Ingredients

Scale
  • 12 oz flank steak (or sirloin/skirt), thinly sliced against the grain

  • 1 tsp cornstarch

  • 2 tsp neutral oil (vegetable, canola, or avocado)

  • 1 tsp water

  • ¼ tsp baking soda (optional)

  • 4 cups mixed vegetables (bok choy, broccoli florets, mushrooms, sugar snap peas)

  • 1 Tbsp fresh ginger, minced

  • 1 Tbsp garlic, minced

  • ½ cup water or beef/chicken stock

  • 2 tsp light soy sauce

  • 1 tsp dark soy sauce

  • 1 Tbsp oyster sauce

  • ¼ tsp sesame oil

  • ¼ tsp sugar

  • 1 tsp cornstarch mixed with 1 Tbsp water (slurry)

  • Additional oil for stir-frying

Instructions

  • In a bowl, combine sliced beef with cornstarch, oil, water, and baking soda. Mix well and let marinate for at least 30 minutes.

  • Prepare all vegetables by washing and cutting into uniform sizes. Set aside.

  • In a small bowl, mix soy sauces, oyster sauce, sesame oil, sugar, and stock. Set aside.

  • Heat 2 tablespoons oil in a wok or large skillet over high heat.

  • Sear beef in a single layer for about 30 seconds per side. Remove and set aside.

  • Add 1 tablespoon oil to the pan. Stir-fry ginger for 10 seconds, then garlic for another 5 seconds.

  • Add firmer vegetables like mushrooms and broccoli. Stir-fry for about 30 seconds.

  • Add quick-cooking vegetables like bok choy and snap peas. Stir-fry for another 30 seconds.

  • Pour in the sauce and return beef to the pan. Toss everything to combine.

  • Add cornstarch slurry and stir until sauce thickens and evenly coats all ingredients.

  • Remove from heat and serve immediately over rice or noodles.

Notes

  • For extra tenderness, slice beef while it’s slightly frozen.

  • Swap beef for tofu, chicken, or shrimp for variations.

  • Customize vegetables based on season or what you have on hand.

  • Avoid overcooking the vegetables to maintain their crunch.

  • Add chili flakes or sriracha for a spicy version.
