Heat the oven to 350°F.
2
Cut the tops off of each garlic bulb to expose cloves. Place the bulbs cut side up on a large piece of foil. Drizzle bulbs with the oil, then wrap a piece of foil around the bulbs tightly. Place in a baking dish and bake 45 to 50 minutes or until garlic is tender. Cool slightly. Squeeze soft cloves out of the skins, finely chop, then set aside.
3
While the garlic is baking, place each chicken breast between 2 pieces of plastic wrap; gently pound with flat side of a meat mallet until about 1/4 inch thick. In a shallow pan, mix together the flour, thyme, salt and pepper. Reserve 3 tablespoons of the seasoned flour for the sauce. Coat the chicken with remaining flour mixture.
4
In a large skillet, heat 2 tablespoons of the butter over medium-high heat. Cook the chicken for 6-8 minutes until no longer pink in center (165°F with a thermometer), turning once. Place chicken on a plate and cover to keep warm.
5
In the same skillet, heat the remaining butter. Cook mushrooms over medium heat until lightly browned. Sprinkle the reserved seasoned flour over the mushrooms. Cook and stir for about 2 minutes. Mix in the chicken broth, milk and roasted garlic. Bring to a boil. Reduce heat to low; simmer about 3 minutes or until slightly thickened.
6
Add chicken to the skillet with sauce and heat for 1 to 2 minutes.
