Begin by preheating the oven to 375 degrees.
Then take the edamame and place them in a strainer and run it under hot water to defrost. Spread them out on the paper towels to dry. Once dry, toss the edamame with oil, salt, and chili powder in a medium bowl.
Then take the edamame and spread it out on a rimmed baking sheet and roast for about 20 to 25 minutes. Make sure you shake and shift the baking sheet a few times during that time frame because you do not want the edamame to burn. Remove the sheet and allow them to cool. Transfer them to a bowl and serve.
1 16-oz. bag frozen shelled edamame

1 teaspoon salt
1/2 teaspoon chili powder
