For the slow cooker French onion soup:
- 4 large onions sliced
- 30 g (~ 2 tbsp) butter, roughly chopped
- 1 tbsp caster sugar (optional)
- 1 tbsp balsamic vinegar
- 2 tsp minced garlic or garlic puree
- 1 tsp dried thyme
- 1 tsp black pepper
- 750 ml (~ 3 cups) vegetable stock
For the cheesy crouton:
- 2-4 thick slices French baguette
- 2-4 tbsp grated cheese (I used cheddar)
Add all of the soup ingredients to a slow cooker, and mix well to break up the onions. Cook on high for approximately 9 hours, or until the onions are a deep, rich brown colour, and very soft.
Serve on its own, or with a cheesy crouton. To make the cheesy crouton, dish up a bowlful of soup into a heat-safe bowl, and top with 1 or 2 thick slices of French baguette. Sprinkle over plenty of grated cheese, then place under a grill (broiler) for a few minutes, until the cheese is melted and slightly crispy. Serve immediately.
