For the Beef Marinade:
- 1/2 to 1 pound thin-sliced beef (flank steak, sirloin, or round steak)
- 1 tablespoon soy sauce
- 1 tablespoon Shaoxing wine, cooking sherry, or rice vinegar
- 1/4 teaspoon baking soda
- 1 teaspoon cornstarch
- 1 tablespoon oyster sauce
- 1 tablespoon soy sauce
- 1/4 cup beef stock
- 1 teaspoon cornstarch
- 1 teaspoon brown sugar
- 1 teaspoon sesame oil or chili sesame oil
- 1 green bell pepper, cut into strips
- 1 red bell pepper, cut into strips
- 1 small onion, thinly sliced
- 2-3 hot peppers of your choice (optional)
- 1-2 teaspoons minced garlic
- Optional: chili pepper flakes for extra heat
- 2-3 tablespoons sesame oil
Instructions
- Marinate the beef: In a gallon-sized zip-top bag, combine the sliced beef with 1 tablespoon soy sauce, 1 tablespoon Shaoxing wine, ¼ teaspoon baking soda, and 1 teaspoon cornstarch. Mix well to coat all the beef. Refrigerate for at least 30 minutes, or up to 2 hours for maximum tenderness.
- Prepare the cooking sauce: In a small bowl, whisk together the oyster sauce, soy sauce, beef stock, cornstarch, brown sugar, and sesame oil. Set aside.
- Prep the vegetables: Cut the bell peppers into strips or chunks about 1 inch in size. Slice the onion thinly. If using hot peppers, slice them. Mince the garlic.
- Cook the beef: Heat 1-2 tablespoons of oil in a large wok or skillet over medium-high to high heat. When the oil shimmers, add the marinated beef in a single layer (work in batches if needed to avoid crowding). Stir-fry for 3-4 minutes until the beef is browned but still slightly pink in the center.
- Transfer beef to a plate and set aside.
- Stir-fry the aromatics and vegetables: Add another tablespoon of oil to the same pan. Reduce heat to medium-high and add the minced garlic. Sauté for 30 seconds until fragrant. Add all the peppers and onions. Stir-fry for 3-4 minutes until the vegetables are tender-crisp and slightly charred but not mushy.
- Combine and sauce: Return the beef to the pan with the vegetables. Give the cooking sauce a quick stir and pour it over everything. Toss to coat and cook for 2-3 minutes, stirring constantly, until the sauce thickens and becomes glossy. For extra heat, add chili pepper flakes during this step.
- Serve: Remove from heat and serve immediately over Perfect Sticky Rice or fried rice.
