Method
- Prepare the Beef: In a bowl, combine the sliced beef with soy sauce, cornstarch, sesame oil, baking soda (if using), and egg white (if using). Mix well and let it marinate for at least 30 minutes, or up to a few hours in the refrigerator.
- Make the Sauce: In a separate bowl, whisk together soy sauce, oyster sauce, brown sugar, cornstarch, sesame oil, white pepper, and beef broth until smooth. Set aside.
- Stir-Fry the Vegetables: Heat 1 tablespoon of vegetable oil in a large wok or skillet over high heat. Add the sliced onion and bell peppers and stir-fry for 3-5 minutes, until slightly softened but still crisp. Remove the vegetables from the wok and set aside.
- Cook the Beef: Heat the remaining 1 tablespoon of vegetable oil in the wok over high heat. Add the marinated beef and stir-fry for 2-3 minutes, until browned and cooked through. Be careful not to overcrowd the wok; cook in batches if necessary.
- Combine and Simmer: Return the cooked vegetables to the wok with the beef. Pour the sauce over the mixture and bring to a simmer, stirring constantly until the sauce has thickened and coats the beef and vegetables.
- Serve: Serve immediately over steamed rice. Garnish with sesame seeds and chopped green onions, if desired.
Notes
For best results, use a hot wok or cast iron skillet. Slice the beef thinly against the grain to ensure tenderness. Marinating the beef for a longer period will enhance its flavor and tenderness. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave. You can add other vegetables, such as mushrooms or broccoli, to the stir-fry. Adjust the amount of red pepper flakes to your preferred level of spiciness.
