Caramelized Onion Grilled Cheese Recipes

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.

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.

• Divide barbecue sauce evenly among 4 of the slices and spread evenly opposite the butter side. Lay cheddar cheese on top of sauce.

The butter sides of the bread should both be on the outside of the sandwiches.
