CARAMELIZED ONION 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:

• Cut the onions in half and then slice them into 1/8-inch thick half-rounds. (You will have about 3 cups of onions.) Heat the butter and oil in a large saute pan over medium heat. Add the onions, cayenne, salt, and pepper and saute for 10 minutes. Reduce the heat to medium-low and cook, stirring occasionally, for 20 more minutes until the onions are browned and caramelized. Allow the onions to cool.
• Place the cream cheese, sour cream and mayonnaise in the bowl of an electric mixer fitted with the paddle attachment and beat until smooth. Add the onions and mix well. Taste for seasonings. Serve at room temperature.
