A creamy, cheesy dip featuring caramelized Vidalia onions baked with Parmesan and Gruyère cheeses, perfect for gatherings and quick snacks.
Caramelize onions slowly over low heat to avoid burning. Let the dip rest after baking to thicken and enhance flavors. Use high-quality Parmesan (Parmigiano-Reggiano) and creamy Gruyère for best results. Can be made a day ahead by caramelizing onions and mixing the base, then baking fresh before serving.
