Bucatini with Cauliflower and Brussels Sprouts

In a large pot of boiling salted water, cook the pasta until al dente. Drain the pasta, reserving 1/2 cup of the cooking water. Meanwhile, in a large, deep skillet, heat 1/4 cup of the oil. Add the cauliflower and brussels sprouts and season with salt and black pepper; cover and cook over moderately high heat, stirring occasionally, until lightly charred and crisp-tender, about 5 minutes. Add 1/4 cup of oil to the skillet along with the onion, garlic, anchovies, crushed red pepper, rosemary and thyme; cook, stirring, until the onion is slightly softened, about 3 minutes. Cover and cook over low heat until the cauliflower and sprouts are tender, about 3 minutes. Keep warm. In a small skillet, heat the remaining 2 tablespoons of olive oil. Add the bread crumbs and cook over moderately high heat, stirring, until golden and crisp, about 4 minutes. Season with salt and transfer to a bowl. Add the pasta and reserved cooking water to the vegetables and cook over moderate heat, tossing, until the water is nearly absorbed. Remove from the heat and stir in the 1/2 cup of grated cheese. Serve the pasta in wide bowls, passing the bread crumbs and additional cheese at the table.
