Ingredients

  • 20g butter
  • 2 medium onions, sliced thinly
  • 75g Gruyère or vegetarian alternative, grated coarsely
  • 75g ready-grated mozzarella
  • 4 slices Pain de Campagne or sourdough bread
  • 2 tbsp mayonnaise
  • Marmite, to taste

Step by step

Get ahead
The caramelised onions keep in the fridge for 3-4 days.
  1. Melt the butter in a large nonstick frying pan and gently cook the onions with a large pinch of salt until they’re soft and caramelised, around 30 minutes, stirring often; remove from the heat.
  2. Combine the grated cheeses in a bowl. Spread 2 pieces of bread with mayonnaise, then turn one over and spread with Marmite on the other side. Top with a layer of onions, then the cheese mixture and the second slice of bread, mayo side outwards. Repeat for the second sandwich.
  3. Wipe out the frying pan with kitchen paper then heat up on the hob. Add both sandwiches. Cook over a medium heat for 3-4 minutes each side, weighing the sandwiches down as they cook with something heavy (such as another pan, with a couple of tins of beans inside as extra weight), so that they have maximum heat contact. They should be golden brown, crisp, and molten inside.
