Why This Recipe Works

What we love about this recipe is how easy it is to assemble, as slow-cooked cherry tomatoes, when combined with lots of fresh herbs, needed little embellishment. First, we simply microwaved the aromatics—onion, garlic, and oregano—with tomato paste and a little oil until softened and added them to the slow cooker along with halved cherry tomatoes. In the slow cooker, the tomatoes collapsed and softened, becoming even sweeter and more flavorful as they absorbed some of the flavor of the aromatics. To ensure that our sauce had the right texture, we added a little tapioca. Still, the sauce wasn't quite thick enough, which wasn't surprising given that the slow cooker allows for almost no evaporation, so at the end of the cooking time we simply mashed the tomatoes a little with a potato masher. To finish, we added a dose of basil and parsley for freshness.
