These are an addictive snack, excellent on their own (with a cold one!) or as a salad garnish. Depending on the oven, these can be ready in as few as 20 or as long as 40 minutes, so keep an eye out! The important thing is to give them a good shake/mix halfway through so that everything crisps up without burning. The end result should taste savory, salty, and delicious.
Open the bag of edamame. Rinse under warm water to remove any remnant ice, and drain. Spread onto a kitchen towel or paper towels and pat dry (they won't crisp up if still wet).
In a medium bowl, mix together the olive oil, garlic powder, salt, and pepper. Add the edamame and toss. Sprinkle on Parmesan and lemon zest and toss again to combine.
Spread the edamame on a parchment-lined baking sheet and bake for 15 to 20 minutes, then remove to give them a good mix so that everything cooks evenly. Cook for another 10 to 15 minutes, making sure they don't burn. Let them cool a bit before enjoying on their own or in a salad. Store in an airtight container.
