A quick and easy stir-fry featuring crispy beef and tender broccoli in a savory sauce, perfect for busy weeknights.

Ingredients

Scale
  • 1 pound flank steak or sirloin, thinly sliced against the grain
  • Cornstarch (for coating and sauce thickening)
  • 2 tablespoons vegetable oil or peanut oil
  • Soy sauce (regular or low sodium), divided
  • 1 teaspoon sesame oil
  • 1 tablespoon fresh ginger, minced
  • 2 cloves garlic, minced
  • 4 cups broccoli florets (about 10.5 ounces)
  • Water (for steaming or blanching broccoli)
  • 1/4 cup soy sauce (60 ml)
  • 2 tablespoons oyster sauce (optional)
  • 1 tablespoon brown sugar
  • 1/2 cup beef broth or water (120 ml)
  • Cornstarch slurry made with 1 teaspoon cornstarch and 1 tablespoon water

Instructions

  1. Place the flank steak in the freezer for about 20 minutes to firm up, then slice thinly into strips about 1/4 inch thick.
  2. In a bowl, combine 2 tablespoons soy sauce, 1 teaspoon sesame oil, minced garlic, and ginger. Toss the beef slices in the marinade and let sit for 15 minutes.
  3. Cut broccoli into bite-sized florets. Blanch in boiling water for 1-2 minutes until bright green and just tender. Drain and set aside. Alternatively, steam broccoli for 3-4 minutes.
  4. Drain excess marinade from beef, then toss beef slices in cornstarch until lightly but evenly coated. Shake off excess cornstarch.
  5. Heat 2 tablespoons vegetable oil in a wok or skillet over medium-high heat until shimmering. Add half the beef in a single layer and cook about 2 minutes per side until golden and crispy. Remove to a plate and repeat with remaining beef.
  6. In a small bowl, whisk together 1/4 cup soy sauce, oyster sauce, brown sugar, beef broth, and cornstarch slurry. Set aside.
  7. Reduce heat to medium. Add broccoli to the wok and stir-fry briefly for 1 minute. Pour sauce over broccoli and stir until it thickens, about 1-2 minutes.
  8. Add crispy beef back in and toss everything together to coat evenly.
  9. Drizzle a few drops of sesame oil for aroma, toss once more, and remove from heat. Serve immediately.

Notes

Do not overcrowd the pan when frying beef to keep it crispy. For extra crunch, dip beef slices in beaten egg before coating with cornstarch. Use high heat to seal in juices and achieve a golden crust. Add sauce last and stir quickly to avoid overcooking broccoli. Reheat leftovers in a skillet to maintain crispiness.
