Preparation Steps
In a medium bowl, combine soy sauce, sesame oil, and cornstarch. Add sliced flank steak and toss to coat. Let marinate for 10 minutes.
Heat vegetable oil in a large skillet or wok over medium-high heat. Add beef and stir-fry until browned and cooked through, about 4-5 minutes. Remove beef and set aside.
In the same skillet, add garlic and ginger; sauté for 30 seconds until fragrant.
Add hoisin sauce, rice vinegar, brown sugar, and red pepper flakes if using. Stir to combine and let sauce simmer for 1-2 minutes.
Return beef to skillet and toss to coat with sauce. Cook for another minute until heated through.
Serve immediately garnished with toasted sesame seeds and sliced green onions over steamed rice.
Notes
You can substitute flank steak with sirloin or skirt steak. Serve with steamed broccoli or snap peas for a complete meal.
