How to Make It
Preheat oven to 400°F. Place tomato wedges, cut side up, on a rimmed baking sheet lined with aluminum foil. Spray with cooking spray. Place bread on a separate rimmed baking sheet. Bake in preheated oven until tomatoes are lightly charred, undisturbed, 45 to 50 minutes. Bake bread until lightly toasted, 15 to 20 minutes, stirring once halfway through.
Whisk together milk, salt, pepper, and eggs in a large mixing bowl until smooth. Toss roasted tomatoes, bread, and cherry tomatoes in egg mixture to coat. Transfer mixture to a 13- x 9-inch baking dish coated with cooking spray. Cover tightly with aluminum foil.
Bake at 400°F until set, 30 to 35 minutes. Uncover, and top with goat cheese. Bake until cheese is melted and lightly browned, 10 to 15 minutes. Sprinkle with thyme. Let stand 5 minutes before serving.
