French Onion Grilled Cheese Sandwich Recipes

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.

Steps:

• Melt 2 tablespoons butter in a large skillet over medium-high heat. Add the onion, thyme, onion powder and a pinch of salt and pepper to the skillet and cook, stirring occasionally, until the onions soften and brown, 3 to 4 minutes. Remove the onions to a bowl and leave the skillet on low heat.
• Place one slice of Cheddar and one slice of Swiss on each piece of bread. Top 3 of the slices with the onion mixture, then sandwich with the other cheesed breads, making 3 sandwiches. Spread about 2 tablespoons butter on the tops of the sandwiches, just enough to cover the tops in a thin layer. Melt the remaining 2 tablespoons in the skillet (adding more if it looks dry). Place the sandwiches butter-side up in the skillet. Cook on one side until golden brown, 2 to 3 minutes, then flip and cook the buttered side for another 1 to 2 minutes. Remove from the skillet and cut crosswise into strips-great for dipping in soup! Serve immediately or keep in a warm oven in aluminum foil until ready to use.

Steps:

• Melt 1 tablespoon of the butter in a large sauté pan over medium heat. Add the onion and cook until the slices start to wilt and turn translucent, about 3 minutes. Add the onion soup mix, thyme and 2 tablespoons water. Turn the heat to low, then continue to cook, stirring and adding more water a tablespoon at a time if the mixture gets too dry, until the onions are very soft and golden brown, 5 to 10 more minutes.
• Melt 1 tablespoon butter in a saute pan over medium heat. Spread 1 teaspoon mustard onto one side of each slice of bread. Divide the Cheddar, Gruyere, caramelized onions and crispy onions between 2 of the slices of bread on top of the mustard. Top each with another slice of bread, mustard-side in, and lay the sandwiches in the pan. Cook, pressing down on top of the sandwiches, until the bottoms are golden brown, about 2 minutes. Add the remaining 1 tablespoon butter to the pan and flip the sandwiches, cooking until the cheese is melted and the bottoms are golden brown, about 3 more minutes. Cut in half and serve.

Steps:

• Heat olive oil in a medium skillet over medium heat. Add onion, season with 1/4 teaspoon each salt and pepper, and cook, covered, stirring occasionally, about 5 - 7 minutes. Reduce the heat to medium-low, stir in thyme leaves and cook, uncovered, stirring occasionally, until the onions are golden brown, (add 1 tablespoon water to the skillet if the onions start sticking). Brush one side of each slice of bread with butter or oil. Form sandwiches with the bread, whole-grain mustard, Gruyère cheese, roast beef, and the onion mixture. Cook the sandwiches, covered, until the bread is golden brown and crisp and the cheese has melted, 4 to 5 minutes per side.
