Lean Beef & Onion Stir-Fry

Ingredients

• lean beef sirloin — 300 g, sliced thin against the grain
• onion — 1 medium, sliced
• soy sauce — 2 tbsp
• cornstarch — 1 tbsp
• cooking oil — 2 tbsp
• black pepper — 1/4 tsp
• sugar — 1/2 tsp

Steps (beginner-friendly)

1. Slice the beef thin against the grain (perpendicular to the muscle lines) so it stays tender.
2. Toss the beef with 1 tbsp soy sauce, cornstarch, and black pepper; marinate 10 minutes.
3. Heat 1.5 tbsp oil in a wok over high heat until smoking slightly.
4. Add the beef in one layer and sear 1 minute, then stir-fry 1-2 more minutes until no pink remains; remove to a plate.
5. Add the remaining oil and the onion; stir-fry 2-3 minutes until soft and lightly golden at the edges.
6. Return the beef, add 1 tbsp soy sauce and the sugar, and toss 1 minute until glossy.
7. Serve hot with rice.
