Costco Chicken Salad (Copycat Recipe)


Make a homemade version of the famous Costco Chicken Salad, but without any of the preservatives or questionable ingredients. This easy shredded chicken salad is great served on top of lettuce or toast. This recipe is gluten-free with dairy-free options.


Units Scale
  • 1 3pound cooked rotisserie-style chicken, cooled and pulled apart into medium-sized pieces, bones and skin removed
  • 1/2 cup mayonnaise
  • 1/2 cup sour cream (for dairy-free diets, use a dairy-free version)
  • 2 tablespoons white wine vinegar
  • 1/2 lemon, juiced (about 1 tablespoon)
  • 1/2 teaspoon sea salt
  • 2 teaspoons sugar (leave out for sugar-free diets)
  • 6 celery ribs, finely diced
  • 1/2 white onion, finely diced


  1. Place the cooked and cooled chicken in a food processor fitted with the “S” blade. Turn it on for about 15-20 seconds to shred the chicken. Or, you can also just use a sharp knife to finely chop the chicken for the salad. The Costco version is finely shredded.
  2. Place the finely shredded or chopped chicken in a large mixing bowl. Set aside.
  3. Then, in a medium bowl, combine the mayonnaise, sour cream, vinegar, lemon juice, onion, salt, and sugar. Stir to combine until smooth.
  4. Pour the mayonnaise mixture over the chicken. Add the celery and onion and stir to combine.
  5. Serve immediately, or cover and chill until you’re ready to serve.


  1. Most cooked rotisserie chickens you find in grocery stores weigh about 2 pounds. The Costco rotisserie chickens weigh about 3 pounds.
  2. To reduce the amount of fat in this recipe, you can replace the sour cream with unsweetened Greek style yogurt, if you prefer.
  3. This recipe can easily be doubled or even tripled if you need more servings.
  4. Store any leftovers in a tightly covered container in the refrigerator for up to 4 days.
