Heat the olive oil in a large saucepan over medium heat.

Sauté the chopped onion until it becomes translucent, about 5 minutes.

Add the minced garlic and cook for another minute until fragrant.

Pour in the crushed tomatoes, stirring to combine with the onion and garlic mixture.

Add the sugar, dried oregano, and dried basil.

Bring the sauce to a gentle simmer and reduce the heat to low.

Allow it to cook for about 20 minutes.

Taste the sauce and season with salt and pepper as needed.

Blend for smoothness if desired.

Let it cool before storing in an airtight container.
