Ultimate Henderson’s Cheese Toastie

Ultimate Henderson’s Cheese Toastie

We’ve taken the cheese toastie to a whole new level, with the help of Henderson’s Relish and some ridiculously gooey vegan cheese.

If this recipe ‘pulls’ on your heart strings, grab yourself a bottle of Henderson’s Relish – available in UK supermarkets or online for global shipping – and give it a try yourself!


Before you start

Small saucepan with a lid on a medium heat | Frying pan | Line a tray with kitchen paper | Sandwich iron or heavy pan that will fit inside the frying pan


For the toast

  • 2 thick slices of sourdough bread
  • 3 tbsp soft plant-based butter
  • 1 tsp Henderson’s Relish

For the cheese sauce

  • 1 tbsp plant-based butter
  • 1 tbsp plant-based cream cheese
  • 60g smoked plant-based cheese
  • 1 tbsp Dijon mustard
  • 1 tsp plant-based milk
  • 1 tbsp Henderson’s Relish
  • Pinch of salt

For the caramelised red onions

  • 2 large red onions
  • 1 tbsp olive oil
  • 1 tbsp Henderson’s Relish
  • 1 tsp balsamic vinegar
  • 1 tsp soft brown sugar
  • Pinch of salt


  1. 1.

    Start with the caramelised onions | Peel and thinly slice the onions | Drizzle some olive oil in the small saucepan over a medium heat | Once warm, add the sliced onions to the pan along with the balsamic vinegar, Henderson’s Relish, sugar and salt | Stir, reduce the heat to the lowest setting and put the lid on the pan | Cook until soft and gooey.

  2. 2.

    Meanwhile, make the smoked cheese mix | Place the plant-based butter in a small saucepan over a low heat | Once melted, add the cream cheese, grated cheese, mustard, milk, Henderson’s Relish and a pinch of salt | Mix well until everything comes together and cook on a low heat until the cheese sauce becomes stringy and cheesy.

  3. 3.

    Make the butter | In a small bowl, mix together the butter and Henderson’s relish until it comes together.

  4. 4.

    Finish the sandwich | Put a frying pan over a medium heat and add the Henderson’s butter, ensuring it coats the base of the pan evenly | Lay 2 slices of bread in the pan | Spoon the caramelised onions on top of one slice of bread before topping with the cheese sauce | Lay the remaining bread slices on top.

  5. 5.

    Use your biggest, heaviest pan or a sandwich iron to compress the sandwiches | Fry for 3–4 minutes, then remove the weight, very carefully flip the sandwiches over and replace the weight on top | Fry for another 3–4 minutes | Remove the sandwiches to a wooden board, cut in half and serve.
