Equipment

Ingredients
  

  • 3 large White onions
  • 3 large Red onions
  • 3 tbsp Olive oil
  • 40 grams Butter
  • 1 tsp Brown sugar
  • 4 cloves Garlic
  • 200 ml White wine (Alternatively use 200ml of lager or stout)
  • 1.2 litres Beef stock
  • 2 Bay leaves
  • 2 tsp Fresh thyme leaves Tied in a sprig or very finely chopped (Or 1 tsp dried thyme)
  • 6 slices Baguette, Crusty bread
  • 400 grams Cheddar or Gruyere cheese (Grated)

Instructions
 

Prep

  • Peel and cut the onions in half and slice into half-moon onion rings
  • Mince or finely chop 3 cloves of the garlic
  • Weigh/ measure the other ingredients

To Make

  • In a large pot over a medium heat warm the oil and add the onions. Add a pinch of salt, cover and cook for 5 minutes stirring frequently
  • Reduce the heat to low. Add the butter, stir till melted then cook slowly for 20-25 minutes, stirring frequently. The onions should be caramelised and golden brown but definitely not burned
  • Add the sugar and garlic and stir for 2 minutes
  • Add the wine/ lager or stout and scrape the pan to deglaze. Allow it to mostly evaporate then add the stock. Bring to a low simmer and add the herbs. Mix well, partly cover and cook for 30 minutes.
  • Pre heat the oven to 200℃
  • 15 minutes from the end of the cooking time drizzle both sides of the bread with a little olive oil and place in the oven, turning occasionally, until lightly browned
  • Remove from the oven and rub both sides with the remaining garlic clove cut in half
  • Pile the cheese high and evenly over the toast and place back in the oven until melty

To Serve

  • Serve in warmed soup bowls and place one of your cheesy toasts on top of each
  • Garnish with chopped parsley if you so wish
