Step‑by‑Step Instructions for Mongolian Beef Noodles
Step 1: Marinate Beef
In a mixing bowl, combine the sliced beef with salt, soy sauce, cornstarch, and baking soda. Use your hands to ensure each strip is well-coated. Let the beef marinate for 20-30 minutes at room temperature. This process enhances tenderness and flavor, setting the stage for your delicious Mongolian Beef Noodles.
Step 2: Prepare Noodles
While the beef is marinating, cook the udon noodles according to the package instructions. Aim for 1-2 minutes less than the suggested time for an al dente texture. Once done, drain the noodles and toss them lightly with a splash of vegetable oil to prevent sticking, allowing you to easily incorporate them later.
Step 3: Stir Fry Beef
Heat a wok or large skillet over high heat and add vegetable oil, ensuring it shimmers but doesn’t smoke. Add the marinated beef in a single layer, cooking for about 3-4 minutes undisturbed until nicely browned. Stir-fry until cooked through, about another 2 minutes. Transfer the beef to a plate, keeping that flavorful crispy texture intact.
Step 4: Sauté Aromatics
In the same wok, add a bit more oil if needed and quickly stir-fry minced garlic, ginger, and sliced white onion for 30 seconds until fragrant. Toss in the Thai red chilies, green bell pepper, and carrot matchsticks; continue stir-frying for another 2-3 minutes, letting the veggies soften while retaining some crunch for added texture.
Step 5: Combine Ingredients
Pour in a mixture of oyster sauce, dark soy sauce, brown sugar, and chicken stock, bringing the sauce to a gentle simmer. Add the cooked udon noodles and the stir-fried beef back into the wok. Toss everything together for about 2-3 minutes, ensuring the noodles and beef are evenly coated in the glossy sauce while heated through.
Step 6: Serve
Once everything is well combined and heated, remove from heat and prepare to serve. Garnish your Mongolian Beef Noodles with fresh green onion slices and a sprinkle of sesame seeds if desired. Serve hot and enjoy the heartwarming blend of flavors you’ve created in just 25 minutes!

Mongolian Beef Noodles Recipe FAQs
How to choose the beef for Mongolian Beef Noodles?
Absolutely! I recommend using flank or sirloin beef for the best flavor and tenderness. Look for cuts that have a nice marbling of fat, which enhances juiciness when cooked. Fresh beef should have a bright red color with no dark spots, indicating it’s at its prime.
How long can I store leftovers of Mongolian Beef Noodles?
You can store leftover Mongolian Beef Noodles in an airtight container in the fridge for up to 5 days. Ensure the dish cools to room temperature before sealing. To reheat, simply warm it in a pan or microwave with a splash of water to keep the noodles from drying out.
Can I freeze Mongolian Beef Noodles?
Very! To freeze, cool the noodles completely and store them in a freezer-safe container, separating the beef and vegetables if possible. This helps maintain texture. They can be frozen for up to 3 months. When ready to eat, thaw overnight in the fridge and reheat in a pan over medium heat with a splash of water until warmed through.
What if my beef doesn’t turn crispy?
If your beef isn’t crispy, it might be due to overcrowding the pan or not heating the oil enough before adding the beef. Make sure to cook it in batches and let the oil shimmer over high heat for optimal frying conditions. Also, pat the beef dry before marinating to eliminate excess moisture!
Are Mongolian Beef Noodles suitable for gluten-free diets?
Definitely! To make this dish gluten-free, you can substitute regular soy sauce with tamari and use rice noodles instead of udon noodles. Just ensure that all other ingredients, like oyster sauce, are also labeled gluten-free.
