Marinara is a red sauce consisting of olive oil, garlic, tomatoes, and herbs. Onions might sometimes get added to the combination of these ingredients, and marinara might be transformed into another sauce such as arrabbiata or puttanesca with the addition of different ingredients.
Due to its simplicity, marinara acts as a versatile base for many Italian dishes. It originated in Naples in southern Italy, its name derived from the Italian word for sailors (marinai). Some say it was named after the sailors because marinara's ingredients didn't spoil easily, and the sauce could be prepared quickly, in about the same time it took pasta to cook, so the two made a flavorful and cheap meal for sailors on their voyages.
