Ingredients
 

Chicken Salad

  • 4 cups shredded rotisserie chicken from one whole bird; shred very finely
  • 2 stalks celery, finely chopped
  • 0.25 cup yellow onion, very finely minced
  • 0.5 cup mayonnaise use more to taste if needed
  • 0.25 cup sour cream or swap some with Greek yogurt
  • 0.25 cup fresh lemon juice
  • 1 teaspoon white vinegar 1–2 tsp to taste; optional but deli-like
  • 0.5 teaspoon garlic powder
  • 0.25 teaspoon paprika
  • 0.25 teaspoon kosher salt plus more to taste
  • 0.25 teaspoon freshly ground black pepper
  • 1 tablespoon chopped fresh parsley or 1/4 tsp dried
  • 0.25 teaspoon granulated sugar optional; rounds acidity like deli version

Instructions
 

  • Shred chicken very finely. Stand mixer with paddle 20–30 seconds gives fluffy strands; or pulse in food processor carefully; or use two forks until pieces are rice-sized.
  • Finely dice celery and onion so the crunch is subtle and texture stays smooth.
  • Whisk mayonnaise, sour cream, and lemon juice until smooth. Stir in vinegar if using.
  • Season the dressing with garlic powder, paprika, salt, pepper, and parsley. Aim for balanced, mild flavor.
  • Combine chicken, celery, and onion in a bowl. Fold in dressing until every shred is lightly coated; add a spoon of mayo if too dry.
  • Cover and refrigerate 30 minutes before serving to let flavors meld.

Notes

Shred very finely for Costco texture. Chill 30+ minutes. For deli tang, add 1–2 tsp vinegar and 1/4 tsp sugar. Store chilled up to 4 days; don’t freeze dressed salad.
