Portobello Mushroom Burger With Caramelized Onions Recipes

CARAMELIZED ONION AND PORTOBELLO MUSHROOM BURGERS

Steps:

• In a food processor, add black beans, mushrooms, garlic, Worcestershire sauce, water, lemon juice, chia seeds, onion powder, black pepper, salt and harissa. Pulse until mixture is a thick paste; chunks are OK.
• In a large bowl, beat eggs; add mushroom and bean mixture. Then add breadcrumbs, cheese and caramelized onions. Mix well.
• In a large frying pan, heat olive oil over medium heat. Once oil starts to simmer, 1-2 minutes, use dampened hands (the mixture will stick to you if you don't) and scoop a ½cup of mixture into the palm of your hand. Gently shape into a burger, all the while pressing together. The mixture should hold a burger shape. If it doesn't, add a tablespoon more of breadcrumbs.
• Place in frying pan, and cook 3-5 minutes per side, or until they're golden brown and a crust has formed on each side.

ROASTED PORTOBELLO MUSHROOM CHEESEBURGERS WITH CARAMELIZED ONIONS AND PIMENTO AIOLI

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.
