Preheat the oven to 400°F. Line a baking sheet with parchment paper or very generously grease a 13-inch pizza pan with cooking spray.
In a medium bowl, combine the ground chicken, eggs, garlic powder, onion powder and oregano with 1/2 teaspoon kosher salt and 1/4 teaspoon black pepper. Using a spatula or your hands, mix together the ingredients until well-combined.
Transfer the mixture onto the parchment paper and spread it into an even layer that’s roughly 1/4-inch-thick.
Bake the pizza base until it golden brown, about 25 minutes. Remove it from the oven and let it cool for 10 minutes.
Spread the pizza sauce, then top it with the shredded mozzarella cheese and your preferred pizza toppings.
Increase the oven temperature to 450°F.
Return the pizza to the oven until the cheese is melted, about 5 minutes. (For even more golden-brown color, place the pizza under the broiler for about 1 minute, but keep an eye on it, as the cheese will turn golden very quickly.)
Remove the pizza from the oven and let it cool for 10 minutes before slicing and serving.
