Instructions

  • Put the butter, 2 glugs of olive oil, the sage, and garlic into a heavy-bottomed, non-stick pan. Stir everything round and add the onions, shallots, and leeks. Season with salt and pepper. Place a lid on the pan, leaving it slightly ajar, and cook slowly over medium-low heat for 50 minutes without coloring the vegetables too much. Remove the lid for the last 20 minutes; your onions will become soft and golden. Stir occasionally so that nothing catches on the bottom. Having the patience to cook the onions slowly, slowly, gives you an incredible sweetness and an awesome flavor, so don't be tempted to speed this bit up.
  • When your onions and leeks are lovely and silky, add the stock. Bring to the boil, turn the heat down and simmer for 10 to 15 minutes. You can skim any fat off the surface if you like, but I prefer to leave it because it adds good flavor.
  • Preheat the oven or broiler to maximum. Toast your bread on both sides. Correct the seasoning of the soup. When it's perfect, ladle it into individual heatproof serving bowls and place them on a baking sheet. Tear toasted bread over each bowl to fit it like a lid. Feel free to push and dunk the bread into the soup a bit. Sprinkle with some grated Cheddar and drizzle over a little Worcestershire sauce.
  • Dress your reserved sage leaves with some olive oil and place one on top of each slice of bread. Put the baking sheet into the preheated oven or under the broiler to melt the cheese until bubbling and golden. Keep an eye on it and make sure it doesn't burn! When the cheese is bubbling, very carefully lift out the baking sheet and carry it to the table. Enjoy.
