Method · 3 h 45 min

Place the dried mushrooms in a small heat-proof bowl and cover with boiling water. Let sit for 30 minutes until warm to the touch and softened.
Lift the mushrooms out of the soaking liquid (sediment will settle to the bottom), coarsely chop and set aside.
Heat a large Dutch oven or other pan over medium-high heat and add 2 tablespoons of butter.
Once the butter has melted add the chicken thighs.
Season with ½ teaspoon salt and cook on both sides until golden brown and just cooked through.
Remove the chicken from the pan, coarsely chop, and set aside.
Add the remaining 2 tablespoons of butter, and the onion, celery, carrot, and butternut squash to the pan. Cook and stir occasionally until the vegetables have softened slightly (about 10 minutes).
Add the fresh mushrooms and cook until the juices are released (about 10 minutes more).
Add the sherry and stir, scraping up the browned bits from the bottom of the pan.
Stir in the peas and the chopped soaked mushrooms.
Sprinkle the vegetables with ¼ cup of the flour.
Stir to coat and cook for 1 minute, stirring constantly.
Add the cooked chicken, herbs, and remaining salt to the pan.
Stir in the chicken broth and cook until the mixture thickens slightly.
Add the sour cream and reduce the heat to low. Cook and stir for another minute or until the consistency is quite thick. Remove the pan from the heat.
Preheat the oven to 425 F.
Oil a 13 x 9-inch baking or casserole dish.
Add the filling and spread into an even layer. Allow the filling to cool slightly while rolling out the pastry.
Sprinkle a work surface with a little of the remaining flour.
Roll 1 sheet of the pastry out into a 14 x 10-inch rectangle.
Use a pizza wheel or sharp knife to cut the pastry into 12 strips lengthwise.
Repeat the process with the second pastry sheet, but this time cut the strips in the opposite direction.
Lay the shorter strips across the filling from side to side to fit.
Fold back every other strip.
Lay one of the longer strips across in the opposite direction.
Fold back the strips over the top.
Repeat this process working down to the bottom edge of the pan, folding back alternating strips each time and repeating for the second half of the pan.
Use any extra strips to press around the edges of the pan.
Crimp the edge using a fork.
Whisk together the egg with 1 teaspoon water in a small bowl.

A rich filling of boneless and skinless chicken thighs, fresh and dried mixed mushrooms, butternut squash, English peas, and aromatic vegetables and herbs balances the umami of mushrooms with the sweetness of winter squash and peas. The flavorful filling is topped with an impressive lacquered puff pastry crust, made with the ease of purchased frozen dough. Once baked, this pot pie creation is elegant enough for a dinner party centerpiece or a special holiday meal, yet perfect for cozy dinners any night of the week. Kinnaird shares some tips for advance preparation as well as for learning to work like a pro with the often intimidating puff pastry dough.

Gather the chicken, mushroom, and winter squash pot pie ingredients

This hearty pot pie is infused with plenty of mushroom flavor, starting with a small amount of mixed dried mushrooms. These can include porcini, trumpet, oyster, or any of your favorite varieties. These mushrooms are given a simple soak in hot water to reconstitute, or you can try this fun French press hack. Boneless, skinless chicken thighs are browned in unsalted butter and seasoned with kosher salt, then removed and chopped. A "mirepoix," or combination of diced onion, celery, and carrots is then sauteed with cubed butternut squash. Fresh cremini mushrooms are cooked down with the vegetables, then dry sherry is used to deglaze the pot. Fresh English peas, reconstituted mushrooms, fresh sage, and thyme, plus the chopped chicken are added back in. A sprinkle of all-purpose flour helps create a sauce along with low-sodium chicken broth and sour cream. Packaged frozen puff pastry sheets are thawed and rolled out, cut into strips, and formed into a lattice over the chicken and vegetable filling. An egg wash made from one whole egg plus water creates a sheen on the baked dough.
