Florentine Caramelised Onion Soup

    3 hours 25 min

    Also known as "carabaccia", this is a local specialty in Florence, and is hard to find even in cookbooks specialising in Italian soups! The effect should be rich and somewhat sweet (but not too much). Adding roasted garlic would be a good variation.

    Serves: 6 

    • 4 tablespoons extra virgin olive oil
    • 1.8kg onions
    • 2 teaspoons caster sugar
    • salt to taste
    • 1 (750ml) bottle dry white wine
    • 1 litre chicken stock

    1. In a large heavy pot, heat oil over medium heat. Cut onions in half lengthways, then slice thinly. Place sliced onions in pot and toss to coat with oil. Cover, reduce heat to medium-low, and cook, stirring occasionally, until onions are softened and beginning to colour, 30 minutes.
    2. Increase heat to medium and cook, stirring occasionally, uncovered, until onions are amber in colour, 45 minutes.
    3. Sprinkle onions with sugar and a little bit of salt; cook, stirring, until sugar melts and onions are caramel coloured, 5 minutes. Pour in wine and stock, and place cinnamon stick in pot. Bring to the boil, then reduce heat, cover and simmer 1 hour.
    4. Stir the bread into the soup and cook, uncovered, stirring occasionally until the bread disintegrates, 30 to 45 minutes.
    5. Remove the cinnamon stick. Whisk the soup to incorporate the bread. Adjust seasoning. Serve hot.

    This was so good! It took a long time to actaully cook, but it only took about 10 minutes to prepare! And then you just simmer it and forget it! It was good!  -  25 Oct 2001  (Review from Allrecipes US | Canada)


    Great recipe...I added only half the wine and in addition at the end of cooking time some Gruyere cheese as a topping for the finished soup. This is authentic and wonderful.  -  06 Jan 2011  (Review from Allrecipes US | Canada)


    Made EXACTLY as stated. I'm sorry to rate this so low, but it was we did not care for it, and we could not eat it. My husband and teenaged sons who are quite adventurous when it comes to food all, after 2-3 tastes, pushed their bowls back and said they didn't like it. Oh, well. I know this is a legitimate recipe because I did a search and found very similar variations. I like the history of the recipe, but it is just too sweet. The incorporation of the bread just made it look a mess. Not a visually appealing meal either. Will stick to French Onion Soup.  -  06 Jan 2012  (Review from Allrecipes US | Canada)
