We often consider tomato sauce a job for the stovetop, expecting a slow burble in a saucepan.
But Rachel Strecher—via Canal House—has shared a method on our (Not)Recipes app for passing that work onto your oven—and your dinner guests or family members. Along the way, you'll give the "sauce" some additional flavor and texture, too.
Instead of making stovetop sauce, hollow out good tomatoes and fill them with breadcrumbs that have been toasted in olive oil and anchovies (you can add pancetta, too) and mixed with herbs. Then, bake at 350° F for about an hour, until collapsing.
When the tomatoes are almost at that point, boil spaghetti, saving 1/2 cup of water. Take the baking dish out of the oven, spoon all of the oily, tomato juices that have pooled at the bottom onto the pasta, and pour in the reserved pasta water (starch becomes creaminess). Toss together, then distribute the noodles among bowls and plop tomatoes on top.
As you slice, you'll get sauce!
