Best 5 Caramelized Onion Grilled Cheese Gruyere Recipes

GRILLED CHEESE WITH CARAMELIZED ONIONS

Steps:

• Heat the canola oil and 1 tablespoon butter in a large saute pan over medium heat. When the butter is melted, add the onions and cook, stirring occasionally, until dark brown and caramelized, about 25 minutes. Add the vinegar, sugar and 2 tablespoons water, scrapping up any dark bits that have accumulated on the bottom of the pan. Continue to cook until all the liquid has evaporated. Transfer the onions to a bowl and reserve.
• Butter 1 side of each bread slice. Lay 6 slices butter-side down on a work surface. Top each with 2 slices of Gruyere, a dollop of the onions and 2 more slices of Gruyere. Top with another slice of bread, butter-side up.
• Heat a cast-iron griddle over medium heat. Add the sandwiches and cook until the cheese begins to melt and the bread is golden brown, 2 to 4 minutes. Flip and continue to cook until golden brown and the cheese is melted through, 2 to 4 minutes. Cut in half and serve immediately.

CARAMELIZED ONION GRILLED CHEESE

Steps:

• Heat 1 tablespoon butter in a medium skillet over medium heat. Add the onions and sprinkle with the thyme, 1/2 teaspoon salt and several grinds of pepper. Cook, stirring occasionally, until the onions are browned and tender, about 20 minutes. Turn off the heat and stir in 1 tablespoon of the Dijon mustard and 1 tablespoon water to coat the onions. Transfer to a bowl and set aside.
• Heat a griddle over medium heat.
• Buzz the Cheddar, Gruyere, Robiola, prosecco, parsley, garlic and remaining 1 teaspoon Dijon mustard in a food processor until combined but still chunky and spreadable. Evenly spread the cheese mixture over one side of each slice of bread. Top 2 slices with the onion mixture and then sandwich the onions with the other 2 slices, cheese-side in. Spread the remaining butter on the outside of each sandwich and season with salt and pepper. Griddle the sandwiches over medium heat until golden brown on the first side, about 5 minutes. Flip and continue to cook until the cheese is melted and the exteriors are crispy, about 5 minutes more.

SWEET AND SPICY CARAMELIZED ONION & BBQ GRILLED CHEESE

Steps:

• Melt 1 tbsp of butter in a skillet over medium heat. Add the sliced red onion and stir occasionally until color changes to slightly brown and taste is sweet, about 10-15 minutes. Remove onions from skillet and set aside.
• Spread 1 tablespoon of the remaining butter onto one side of each slice of bread.
• Divide barbecue sauce evenly among 4 of the slices and spread evenly opposite the butter side. Lay cheddar cheese on top of sauce. Divide caramelized onion among the sandwiches, then top with pepper jack. Finish assembly by placing remaining bread slices on top. The butter sides of the bread should both be on the outside of the sandwiches.
• Place 2 sandwiches in the skillet and cook sandwiches two at a time, flipping when bread is golden brown on one side and cheese begins to melt. If cheese is not melting quickly enough, place a lid over the pan or use a heavy skillet to place on top and press the sandwiches down.

GRILLED SAUSAGE SANDWICHES WITH CARAMELIZED ONIONS AND GRUYèRE CHEESE

Steps:

• Heat 2 tablespoons oil in heavy large skillet over medium-high heat. Add onions and sauté until slightly softened, about 5 minutes. Stir in vinegar, sugar and caraway seeds. Reduce heat to medium-low and sauté until onions are deep brown and very tender, about 20 minutes longer. Season to taste with salt and pepper. (Can be prepared 2 hours ahead. Let stand at room temperature. Rewarm over low heat before using.)
• Preheat broiler. Brush 11x7-inch metal baking pan with oil. Place sausages in pan. Broil until sausages are brown and crisp, about 6 minutes per side. Transfer sausages to work surface and cut lengthwise in half.
• Arrange 3 sausage halves on each of 2 bread slices. Spread 2 teaspoons mustard over sausages on each. Top sausages with caramelized onions, dividing equally. Top with Gruyère or Emmenthal cheese slices, dividing equally. Cover with remaining 2 bread slices. Spread half of butter over upper bread slices.
• Heat large nonstick skillet over medium-low heat. Carefully invert sandwiches, buttered side down, into skillet. Cover and cook until bottoms are brown, about 5 minutes. Spread remaining butter over upper bread slices. Turn sandwiches, cover and cook until bottoms are brown, about 4 minutes longer.

FRENCH ONION GRILLED CHEESE

Steps:

• In a large skillet over medium-high heat, melt 2 tablespoons butter. Add the onions and season with salt and pepper. Cover and cook, stirring once or twice, until the onions are softened, 3 to 5 minutes. Uncover, reduce the heat to medium-low, and cook, stirring occasionally, until deep golden brown, 20 to 25 minutes. If the onions look dry or like they might burn, add a few tablespoons of water at a time, scraping up any browned bits that are stuck to the bottom of the skillet. If desired, once the onions are done, deglaze the skillet with vinegar and cook until the liquid has evaporated, about 1 minute. Transfer the onions to a medium bowl and season to taste with salt and pepper. Wipe out the skillet, or wash it, if necessary.
• Add the cheese to the onions and stir to combine. Put down two slices of bread, and scoop half of the cheese-onion mixture onto each one. Top with the remaining slices of bread, and press down gently.
• In the skillet, melt 1 tablespoon butter over medium heat. Add the sandwiches and cook until the bottoms turn golden brown, 3 to 4 minutes, reducing the heat to prevent toast from darkening too quickly, if needed. Add the remaining 1 tablespoon butter, flip the sandwiches, press down and cook until the cheese has fully melted and the bottoms turn golden brown, 3 to 4 minutes. Serve immediately.
