Description
At its core, Mongolian Beef Noodles is a fusion-inspired stir-fry that combines thin strips of seared beef with long, slippery noodles tossed in a signature dark sauce. The dish strikes a perfect balance between sweet brown sugar, savory soy sauce, and aromatic garlic and ginger. Unlike standard noodle dishes that rely on heavy gravies, this recipe uses a light cornstarch coating on the meat to lock in moisture while allowing the savory sauce to cling to every single strand of noodle.
Ingredients
Scale
For the noodles
- 250–300 g (9–10 oz) noodles — lo mein, chow mein, egg noodles, or spaghetti
- 300 g (10–11 oz) beef steak, thinly sliced
- 1 tbsp cornstarch
- 2 tbsp cooking oil
- 3 cloves garlic, minced
- 1 tsp fresh ginger, grated
- 1 small onion, sliced
- 1 bell pepper, sliced
- 2–3 green onions, chopped
For the sauce
- ¼ cup soy sauce
- 2 tbsp brown sugar
- 1 tbsp oyster sauce
- 1 tbsp hoisin sauce
- 1 tbsp water
- 1 tsp sesame oil
- ½ tsp red chili flakes, optional
- ½ tsp black pepper
Instructions
- Prepare the beef: Pat the beef dry and slice it very thinly against the grain. Toss with cornstarch until lightly coated.
- Make the sauce: Mix soy sauce, brown sugar, oyster sauce, hoisin sauce, water, sesame oil, chili flakes, and black pepper in a bowl.
- Cook the noodles: Cook according to the package directions. Drain and set aside. Toss with a tiny amount of oil if necessary to prevent sticking.
- Sear the beef: Heat 1 tbsp oil in a large wok or skillet over high heat. Add the beef in a single layer and cook for about 2–3 minutes, turning once, until browned. Remove and set aside.
- Cook the vegetables: Add the remaining oil. Stir-fry the onion and bell pepper for 2 minutes. Add garlic and ginger and cook for another 30 seconds.
- Combine: Return the beef to the wok. Pour in the sauce and stir for 1–2 minutes, until the sauce becomes glossy and slightly thickened.
- Add noodles: Add the cooked noodles and toss everything together until the noodles are evenly coated with sauce.
- Finish: Stir in the green onions and serve immediately.
