Method
Coat the beef
- Toss the sliced flank steak with cornstarch, salt, and black pepper until the beef is well coated and looks dry-sticky at the edges.
- Heat enough oil for 1/2 inch deep in a deep pot or Dutch oven until it reaches 350°F, indicated by active bubbling around a tiny beef piece.
Fry until extremely crispy
- Fry the beef in batches for 2–3 minutes per batch at 350°F, until the strips are extremely crispy and golden, then drain on paper towels.
Make and simmer the chilli sauce
- Mix the sweet chilli sauce, soy sauce, rice vinegar, brown sugar, and sesame oil together until smooth.
- Heat 1 tablespoon oil in a wok or skillet, then cook the minced garlic and sliced red chilli for 30 seconds, until fragrant and sizzling.
- Add the chilli sauce mixture and simmer for 1 minute, until it looks glistening and slightly thickened.
Toss and serve immediately
- Add the crispy beef and toss quickly to coat in the sauce so the surface turns glossy red-orange without soaking, indicated by crisp edges still showing.
- Serve immediately over cooked rice to preserve the crunch, then garnish with green onions and sesame seeds.
Notes
For maximum crunch, fry in small batches and toss the beef with sauce at the very end—once coated, serve right away. Store leftovers covered in the fridge up to 3 days, but note the beef will soften; reheat in a hot pan to re-crisp a bit. Freezing is not recommended for best texture. For a gluten-free swap, use gluten-free soy sauce in the chilli sauce.
