Preparation
Step 1
Preheat oven to 425 degrees.
Swirl the olive oil in the pan and add the onions. Cook on low for 20 minutes, sprinkle onions with sugar and cook on low for an additional 45 minutes to one hour. Stir occasionally so they don’t burn.
In a medium bowl, mix mayonnaise, sour cream, bacon, 1 tablespoon chives, salt and pepper until well mixed. Stir in shredded Gruyere and caramelized onions. Place in one quart baking dish, sprinkle 2 tablespoons Gruyere on top and bake for 20 minutes or until bubbly.
Sprinkle with remaining chives and serve warm with crostini or crackers.
