Preparation Instructions

  1. 1

    Prepare the Miso Mushrooms

    In a bowl, mix the portobello mushrooms with the white miso paste and olive oil. Make sure the mushrooms are evenly coated.

  2. 2

    Grill the Mushrooms

    Preheat the grill to medium-high heat. Grill the marinated mushrooms for about 6-8 minutes on each side, until they are tender and have nice grill marks.

  3. 3

    Cook the Onions

    While the mushrooms are grilling, heat a skillet over medium heat. Add a drizzle of olive oil and the sliced onions. Sauté for about 10-15 minutes, stirring occasionally, until the onions are caramelized.

  4. 4

    Prepare the Black Garlic Aioli

    In a small bowl, combine black garlic (mashed), mayonnaise, lemon juice, salt, and pepper. Mix until smooth.

  5. 5

    Assemble the Burgers

    Toast the burger buns lightly. Spread a generous layer of black garlic aioli on the bottom bun, add the grilled miso mushroom, top with caramelized onions, crumbled goat cheese, and a handful of arugula. Top with the other half of the bun.
