Crispy fried beef strips are glazed in a citrusy sauce with dried orange peel and a whisper of chili heat. A protein-rich family favorite, this dish brings a zesty twist to Chinese takeout classics.
Slice beef flank steak thinly across the grain and pat the strips thoroughly dry with paper towels for a crispier fry.
Toss the beef strips in the cornstarch, ensuring each piece is evenly coated and excess starch is tapped off.
Heat the vegetable oil in a large skillet or wok over medium-high heat until shimmering but not smoking. In batches, fry the beef strips for 2-3 minutes per side until deep golden and crispy. Drain on a rack.
Wipe out excess oil from the pan, leaving about 1 tablespoon. Over medium heat, sauté minced garlic, grated ginger, dried orange peel, and chili flakes for about 30 seconds, stirring constantly to avoid burning.
Add soy sauce, sugar, rice vinegar, and orange juice to the pan. Simmer for 2-3 minutes, then return the beef to the sauce, tossing swiftly over high heat until all pieces are evenly glazed. Sprinkle with sliced green onions before serving.
