- Save some cooking water to adjust the dressing’s consistency for a creamier texture.

- Prepare the Dressing: In a bowl, combine sour cream, mayonnaise, white wine vinegar, chopped parsley, chopped chives, and soy sauce. Mix well. Adjust the thickness of the dressing by adding some cooled pasta water if needed.
- Combine Pasta and Dressing: Toss the cooled pasta with the dressing until evenly coated.
- Assemble and Serve: Transfer the dressed pasta to a serving bowl. Top with reserved caramelized onions, additional parsley leaves, and fresh cracked black pepper. Serve at room temperature or chilled. Store leftovers in the refrigerator for up to two days.
