Step 1

Preheat oven to 325 degrees. Mix together tomatoes and garlic in a nonreactive 9-by-13-inch baking dish. Whisk together oil, vinegar, thyme, brown sugar, and salt in a bowl. Drizzle over tomato mixture.

Step 2

Bake until tomatoes are softened and caramelized, about 1 hour. Serve warm or at room temperature. Sauce can be stored in refrigerator up to 5 days; let cool before storing.
