Step 1

Make the dressing: In a large bowl, whisk the mayonnaise, sour cream, lemon juice, mustard, salt, sugar, and pepper.

Step 2

To the dressing, add the chicken, scallions, celery, dill, and parsley. Toss until evenly combined. Taste and adjust seasoning, if necessary. Cover and refrigerate until ready to serve.

Step 3

Note: Poached chicken, leftover grilled chicken, or roasted/rotisserie chicken all work well for this recipe. If you'd like to roast bone-in chicken, you'll need 3 pounds bone-in, skin-on chicken breasts. Preheat the oven to 425°F and line a baking sheet with aluminum foil. Arrange the chicken breasts skin-side up on the prepared baking sheet. Coat with 1 tablespoon of olive oil and sprinkle both sides with 1 teaspoon salt and ½ teaspoon pepper. Roast for 30 to 35 minutes, or until done. Let cool before shredding.
