If using frozen edamame, boil a pot of water and cook the edamame pods for 3-5 minutes until bright green and tender. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Once hot, add the minced garlic and sauté for about 1-2 minutes until fragrant but not browned.
Stir in the red pepper flakes, cooking for an additional 30 seconds to release the flavor.
Add the cooked edamame to the skillet, tossing to coat with the garlic and oil mixture.
Drizzle the soy sauce and sesame oil over the edamame, stirring to combine well. Cook for another 2-3 minutes, allowing the flavors to meld.
Taste and adjust seasoning with salt if needed.
Remove from heat and transfer the edamame to a serving bowl.
Sprinkle sesame seeds and chopped green onions on top for garnish before serving.
Notes
Adjust the red pepper flakes to your spice preference.
