Truffle Mayo:

The Burger:

  • Portobello mushrooms, seasoned with rosemary, thyme, garlic, olive oil 20.0 slices
  • Poppy seed buns 10.0 pc
  • Onions, caramelized 280.0 g
  • Watercress 100.0 g

This gourmet burger is unashamedly rich and delicious. We’ve gone big on the truffle flavours here. Next to the rosemary and thyme mushroom, this dish is a real umami hit. We think this would go perfectly with some sweet potato fries, or if you really want to deliver, why not add truffle fries with vegan cheese?



  1. Truffle Mayo:

    • Add the Hellmann's Vegan Mayonnaise into a bowl.

    • Season to taste.
  2. The Burger:

    • Grill mushrooms until they’re cooked through and nicely charred on both sides.
    • Slice the buns and brush with oil. Toast on the grill.
