Portobello Mushroom Cheeseburgers Recipes

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:

• 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.

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:

• For the burgers: In a shallow baking dish, use a whisk to combine the lemon juice, olive oil, Worcestershire, thyme, and garlic powder. Place mushrooms in the marinade, cover, and refrigerate for at least 1 hour. Turn over the mushrooms, cover again, and refrigerate at least another hour. (Mushrooms can marinate for several hours.)
• For the onions: In the meantime, make the onions. In a skillet, heat the olive oil over medium heat. Add the onions and cook about 5 minutes, stirring occasionally. Add the water, cover, and reduce heat to low. Cook 20 to 30 minutes, stirring occasionally, until the onions are golden brown. Remove the pan from the heat. Season the onions with salt and pepper. Set aside.
• For the aioli: Combine all ingredients in a small bowl. Refrigerate until serving time.
• To finish the burgers: Preheat oven to 450 degrees F. Remove mushrooms from marinade and season with salt and pepper on both sides. Place the mushrooms on a baking sheet, gill sides up. Bake for 5 minutes. Remove from the oven and arrange cheese and caramelized onions on the gills of each mushroom and bake another 5 minutes, until the cheese is melted and bubbly. Place 1 mushroom on each muffin and garnish with aioli and arugula. Serve immediately.

Steps:

• 1. Lay the mushrooms on a greased baking sheet, gill sides up. Whisk together the garlic, sherry, 2 tablespoons of the oil and 2 teaspoons of the salt. Pour the mixture over the mushrooms. Marinate for at least 30 minutes or up to 2 hours.
• 2. Preheat the oven to 400 degrees F. Divide the cheese evenly among the mushroom caps. Roast until the mushrooms are fork-tender and the cheese is melted, 15 to 20 minutes. Reserve any cooking juices in the pan.
• 3. Meanwhile, heat the remaining 3 tablespoons olive oil in a large skillet over high heat. Add the onions and cook until charred and tender, stirring often, about 10 minutes. Add the spinach and the cooking juices from the mushrooms. Cook until just the spinach is wilted. Season with the remaining 1/2 teaspoon salt.

Grill cut side of hamburger buns until light golden, about 2 minutes.
