Roasted Portobello Mushroom Cheeseburgers With Caramelized Onions And Pimento Aioli Recipes

Steps:

• Prepare a grill for medium-high heat.
• Put the onions in a medium bowl and cover with ice water. Let the onions soak 10 minutes while you prep the patties and pimento sauce.
• Combine the beef with 2 tablespoons of the Worcestershire sauce, 1 teaspoon salt and several grinds of black pepper in a medium bowl. Form the meat mixture into eight 3-ounce patties. A quick and easy way to do this is to divide the mixture into 8 piles. Place a pile on top of a deli container lid. Place the top of a second deli container lid against the pile, press down evenly and firmly and watch as a perfect patty forms. Repeat with the remaining meat mixture. Make a slight indentation in the middle of each patty with your thumb to keep the patty from shrinking as it cooks. Set aside.
• Add the cream cheese, pimentos, mayonnaise, cayenne, 1/4 teaspoon salt and the remaining 1 teaspoon Worcestershire to a medium bowl and stir until well combined. Drain the onions and pat dry.
• Lightly brush the grill grates with oil. Grill the patties, indentation-side up, until marked on the bottom, about 3 minutes. Flip and grill until marked on the second side and slightly firm, about 2 minutes more for medium rare. Top each patty with 1 slice cheese, cover the grill and cook until melted, about 1 minute. Remove to a plate and let rest for a few minutes. Toast the buns cut-side down, 1 to 2 minutes.
• Top each bottom bun with 2 burgers. Top the burgers with lettuce and the onions and spread the inside of the top buns with the pimento sauce. Top the burgers with the top buns and secure with a toothpick if desired. Serve with dill pickle and French fries.

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 oven or toaster oven to 425 degrees F (220 degrees C).
• Place mushroom caps, gill side up, on baking sheet. Drizzle with soy sauce and add a few grinds of black pepper to each cap.
• Bake for 25 minutes. Remove from oven, and sprinkle 1 1/2 tablespoon blue cheese onto each cap. Return to oven and bake an additional 10 minutes, or until cheese is fully melted.
