Welsh rarebit is a Welsh dish created with a tasty, thick sauce, poured over toasted bread. It’s ideal as a traditional delicacy for celebrating St. David’s Day, and certainly isn’t your average cheese on toast. This simple Welsh Rarebit Toast recipe features a sauce of butter, spring onion, flour, egg, cheese and breadcrumbs - with that special extra ingredient twist, 100 ml of beer!

What you'll need
  • 25g butter
  • 375g mature cheese, grated
  • ½ tsp mustard
  • 100ml milk
  • Some thick-cut bread (3 slices per serving)
  • 6 large tomatoes, sliced (optional)
  • Salt and pepper, to taste

Heat your butter in a pan, until melted. Add the grated cheese and stir, until that, too, is melted.


Pour in your milk and mustard, stirring continuously. Season with salt and pepper.


Boil the mixture, then simmer for another 1 - 2 minutes, before removing from heat.


Toast your bread slices, then layer three pieces with tomato slices (if using) and put on-top of each other. Place on baking parchment on top of a baking tray and pour on some of your rarebit mixture. Grill for 4 - 5 minutes, or until golden brown.

Top-tip: It’s easy to leave out the beer from this recipe. The recipe is still super delicious either way; you could replace it with milk.

If you want to create extra sauce for use later on, the mixture keeps well in the fridge for several days
