Preparation
Step 1
Put oven rack in middle position and preheat oven to 500°F. Line a shallow baking pan with foil.
Step 2
Coarsely grate cheese and set aside in a medium bowl. Pulse mushrooms and shallot in a food processor with thyme, 3/4 teaspoon salt, and 1/4 teaspoon pepper until finely chopped.
Step 3
Heat 2 tablespoons butter in a 10-inch heavy skillet over moderately high heat until foam subsides, then sauté mushroom mixture, stirring occasionally, until lightly browned, about 5 minutes. Stir into cheese (some cheese will melt).
Step 4
Pat chicken dry, then cut a deep 3-inch-long pocket horizontally in long curved side of each chicken breast half and fill each pocket with one fourth of cheese mixture (some filling will be visible).
Step 5
Put chicken in baking pan, then melt remaining tablespoon butter and brush over chicken. Sprinkle with remaining 1/2 teaspoon salt and remaining 1/4 teaspoon pepper. Roast until cooked through and cheese is melted (filling will ooze), 20 to 25 minutes.
