Step 1: Poach the Chicken: Gently poach the chicken breasts in simmering water or chicken broth until cooked through. This typically takes about 20-25 minutes. Ensure the internal temperature reaches 165F (74C). Allow the chicken to cool slightly before shredding it into bite-sized pieces. This step is crucial for maintaining the chicken's moisture and tenderness.
Step 2: Prepare the Dressing: In a large bowl, whisk together the mayonnaise, lemon juice, and Dijon mustard until smooth and well combined. This creates the creamy and tangy base for the chicken salad. Adjust the amount of lemon juice to taste, depending on desired tanginess.
Step 3: Combine Ingredients: Add the shredded chicken, diced celery, red onion, parsley, and toasted nuts to the bowl with the dressing. Gently fold all ingredients together until they are evenly coated with the dressing. Be careful not to overmix, as this can make the chicken salad mushy.
Step 4: Season to Taste: Season the chicken salad with salt and freshly ground black pepper to taste. Start with a small amount and adjust as needed. Consider adding a pinch of red pepper flakes for a subtle kick.
Step 5: Chill and Serve: Cover the bowl and refrigerate the chicken salad for at least 30 minutes to allow the flavors to meld together. This also helps to firm up the salad, making it easier to serve. Serve chilled on croissants, lettuce wraps, or with crackers. Garnish with fresh parsley or a sprinkle of toasted nuts, if desired.
Optional Tip: For a sweeter variation, consider adding 1/4 cup of dried cranberries or grapes. For a spicier kick, a dash of hot sauce or a pinch of cayenne pepper can be added to the dressing. To substitute the toasted nuts, you can use sunflower seeds or pumpkin seeds for a nut-free option. For a dairy-free version, substitute the mayonnaise with a dairy-free alternative.
