Blanch the beans: Bring a large pot of generously salted water to a boil. Add the green beans (1 pound) and cook for 2 minutes, just until bright green. Drain and plunge immediately into ice water to stop the cooking. Drain again and pat completely dry with paper towels — dry beans sear better and won’t steam in the pan.
Make the sauce. In a small bowl, whisk together soy sauce (2 tablespoons), oyster sauce (1 tablespoon), rice vinegar (1 tablespoon), brown sugar (2 teaspoons), water (2 teaspoons), Shaoxing wine (1 tablespoon), and cornstarch (1/2 teaspoon) until smooth. Set aside.
Stir-fry the aromatics. Heat the vegetable oil (2 tablespoons) in a large skillet or wok over medium-high heat. Add the ginger (1 teaspoon) first and cook for about 10–15 seconds. Add garlic (4 cloves) and crushed red pepper flakes (1/2 teaspoon) (if using). Stir-fry for another 20–30 seconds, just until fragrant and lightly golden. (Optional: set aside a few slices of garlic for garnish.)
Cook the beans. Add the blanched and well dried green beans to the pan. Stir-fry for 2–3 minutes, until slightly blistered and glossy.
Add the sauce. Whisk the sauce again, then pour it into the pan. Toss well to coat. Cook for another 2–3 minutes, allowing the sauce reduce until it clings to the beans beautifully.
Garnish
Finish and serve. Turn off the heat. Drizzle with sesame oil (1 teaspoon), toss again, and top with sesame seeds (1 teaspoon), scallions, and optional roasted cashews or peanuts. Serve hot and enjoy!
🌶 Pro Tip: Always dry your blanched green beans thoroughly before stir-frying. Excess water will steam them instead of letting them develop that gorgeous light char and glossy coating. That one step makes all the difference between good beans and restaurant-perfect beans.
Notes
Dry beans = better blister. Pat those beans dry like you mean it — water is the enemy of crisp edges.
Don’t overcook. You want them tender-crisp with a little snap. Overcooking dulls the color and the flavor.
Balance the glaze. Taste as it reduces — a splash of vinegar or a pinch of sugar can fine-tune the final flavor perfectly.
Double the sauce! If you’re serving these with rice or noodles, make extra glaze — it’s too good not to drizzle over everything.
