Ingredients

The following ingredients have 4 Servings
  • 4 Portobello Mushrooms (Stems Removed)
  • 1/2 Tbsp Grapeseed Oil
  • 1/4 cup Soy Sauce ((60ml))
  • 1 tsp Paprika
  • 2 Tbsp Maple Syrup
  • 1 Tbsp Light Brown Sugar
  • 2 Tbsp Tomato Paste
  • 1/8 tsp Liquid Smoke
  • 1/2 tsp Oregano
  • 1/2 Tbsp Olive Oil
  • 1 Medium Onion (White, Yellow or Brown, Chopped)
  • 1 Tbsp Soy Sauce
  • 2 Tbsp Maple Syrup
  • Hamburger Rolls
  • Lettuce
  • Tomato
  • Dill Pickles
  • Avocado

Instruction

  • Remove the stems from the portobello mushrooms. 
  • Prepare your marinade by adding soy sauce, paprika, maple syrup, brown sugar, tomato paste, liquid smoke and oregano to a measuring jug. Whisk together until well mixed. 
  • Place the mushrooms on a baking tray or in a shallow dish and brush generously with the marinade on both sides. Leave them to soak in the marinade for 15 minutes.
  • While the mushrooms are marinating, make your caramelized onions. Add chopped onions and olive oil to a frying pan and sauté until the onions are softened. 
  • Add soy sauce and maple syrup and sauté with the onions until sticky and caramelized.
  • Heat up a grill pan and then brush it with 1/2 tablespoon of high smoke oil (we used grapeseed oil). 
  • Add the mushrooms and fry for around 3 minutes each side at medium heat. 
  • Then turn off the heat and brush both sides with marinade. 
  • Serve the portobello burgers on hamburger rolls with lettuce, sliced tomato and sliced dill pickles and topped with the caramelized onions and sliced avocado.
