Serves

2–3 people
Prep: 20 minutes
Cook: 10–12 minutes

Ingredients

Beef

450 g (1 lb) beef sirloin, flank steak, or ribeye
Slice thinly against the grain

Vegetables

1 red bell pepper, sliced
1 green bell pepper, sliced
1 yellow bell pepper, sliced
1 medium onion, sliced
2 cloves garlic, minced
1 tsp fresh ginger, grated (optional but 🔥)

Marinade (for tender beef)

1 tbsp soy sauce
1 tbsp oyster sauce
1 tsp cornstarch
1 tsp oil (vegetable or sesame)
½ tsp black pepper

Stir-Fry Sauce

2 tbsp soy sauce
1 tbsp oyster sauce
1 tbsp hoisin sauce (optional, adds depth)
½ cup beef broth or water
1 tsp sugar (or honey)
1 tsp cornstarch
½ tsp black pepper

For Cooking

2 tbsp vegetable oil
Optional garnish: chopped parsley or scallions

Instructions

1. Marinate the Beef

Add sliced beef to a bowl with all marinade ingredients.
Mix well and let it rest for 15–20 minutes.

This step keeps the beef juicy and tender—don’t skip it.

2. Mix the Sauce

In a small bowl, whisk together all stir-fry sauce ingredients until smooth.
Set aside.

3. Sear the Beef

Heat 1 tbsp oil in a wok or large skillet over high heat
Add beef in a single layer (cook in batches if needed)
Sear 30–45 seconds per side until just browned
Remove beef and set aside

The beef should be browned, not fully cooked yet.

4. Cook the Vegetables

Add remaining 1 tbsp oil
Toss in onions, cook 1 minute
Add bell peppers, garlic, and ginger
Stir-fry 2–3 minutes until slightly tender but still crisp

5. Bring It All Together

Return beef to the pan
Pour in the sauce
Toss everything together
Cook 1–2 minutes until sauce thickens and coats everything beautifully

Final Touch

Taste and adjust:

More soy sauce for salt
More black pepper for heat
Splash of water if sauce is too thick

Garnish with parsley or scallions.
