How to Make Leftover Chicken Breast Salad
Step 1: Prep the leftover chicken
Check the leftover chicken breast and remove any bones, skin, or tough pieces if needed. Using a sharp chef’s knife, cut or shred the cooked chicken into small, bite-size pieces.
If the chicken is already shredded, simply break up any large clumps with your fingers or a fork. Set it aside while you prepare the fresh ingredients.
Step 2: Chop the vegetables, grapes, lemon, and dill
Use a cutting board and sharp knife to finely chop the celery and red onion. Halve the grapes if they are large, then finely chop the fresh dill.
Squeeze the juice from half of the lemon. Keep the chopped ingredients close by so everything can go into the bowl at once.
Step 3: Make the creamy dressing
In a large mixing bowl, add the mayonnaise, Dijon mustard, lemon juice, and celery seeds if using.
Stir until the mixture is smooth. Season with kosher salt and black pepper to taste.
Step 4: Mix the chicken salad
Add the leftover chicken breast, celery, red onion, grapes, and dill to the bowl.
Fold everything together with a spatula or large spoon until the chicken is evenly coated and the vegetables and grapes are spread throughout. Taste and adjust the salt and pepper if needed.
Serve immediately, or cover the bowl and refrigerate the chicken salad until ready to eat.

Conclusion
Leftover chicken breast gets a much fresher second act here: creamy dressing, crisp celery, juicy grapes, sharp onion, and plenty of dill turn yesterday’s chicken into a cool, satisfying salad. It is the kind of leftover solution that requires more chopping than cooking—which, in this case, is exactly the point.
