Make tender beef and crisp broccoli in a savory homemade sauce with this straightforward weeknight recipe.

Ingredients

Scale
  • 1 pound flank steak or sirloin, thinly sliced against the grain
  • 1 tablespoon soy sauce (for marinating)
  • 1 teaspoon cornstarch (for marinating)
  • 1 teaspoon vegetable oil (for marinating)
  • 1 pound fresh broccoli florets
  • 2 tablespoons vegetable oil, divided
  • 3 cloves garlic, minced
  • 1 tablespoon fresh ginger, minced
  • 1/2 cup beef broth
  • 1/4 cup soy sauce
  • 2 tablespoons oyster sauce
  • 1 tablespoon brown sugar
  • 1 teaspoon sesame oil
  • 1 teaspoon cornstarch (for sauce thickening)
  • 2 tablespoons cold water (for cornstarch slurry)

Instructions

  1. Prepare the beef: In a bowl, combine the sliced beef with 1 tablespoon soy sauce, 1 teaspoon cornstarch, and 1 teaspoon vegetable oil. Mix well and let it sit for 10 minutes. This is the velveting step for tender beef.
  2. Blanch the broccoli: Bring a small pot of water to a boil. Add the broccoli florets and cook for 1 to 2 minutes until bright green. Immediately drain and plunge the broccoli into ice water to stop the cooking process. Drain well.
  3. Mix the sauce: In a small bowl, whisk together the beef broth, 1/4 cup soy sauce, oyster sauce, brown sugar, and sesame oil. Set aside.
  4. Cook the beef: Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the marinated beef in a single layer (cook in batches if necessary) and stir fry for 2 to 3 minutes until browned. Remove the beef from the skillet and set aside.
  5. Sauté aromatics: Add the remaining 1 tablespoon of vegetable oil to the skillet. Add the minced garlic and ginger and cook for about 30 seconds until fragrant.
  6. Combine: Return the cooked beef to the skillet. Add the blanched broccoli. Pour the prepared sauce mixture over the beef and broccoli.
  7. Thicken the sauce: In a small cup, mix 1 teaspoon of cornstarch with 2 tablespoons of cold water to create a slurry. Pour the slurry into the skillet while stirring constantly. Cook for 1 minute until the sauce thickens and coats the beef and broccoli.
  8. Serve immediately over steamed white or brown rice.

Notes

  • For the best texture, slice the beef when it is partially frozen; this makes thin slicing easier.
  • Do not overcook the broccoli; blanching quickly keeps it crisp and green.
  • Use flank steak or sirloin for this recipe; both work well for quick stir-frying.
