Preheat your oven to 400°F (200°C).
Toss the sliced zucchini with olive oil, garlic powder, onion powder, smoked paprika, salt, and pepper.
Spread the zucchini on a baking sheet in a single layer.
Roast for 20–25 minutes until golden around the edges and tender inside.
Sprinkle with parmesan and herbs just before serving, if using.
Serve warm, and watch them disappear faster than your cousin’s pumpkin pie.
