French Onion Soup Grilled Cheese Recipe 455

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:

• 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:

• Over a medium-high flame, heat the oil and add the onions. Cook them slowly (make sure the heat is high enough that they don't steam) and allow them to gently caramelize, about 30 minutes. Add salt, pepper, and the butter at the end to season.
• Assemble the sandwich. On a slice of rye, layer cheese, onions, and a second layer of cheese. Cover with the second slice of rye. Place on a panini grill and press. Sandwich is ready when the cheese has melted.
