If using frozen edamame, cook according to package instructions until tender, then drain and set aside. Fresh edamame should be boiled in salted water for about 5-6 minutes until tender.
In a large skillet, heat the olive oil over medium heat. Once hot, add the minced garlic and sauté for 1-2 minutes until fragrant, being careful not to burn it.
Stir in the chili paste and soy sauce, mixing well to create a spicy garlic sauce.
Add the cooked edamame to the skillet and toss to coat thoroughly in the sauce. Continue to stir-fry for about 3-4 minutes, allowing the flavors to meld.
Drizzle with sesame oil, sprinkle with sea salt, and toss once more to combine.
Remove from heat and transfer the spicy garlic edamame to a serving bowl.
Garnish with sesame seeds and chopped green onions, if desired.
Notes
Adjust the chili paste according to your spice preference.
