In a saucepan over medium heat, warm the olive oil. Add the finely chopped onion and cook for 3–5 minutes until soft and translucent. This step builds the base flavor.

Add minced garlic and cook for another 30 seconds, stirring constantly to prevent burning.

Stir in the crushed tomatoes, tomato sauce, tomato paste, and water. Mix thoroughly until the paste is fully incorporated and the sauce is smooth.

Add dried basil, dried oregano, onion powder, sugar, salt, and black pepper. Stir well to evenly distribute the seasoning.

Turn the heat down to low after bringing the sauce to a gentle simmer. Cover partially and let it simmer for 30–60 minutes, stirring occasionally.

The longer it simmers, the thicker and richer it becomes—just like classic Prego.

Taste the sauce and adjust seasoning if needed. Add more sugar for sweetness or a pinch of salt to enhance flavor.

Serve immediately or let cool for storage.
