The BEST Chicken Sandwich Filling

chicken sandwich filling
Perfectly poached chicken in a creamy dressing spiked with red onions, gherkins and parsley. This Chicken Sandwich Filling is the answer to your next picnic, afternoon tea or grazing platter. Whether it's in finger sandwiches, stuffed into a brioche roll or wrapped up in a flat bread, this is absolutely delicious and so easy to make.
  • 900g chicken breast poached and finely chopped – this is approximately 4 small or 3 large chicken breasts (see note 1)
  • 1 cup whole egg mayonnaise
  • 1/3 cup finely diced celery
  • 1/3 cup finely diced red onion
  • 1/3 cup finely chopped pickles or gherkins
  • 1/4 bunch parsley finely chopped
  • S&P to taste (I used 1 tsp of salt and 1/2 tsp pepper)
  • 16 slices of bread to make 8 sandwiches or 6 brioche rolls (pictured)
  1. Combine all ingredients in a medium sized bowl. Serve on sandwiches or brioche rolls.

Note 1: I use this foolproof, easy, poached chicken recipe. You can view the recipe here. You can also use roast chicken leftovers.

Can Chicken Sandwich Filling be made ahead? Yes. Keep it refrigerated in an air tight container for up to 3 days.

Can you freeze Chicken Sandwich Filling? I do not recommend freezing chicken sandwich filling. Mayonnaise does not tend to freeze well, it can separate and the chicken can also dry out. This one is best made fresh and kept in the fridge.
