Ingredients

Scale
  • 8 oz (225 g) flank steak, thinly sliced against the grain
  • 2 teaspoons soy sauce
  • 1 teaspoon cornstarch
  • 1 teaspoon sesame oil
  • 3 cups broccoli florets (fresh or frozen)
  • 2 cloves garlic, minced
  • 1 teaspoon ginger, freshly grated (optional)
  • 2 tablespoons vegetable or canola oil
  • 3 tablespoons soy sauce
  • 1 tablespoon oyster sauce
  • 1 tablespoon brown sugar
  • 1/4 cup beef broth or water
  • 1 teaspoon cornstarch mixed with 2 teaspoons water (slurry)

Instructions

  1. Slice and marinate the beef: Thinly slice 8 oz flank steak against the grain. In a bowl, mix 2 teaspoons soy sauce, 1 teaspoon cornstarch, and 1 teaspoon sesame oil. Toss the beef slices in this marinade and set aside for at least 5 minutes.
  2. Prep the broccoli and aromatics: Cut broccoli into bite-sized florets (about 3 cups). Mince 2 garlic cloves and grate 1 teaspoon fresh ginger.
  3. Mix the sauce: In a small bowl, whisk together 3 tablespoons soy sauce, 1 tablespoon oyster sauce, 1 tablespoon brown sugar, and 1/4 cup beef broth or water. Prepare the cornstarch slurry by mixing 1 teaspoon cornstarch with 2 teaspoons water separately.
  4. Cook the beef: Heat 2 tablespoons vegetable oil in a large skillet or wok over medium-high heat until shimmering. Add the marinated beef in a single layer and sear for 1-2 minutes per side until browned but not fully cooked. Remove beef from pan and set aside.
  5. Stir fry the broccoli and aromatics: In the same pan, add more oil if needed. Toss in garlic and ginger, sauté for 30 seconds until fragrant. Add broccoli florets and stir fry for 3-4 minutes until bright green and crisp-tender. Add a splash of water if needed to steam.
  6. Combine and finish: Return the beef to the pan with broccoli. Pour in the prepared sauce and stir to coat. Add the cornstarch slurry and cook for 1-2 minutes, stirring constantly until sauce thickens and becomes glossy. Adjust seasoning if needed.
  7. Serve hot: Remove from heat and serve immediately over steamed rice or noodles.

Notes

Marinate beef briefly with cornstarch and sesame oil to keep it tender. Cook beef in batches to avoid steaming. Use fresh garlic and ginger for best flavor. Add a splash of water to steam broccoli if needed. For gluten-free, substitute tamari for soy sauce and ensure oyster sauce is gluten-free or use coconut aminos.
