Croque Monsieur Bake

I made this on day four of isolation, and I bought this loaf of sourdough two days before isolation started. It had turned into a solid block that required quite a lot of brute strength to soar through with my bread knife! I remembered this recipe from Nigella Lawson that would breathe new life into my stale loaf of bread. Coupled with the leftover ham and some random bits in the fridge it was a true victory moment in quarantine cuisine. 

Essentially to save stale bread other than using this method to restore it back to a soft loaf, one of the tastiest things to do is a french toast style treatment by soaking the bread in milk with beaten eggs. It worked perfectly for this dish as it pairs nicely with the melted cheese. 

Back in 2011 when the Airfyer first came out, Philips actually sent me one to review. I loved it and used it quite a lot, however when I moved out of my house a few years ago we decided it had seen better days and got rid of it. Fast forward to last year I decided I needed one in my life again for the times when Ewen travels. Sometimes I just want to heat up a meat pie or something small and warming up our big oven can take SO long. The Airfryer (and this is not a sponsored post!) is essentially a mini fan-forced oven, and takes only a few minutes to heat up. My favourite thing to do in it is day old croissants filled with ham and cheese. So for this meal, I filled the cake baking tray with the croque monsieurs and it was the perfect size for our stale sourdough bread slices. Before too long, we had a delicious brunch ready to devour! 

What’s your favourite thing to do with stale bread?

Print Recipe


  • 6 slices bread
  • 75 g dijon mustard
  • 6 slices Swiss cheese
  • 6 slices ham
  • 6 large eggs
  • ½ tsp salt
  • 80 ml full fat milk
  • 4 tbsp grated Swiss cheese (or cheddar)
  • 1 good sprinkling Worcestershire sauce


  • Spread each slice of bread with mustard. Make sandwiches by putting each slice of cheese against the mustardy bread, and a slice of ham between them. Cut each sandwich in half to make two triangles.
  • Squish the sandwich triangles into an ovenproof dish approx. 27 x 21cm x 6cm deep.
  • Beat together the eggs, salt and milk (I measure out the milk into whatever the mustard’s been in for maximum flavour penetration) and then pour this over the sandwiches tightly packed in the dish.
  • Cover the dish with clingfilm and leave in the fridge overnight (I soaked mine for closer to 2 hours and it was fine).
  • Next morning, preheat the oven to 200°C (180°C fan forced). Take the dish out of the fridge and remove the clingfilm.
  • Sprinkle with the grated cheese and Worcestershire sauce and bake in the oven for 25 minutes.


Based on a recipe by Nigella Lawson
