  • 1 ½
    cups cremini mushrooms, chopped
  • 1 ½
    pounds chicken breasts, cubed 
  • 2
    tbsp all-purpose flour

  • egg + 1 tablespoon water, beaten

Directions

  • 1 Preheat oven to 400°F.
  • 2 In an oven-safe 12-inch sauté pan or cast iron skillet, heat oil over medium heat. Add leeks and carrots and sauté until soft, about 8 minutes. 
  • 3 Add mushrooms and chicken and sauté for 5 minutes. Sprinkle flour over, stir, and cook for 2 minutes.
  • 4 In a bowl, whisk to combine vinegar, miso, mustard, and broth. Pour over chicken, stir, and bring to a boil. Remove from heat.

  • 6 Bake for 40 minutes until the pastry is golden. Serve.
