Ingredients

Scale

Caramelized Onions

  • 2 tbsp unsalted butter
  • 2 tbsp vegetable oil
  • 2 large yellow onions (1 3/4 lb total), thinly sliced
  • 1/2 tsp kosher salt

Dip Base

  • 1/2 cup (4 oz) cream cheese, room temperature
  • 1/2 cup (4 oz) sour cream
  • 1/3 cup mayonnaise
  • Freshly ground black pepper, to taste
  • 2 tbsp sliced chives, for garnish
  • Potato chips, such as Ruffles, for serving

Instructions

  1. Caramelize the Onions: In a large skillet over medium heat, melt the butter and swirl in the vegetable oil. Add the thinly sliced onions along with 1/2 teaspoon kosher salt. Cook, stirring occasionally, until the onions start to soften and break down, about 10 to 12 minutes. Reduce the heat to medium-low and continue cooking, stirring every few minutes, until the onions turn golden brown and develop a deep caramelized flavor, about 40 minutes more. Transfer the caramelized onions to a medium bowl and let cool completely.
  2. Prepare the Dip Mixture: Once cooled, stir the caramelized onions into the cream cheese, sour cream, and mayonnaise until well combined. Season with additional salt and freshly ground black pepper to taste.
  3. Garnish and Serve: Top the dip with sliced chives for a fresh burst of color and mild onion flavor. Serve the caramelized onion dip alongside your favorite potato chips, such as Ruffles, for a deliciously satisfying snack or appetizer.

Notes

  • Be patient while caramelizing the onions; low and slow cooking develops the best flavor.
  • Allow the onions to cool completely before mixing with the cream cheese to avoid curdling.
  • This dip can be made a day ahead and refrigerated to let flavors meld; bring to room temperature before serving.
  • For a lighter version, substitute mayonnaise with Greek yogurt.
  • Try serving with fresh vegetables or crackers instead of potato chips for a healthier option.
