Perfect Bistro Croque Monsieur

  • 200ml milk
  • 20g plain flour
  • 20g butter
  • Salt and pepper
  • 4 slices sourdough bread
  • 1 tbsp dijon mustard
  • 4 slices of quality ham
  • 4 slices of strong cheese, such as gruyere
  • 80g grated mature cheddar
  • Make a quick bechamel sauce by adding the flour and butter to a small saucepan, followed by the milk, whisking continuously to make a creamy white sauce. Simmer lightly for 4-5 minutes, and season well. Set aside.
  • Toast the bread under the grill on one side, then remove, and spread the untoasted side with a generous slick of mustard and bechamel, followed by as much cheese and ham as you fancy. Close the sandwich with another slice of bread, and add a layer of white sauce and plenty of grated cheddar. Bake in the oven for 10 minutes at 220C, and enjoy once it is hot and bubbling. Mmm!
