Total Cost - £9.25 - This covers absolutely everything. All we assume you have in your kitchen beforehand is SALT, PEPPER AND OLIVE OIL.
Finely slice 7 onions. Add a large knob of butter and a glug of olive oil to a frying pan. Fry the onions on a low heat until very soft and caramelised.
Add 2 tablespoons of flour to the onions and mix it in. Add a litre of beef stock, bit by bit. Mix everything together.
Add 3 bay leaves and a small handful of thyme leaves. Mix them in, pour in your white wine, add your onions and season with salt and pepper.
Bring the soup to the boil, reduce the heat and simmer for 35 minutes.
In the meantime, cut your baguette into slices. Add the slices to a tray and grate 75g of gruyere over the top. Place croutons in the oven for 30 minutes or until golden and crisp.
Once the croutons are ready, remove them from the oven and place them on top of the soup, which should be dark and thick at this point.
Grate the remainder of the gruyere over the top. Place the soup under the grill for 10 minutes until the cheese is golden and bubbling.
Serve up the soup into individual bowls and tuck in!
