Ingredients:
1 tablespoon olive oil
6 garlic cloves, crushed plus
6 additional garlic cloves, to be used later
2 leeks, thoroughly washed and sliced
1 kg yellow onions (Americans) or 1 kg brown onions ( Australians)
2 (400 ml) cans tomatoes, drained and diced
6 cups chicken stock ( or vegetable)
3 tablespoons chopped Italian parsley ( flat leaf)
salt
fresh ground black pepper, to taste
2 -3 tablespoons balsamic vinegar
butter (optional)
3 slices day-old sourdough bread, cubed, to form croutons
pecorino cheese, grated
Directions:
Heat the oil in a non-stick pot and saute the garlic, leek and onions for about 30 minutes until golden brown, regularly stirring and scraping the bottom of the pot, turning down the heat after about 10 minutes. (You may need more oil if you are not using a non-stick pot).
Add the tomatoes, stock, parsley, seasonings and balsamic vinegar. Mix well and bring to the boil. Then simmer for about 20 minutes.
Preheat the oven to 180 C.
While the soup is cooking, heat a little oil, butter and the remaining 6 cloves of garlic in a heavy-bottomed pan (that can go into the oven).
Add a couple of handfuls of the day-old bread, cubed and toss until well coated. Then cook in the oven until golden.
Transfer the croutons to a bowl and toss with a good handful of pecorino whilst still hot.
To serve, ladle the soup into individual bowls and top with the croutons and an extra sprinkling of cheese.
