Miso-Marinated Portobello Carpaccio (Vegan) Recipe

Combine miso paste, brown sugar, soy sauce, vegetable oil, and lemon juice in a medium bowl and whisk to combine. Rub evenly over surfaces of mushrooms and transfer to a gallon-sized zipper lock bag. Gently press air out from bag, seal, and transfer to refrigerator for at least 1 hour and up to overnight. When ready to proceed, adjust oven rack to center position and preheat oven to 350°F. Remove mushroom caps from bag and wipe off excess marinade with paper towels. Place on a foil-lined rimmed baking sheet gill-side-down and roast until top surface is dry and mushroom is tender throughout, about 30 minutes. Transfer to a cutting board and let rest 5 minutes to cool slightly. Using a very sharp knife, cut mushrooms on a sharp bias into thin slices. Transfer slices to a serving platter or individual platters, fanning them as you go. Drizzle with 1 tablespoon extra-virgin olive oil. Sprinkle with lemon zest, pistachios, black pepper, and coarse sea salt. Toss arugula with remaining 1 teaspoon olive oil, squeezing one of the reserved lemon wedges over the greens. Top mushrooms with arugula and serve, passing remaining wedges tableside.
