Preheat oven to 375°F. Drain the edamame, and make sure they are completely dry.
Combine all the ingredients in a bowl and toss until it is all combined and the edamame are all coated. Spray a large baking sheet with oil. Put edamame on baking sheet, making sure they are in a single layer on the baking sheet.
Roast in a preheated oven for 35-45 minutes. Make sure to stir them halfway through the baking time. If they start to get too dark, you can turn the oven down to 325°F.
Take them out of the oven when they are browned and pretty crispy (I kind of burned some of mine, but they were still good). Allow edamame to cool completely on the baking sheet. They will get crispier as they cool. Enjoy!
