In a large mixing bowl, combine the shredded chicken, cottage cheese, mozzarella cheese, grated Parmesan, breadcrumbs, eggs, garlic powder, onion powder, Italian seasoning, salt, and pepper. Mix until the ingredients are well incorporated.
In a greased 9x13-inch baking dish, layer the zucchini rounds evenly on the bottom.
Pour the chicken mixture over the zucchini, spreading it out evenly.
Bake in the preheated oven for 25-30 minutes, or until the top is golden and bubbly.
Remove from the oven and let it cool for a few minutes before serving.
Garnish with fresh basil leaves before slicing and serving.
Notes
Use whole grain breadcrumbs for a healthier option.
