These Homemade Portobello Mushroom Burgers are so much better than any restaurant! The secret is a good marinade – overnight! I can’t believe that it’s taken me this long to make homemade portobello mushroom burgers – I LOVE mushrooms!


  • 2-4 large portobello mushroom caps – ( a good 4 inches wide)
  • 1cup balsamic vinegar
  • 2 tablespoons truffled olive oil
  • 1 tsp dried basil
  • 1 tsp  dried oregano
  • 1 tbsp minced fresh garlic
  • buns, lettuce, tomato, etc for topping


  1. Combine all of the marinade ingredients together.
  2. Place the mushrooms gill side up in a lidded container and pour the marinade over them. I find that the marinade soaks in better this way. Marinate for 4-6 hours but best if overnight.
  3. To cook, grill the mushrooms on the BBQ until they are cooked through. Make sure to flip from side to side to cook them evenly and get the moisture out.
  4. Place on toasted buns and top with your toppings of choice.


Using truffle oil is really important – it amps up the mushroom flavour SO incredibly! That’s what makes these soooo good!
