A rich and comforting baked dip combining sweet Vidalia onions and nutty Gruyère cheese, perfect for party snacks with crispy crostini.
Caramelize onions slowly over medium-low heat to bring out sweetness. Use day-old baguette for crispier crostini. Let cream cheese soften at room temperature for smooth mixing. For a lighter dip, substitute sour cream with plain Greek yogurt. To speed caramelization, add a pinch of baking soda but classic slow cooking yields best flavor.
