Slow-roasting tomatoes brings out a unique depth of flavor. Use meatier tomato varieties, such as Roma, Brandywine, Black Krim, or even cherry tomatoes. After roasting, these tomatoes must be stored in the refrigerator; packing them in oil will keep them from drying out too much.

Roasting tomatoes low and slow draws out their natural sweetness and concentrates their flavor. Stephanie Thurow
