Method
- Marinate the Beef: In a medium bowl, combine the sliced beef with soy sauce, rice wine (or sherry), cornstarch, sesame oil, ginger, and black pepper. Mix well and marinate for at least 30 minutes, or up to 2 hours in the refrigerator.
- Prepare the Vegetables: While the beef is marinating, prepare the bell peppers and onion. Mince the garlic.
- Make the Sauce: In a small bowl, whisk together the beef broth, soy sauce, oyster sauce, brown sugar, cornstarch, sesame oil, and black pepper until the cornstarch is fully dissolved. Set aside.
- Stir-Fry the Vegetables: Heat the vegetable oil in a large wok or skillet over high heat. Add the bell peppers and onion and stir-fry for 2-3 minutes, or until they are crisp-tender. Add the minced garlic and stir-fry for another 30 seconds until fragrant. Remove the vegetables from the wok and set aside.
- Cook the Beef: Add a little more oil to the wok if needed. Add the marinated beef to the wok in a single layer (work in batches if necessary to avoid overcrowding). Stir-fry for 2-3 minutes, or until the beef is browned and cooked through. Remove the beef from the wok and set aside.
- Combine and Simmer: Pour the sauce into the wok and bring to a simmer, stirring constantly until the sauce thickens (about 1-2 minutes). Add the cooked beef and vegetables back into the wok and toss to coat everything evenly with the sauce.
- Serve: Serve immediately over rice or noodles. Garnish with sesame seeds and chopped green onions, if desired.
Notes
For best results, slice the beef thinly against the grain. Marinating the beef for longer will result in more tender meat. If you don't have oyster sauce, you can substitute with hoisin sauce. Store leftovers in an airtight container in the refrigerator for up to 3 days.
