Preheat your oven to 400°F (204°C). Line a baking sheet with parchment paper. If using a pizza stone, place it in the oven while preheating to help the underside of the crust brown evenly.
In a large mixing bowl, combine the ground chicken, grated Parmesan cheese, garlic powder, dried oregano, salt, black pepper, and egg. Mix gently until all ingredients are evenly incorporated. Avoid overmixing, as this can make the crust tough. The mixture will naturally be moist and sticky.
Transfer the chicken mixture onto the prepared parchment-lined baking sheet. Using a spatula or wet hands, spread it into a round approximately 10–12 inches wide and 1/4 inch thick. Keep the thickness even and the edges slightly raised. If excess moisture collects on the surface, gently blot it with a paper towel.
Bake the chicken crust for 20–22 minutes at 400°F (204°C), until the top is firm, the edges are golden, and the chicken is fully cooked. Remove from the oven and allow the crust to rest for 3–5 minutes.
For a firmer, crispier crust, carefully flip the baked chicken base using another piece of parchment paper and return it to the oven for an additional 5 minutes. This step is optional.
Spread a thin layer of your favorite pizza sauce over the cooked chicken crust. Add cheese and your preferred pizza toppings, avoiding excessive sauce or heavy toppings that could soften the crust.
Return the topped pizza to the oven at 400°F (204°C) and bake for another 8–10 minutes, or until the cheese has melted and is bubbling.
Remove the finished pizza from the oven and let it cool for approximately 2 minutes before slicing. Cut into portions and serve warm.
