Preheat oven to 450°. In a greased deep 2-1/2-qt. baking dish, combine first four ingredients. In a small saucepan, melt butter over medium heat. Stir in flour and thyme until blended; gradually whisk in broth and bouillon. Bring to a boil, stirring constantly; cook and stir until thickened, about 2 minutes. Pour over vegetable mixture.
