Ingredients

Knob of unsalted butter
3 tbsp rapeseed oil
750g (about 3 large) onions, cut into thin wedges
2 large garlic cloves, finely chopped
Handful of fresh thyme leaves
300ml white wine
50ml Madeira
1 litre beef consommé or good-quality beef stock, hot
Small crusty baguette or similar
100g Gruyère, coarsely grated
Nutmeg for grating

Method

Heat the butter and oil in a shallow flameproof casserole, add the onions and cook gently for 30 minutes, stirring occasionally, until soft, golden and lightly caramelised. Stir through the garlic and thyme, then cook for 10 minutes more.
Pour over the white wine and Madeira, then bubble until reduced by half. Add the hot consommé or stock, then simmer for 10-15 minutes. Taste and adjust the seasoning.
Meanwhile, preheat the grill to medium-high, cut the baguette diagonally into 8 slices, then lightly toast on both sides. Place on a baking sheet, top each with Gruyère and a good grating of nutmeg, then grill for 3 minutes or until the cheese has melted. Serve the soup, ladled into warm bowls, with the Gruyère toasts.

Use red onions and blue cheese such as Stilton or Stichelton for a bit of a twist on this classic.
Freeze the finished soup, once cooled, in a well-sealed plastic container for up to 3 months. Defrost completely before reheating and making the toasts.
