Equipment

  • Large skillet or wok with lid
  • Cutting board
  • Sharp knife
  • Small bowl
  • Whisk
  • Tongs or spatula

Ingredients

Beef

  • 1 pound flank steak sliced thin against the grain
  • 1 tablespoon low-sodium soy sauce
  • 1 tablespoon cornstarch

Sauce

  • ¼ cup low-sodium soy sauce
  • ⅓ cup low-sodium beef broth or water
  • 2 tablespoons light brown sugar
  • 1 tablespoon oyster sauce
  • 2 teaspoons cornstarch
  • 1 teaspoon toasted sesame oil

Stir fry

  • 2 tablespoons vegetable oil divided
  • 4 cups broccoli florets about 1 large head
  • 2 tablespoons water
  • 3 cloves garlic minced
  • 1 tablespoon fresh ginger minced
  • Cooked white rice for serving (optional)

Instructions

  • Toss the sliced beef with 1 tablespoon soy sauce and 1 tablespoon cornstarch. Set aside while you make the sauce.
  • Whisk together the 1/4 cup soy sauce, broth, brown sugar, oyster sauce, 2 teaspoons cornstarch, and sesame oil.
  • Heat 1 tablespoon of the vegetable oil in a large skillet or wok over high heat. Add the broccoli and stir fry for 1 minute, then add the 2 tablespoons water, cover, and steam for 2 minutes, until bright green and tender-crisp. Transfer to a plate.
  • Add the remaining 1 tablespoon oil to the pan. Add the beef in a single layer, in two batches if needed, and sear for 1–2 minutes per side, until browned. The beef should reach at least 145°F (63°C).
  • Reduce the heat to medium. Push the beef to one side, add the garlic and ginger, and cook for 30 seconds, until fragrant.
  • Stir the sauce, pour it into the pan, and simmer for 1–2 minutes, stirring, until thickened and glossy.
  • Return the broccoli and toss everything to coat. Serve right away, over rice if desired.

Notes

Freeze the steak for 20–30 minutes before slicing to make thin, even slices easier.
Sirloin or skirt steak can replace flank steak. Always slice against the grain.
