Will try this sounds scrummy, but I'm planning to 'do' a big batch of onions so I can keep half back for French Onion Soup the next day!

One of our favourite recipes. Have used soda bread instead of sourdough bread, was just as tasty. One tip, you definitely need a really strong, tangy cheese to bring out the sweetness of the caremelised onions.

I topped this with the cheese society welsh rarebit (from this site too!)which improved it even further and served it with a rocket and walnut salad FAB!!!!

Delish!! Loved these, made it for a light lunch one day and was so impressed by the taste am planning to turn it into my Easter starter. Managed to scale it down for 2 by using 3 onions (had a bit left over). Onions became really sweet and the brandy made it feel really indulgent.
