Preparation Preheat oven to 375°F. Toss shallots with 2 tablespoons oil on baking sheet; spread in single layer. Sprinkle with salt and pepper. Bake until tender and golden brown, stirring occasionally, about 35 minutes. Stir 2 tablespoons oil and breadcrumbs in skillet over medium heat until crumbs brown, about 4 minutes. (Shallots and crumbs can be made 8 hours ahead. Cover separately; keep at room temperature.) Cook pasta in large pot of boiling salted water 10 minutes.
