Ingredients

Scale
  • 3 large yellow onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon kosher salt, plus more to taste
  • 1/2 teaspoon freshly ground black pepper
  • 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
  • 1 tablespoon dry sherry or white wine (optional)
  • 16 ounces full-fat sour cream
  • 8 ounces cream cheese, softened to room temperature
  • 2 teaspoons Worcestershire sauce
  • 1 teaspoon garlic powder

Instructions

  1. Caramelize the onions. In a large skillet or Dutch oven, melt butter with olive oil over medium-low heat. Add sliced onions and 1 tsp salt. Cook for 45-60 minutes, stirring every 5-7 minutes, until deeply golden brown. In the last 10 minutes, add pepper, thyme, and sherry (if using). Stir until liquid evaporates. Let cool completely.
  2. Combine the base. In a large bowl, beat softened cream cheese and sour cream with a hand mixer or whisk until completely smooth. Stir in Worcestershire sauce and garlic powder.
  3. Fold and season. Add the cooled caramelized onions to the creamy base, reserving about 2 tablespoons for garnish. Fold together gently but thoroughly. Taste and adjust seasoning with more salt or pepper if needed.
  4. Chill and serve. Transfer dip to a serving bowl, cover, and refrigerate for at least 1 hour to allow flavors to meld. Garnish with reserved onions and an extra sprinkle of thyme before serving.

Notes

For best results, do not rush the caramelization. Let onions cool completely before adding to the dairy to prevent a runny dip. The dip can be made 1-2 days ahead; flavor improves with time. Serve with potato chips, fresh vegetables, or pretzels.
