Instructions

Do Ahead:
    Cup of Yum
  1. Preheat the oven to 425 degrees F.
  2. Shred the meat of the Rostisserri chicken and discard the skin and bones. You will have 4 to 6 cups of shredded chicken.
  3. Place a 9 x 13-inch baking dish on a baking sheet.
For the Chicken Mixture:
  1. Shred the meat of the Rostisserri chicken and discard the skin and bones. You will have about 4 heaping cups of shredded chicken.
  2. In a large pot, melt the butter and saute the onions, celery, and poblano pepper over medium-low heat for about 10 minutes, until the vegetables soften.
  3. Add the garlic and cook until fragrant, about 1 minute more. Add the brandy or wine, scrape up all the brown bits of the pan and cook for 2 minutes.
  4. Whisk in the flour and cook over low heat, constantly stirring, for 2 minutes and then keep stirring as the hot broth is added to the sauce. Add the corn, carrots/peas, black pepper, nutmeg, thyme, rosemary, sage, and shredded chicken. Simmer over low heat, occasionally stirring for 10 more minutes, stirring, until thick. Add heavy cream and cilantro or parsley and mix well and cook for 5 more minutes, stirring occasionally. Taste and adjust seasoning, if necessary.
For the Homemade Crust:
  1. In a food processor with a metal blade, combine flour, salt, and baking powder. Add the cold butter and cold shortening and quickly coat each piece with flour—pulse about 10 times or until it is the size of peas.
  2. Add the ice water with the motor running; process only enough to moisten the dough and have it just come together. Dump the dough onto a floured board and knead quickly into a ball. Wrap the dough in plastic and allow it to rest in the refrigerator for 30 minutes.
To Assemble & Fill:
  1. Preheat the oven to 375 degrees F and set an oven rack to the center position—Line a baking sheet with aluminum foil for easy clean-up. For the Homemade pastry, roll out the pie dough and cut it to fit over the 9 by 13 baking dish. Next, pour the filling into a 9 by 13 baking dish.
  2. In a small bowl, beat the egg with 1 tablespoon of water. Then, carefully place the homemade dough over the filling and press the dough onto the sides of the dish to seal the edges. Next, use a fork to crimp the edges. Finally, brush dough with egg wash, and using a paring knife, cut slits in the top of the crust to allow the steam to escape while baking.
To Bake:
  1. Place the baking dish on the foil-lined baking sheet. Bake the Chicken Pot Pie Casserole for 55 to 60 minutes or until the crust is golden brown and the filling is bubbling hot. Let pie rest for 15 minutes before serving. Enjoy Our Chicken Pot Pie Casserole!
