Spaghetti al Forno

Ingredients

• 1 1/2 tablespoon(s) olive oil, plus more for drizzling
• 1 small onion, finely chopped
• 2 carrots, peeled and finely chopped
• 1 stalk(s) celery, finely chopped
• 4 clove(s) garlic, minced
• 1 can(s) (28 ounces) diced tomatoes
• Salt and freshly ground pepper, to taste
• 1/2 pound(s) whole wheat spaghetti or linguine
• 2 tablespoon(s) chopped flat-leaf parsley
• 1 large pinch red pepper flakes
• 3/4 cup(s) grated Parmesan cheese
• 2 tablespoon(s) whole wheat breadcrumbs

Directions

1. 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. 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. 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.
