Ingredients

Beef

  • 1 lb flank steak, very thinly sliced against the grain
  • 1 tsp cornstarch (for a quick marinade)
  • 1 tsp light vegetable oil (to help the marinade)

Vegetables & Aromatics

  • 4 cups broccoli florets (about 1 large head)
  • 3 cloves garlic, finely minced
  • 1 tbsp fresh ginger, minced
  • 2 stalks green onions, sliced (for garnish)

Sauce & Thickener

  • 1/3 cup low-sodium soy sauce
  • 1 tsp rice vinegar
  • 1 tsp honey
  • 1 tbsp cornstarch (to make a slurry)
  • 2 tbsp water (for the slurry)

Oils & Finishes

  • 1 1/2 tbsp neutral oil (vegetable or peanut), divided
  • 1 tsp toasted sesame oil (added at the end)
  • 1 tsp toasted sesame seeds (optional)
  • freshly ground black pepper, to taste

Instructions

Preparation Steps

  • Trim any excess fat from the steak and slice it very thin across the grain. In a medium bowl toss the beef with 1 tsp cornstarch, 1 tsp oil and a few cracks of black pepper. Let rest 8–10 minutes while you prep the veg.
  • Bring a medium pot of water to a boil. Add the broccoli florets and blanch for 60–90 seconds until bright green and just tender. Immediately drain and plunge into iced water to stop cooking; drain again and set aside.
  • Whisk the sauce: combine the soy sauce, rice vinegar and honey in a small bowl. In a separate small cup mix 1 tbsp cornstarch with 2 tbsp water until smooth and set both mixtures aside.
  • Heat a large wok or heavy skillet over high heat until very hot. Add 1 tbsp neutral oil and swirl. Working in a single layer cook half the beef for 45–60 seconds per side until just browned but not fully cooked through. Remove to a plate and repeat with the remaining beef, adding the remaining 1/2 tbsp oil if needed.
  • Lower the heat to medium-high and return the pan to the stove. Add the minced garlic and ginger and stir for 20–30 seconds until aromatic (don’t let it burn).
  • Add the blanched broccoli and the cooked beef back to the pan. Pour the soy-honey mixture over everything and stir to combine.
  • Give the cornstarch slurry a quick stir and drizzle it into the hot pan while stirring constantly. Cook for 1–2 minutes until the sauce thickens and coats the beef and broccoli.
  • Remove the pan from heat and stir in the toasted sesame oil. Taste and adjust with a pinch of pepper or a splash more soy if needed. Sprinkle sliced green onions and sesame seeds on top before serving.
  • Serve immediately over steamed rice or cauliflower rice for a lower-carb option.

Notes

Tip: For the best texture, don’t overcrowd the pan when searing the beef—work in batches. Leftovers keep well in the fridge for 3 days and reheat quickly in a skillet.
