Ingredients
1 1/2 ounces bacon, finely chopped
1 tablespoon extra-virgin olive oil
1 medium onion, chopped
6 ounces cremini mushrooms, quartered
3 medium carrots, sliced 1/4 inch thick
1 celery stalk, thinly sliced
Coarse salt and freshly ground pepper
1/4 cup plus 1 1/2 teaspoons all-purpose flour
3 cups chicken stock
2 1/4 pounds boneless, skinless chicken breast halves and thighs, cut into 1-inch cubes
3 tablespoons heavy cream
1 disk Pate Brisee
All-purpose flour, for surface
1 large egg, lightly beaten for egg wash
Preparation
Make the filling: Cook bacon in a large saucepan over low heat until crisp, about 10 minutes. Transfer bacon to a plate using a slotted spoon. Raise heat to medium, and add oil. Add onion, and cook until translucent, about 8 minutes. Add mushrooms, carrots, and celery, and cook until softened, about 10 minutes. Season with salt and pepper. Stir in flour.
Add stock, and bring to a simmer. Cook until thickened, about 5 minutes. Add chicken and cream. Simmer until chicken is just cooked through, about 5 minutes. Return bacon to saucepan. Let cool.
Divide filling among eight 4-inch (12 ounce) ramekins.
Preheat oven to 375 degrees. Make the topping: Roll out pate brisee to a 1/4-inch thickness on a lightly floured surface. Cut out 8 circles that are 1 inch wider than the ramekins. Top ramekins with dough, and crimp edges with a fork to seal. Brush dough with egg wash. Freeze for 20 minutes.
Bake until toppings are golden and fillings are bubbling, about 40 minutes.
