The Best Grilled Portobello Mushroom Burger Recipes

Steps:

• Clean mushrooms and remove stems, reserve for other use. Place caps on a plate with the gills up.
• In a small bowl, combine the oil, onion, garlic and vinegar. Pour mixture evenly over the mushroom caps and let stand for 1 hour.
• Grill over hot grill for 10 minutes. Serve immediately.

Steps:

• Put the olive oil and balsamic vinegar in a pitcher. Add the basil, parsley, thyme, salt and pepper and whisk together. Pour the mixture into a resealable plastic bag. Add the mushrooms, seal the bag and toss around to coat. Grill immediately, or leave the mushrooms in the marinade for up to 2 hours.
• When ready to cook, heat a grill or grill pan to medium high. Cook the mushrooms until lightly charred and tender, 4 to 5 minutes per side. Toast the buns cut-side down until golden, a couple of minutes.
• Serve the mushrooms in the buns with sliced tomato, red onion, butter lettuce, mustard, mayonnaise and ketchup.

Steps:

• Place the mushroom caps, smooth side up, in a shallow dish. In a small bowl, whisk together vinegar, oil, basil, oregano, garlic, salt, and pepper. Pour over the mushrooms. Let stand at room temperature for 15 minutes or so, turning twice.
• Preheat grill for medium-high heat.
• Brush grate with oil. Place mushrooms on the grill, reserving marinade for basting. Grill for 5 to 8 minutes on each side, or until tender. Brush with marinade frequently. Top with cheese during the last 2 minutes of grilling.
