Ingredients
- 20g butter

- 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.
- 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.
- 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.
- 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.
