Place the tomatoes, garlic, olive oil, and basil in a pot or saucepan over medium heat, and bring them to a gentle simmer.
Sprinkle some salt into the sauce and allow the whole tomatoes to cook until they have softened enough to be easily mashed with a fork into a pulpy texture.
Let the sauce simmer partially covered for about 25-30 minutes, or until it thickens to your desired consistency.
Adjust the seasoning by adding more salt if needed. Remove the garlic clove before storing the sauce in the refrigerator for up to one week.
