  • Total Time: 25 minutes
  • Yield: 4 servings

Ingredients

Scale
  • 1 pound lean beef sirloin or flank steak, thinly sliced
  • 3 medium zucchinis, sliced into half-moons
  • 2 tablespoons vegetable or sesame oil
  • 3 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated
  • 3 tablespoons soy sauce (low sodium preferred)
  • 1 tablespoon oyster sauce (optional)
  • 1 teaspoon cornstarch (optional, for thickening)
  • 1 teaspoon sesame oil (for flavor)
  • Red pepper flakes or sliced chili (optional, for heat)
  • Salt and black pepper to taste

Instructions

  1. Start by slicing the beef thinly across the grain and preparing the zucchini. Mince the garlic and grate the ginger for the flavorful base of your quick beef stir-fry.
  2. In a small bowl, combine 1 tablespoon of soy sauce, a pinch of salt, and pepper. Add the sliced beef and let it marinate for up to 10 minutes. This step enhances flavor and tenderizes the meat.
  3. Heat 1 tablespoon of vegetable or sesame oil in a large skillet or wok over medium-high heat. Add the marinated beef and stir-fry for about 2-3 minutes until browned and cooked through. Remove the beef and set aside.
  4. In the same pan, add a little more oil if needed. Stir in the minced garlic and grated ginger, cooking for about 30 seconds until fragrant.
  5. Add the sliced zucchini and stir-fry for 3-5 minutes until tender but still crisp. Season with a pinch of salt, pepper, and chili flakes if desired.
  6. Return the cooked beef to the skillet with the zucchini. Mix soy sauce, oyster sauce (if using), and cornstarch with a tablespoon of water to create a sauce. Pour into the skillet and cook for another 2 minutes until the sauce thickens. Finish with a drizzle of sesame oil.

Notes

  • Slice the beef very thin for quick tenderization and even cooking.
  • Do not overcrowd the pan to prevent steaming—cook in batches if necessary.
  • You can add extra vegetables like bell peppers, carrots, or broccoli for variety.
  • Adjust chili flakes to control the heat level.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave.
