Though ketchup and tomato sauces are both tomato-based foods but they are different in flavor, composition, usage, and cultural purpose. Ketchup is a sweet and tangy food, while tomato sauce is made with crushed or pureed tomatoes. Ketchup is thick and smooth, almost like jelly. On the other hand, tomato sauce is lightweight and simple in texture. It has a more natural tomato flavor with herbs, onion, garlic, and others than ketchup.
This is typically less sweet, but ketchup is a sweet-based food. Ketchup is sweet, vinegary, and cold, while tomato sauce is savory, herby, and cooked. Using ketchup as a tomato sauce substitute in pasta or Italian cooking changes the dish’s character completely, often making it overly sweet and artificial. Ketchup is a condiment, but tomato sauce is a cooking ingredient that is used to prepare any dish. Ketchup is designed to be a standalone condiment, often served cold with foods like chips, burgers, and hot dogs.
