  • 75 grams of butter
  • 1 tablespoon of vegetable oil
  • 1 kilogram of onions, thinly sliced and halved
  • 10 sprigs of thyme with the leaves picked off
  • 4 cloves of garlic that are thinly sliced
  • 1 teaspoon of caster sugar
  • 1.5 liters of beef stock
  • 2 teaspoons of Bovril (this is an optional ingredient)
  • 4 slices of sourdough
  • 200 grams of grated gruyère
  • A few dashes of Worcestershire sauce


Phase 1

Start by placing a large pan over low heat. Place vegetable oil and butter into the pan and allow the butter to melt and mix in with the oil. Next, add some salt, three-fourths of the thyme, and all of the onions. Cook on low for roughly an hour. Stir regularly. You’ll want the onions to come out very jammy and caramelized. In the last 15 minutes, add sugar and garlic. Throw in the Bovril and beef stock while bringing the entire mixture to a boil. Make sure to season the soup very well at this point. Finish off by simmering the mixture for around 30 minutes. The onions must meld with the rest of the stock.

Phase 2

Make sure the sourdough slices are toasted on both sides. Next, load those slices up with the rest of thyme, the gruyère, and some Worcestershire sauce. Split the mixture between 4 bowls or soup terrines that are ovenproof. Turn up the grill to a high setting and place the pieces of bread on top of the bowls of soup. Be sure to grill the dish for 2 to 3 minutes. You want to see the cheese bubbling.
