Portabella Mushroom Burger With Carmelized Onions Recipes

Steps:

• Combine the vinegar,olive oil,basil, oregano,and garlic together. Place mushroom caps smooth side up in a shallow baking dish. Pour marinade over the mushrooms and let stand at room temp. for 15 minutes, turning the mushrooms over 2 or 3 times. The idea is not to drown the mushrooms, only coating them with a thin marinade to add flavor. Do not put them in a zip lock, as they will get soggy. Just brushing the marinade will do.
• To caramelize the onions, take your very thin slices of onion and add them to a frying pan with olive oil. Heating the oil first till it is hot. Then add your pinch of brown sugar, and over a medium low heat, caramelize the onions until they are transparent. I also like to add just a touch of the marinade the mushrooms are marinating in.
• You can grill these mushroom caps (oil the grill first to prevent sticking) or broil them at the lowest position away from heat source. Cook them until the edges just start to brown up (about 3-5 minutes) and then turn them and cook an additional 3-5 minutes. If you broil them, pat them with paper toweling after you remove them form the oven, to prevent them from dripping.
• I like to place a nice slice of cheese on the bun. mozzarella or provolone add much flavor to this. Then place the hot mushroom on top of cheese slice on bun. Then a slice of tomato, a bit of lettuce if you like, your caramelized onions and the alioli. Enjoy!

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.
