Step-by-Step Instructions

Step 1 – Prepare the Beef

  1. Slice beef thinly against the grain for tenderness.
  2. Toss with cornstarch until evenly coated. Shake off excess.

Step 2 – Make the Sauce

  1. In a small bowl, whisk soy sauce, brown sugar, water, hoisin, ginger, garlic, and red pepper flakes. Set aside.

Step 3 – Stir-Fry the Beef

  1. Heat vegetable oil in a large skillet or wok over medium-high heat.
  2. Add beef in a single layer; sear for 1–2 minutes per side until browned (cook in batches if needed). Remove and set aside.

Step 4 – Cook the Sauce

  1. Pour prepared sauce into the pan.

Tips for Success

  • Slice Thinly – Freeze beef for 20 minutes before slicing to make it easier.
  • Don’t Overcrowd – Cook beef in batches for even browning.

  • Vegetable Boost – Stir-fry bell peppers, broccoli, or snap peas with the sauce.
  • Chicken or Tofu Version – Swap beef for cubed chicken breast or firm tofu.
