Mushroom steak sandwich

This is the perfect dish for the arch carnivore! We use a lionsmane mushroom which has been associated with improved brain function, and so many other positive health benefits and it tastes amazing and provides a really “meaty” texture. If you cant get lionsmane you could easily use portabello mushrooms instead.

Takes 35 minutes

Serves 2


  • Ingredients:
  • 300 g 10.5 oz lion’s mane mushrooms
  • 1 x large Baguette
  • 50 g 1.75 oz Lettuce of choice
  • 4 tbsp vegan Mayo
  • 4 tbsp lovely basil pesto or pesto of choice
  • 3 small gherkins
  • Marinade
  • 100 ml beetroot juice
  • 4 tbsp tamari/ soy sauce
  • 1 tbsp smoked paprika
  • 2 tbsp maple syrup
  • 3 tbsp olive oil
  • 1 tbsp apple cider vinegar
  • pinch salt
  • 1 tsp ground garlic powder
  • Pinch black pepper


  • Method:
  • Cook the mushrooms down
  • Heat a wide bottomed non-stick pan on high heat and once hot add 1 tbsp of oil.
  • Add the mushrooms, along with a good pinch of salt and fry them on each side for 5 mins. Use a smaller lid to press them down until they reach a height of approx 2cm. There will be a bit of sizzle as the water from the mushrooms reacts with the oil so just be careful here. Once the mushrooms are slightly golden on each side remove them from the pan and turn the heat off.
  • Marinade the mushrooms
  • Mix together the ingredients for the marinade and in a bowl or baking tray marinade the mushrooms in the marinade ensuring that all the mushrooms are well coated. You can leave them to marinade overnight or for 20 mins. The longer you leave them soak the pinker and more flavourful they will be.
  • Cook the marinaded mushrooms and slice
  • Heat the frying pan on high heat and add 1 tbsp of oil, remove the mushrooms from the marinade and fry them until they go a lovely charred colour on each side. This should take approx 2 mins on each side. See the picture below as a reference.
  • Remove the cooked mushrooms from the pan and slice them into 1cm thick slices.
  • Build you sandwich
  • Cut the baguette in half lengthwise. Add the mayo to the bottom and the pesto to the top. Slice the tomatoes and the gherkins. Add the lettuce ontop of the mayo, followed by the tomatoes and the gherkins. Finally add a generous amount of the mushrooms steak. Put the top on and cut in the half for 2 amazing sandwiches!
