Pineapple Teriyaki Portobello Burger [Vegan, Gluten-Free]

Cook Time



For the Marinade:

  • 1/3 cup tamari
  • 2 teaspoon liquid smoke
  • 2 tablespoons hoisin sauce
  • 1 tablespoon vegan Worcestershire sauce
  • 1/2 cup pineapple juice
  • 1 teaspoon red pepper flakes
  • 2 cloves garlic, minced

For the Toppings:

  • 4 slices pineapple
  • 1/2 cup sliced carrots
  • 1/2 cup sliced cucumbers
  • 1/4 cup rice vinegar
  • 1 tablespoon sesame seeds
  • 1/2 cup vegan mayonnaise
  • 1 tablespoon Sriracha


  • Sliced onions
  • Sliced nappa cabbage
  • 2 buns (gluten-free if necessary)
  • Cilantro
  • 4 Portobello mushrooms


  1. Combine all of the marinade ingredients. Wash and remove mushroom stems. Soak mushrooms in sauce for as long as you can! The longer the better. Combine carrots, cucumber, sesame seeds, and rice vinegar. Let soak.
  2. Heat a grill to high heat. Throw the mushrooms on, cook for 5 minutes on each side. Better to cook less upside down as they become flatter. Throw pineapples on grill, top with excess marinade for extra flavor. Combine vegan mayo and Sriracha.
  3. Assembly: Top buns with Sriracha mayonnaise, mushrooms, cucumber mix, cabbage, and garnish with cilantro. If not ready to eat, wait to assemble as the mushrooms can soak the bread if left for a long time. You can also drain the mushroom over paper towels to mitigate the possibility of a soggy bottom bun.
