For the marinated portobello:

  • 2 large portobello mushrooms
  • 6 tbsp soy sauce or tamari for gluten-free
  • 4 tbsp rice vinegar
  • 3 tbsp maple syrup or agave nectar
  • 3 tsp sesame oil

For the sweet and spicy mayo:

  • 1/2 cup vegan mayo
  • 1-2 tbsp sriracha sauce or to taste
  • 1 tsp soy sauce or tamari for gluten-free

To build the bowls:

  • cooked brown rice enough for 2
  • frozen edamame shelled and thawed
  • cucumber sliced
  • carrots peeled and julienned or grated
  • seaweed crumbled or sliced
  • red onions thinly sliced
  • radishes thinly sliced
  • pickled ginger
  • sesame seeds


To make the portobello:

  • Remove the stems from the portobello mushrooms. Then, cut them in cubes of about 1 1/2 inches.
  • In a large bowl, mix all the marinade ingredients together. Then add the portobello cubes and gently incorporate them in the sauce. Let sit for 10 minutes.
  • Pre-heat the oven at 400°. Line a baking sheet with parchment paper.
  • Take the portobello cubes with a spoon leaving the extra marinade in the bowl and distribute them on the parchment paper so the cubes don't touch each other. Keep the remaining marinade sauce aside for drizzling on the bowl.
  • Cook in the oven for 15 minutes.

To make the spicy mayo:

  • In a medium bowl, combine all the ingredients together. Adjust the amount of sriracha depending of how spicy you want the mayo to be. Keep in the fridge until ready to eat.

To build the bowls:

  • Divide the cooked brown rice within 2 bowls. Then, top with the rest of the garnishes. Add the portobello mushroom cubes. Finally, add some more of the remaining marinade sauce and drizzle with the spicy mayo. Sprinkle with sesame seeds if desired. Enjoy!


There is a lot of variations possible for the garnishes! Try adding avocado, seaweed salad, fruits (mango, oranges or pineapple), green onions or bean sprout.
