This easy recipe creates a classic caramelized onion dip, perfect for entertaining. Thinly sliced onions are slowly caramelized with sage until deep golden, then cooled and folded into a creamy blend of mayonnaise and sour cream, seasoned to perfection. The dip is then chilled to allow flavors to meld, resulting in a rich and savory accompaniment to potato chips.
For optimal caramelization, ensure your onions are sliced uniformly thin; this promotes even cooking. The 'low and slow' method is crucial here – resist the urge to rush the process, as true caramelization develops deep, sweet flavors. Letting the onions cool completely before incorporating them into the dairy base is paramount to prevent separation and maintain a smooth, creamy texture. While sage is specified, a touch of thyme or even a pinch of dried oregano could offer a different aromatic profile. Consider adding a small splash of balsamic vinegar or Worcestershire sauce to the onions during the last few minutes of cooking for an extra layer of complexity and umami. The two-hour refrigeration period is non-negotiable for the flavors to fully meld and deepen, transforming it from good to truly exceptional.
