Step-by-Step Instructions
Step 1: Cook the Noodles
Boil water in a medium pot and cook noodles according to package directions. Drain and rinse under cold water to stop cooking. Set aside.
Step 2: Marinate the Beef
In a bowl, toss sliced beef with cornstarch, soy sauce, sesame oil, and garlic powder. Let sit for 10–15 minutes while you prepare the sauce and veggies.
Step 3: Make the Mongolian Sauce
In a small bowl, whisk together soy sauce, brown sugar, hoisin, oyster sauce, vinegar, sesame oil, garlic, ginger, red pepper flakes, and broth. Set aside the cornstarch slurry (1 tbsp cornstarch + 1 tbsp water) to thicken later.
Step 4: Cook the Beef
Heat 1 tbsp oil in a large skillet or wok over medium-high heat. Add the marinated beef in a single layer (work in batches if needed) and cook for 2–3 minutes per side until browned. Transfer to a plate and set aside.
Step 5: Sauté the Veggies
In the same skillet, add another tbsp of oil. Toss in green onions, carrots, and bell pepper. Stir-fry for 2–3 minutes until just tender.
Step 6: Combine Everything
Return the cooked beef to the skillet. Pour in the sauce and bring to a simmer. Add the cornstarch slurry and stir until the sauce thickens and becomes glossy—about 2 minutes.
Step 7: Toss with Noodles
Add the cooked noodles to the skillet and toss everything together until well coated. Let cook for 1–2 more minutes so the flavors absorb.
Step 8: Serve and Garnish
Remove from heat and sprinkle with sesame seeds and extra green onions. Serve hot and enjoy your homemade takeout-style meal.
Tips for Perfect Mongolian Beef Noodles
Slice Beef Thin – Freezing the beef for 15–20 minutes before slicing helps get thin, even slices.
Don’t Overcook – Stir-fry beef just until browned to keep it tender.
Prep Everything First – Stir-fries move fast, so have all ingredients chopped and ready.
Balance the Sauce – Taste before serving and adjust with extra soy sauce or sugar to your preference.
Use the Right Noodles – Lo mein, udon, or even rice noodles work beautifully here.
Serving Suggestions
Serve with steamed broccoli or bok choy on the side.
Pair with a fresh cucumber salad for a cooling contrast.
Add a soft-boiled or fried egg on top for extra richness.
Chili oil or sriracha can be drizzled for more heat.
A side of pickled veggies helps cut through the savory flavors.
