Ingredients

  • 4 large shiitake mushrooms
  • 4 carrots, peeled
  • 2 medium-size zucchini
  • 4 tablespoons butter
  • 4 skinless boneless chicken breasts, about 4-5 ounces each, slightly flattened with a meat pounder
  • 8 teaspoons Dijon mustard
  • 4 teaspoons finely chopped shallots
  • 4 teaspoons fresh thyme or 2 teaspoons dried
  • 4 tablespoons white wine
  • 4 tablespoons finely chopped parsley
  • Salt and freshly ground white pepper to taste

Method

  • Preheat oven to 450 degrees.
  • Spread a large piece of aluminum foil on a flat surface.
  • Invert a 12- or 14-inch round cake pan on it and trace around the edge with a sharp knife to make a circle.
  • Repeat until there are 4.
  • Cut off and discard the stem of each mushroom and cut caps into thin slices.
  • Cut carrots crosswise into 1 1/2-inch lengths.
  • Cut each piece lengthwise into a julienne shape.
  • Trim and wash zucchini, and cut in the same fashion.
  • Melt 2 tablespoons butter in a saucepan.
  • Place aluminum rounds on a flat surface and brush them with melted butter.
  • Place one chicken breast on each round slightly below the center, leaving a margin large enough to fold over.
  • Brush the top of each breast with about 2 teaspoons of mustard and place equal quantities of mushrooms, carrots, zucchini, shallots, thyme around each.
  • Sprinkle each serving with a tablespoon of white wine and parsley, and dot with remaining butter.
  • Salt and pepper to taste.
  • Fold foil to completely enclose the contents while leaving some room for expansion.
  • Crimp the seal as tightly as possible.
  • Arrange packages on a baking sheet and bake about 20 minutes.
  • Serve immediately.
