Ingredients
Scale
1½ lbs beef sirloin, thinly sliced
2 tbsp cornstarch
1 tbsp soy sauce
½ tsp black pepper
1 tbsp vegetable oil
¼ cup soy sauce (for stir-fry sauce)
2 tbsp oyster sauce
1 tbsp brown sugar
½ cup beef broth
1 tsp sesame oil
1 tsp cornstarch (for stir-fry sauce)
½ tsp freshly ground black pepper (for stir-fry sauce)
1 red bell pepper, sliced
1 green bell pepper, sliced
1 medium onion, sliced
3 cloves garlic, minced
1 tsp fresh ginger, minced
2 tbsp vegetable oil (for vegetables)
2 green onions, sliced
Instructions
Prepare the Beef: In a bowl, toss the sliced beef with cornstarch, soy sauce, and black pepper until evenly coated. Set aside for 10 minutes.
Make the Sauce: In a small bowl, whisk together soy sauce, oyster sauce, brown sugar, beef broth, sesame oil, cornstarch, and black pepper. Set aside.
Cook the Beef: Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the beef in batches and stir-fry for 2–3 minutes until browned. Remove and set aside.
Cook the Vegetables: Add the remaining vegetable oil to the same skillet. Sauté garlic and ginger for about 30 seconds until fragrant.
Add the sliced onion and bell peppers. Stir-fry for 3–4 minutes until slightly tender but still crisp.
Combine Everything: Return the cooked beef to the skillet. Pour in the prepared sauce and toss everything together.
Cook for another 2–3 minutes, stirring constantly, until the sauce thickens and coats the beef and vegetables.
Stir in the sliced green onions and remove from heat.
Serve hot over steamed rice or noodles.
Notes
For a spicier version, add sliced jalapeños or red pepper flakes.
Feel free to substitute the beef with chicken or tofu for a different protein option.
Serve with steamed rice or noodles for a complete meal.
