Preheat your oven to 350ºF. This is the perfect temperature to ensure your biscuits bake evenly and come out golden brown.
Spray a regular muffin pan with nonstick cooking spray. This prevents the biscuits from sticking and makes cleanup a breeze.
In a large bowl, stir together the cooked chicken, mayonnaise, chopped celery, Worcestershire sauce, and half of the cheddar cheese. Mix well to combine all the flavors.
Season the mixture with salt and pepper to taste. Adjust the seasoning based on your preference for a perfect flavor.
Open a can of refrigerated biscuits. Carefully separate the biscuit dough into 10 individual biscuits.
Using a rolling pin, roll each biscuit into a large circle. Aim for about 5 to 6 inches in diameter to ensure they fit well in the muffin pan.
Firmly press the dough into the bottom and up the side of each muffin cup. This creates a nice shell for your chicken salad filling.
Spoon the chicken mixture into each biscuit cup, filling them generously. Don’t be shy; the more, the merrier!
Bake in the preheated oven for 17 to 20 minutes. Keep an eye on them, and look for a golden brown color on the biscuits.
Once baked, sprinkle the remaining cheddar cheese on top and let them cool for a few minutes. Sprinkle with dried parsley if desired for an extra touch of flavor.
