Ingredients

Scale
  • 1 pound (450 g) flank steak or sirloin, thinly sliced against the grain
  • 4 cups (about 300 g) fresh broccoli florets, washed and trimmed
  • 3 cloves garlic, minced
  • 1 teaspoon fresh ginger, grated (optional)
  • 3 tablespoons soy sauce (low sodium if preferred)
  • 1 tablespoon oyster sauce
  • 1 teaspoon toasted sesame oil
  • 1 teaspoon brown sugar
  • 1 tablespoon rice vinegar or mirin
  • 1/2 teaspoon freshly ground black pepper
  • 1 teaspoon cornstarch mixed with 2 tablespoons cold water
  • 2 tablespoons vegetable or canola oil

Instructions

  1. Slice 1 pound (450 g) of flank steak thinly against the grain into strips about 1/4-inch (0.6 cm) wide and set aside in a bowl.
  2. In the bowl with beef, add 1 tablespoon soy sauce, 1 teaspoon cornstarch, and 1 teaspoon vegetable oil. Toss to coat and let rest for 10 minutes.
  3. Wash and cut broccoli into bite-size florets (about 4 cups or 300 g). Peel and slice stalks into thin coins if using.
  4. In a small bowl, whisk together 2 tablespoons soy sauce, 1 tablespoon oyster sauce, 1 teaspoon sesame oil, 1 teaspoon brown sugar, 1 tablespoon rice vinegar, and 1 teaspoon grated ginger (optional). Set aside.
  5. Heat wok or large skillet over medium-high heat. Add 2 tablespoons vegetable oil and swirl to coat. Add minced garlic and stir for about 15 seconds until fragrant.
  6. Add marinated beef strips in a single layer (in batches if needed). Stir-fry for 2-3 minutes until browned but not fully cooked. Remove beef to a plate.
  7. Add a splash more oil if needed. Toss in broccoli and stir-fry for 3-4 minutes until bright green and crisp-tender.
  8. Return beef to pan with broccoli. Pour prepared stir-fry sauce over everything. Stir well and cook for 1-2 minutes until sauce thickens and coats beef and broccoli evenly. If sauce is thin, gradually add cornstarch slurry, stirring constantly.
  9. Taste and adjust seasoning with more soy sauce or black pepper if needed. Remove from heat and optionally sprinkle with toasted sesame seeds or sliced green onions.
  10. Serve hot over steamed rice or noodles.

Notes

Slice beef thinly against the grain for tenderness. Use medium-high heat and avoid overcrowding the pan to keep broccoli crisp. Marinate beef for at least 10 minutes for best flavor and texture. For gluten-free, substitute soy sauce with tamari and use gluten-free oyster sauce or omit it. Leftovers keep well refrigerated for up to 3 days; reheat gently with a splash of water or broth.
