Follow these easy steps to prepare your crunchy roasted edamame snack:

1. Preheat the oven to 400°F (200°C).
2. Rinse the frozen edamame in cold water and drain well. This step ensures that any ice crystals are removed, allowing the edamame to roast evenly.
3. In a bowl, toss the edamame with olive oil, salt, garlic powder, and chili flakes. Make sure each pod is well-coated with the seasoning.
4. Spread the edamame on a baking sheet in a single layer. This will help them cook evenly and become crispy.
5. Roast for 20-25 minutes, stirring halfway through to ensure even cooking, until the edamame is crispy and golden brown.
6. Let cool slightly before serving. Enjoy your healthy and delicious snack!
