Peel and cut your vegetables. Make a purée of the carrots, onions, celery and 2 cloves of garlic in a blender.Tip: For an even easier version, you can just use and onions, and it’ll still taste great.
Sauté the vegetables in the olive oil for about 10 minutes, until they lose their water content.
Add tomato purée (passata di pomodoro) and remaining 4 cloves of garlic and let it simmer for 15 minutes in a low heat. The longer you cook, the better it gets. But for a fast meal it’s totally OK to simmer just for 15 minutes. Add salt, pepper, basil and oregano to taste.
