Reuben Portobello Mushroom Burgers Recipes

Steps:

• In a large bowl, combine the first 9 ingredients. Shape into four 3/4-in.-thick patties., In a large cast-iron or other heavy skillet, heat oil over medium heat. Add burgers; cook until crisp and lightly browned, 3-4 minutes on each side. Serve on buns with lettuce and if desired, tomato and mayonnaise.

Steps:

• Whisk together the vinegar, salt, pepper, garlic and olive oil. Toss with the mushroom caps in a wide bowl. Rub the marinade over the tops of the mushroom caps and place them on a baking sheet, rounded side up. Let sit for 15 minutes. Don't rinse the bowl, because you'll use any oil and vinegar residue to dress the spinach.
• Bring a large pot of water to a boil, salt generously and blanch the spinach for 20 seconds. Transfer to a bowl of ice water, drain and squeeze dry. Chop coarsely and toss in the bowl with the residue of the marinade. Set aside.
• Prepare a medium-hot grill, heat a heavy skillet over medium-high heat, or preheat an electric grill or panini pan on medium-high. Season the mushrooms as desired with salt and pepper. Place the mushrooms on the hot grill or pan, rounded side down. Cook them for about 6 to 8 minutes, depending on the thickness, until lightly browned, and moist. Turn over and cook for another 6 minutes. Turn over for a minute to reheat the top, then flip back over and place the cheese on top. Continue to cook until the cheese melts. If using a panini grill, cook 6 to 8 minutes. Open the grill and place the cheese on top. Wait for it to melt. Place a mound of spinach on the bottom half of each hamburger bun and place the mushrooms, rounded side up, on top of the spinach. Top with your choice of condiments and serve.

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.

Steps:

• Rub the mushroom caps with a damp cloth to clean. Remove stems and reserve for Round 2 recipe "Stuffed Zucchini".
• In a small bowl combine the grill seasoning, oil, garlic, Worcestershire sauce and vinegar. Brush over the mushrooms making sure to coat completely. Reserve 2 tablespoons of the marinade for the aioli.
• Heat a grill pan or outdoor grill on medium heat. Put the mushrooms, gill side down, onto the grill and grill about 4 to 5 minutes on each side. After you flip the mushrooms top each with 2 tablespoons of Cheddar.
• While the mushrooms are grilling, make the aioli sauce by combining the remaining 2 tablespoons of the marinade with the mayonnaise in a small bowl. Spread each hamburger bun with aioli sauce. Remove mushrooms from the grill and serve on the toasted buns with lettuce and tomato slices.

Steps:

• Preheat grill for medium-high heat and lightly oil the grate.
• Whisk olive oil, balsamic vinegar, Dijon mustard, garlic, Worcestershire sauce, salt, and pepper in a bowl. Brush the mixture over the tops and bottoms of the mushrooms; let stand for 10 minutes.
• Grill mushrooms on the preheated grill with the cover closed until mushrooms are browned and tender, about 10 minutes, turning once. Serve on kaiser rolls.
