In a large pot, cook spaghetti as directed on the packaging but remove from the pasta water about 3 minutes before it’s finished cooking. Reserve the pasta water.
Meanwhile, in a large pan, heat the oil on medium heat and sauté garlic until fragrant, about 30 seconds.
Add tomatoes and sauté until soft. Add 1 cup pasta water and bring to a boil.
Remove the pasta from the water about 3 minutes before it’s done cooking (very Al dente) and add to the sauce in the pan.
Add ½ cup more pasta water and continue to cook until pasta is cooked to desired doneness. Add more pasta water if desired.
Serve with Parmesan, if desired. Enjoy!
