Ingredients

Scale

Dip Ingredients

  • 3 tablespoons extra-virgin olive oil
  • 2 large yellow onions, julienned
  • Kosher salt and freshly ground black pepper, to taste
  • 2 cups sour cream
  • 2 tablespoons mayonnaise
  • Chopped fresh chives, to garnish

Serving

  • Potato chips, to serve

Instructions

  1. Caramelize the Onions: In a large skillet, heat the olive oil over medium heat. Add the julienned onions and season with 1½ teaspoons of kosher salt. Cook, stirring frequently, until the onions begin to soften and reduce in size, approximately 8 to 10 minutes. Reduce the heat to medium-low and continue cooking, stirring occasionally, until the onions are deeply caramelized and golden brown, about 25 to 30 minutes. If the onions start to burn or get too dark, deglaze the pan by adding a few tablespoons of water and scraping up the browned bits. Set the caramelized onions aside to cool.
  2. Mix the Dip: In a large bowl, combine the cooled caramelized onions with sour cream and mayonnaise. Stir well until all ingredients are evenly incorporated.
  3. Garnish and Serve: Transfer the dip to a serving dish and garnish with chopped fresh chives and freshly ground black pepper. Serve immediately with potato chips for dipping.

Notes

  • Slow, patient caramelization of onions is key to developing rich flavor.
  • Deglazing the pan prevents burning and adds extra flavor.
  • This dip is best served fresh but can be refrigerated for up to 2 days.
  • For a thinner consistency, add a small splash of milk or buttermilk before serving.
  • Use high-quality sour cream and mayonnaise for the best taste.
  • Pairs excellently with potato chips, crackers, or fresh vegetable sticks.
