Onion beef is a savory, flavorful dish where thinly sliced beef is cooked with lots of onions and often a rich, slightly sweet and savory sauce. It’s common in Asian-inspired stir-fries and home-style meals.
🥩 What it is
- Tender beef slices
- Sweet and soft onions
- Sauce made with soy, garlic, and sometimes sugar or oyster sauce
- Served over rice or noodles
🧾 Ingredients
- 1 lb (450 g) beef (sirloin, flank, or ribeye), thinly sliced
- 2–3 medium onions, sliced
- 2–3 garlic cloves, minced
- 2–3 tbsp soy sauce
- 1–2 tsp sugar or honey
- 1 tbsp oyster sauce (optional)
- 1–2 tbsp oil for stir-frying
- Optional: bell peppers, green onions, sesame seeds
👨🍳 Method
1. Prep the beef
- Slice beef thinly against the grain for tenderness
- Marinate briefly in soy sauce, garlic, and a pinch of sugar (10–15 min)
2. Cook the onions
- Heat oil in a skillet or wok
- Stir-fry onions (and bell peppers if using) until soft and slightly caramelized
3. Cook the beef
- Add beef to the pan, stir-fry quickly over high heat until just browned
- Don’t overcook—thin slices cook fast
4. Combine and season
- Add oyster sauce (if using) and a little extra soy sauce or sugar
- Stir for 1–2 minutes until beef and onions are coated and glossy
5. Serve
- Over steamed rice or noodles
- Garnish with chopped green onions or sesame seeds
💡 Tips
- Slice onions thinly so they cook evenly with the beef
- High heat is key for a good stir-fry texture
- You can add a splash of water or beef broth if the sauce needs loosening
