Slow Cooker French Onion Soup

I came by a large amount of past their best onions last week.  I peeled and trimmed them, and then recalling a slow cooker onion soup recipe, decided to caramelise them in the slow cooker whilst I got on with a lot of other cooking on the hob.

It is a slow recipe - about 18 hours - but a very hands off one (apart from slicing all the onions)

Serves 6

2kg onions, peeled and thinly sliced

1 large garlic clove, peeled and crushed
1 tbsp light olive oil
1 tbsp butter

1.5l boiling water

200ml white wine

3 organic beef stock cubes

2 tbsp plain (or gluten free) flour 

Put the sliced onions in a slow cooker on low overnight with the oil and butter.  The recipe I read online said 10 hours minimum. I put mine on high around 7pm, then down to Low at 11pm. The next morning at 8am they were only just caramelising, with a surprising amount of liquid. 

I kept them on low until 11am, then added the water, crumbled stock cubes, wine, garlic, and flour mixed with a little water until pourable.  Mix well, and leave for another couple of hours, stirring occasionally.
