Preheat the oven to 375°F (190°C).
Scoop out the centers of each zucchini half to create boats, leaving a thin border; lightly salt the zucchini and arrange them on a baking sheet.
In a mixing bowl, combine shredded chicken, buffalo sauce, softened cream cheese, ranch dressing, garlic powder, onion powder, salt, and black pepper until creamy.
Spoon the buffalo chicken mixture evenly into each zucchini boat.
Sprinkle shredded cheese generously over the filled zucchini halves.
Bake in the preheated oven for 18 to 22 minutes, until zucchini is tender and cheese is melted with a light golden color.
Optionally drizzle with extra buffalo sauce and garnish with green onions or parsley before serving.
Serve hot as a light meal, snack, or side dish alongside salad or garlic bread.
