Caramelized Onion Dip is a classic American appetizer made with slowly cooked onions, cream cheese, sour cream, garlic, and savory seasonings.
The onions are cooked until golden and sweet before being combined with the creamy base, creating a dip that works well for parties, holidays, snack boards, and casual gatherings.
The slow caramelization process develops deep onion flavor, while sour cream and cream cheese create a smooth, rich consistency. Worcestershire sauce, garlic, and fresh parsley add extra savory notes, making this dip a great match for chips, vegetables, sandwiches, and burgers.
