Blanch the Green Beans: Begin by bringing a large pot of water to a rolling boil. Add a generous pinch of salt to the boiling water, then carefully add the trimmed green beans. Blanch the beans for approximately 3 minutes, or until they turn a vibrant green and are just tender. Once done, drain the beans and immediately plunge them into a bowl filled with ice water. This will halt the cooking process and help retain their color. After the beans have chilled, drain them again and set aside.
Prepare the Sauce: In a small mixing bowl, combine the minced garlic, sesame oil, soy sauce, and red pepper flakes (if you're using them for a touch of heat). Stir the mixture thoroughly to ensure the flavors meld, then set the bowl aside for later.
Sauté the Green Beans: Heat the olive oil in a large skillet over medium-high heat. Once the oil is shimmering, add the blanched green beans to the skillet. Sauté for about 3-4 minutes, stirring occasionally, until the beans develop a slight caramelization and are crisp-tender.
Add the Sauce: Pour your prepared garlic and sesame sauce over the sautéed green beans in the skillet. Stir everything together well, cooking for an additional 2 minutes to help the flavors combine beautifully.
Finish with Sesame Seeds: Sprinkle the toasted sesame seeds over the green beans and gently toss to ensure they are evenly coated. Taste the dish and season with salt as desired, adjusting to your preference.
Garnish and Serve: Carefully transfer the sesame garlic green beans to a serving dish. For an added touch of freshness and color, garnish with the thinly sliced green onions before serving.
