In a small bowl, whisk together the oil, salt, pepper, onion powder, and garlic powder. drizzle over edamame and then toss to combine. Bake for 22-25 minutes (stir halfway through) or until the beans are whistling and are lightly browned and crispy. Remove from oven, sprinkle with Parmesan cheese, and toss to combine.
