INGREDIENTS
2 onions, sliced thinly
6 tbsp butter
4 thick slices of sturdy white bread
120 g Comté or Gruyère, sliced
Salt and pepper
Ah, that feels good. Do you remember we discussed that letting onions caramelize for a long time is really a super good idea? Especially when you then put them in such an incredibly delicious French melt; a toast with sweet soft brown caramelized onions where that divinely good Comté or Gruyère just drips out, hmmmm…
Here's how to make the French melt
- Heat 3 tablespoons of butter in a large non-stick frying pan or a cast-iron skillet over medium heat.
- Add the onions when the butter has melted, sprinkle with salt and pepper, and cook for about 45 minutes until dark golden brown while stirring regularly with a (wooden) spatula.
- If they seem to be burning, stir in 1 tablespoon of water occasionally.
- Put the onions in a bowl and wipe the pan with some kitchen paper.
- Put the pan back on the heat and melt another tablespoon of butter in it.
- Place the slices of bread in the pan and gently move them around (without flipping) until they are lightly golden brown after about 2 minutes.
- Remove the slices of bread from the pan and place them with the cooked side facing up on a cutting board.
- Spread half of the cheese over 2 toasted sides, then all the onion rings, and then the rest of the cheese.
- Now place the 2 other slices with the cooked side on the cheese/onion slices and press down a bit. You now have 2 sandwiches with the outer sides uncooked.
- Melt another 1 tbsp of butter in the pan and place the toasts in it.
- Cook them for about 3 minutes on one side while gently moving the pan a bit to distribute the butter.
- Add the last tablespoon of butter, flip the sandwiches over, and repeat.
- Serve immediately.
