Slice beef thinly against the grain. This keeps it tender.
Optional: Marinate beef for 10–15 minutes with 1 tsp soy sauce and a pinch of sugar for extra flavor.
Heat the pan:
Heat 2 tbsp of oil in a large skillet or wok over medium-high heat.
Cook aromatics:
Add minced garlic and sliced chilies. Stir-fry for 30 seconds until fragrant.
Cook the beef:
Add beef slices and stir-fry quickly, about 2–3 minutes, until they start to brown.
Add onions and sauces:
Toss in the sliced onions and continue stir-frying until slightly softened.
Add soy sauce, oyster sauce, fish sauce (if using), sugar, and chili paste/Sriracha. Stir well to coat evenly.
Finish & serve:
Taste and adjust seasoning with pepper or extra chili if desired.
Garnish with sliced spring onions or fresh cilantro.
Serve immediately with steamed rice or noodles.
💡 Tip: For an even faster meal, you can pre-slice all veggies and beef, then stir-fry in high heat for just 5–6 minutes total. The beef will stay tender, and the onions will have a slight crunch.
If you want, I can also give you a sweet-spicy version with bell peppers and a sticky sauce that’s even more addictive. Do you want me to?
