Caramelized Onion Dip — Rich, Creamy, and Full of Flavor 🧅✨

Caramelized onion dip is a classic party favorite because slow-cooked onions become sweet, golden, and deeply flavorful. It is perfect with crackers, chips, toasted bread, vegetables, or as a spread for sandwiches.

The secret is patience: onions need time to slowly release their natural sugars.
