Portobello Cheeseburger With Sweet Onion Relish Recipes

GRILLED PORTOBELLO BURGER WITH ONION JAM

Steps:

• Put the yogurt in a paper towel-lined strainer set over a bowl, set aside to drain and thickened, about 60 minutes. Discard the watery liquid. Whisk the horseradish into the thickened yogurt.
• Meanwhile, heat 2 tablespoons of the olive oil in a medium skillet, over medium heat. Add the onions, 1 thyme sprig, and season with salt and pepper, to taste. Cook, covered, until the onions have wilted, about 10 to 15 minutes, (give them a stir every now and then with a wooden spoon to prevent them from sticking). Add the red wine, and simmer over high heat until most of the wine gets absorbed into the onions. Add the honey and red wine vinegar and simmer gently until the onions get jam-like, about, about 15 minutes.
• Preheat a stove top grill pan over medium-high heat. Whisk the remaining 2 tablespoons oil, garlic, and balsamic vinegar in a bowl. Strip and add the leaves from the remaining sprig of thyme. Coat the mushroom caps all over with the flavored olive oil. Grill the mushrooms, turning as needed, until tender but not mushy about 3 to 4 minutes per side. Season with the salt and pepper.
• Sandwich the mushroom between the buns, top with some of the onion jam, some lettuce, and a dollop of the horseradish cream. Serve warm.

FRENCH ONION PORTOBELLO BURGERS

Steps:

• Preheat the broiler. Line a rimmed baking sheet with aluminum foil.
• Melt the butter in a medium skillet over medium-low heat. Add the sliced onions, 1 tablespoon fresh thyme or 1 1/2 teaspoons dried, 1/2 teaspoon kosher salt and a few grinds of pepper. Cook, stirring occasionally, until the onions are deep golden brown and caramelized, about 15 minutes. If the skillet gets too brown, add 2 tablespoons water and scrape the brown bits from the bottom of the skillet with a wooden spoon; continue to cook until all the water has evaporated. Add 1 tablespoon of the Worcestershire and stir until completely absorbed, about 1 minute more.
• Meanwhile, place the muffins or buns on the prepared baking sheet and broil until toasted and browned along the edges, 1 to 2 minutes. Set aside for serving.
• Put the mushroom caps, gill-side up, on the same baking sheet. Broil until they release their juices and soften slightly, about 6 minutes. Flip the mushrooms, brush the tops with the oil and season with the garlic salt. Broil until lightly browned and the juices have cooked off, about 6 minutes more. Top each mushroom with 1/4 cup cheese, then return to the broiler until the cheese melts, 1 to 1 1/2 minutes.
• While the mushrooms are broiling, stir together the mayonnaise, garlic, remaining 1 teaspoon fresh thyme or 1/2 teaspoon dried thyme and 1 teaspoon Worcestershire in a small bowl until smooth. Season with a pinch of kosher salt and pepper. Spread on the inside of the toasted muffin or bun tops. Place 1 portobello mushroom on each muffin or bun bottom. Layer with the caramelized onions and crispy fried onions, then close the burgers and serve.
