Fill a large pot with water (about 2-3 quarts) and bring to a boil over high heat. Season generously with salt and add the pasta. Cook according to the package instructions for al dente (the pasta will cook more in the sauce). Reserve about 1 1/2 cups of pasta water, then drain and set aside.
In a large skillet over medium-high heat, warm the olive oil. Add the tomatoes and ½ teaspoon salt and cook for 7-10 minutes or until the tomato juices have reduced and it is starting to look “saucy”, stirring occasionally.
Add the tomato paste, garlic, and red pepper flakes (if using) and cook for 2 more minutes, stirring often. Add the pasta, remaining ½ teaspoon salt, and 1 cup pasta water and stir to combine.
Simmer over medium heat for about 3-5 more minutes or until the sauce reduces and coats the noodles, stirring occasionally. You can always add more pasta water (or just warm water) to thin out the sauce, if needed.
Serve topped with basil, plenty of parmesan, and a drizzle of good olive oil.
