1pound fresh tomatoes, chopped, or 1 28-ounce can whole tomatoes, drained and chopped
1 onion, sliced
6 cloves garlic, sliced
1/2 teaspoon red chile flakes, or to taste
3 tablespoons olive oil
Salt and pepper
1cup fresh basil leaves, chopped
Grated Parmesan cheese, for serving (optional)
Instructions
Put the pasta, tomatoes, onion, garlic, red chile flakes, oil, and 4 cups water in a large skillet over high heat. Sprinkle with salt and pepper. Bring to a boil and cook, stirring and turning the pasta frequently with tongs, until the pasta is al dente and the water has nearly evaporated, about 9 minutes.
Season to taste with salt and pepper, stir in three quarters of the basil, divide among 4 bowls, and garnish with the remaining basil and the Parmesan, if you’re using it.
