Turn your leftover crust into deliciously crispy and sweet Rusk!



If using crust:

  • 8 pieces of bread crust, cut into 6 pieces
  • 45 tsp butter (depending on amount of crust)
  • 1 1/2 tbsp sugar

If using whole slices:

  • 2 slices of bread
  • 45 tsp butter (depending on size of bread)
  • 2 tbsp sugar
  • cut into 16 pieces


Over the stove:

  1. Over low heat, add the bread to a pan and toast until light golden brown.
  2. Turn off the heat and add the butter.
  3. Once melted, add the bread and toss in the butter. Turn heat on to low and then let it toast up until golden brown.
  4. Shake the pan as needed to prevent burning.
  5. Turn off the heat and then add sugar and shake the pan to coat all the pieces. Serve and enjoy!

Toaster oven:

  1. Place the bread in a toaster oven tray and bake for 1 – 1/2 minutes until light brown.

  1. Just made this with the leftover (vegan) shokupan I had that. It was so simple to make on the stovetop, and it definitely revived my stale bread into a tasty weekend treat!
