How to Make Mongolian Beef Noodles
1. Marinate the Beef
Add the thinly sliced beef to a bowl with oyster sauce, soy sauce, cornflour, baking soda, and white pepper. Toss until the beef is evenly coated.
Let it marinate for about 15 minutes while you prepare the remaining ingredients.
In a separate bowl, whisk together all the sauce ingredients until well combined.
2. Prepare the Noodles
Prepare the frozen udon noodles according to the packet directions.
Once cooked, drain the noodles and set them aside.
3. Cook the Beef
Heat a large wok or frying pan over high heat and add the avocado oil.
Cook the beef in batches so the pieces have enough space to brown properly. Cook for approximately 1–2 minutes per side, until browned.
Remove the cooked beef from the pan and set aside.
4. Stir-Fry the Aromatics
Add the sliced onion to the same pan and cook for about 2 minutes.
Add the minced garlic, ginger paste, and dried chilli peppers. Stir-fry for approximately 30 seconds, until fragrant.
5. Add the Vegetables
Add the red capsicum, green capsicum, and sliced mushrooms.
Stir-fry for around 3 minutes, or until the vegetables begin to soften while retaining some texture.
6. Combine the Beef, Noodles and Sauce
Add the prepared noodles to the pan.
Pour over the homemade sauce and return the cooked beef to the wok.
Stir everything together and simmer for approximately 2 minutes, allowing the sauce to become glossy and lightly thickened.
Stir through the spring onions just before serving.
7. Garnish and Serve
Divide the Mongolian beef noodles between four servings.
Finish with sesame seeds, extra spring onion, and chilli flakes if desired.
Serve immediately while hot.
Tips for Making Mongolian Beef Noodles
Slice the beef thinly: Thin slices cook quickly and help create tender beef in a hot wok.
Don't overcrowd the pan: Cooking the beef in batches helps it brown instead of steaming.
Use high heat: A hot wok or large frying pan helps create that classic stir-fry texture.
Prep everything first: Stir-frying moves quickly, so have your beef, vegetables, noodles, and sauce ready before you start cooking.
Adjust the spice: Use fewer dried chillies for a milder dish or add extra chilli flakes for more heat.
Choose your noodles: Udon gives the dish a chewy texture, while egg noodles or rice noodles can also work well.
Easy Meal Prep Dinner
These high-protein Mongolian beef noodles can also work well for meal prep. Divide the finished noodles into four meal-prep containers and refrigerate appropriately.
For the best texture, store garnishes such as sesame seeds, extra spring onion, and chilli flakes separately and add them when serving.
