Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the shredded chicken, celery, mayonnaise, cheddar cheese, salt, and black pepper. Mix well.
Transfer the mixture to a greased 9x13-inch baking dish.
Top with sliced almonds and crushed potato chips for a crunchy finish.
Bake in the preheated oven for 25-30 minutes, or until bubbly and golden on top.
Serve warm and enjoy!
