instead of potatoes, replace the onions with leeks, add garlic, and use fennel to bring an anise flavor to the dish. Get creative or use your favorites!
• Use frozen vegetables: Frozen peas, green beans, corn, or carrots can all be used instead of the fresh vegetables here.
• Add cheese: Stir shredded cheddar cheese, gruyere, or swiss cheese into the filling.
• Instead of shredded chicken: Use shredded turkey (this recipe would be a perfect way to use up the leftover Thanksgiving turkey), bacon, diced ham, chicken sausage, or vegetarian meat (like soy curls) instead.
• Herb it up: Simmer the filling with bay leaves and fresh parsley in addition to the fresh thyme.

Tips for Using Puff Pastry Instead of Phyllo Dough

If you’d rather use puff pastry, it makes a delicious alternative with a richer, buttery, and extra-flaky topping. Puff pastry will create more of a traditional pot pie crust, while phyllo dough gives the pie a lighter, crispier texture.

• Thaw completely first. Let the puff pastry thaw according to the package directions before unfolding to prevent cracking.
• Use a single sheet. Lay one sheet of puff pastry over the skillet or baking dish, trimming any excess and tucking the edges inside.
• Cut a few vents. Use a sharp knife to cut 3 to 4 small slits in the top so steam can escape while baking.
• Brush with egg wash. For a beautifully golden, glossy finish, brush the top with 1 beaten egg mixed with 1 tablespoon water before baking.
• Keep it cold. Puff pastry puffs best when it’s cold going into the oven, so wait to place it over the filling until just before baking.
• Bake until deeply golden. Puff pastry may need a few extra minutes compared to phyllo dough. If the top browns too quickly, loosely tent it with foil and continue baking until the filling is bubbling.
• Skip the bottom crust. For this skillet pot pie, a puff pastry top crust is all you need. Using puff pastry on the bottom can sometimes become soggy underneath the creamy filling.

Lena’s Tip: Sprinkle the top with flaky sea salt and a few fresh thyme leaves before baking for a beautiful bakery-style finish. The thyme complements the mushrooms and creamy chicken filling perfectly.

Storing tips

The pot pie is best eaten immediately after it’s baked. The longer it sits, the soggier the phyllo will become.

• Make ahead: If you want to make it ahead of time, prepare the filling as normal and store it (once cooled) in an airtight container in the fridge or freezer. When it’s time to eat, pour the filling into an oven-proof skillet, top with the thawed phyllo, and bake as normal (you may need to add a few extra minutes to the cooking time).
• Storing: Any leftovers can be stored in an airtight container in the fridge for 3 to 4 days. Just know that the phyllo won’t be as crispy upon reheating.
