Portobello Mushroom Blue Cheese Burgers With Lemon Aioli And Bitter Greens

  • Yield: 4 servings


  • 1/4 cup balsamic vinegar
  • 1/4 cup olive oil
  • 1 tablespoon chopped garlic
  • 1 tablespoon chopped fresh rosemary
  • 4 large fresh portobello mushrooms, wiped clean and stems removed
  • 4 thick Vidalia onion slices
  • Salt
  • Freshly ground black pepper
  • 6 ounces Gorgonzola, thinly sliced
  • 4 large whole wheat hamburger buns or large kaiser rolls
  • Lemon Aioli
  • 1 bunch watercress, rinsed and dried, stems removed


  • In a small bowl, whisk together the vinegar, oil, garlic, and rosemary. Place the mushrooms in a large re-sealable plastic bag, or a baking dish, and cover with the marinade. Marinate for at least 1 hour and up to 2 hours.
  • Prepare the grill.
  • Remove the mushrooms from the marinade and pat dry. Season both sides with salt and pepper, and place gill sides-down on the grill. Cook for 5 minutes, then turn. Arrange the cheese and onion slices on the gills of each mushroom and continue to cook until tender, about 6 to 8 minutes. Open the rolls and lightly toast on the grill, insides down.
  • Place 1 grilled mushroom inside each bun and garnish each, to taste, with aioli. Divide the watercress among the 4 buns and serve immediately.
