Portobello Mushroom Burger

Grilled Portabello Mushroom Burgers

The texture of the mushrooms offers a meatiness that truly satisfies, and can hold up to a generous bun and flavorful pesto. You can always use peppers from a jar, but if you've never roasted your own, it’s worth a go. When the burgers are grilled and tucked between the focaccia along with all of the other goodies, they look just as compelling as any meaty number.

Ingredients

  • 4 large portabello mushrooms, stems removed, washed
  • 1 tablespoon extra-virgin olive oil
  • 2 teaspoons balsamic vinegar
  • Salt
  • Freshly ground black pepper to taste
  • 4 generous slices Mozzarella cheese
  • 1 loaf focaccia bread, cut into 4 burger-sized squares and split down the center
  • Prepared basil pesto
  • 2 small roasted red or yellow bell peppers, split in half*
  • 1 large handful baby arugula or spinach
  • 4 large slices tomato (more if tomatoes are small)

Instructions

  1. Heat up the grill to medium-high or turn on the oven broiler with the rack at the highest level. While the grill./broiler are heating, drizzle the oil and vinegar over the mushroom caps and rub all over with your hands. Season liberally with salt and pepper.

  2. Put the mushrooms, cap-side-down, on the hot grill (set on a baking sheet and put under a broiler, if using). If grilling, cover the grill. Cook until they look quite tender on one side without burning, about 5 minutes. Turn over, cover (if grilling), and cook on the second side for 3 to 5 minutes until tender but not shriveled. For the last minute of cooking, set a slice of cheese on each mushroom to melt. Toast the buns on the grill or in the oven.

  3. Remove the buns and mushrooms. Spread a thin layer of pesto on the top and bottom of each bun. Set the mushrooms on each of the bottom buns. Top with the peppers, followed by the tomatoes and arugula or spinach. Serve immediately.

Recipe Notes

*You can find roasted bell peppers sold in jars in most markets or you can roast your own (a quick Google search will turn up plenty of instructions).
