Heat the oven to 350°F. Stir the goat cheese, chopped thyme, and olive oil together in a small bowl until blended. Spread the cheese mixture in a ceramic crock or small gratin dish -- no need to get it perfectly even. Drizzle the cheese with a bit more olive oil and top with a few grinds of black pepper. Lay the thyme sprigs on top. Bake the cheese until its warm and creamy, about 10 minutes. Serve this topping family-style in a little gratin dish, and let guests spread the warm cheese on the bread themselves. Yields about 1 cup.
