A quick and easy recipe for crispy beef strips coated in a sticky, sweet-savory Mongolian sauce, garnished with fresh green onions for a perfect pop of flavor and crunch.

Ingredients

Scale
  • 1 pound flank steak or sirloin, thinly sliced against the grain
  • ½ cup cornstarch (about 60g)
  • ½ cup vegetable oil (about 120ml) for frying
  • ½ cup low sodium soy sauce (about 120ml)
  • ⅓ cup packed brown sugar (about 70g)
  • 3 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated
  • ¼ cup water (about 60ml)
  • ¼ teaspoon red pepper flakes (optional)
  • 45 stalks green onions, thinly sliced on the diagonal
  • 1 tablespoon toasted sesame seeds (optional)

Instructions

  1. Trim any excess fat from the beef, then slice the flank steak thinly against the grain into strips about ¼ inch thick.
  2. Place the cornstarch in a shallow bowl. Toss the beef strips in the cornstarch until lightly coated, shaking off excess.
  3. Heat vegetable oil in a large skillet or wok to about ¼ inch depth over medium-high heat until shimmering but not smoking (about 350°F).
  4. Fry the beef strips in batches, avoiding overcrowding, until golden and crispy, about 2-3 minutes per side. Remove and drain on paper towels.
  5. In a small bowl, whisk together soy sauce, brown sugar, minced garlic, grated ginger, water, and red pepper flakes if using.
  6. Pour the sauce mixture into the skillet used for frying (remove excess oil, leaving about 1 tablespoon). Cook over medium heat, stirring frequently, until thick and glossy, about 3-4 minutes.
  7. Return the fried beef to the skillet and toss thoroughly to coat with the sauce. Cook for another 1-2 minutes.
  8. Remove from heat and garnish generously with sliced green onions and toasted sesame seeds if using. Serve immediately.

Notes

If the sauce is too thick, add a splash of water to loosen it before tossing the beef. Do not overcrowd the pan when frying to keep beef crispy. Dry beef strips well before dredging to prevent sogginess. For gluten-free, substitute soy sauce with tamari or coconut aminos.
