Step 1: Poach the Chicken: Place the chicken breasts in a large saucepan and cover with 4 cups of water. Add teaspoon salt and teaspoon black pepper. Bring to a simmer over medium heat, then reduce the heat to low, cover, and poach for 20-25 minutes, or until the chicken is cooked through. An internal temperature of 165F (74C) should be reached.
Step 2: Cool and Shred the Chicken: Remove the chicken from the saucepan and let it cool slightly. Once cool enough to handle, shred the chicken using two forks or your fingers. Place the shredded chicken in a large mixing bowl.
Step 3: Toast the Pecans (Optional): While the chicken is poaching, preheat a small skillet over medium heat. Add the chopped pecans and toast for 3-5 minutes, stirring frequently, until fragrant and lightly browned. Be careful not to burn them. Remove from the skillet and let cool.
Step 4: Prepare the Remaining Ingredients: While the chicken is cooling, halve the grapes and finely dice the celery.
Step 5: Make the Dressing: In a small bowl, whisk together the mayonnaise, sour cream, honey, lemon juice, and celery salt.
Step 6: Combine Ingredients: Add the halved grapes, diced celery, and toasted pecans to the bowl with the shredded chicken. Pour the dressing over the mixture and stir gently to combine.
Step 7: Chill and Serve: Cover the bowl and refrigerate the chicken salad for at least 30 minutes to allow the flavors to meld. Before serving, taste and adjust seasoning with salt and pepper as needed. Garnish with fresh parsley, if desired. Serve chilled on croissants, lettuce cups, or crackers.
Optional Tip: For a sweeter salad, add a tablespoon of brown sugar to the dressing. If you dont have pecans, walnuts or almonds can be substituted. For a lighter version, use Greek yogurt in place of sour cream or light mayonnaise.
