Chicken Pot Pie

To poach the chicken, place vegetables, garlic, lemon, herbs in a pot. Add chicken and enough water to just cover the bird. Bring to a boil, add peppercorns and salt. Reduce heat to a low rolling boil.  Poach chicken 60 minutes, turning occasionally.  Cool completely in stock and remove chicken.  Discard bones and skin and pull or dice chicken into bite-size pieces; reserve. Strain stock and pour back into pot, keep warm.  

 

Preheat oven to 400°F.

 

Heat olive oil in a large, deep skillet over medium to medium-high heat; add butter. When it foams, add mushrooms and brown 7-8 minutes. Add thyme, carrots, celery, potato, shallots, leeks and garlic; season with salt and pepper. Cook, stirring occasionally, partially covered 4-5 minutes more to soften; sprinkle flour over pan and stir 1 minute. Add sherry or wine and stir to reduce by half. Add poaching liquid and simmer to thicken 5 minutes. Add Dijon, heavy cream, cheddar cheese, tarragon, peas, reserved chicken and heat through. Add more poaching liquid if too thick. Reduce heat to low.

 

If making ahead, make filling completely and cool. On the night you want to serve, heat the filling and bake off puff pastry tops.

 

Place pastry sheets on a floured surface. With a sharp paring knife, trace the shape of the individual serving bowl into the puff pastry. Place shapes on a parchment-lined baking sheet and brush with egg wash. Cut a few vents in the top. Bake until golden brown. 

 

Serve filling in bowls topped with pastry crust.
