French Onion Cheeseburger Recipes

Steps:

• Gather ingredients.
• Halve and peel the onions and leave root end attached. Thinly slice the onions from the root end, down and in opposite direction, thinly slicing onion, then slice off the root end to separate.
• To a medium nonstick skillet over medium to medium-high heat, add the oil, 1 turn of the pan. Melt butter into oil, then add onions and season with salt and white or black ground pepper, bay leaf. Stir and soften a few minutes, then add 1/2 cup water and about 1/2 cup consomme or beef bone broth and let it absorb, 4 to 5 minutes. Add creme fraiche or sour cream and mustard, then combine and reduce heat to low/warm, cover. Remove bay before serving.
• Warm the remaining 2 1/2 cups consomme or bone stock in small pot over low heat for dipping.
• Preheat cast-iron skillet or griddle for burgers over medium-high heat.
• Meanwhile, place potatoes in a skillet with lid with 2 1/2 cups water and some butter and bring to boil, covered. Cook 8 to 10 minutes to just tender, then remove lid and let water evaporate. Crush potatoes a bit with the bottom of a water glass and brown to crisp up edges and skins, 6 to 8 minutes. Season with salt and pepper.
• While the potatoes are cooking, mix garlic into the beef. Score meat into 4 sections, then form 4 patties thinner at centers than edges for even cooking. Season the meat with salt and pepper. Cook patties in skillet or on griddle about 8 minutes, turning occasionally. Melt cheese, 2 slices per patty, over tops in last minute or so.
• Split and lightly toast buns, optional.
• Drain and slice some cornichons for the buns.
• Chop parsley.
• To serve: Top bun bottoms with pickles, patties, creamy onions, tops of buns. Cut burgers in half and serve with small bowls of warm consomme or stock for dipping burgers and potatoes alongside, sprinkled with chopped parsley.

Steps:

• For the onion jam: Heat a large saute pan, then toss in the onion and garlic slices with 2 tablespoons oil and a generous pinch of salt. Cook over medium heat for 2 to 3 minutes, then add the Marsala, brown sugar and mustard and cook, stirring occasionally, until the onions are caramelized and tender, 20 to 25 minutes. (Do not rush this step, because properly caramelized onions make this burger top-notch!) Stir in the vinegar and cook to blend in, 1 to 2 minutes. Set aside.
• For the burgers: In a medium bowl, break up the meat and spread it up on the sides of the bowl so that the seasoning really permeates. Sprinkle the meat with salt and pepper. Gently mix in the Marsala, soy sauce and Worcestershire. Do not overmix. (The more you work the meat, the tougher the burger.) Form the meat into 4 even patties that are about 3/4-inch thick and transfer to a baking sheet.
• Use a spoon to gently scoop out a little meat and make a hole or pocket in the center of each patty that does not go all the way through to the bottom. Place about 1/4 cup Gruyere in the hole of each patty. Flatten the piece of meat you scooped out and press it over the cheese so that it's hidden in the middle of the patty. Turn the patty on the other side that it is weighing down on the seam. Repeat with the remaining patties. Refrigerate for at least 30 minutes and up to 6 hours.
• Preheat the oven to 400 degrees F.
• Heat a large skillet over medium-high heat and add the remaining 4 tablespoons oil. Sprinkle the patties lightly with salt. When the oil begins to smoke lightly, arrange the patties in a single layer, cheese-pocket-side down, at a distance from one another. Cook the patties, undisturbed, until the bottom browns, 3 to 5 minutes. Turn the patties on their other sides and let the bottoms brown again, 3 to 5 minutes. Lower the heat and add the stock to the skillet and cover. Cook on low heat until the patties are cooked through, 8 to 10 additional minutes. Remove the cover, shut off the heat under the skillet and let the patties rest with the heat off.
• Arrange the bun halves in a single layer on a baking sheet and sprinkle each bun half with about 1/4 cup Gruyere. Place the baking sheet in the center of the oven and toast until the buns are golden brown and the cheese is bubbling and melted, 5 to 8 minutes. Season with salt and pepper.
• Arrange the bun bottoms on a flat surface. Mix the onion jam and remaining cup Gruyere into the liquid in the skillet. Taste for seasoning. Spoon some of the onions and liquid on each bun bottom and top with the patties and more onions. Top with a few slices of pickle and season the bun tops with a pinch of salt. Close the burgers and serve.

Steps:

• Mix together the patty ingredients until evenly combined.
• Form the beef into a round patty.
• Repeat with the remaining beef.
• Heat oil in a pan over medium heat.
• Cook the burgers for 3 minutes on the first side, flip, and place the slice of comté on top.
• Cook for 6 more minutes.
• Assemble the burgers on the buns with caramelized onions and arugula.
• Enjoy!

Steps:

• Heat the olive oil in a large skillet over medium-high heat. Add the onion and cook, stirring, until it starts to brown, 3 to 4 minutes. Add the sugar and 1/2 teaspoon salt, reduce the heat to medium low and cook, stirring occasionally, until deep golden, 15 more minutes. Add the chicken broth and 1 teaspoon Worcestershire sauce and simmer until the onion is tender and the liquid is almost evaporated, 8 minutes.
• Preheat the broiler. Mix the beef, onion powder and the remaining 2 tablespoons Worcestershire sauce in a bowl with your hands. Form into four 3/4-inch-thick patties and place on a broiler pan. Make an indentation in the center of each with your thumb; season the patties with salt. Broil, turning once, 5 minutes.
• Place the buns cut-side up on a baking sheet. Sprinkle with both cheeses and broil until melted, about 1 minute. Spread mustard on the buns; sandwich with lettuce, the burgers and caramelized onion. Serve with potato chips.

Steps:

• In a large bowl, combine the mushrooms, onions, Worcestershire sauce and salt. Crumble beef over mixture and mix well. Shape into four patties. , Grill, uncovered, over medium heat or broil 4 in. from the heat for 6-9 minutes on each side or a until a thermometer reads 160° and juices run clear. Serve on buns with lettuce and tomato.
