This recipe creates a classic French Onion Dip by slow-caramelizing Vidalia onions and shallots until deeply flavored. These sweet, savory onions are then chopped and folded into a creamy base of sour cream and mayonnaise with seasonings. The dip requires chilling to allow the flavors to meld before serving with chips or vegetables.

Patience is crucial for achieving the deep, rich flavor of properly caramelized onions and shallots; cook them low and slow until truly dark brown. Ensure the caramelized mixture cools completely before folding it into the dairy base to prevent separation or a watery dip. Chilling the dip for at least an hour, or preferably overnight, allows the flavors to meld and deepen significantly. For an extra layer of complexity, you could add a splash of sherry or balsamic vinegar during the last few minutes of caramelization.
