Portobello Mushroom Cheeseburgers Recipes

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:

• Preheat the oven to 425 degrees F. Line 2 rimmed baking sheets with parchment and set aside.
• Roast the mushrooms: Arrange the mushrooms, stem side up, onions and garlic cloves in a single layer on 1 prepared baking sheet. Drizzle with half of the olive oil. Drizzle 1/2 cup water around the mushrooms on the baking sheet. Season generously with salt and pepper. Roast in the center of the oven until the mushrooms shrink in size and become darker brown, 15 to 18 minutes. Remove and let cool.
• Bread the mushrooms: In a medium bowl, whisk the eggs with a splash of water. In another medium bowl, combine the breadcrumbs with the granulated garlic. Dip each mushroom in the egg mixture and then coat completely with the breadcrumbs. Reserve everything.
• Fry the mushrooms: In a large skillet, heat the remaining olive oil over medium heat until it begins to smoke. Add the mushrooms in a single layer. Cook on one side until golden brown, 2 to 3 minutes. Flip and cook on the second side until golden brown, another 2 to 3 minutes. Remove the mushrooms from the oil and arrange in a single layer on a clean baking sheet. Season with salt and pepper.
• Make the filling: In a medium bowl, combine the roasted garlic cloves and onion slices with the cheese. Add any remaining egg and 1/4 cup of the breadcrumbs leftover from the breading. Add the basil and mix well.
• Assemble and bake: On the same baking sheet, place 2 portobellos, stem-side up, with some distance between them. Pile half of the filling on each and then top with the remaining mushrooms, pressing gently but firmly down, so it forms a fairly compact sandwich. Bake until the cheese melts, 6 to 8 minutes.
• Arrange the lettuce to form 2 cups. Drizzle some pickle juice and red wine vinegar into the cups. Season with salt and pepper and then top with some sliced pickles.
• Place each mushroom burger onto a bottom bun. Flip a lettuce cup onto each burger and top with the top bun. Serve.

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:

• 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.
