Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Thaw the frozen edamame and pat them extremely dry with a clean kitchen towel to ensure they get crispy rather than steamed.
In a large mixing bowl, whisk together the olive oil, garlic powder, onion powder, sea salt, and black pepper.
Add the dried edamame to the bowl and toss thoroughly until every bean is lightly coated in the oil and spice mixture.
Sprinkle the finely grated parmesan cheese over the edamame and toss once more so the cheese sticks to the beans.
Spread the edamame in a single layer on the baking sheet, making sure they are not touching to allow for even roasting.
Bake for 15 to 20 minutes, shaking the pan halfway through, until the cheese is golden and the edamame is noticeably crunchy.
Allow the edamame to cool on the pan for 5 minutes to further crisp up before serving warm.
