This is a great soup taken pretty much straight from the BBC Food website (a fantastic resource if you’ve never used it – also check out BBC GoodFood). Very simple, reasonably quick, damn tasty and quite a bit lighter than the much-vaunted French Onion soup.
4 medium onions, 3 diced, 1 sliced
2 cloves garlic, finely chopped
1 large baking potato, cut into 2cm cubes
white wine vinegar
few sprigs fresh thyme (or a pinch of dried)
3 bay leaves
handful fresh rosemary, finely chopped
1 litre stock
salt and pepper
Heat a big old glob of butter in a large saucepan, add the 3 diced onions, a good twist of salt and pepper and sweat over a low heat for 10 minutes. Add the garlic, rosemary and thyme and continue to sweat for a further 5 minutes.
Add a glug of white wine vinegar, the bay leaves and pour in the cider (I doubt you’ll be able to find a 250ml bottle so I guess you’ll just have to drink the rest!). Increase the heat and reduce by half before adding the stock and potato. Keep on a simmer until the potato is cooked through.
Meanwhile heat a little more butter in a frying pan and once melted added the sliced onion, a little salt and pepper. Fry up over a medium heat until starting to golden. Crumble in a little of the stilton, give a good stir and fry for a further 2-3 minutes. Turn off the hob but leave the frying pan on it while you use a stick-blender to zhuzzzhhh up the soup.
Serve the soup in bowls (bowls, for soup – what is this craziness?!) topped with fried cheesy onions and a further crumbling of stilton. Enjoy with friends – I dare you not to eat the whole lot!
