A few sprigs of fresh herbs, such as rosemary or thyme
Directions
Preheat oven to 300 degrees F . Line a rimmed baking sheet with parchment paper. Arrange tomatoes on prepared baking sheet in one layer, season with salt, and drizzle all over with olive oil. Scatter herbs on top, if using. Transfer to oven and cook until excess juices have evaporated and tomatoes look slightly dry on the exterior but still moist within, 1 to 2 hours. Discard herbs, if necessary.
