Preheat the oven to 400 ˚F. Line a baking sheet with parchment paper.
Pour the edamame on the baking sheet and spread it with your fingers so that it is in one layer.
Drizzle with olive oil. Sprinkle with Parmesan, salt and pepper. Mix with your hands and make sure it is coated evenly.
Bake in the preheated oven for 15 minutes.
