Ingredients

Scale

For the Dip

  • 3 tablespoons extra-virgin olive oil
  • 2 large yellow onions, julienned
  • 1½ teaspoons kosher salt, plus more to taste
  • Freshly ground black pepper, to taste
  • 2 cups sour cream
  • 2 tablespoons mayonnaise

To Garnish and Serve

  • Chopped fresh chives, to garnish
  • Potato chips, to serve

Instructions

  1. Caramelize the Onions: In a large skillet, heat the extra-virgin olive oil over medium heat. Add the julienned onions and season with 1½ teaspoons kosher salt. Cook, stirring frequently, for about 8 to 10 minutes until the onions begin to soften and shrink in size. Then reduce the heat to medium-low and continue cooking, stirring occasionally, for an additional 25 to 30 minutes until the onions are golden brown and deeply caramelized. To prevent burning, add a few tablespoons of water to deglaze the pan and scrape up any browned bits if needed. Remove the caramelized onions from heat and let them cool completely.
  2. Mix the Dip: In a large bowl, combine the cooled caramelized onions with sour cream and mayonnaise. Stir thoroughly until all ingredients are well blended into a smooth, creamy mixture.
  3. Garnish and Serve: Transfer the onion dip to a serving dish. Garnish with chopped fresh chives and freshly ground black pepper to taste. Serve immediately alongside potato chips for dipping and enjoy the rich, savory flavors.

Notes

  • For best flavor, caramelize onions slowly and patiently to develop deep sweetness.
  • If not serving immediately, cover and refrigerate the dip for up to 2 days.
  • Consider adding a splash of Worcestershire sauce or a pinch of smoked paprika for a slight twist.
  • Use thinly sliced onions for more even caramelization.
  • Adjust seasoning with salt and pepper to suit your taste.
