- Combine Ingredients:
Return the cooked beef to the skillet with the vegetables. In a small bowl, whisk together the soy sauce, oyster sauce, sesame oil, and beef broth. Pour the sauce over the stir-fry, tossing to coat evenly. Stir in the cornstarch slurry and cook for 1–2 minutes until the sauce thickens and coats the meat and vegetables. - Add Noodles and Toss:
Add the cooked noodles to the skillet and gently toss everything together until the noodles are fully coated in the sauce and combined with the beef and vegetables. Cook for an additional 1–2 minutes to heat through. - Serve and Garnish:
Serve hot, garnished with chopped green onions and sesame seeds if desired. This dish is excellent on its own or paired with an extra drizzle of sesame oil or chili flakes for heat.
Tip: This recipe is easily adaptable. Swap in other veggies like cabbage, mushrooms, or zucchini depending on what you have on hand. For added heat, include fresh chili or sriracha in the sauce mix.
