Preheat your oven to 425°F (220°C).
In a large bowl, combine shredded chicken, mozzarella, Parmesan, egg, garlic powder, Italian seasoning, salt, and pepper.
Mix until a dough-like consistency forms.
Line a baking sheet with parchment paper.
Spread the chicken mixture onto the parchment paper, shaping it into a pizza crust.
Bake the crust for 15 minutes until golden brown.
Remove the crust from the oven and add your favorite toppings.
Bake again for an additional 10 minutes until the cheese is bubbly.
Let cool for a few minutes before slicing.
Serve hot and enjoy your delicious chicken crust pizza!
