4 servings

Ingredients

For the Beef

  • 1 lb (450 g) flank steak thinly sliced against the grain
  • 1/4 cup (30 g) cornstarch

For the Sauce

  • 1/2 cup (120 ml) low-sodium soy sauce or regular soy sauce
  • 1/2 cup (120 ml) water
  • 1/2 cup (100 g) brown sugar light or dark
  • 1/2 tsp red pepper flakes optional, more or less to taste

For Cooking & Garnish

  • 3 tbsp (45 ml) vegetable oil divided
  • 4 cloves garlic minced
  • 1 tbsp (15 g) fresh ginger minced
  • 4 green onions chopped, both white and green parts
  • sesame seeds for garnish; optional
  • steamed rice or noodles for serving

Equipment

  • Large skillet or wok
  • Mixing bowls
  • Knife
  • Tongs or spatula

Instructions
 

  1. Slice the flank steak thinly against the grain into ¼-inch slices. If needed, freeze the steak for 20 minutes first to make slicing easier.
  2. Place the steak slices in a bowl and toss with cornstarch until evenly coated. Set aside.
  3. In a small bowl, whisk together the soy sauce, water, brown sugar, and red pepper flakes (if using). Set aside.
  4. Heat 2 tablespoons of vegetable oil in a large skillet or wok over high heat. Working in batches, sear the steak slices in a single layer until browned and just cooked through, about 1–2 minutes per side. Don’t overcrowd the pan. Transfer cooked beef to a plate and repeat with remaining beef.
  5. Reduce heat to medium-high and add the remaining tablespoon of oil to the pan. Add the minced garlic and ginger. Sauté for 30 seconds, stirring constantly, until fragrant and golden.
  6. Pour in the sauce mixture. Allow it to come to a simmer and cook for 2–3 minutes, or until slightly thickened and glossy.
  7. Return the beef to the pan along with the chopped green onions. Toss everything together for 1–2 minutes until well-coated and heated through.
  8. Serve hot over steamed rice or noodles. Garnish with sesame seeds, if desired.

Notes

For make-ahead: Cook and cool, then refrigerate for up to 4 days, or freeze up to 2 months. Reheat gently on the stove or in the microwave with a splash of water as needed.
For less sweetness, reduce brown sugar to 1/3 cup. Add more veggies like bell pepper or snap peas if desired. For gluten-free, substitute tamari for soy sauce.
