How to cook deliciously - Spaghetti al Forno

1 . Stage

To make sauce: In a large saucepan, heat oil over medium heat. Add onion, carrots, celery and garlic. Cook, stirring frequently, until vegetables begin caramelizing, about 12 minutes. Turn heat to low; cook until very soft, 10-15 minutes. Raise heat to medium; add tomatoes. Bring to a simmer and partially cover. Cook 30-40 minutes, stirring occasionally. Season with salt and pepper.

2 . Stage

Preheat oven to 450 degrees. Bring a large pot of water to a boil. Cook spaghetti according to package directions, subtracting several minutes off cooking time so it comes out very al dente.

3 . Stage

Drain well; add to sauce. Add parsley and red pepper flakes; toss to combine. Transfer to a 2-quart baking dish. Spread level. Sprinkle with cheese and bread crumbs. Drizzle with olive oil. Bake until top is browning and sauce is bubbling, about 15 minutes. Serve immediately.
