Ingredients
Method
Make the chicken salad
- Combine the shredded cooked chicken, mayonnaise, celery, and red onion in a bowl and stir until evenly coated. Aim for a creamy consistency with no dry chicken pockets.
- Stir in the dijon mustard and halved grapes until the fruit is distributed throughout the salad. Mix gently so the grapes stay intact.
- Season the chicken salad with salt and pepper to taste, then stir to fully incorporate. Taste once more and adjust before chilling.
- Chill the chicken salad for at least 30 minutes to let the flavors meld, covered in the refrigerator. Keep it cold until ready to fill the croissants.
Assemble and serve
- Split the croissants and fill generously with the chilled chicken salad. Keep the filling packed for a hearty, tidy bite.
- Serve immediately or wrap individually for a make-ahead brunch spread. If packing ahead, keep sandwiches chilled and serve the same day for best texture.
Notes
Pro tip: Use day-old croissants if possible, as slightly firmer pastry holds up better to the creamy filling. Refrigerate the chicken salad (covered) for up to 3 days; assemble sandwiches within 24 hours for the best flakiness. Freeze the chicken salad for up to 2 months, thaw overnight in the refrigerator, and stir well before filling croissants. For a lighter option, replace half the mayonnaise with plain Greek yogurt to keep the texture creamy while reducing richness.
