Save this recipe on:

When you need a comforting dinner with bold flavor and minimal fuss, Mongolian Beef Noodles will never steer you wrong. This dish brings together tender strips of beef, glossy soy-based sauce, and springy noodles with sweet red bell peppers and green onions for color and crunch. It tastes like takeout but feels like home.

It’s perfect for busy weeknights when you crave something warm, hearty, and full of umami. Plus, the entire dish cooks in one pan, which means easy prep and even easier cleanup. Whether you’re meal prepping for the week or serving a crowd, Mongolian Beef Noodles always hits the spot.

What Kind of Noodles Work Best?

For this dish, lo mein noodles or even spaghetti work beautifully. You want noodles that can hold sauce well without turning soggy. If you’re after more chew and authenticity, try using fresh Asian-style egg noodles from the refrigerated section. Even ramen noodles can do in a pinch!

Ingredients for the Mongolian Beef Noodles

• Beef sirloin or flank steak: Thinly sliced against the grain for tenderness and quick cooking.
• Lo mein noodles or spaghetti: The perfect base to soak up all the delicious sauce.
• Soy sauce: Delivers that rich, salty umami flavor essential to Mongolian-style dishes.
• Brown sugar: Adds the signature sweetness that balances the savory soy.
• Garlic and ginger: Bring warmth and aromatic complexity.
• Red bell pepper: For sweetness, crunch, and vibrant color.
• Green onions: Stirred in at the end for a bright, fresh finish.
• Cornstarch: Helps give the beef that lightly crisp texture and thickens the sauce.
• Sesame oil and vegetable oil: Layered oils for flavor and high-heat cooking.

How To Make the Mongolian Beef Noodles

Step 1: Prep the Beef

Slice the beef into thin strips and toss with cornstarch. Let it sit for 10 minutes while you prep the other ingredients. This helps the meat crisp up and absorb the sauce better.

Step 2: Cook the Noodles

Boil your noodles according to the package instructions. Drain and toss with a bit of sesame oil to keep them from sticking together.

Step 3: Sear the Beef

Heat vegetable oil in a large skillet or wok over medium-high heat. Add the beef in batches, searing each side until browned. Remove and set aside.

Step 4: Make the Sauce

In the same pan, reduce heat to medium and add garlic and ginger. Sauté until fragrant, then pour in soy sauce and brown sugar. Stir until the sugar dissolves and the sauce begins to bubble.

Step 5: Combine Everything

Add cooked beef back to the pan along with red bell peppers. Toss for a few minutes until the peppers soften slightly. Add noodles and toss to coat with sauce. Finish with chopped green onions.

Serving and Storing Your Mongolian Beef Noodles

Serve the noodles hot, straight from the pan, for best texture. If you have leftovers, store them in an airtight container in the fridge for up to 3 days. Reheat in a skillet with a splash of water or broth to loosen the sauce. This dish does not freeze well due to the texture change in noodles.
