Savory, saucy, and absolutely packed with flavor, Mongolian Beef Noodles are a comfort food dream come true. This dish brings together tender strips of beef, chewy noodles, and a glossy, garlicky soy-based sauce that clings to every bite. The bold umami richness is balanced with hints of sweetness, making it irresistible from the very first forkful.

Inspired by the classic Mongolian beef dish you’ll find at many Asian restaurants, this noodle version adds a satisfying carb twist that turns it into a full meal. Quick enough for a weeknight but indulgent enough for a special dinner, Mongolian Beef Noodles are a perfect mix of ease and elegance that delivers on every level.

Why You’ll Love This Mongolian Beef Noodles

This dish is the definition of crave-worthy. It cooks in under 30 minutes, requires simple pantry ingredients, and delivers restaurant-quality flavor at home. The noodles soak up the savory sauce beautifully, and the seared beef adds richness and depth. It’s also versatile: you can toss in extra veggies or adjust the spice level to your liking.

What Kind of Noodles Should I Use?

You can use a variety of noodles for this dish, but lo mein noodles or udon noodles work best due to their chewy texture and ability to absorb sauce. If you can’t find either, spaghetti or linguine can be a solid substitute. Just be sure to avoid overly thin noodles like vermicelli, which won’t hold up as well with the hearty beef and sauce.

Ingredients for the Mongolian Beef Noodles

Each ingredient in this dish plays a key role in building layers of flavor and texture:

• Beef (flank steak or sirloin): Thinly sliced beef provides a juicy, tender bite that soaks up the savory sauce perfectly.
• Lo mein or udon noodles: These thick, chewy noodles are ideal for catching every bit of the flavorful Mongolian sauce.
• Soy sauce (low sodium): Adds that essential salty umami base to the sauce.
• Dark soy sauce: Provides deeper color and a more robust flavor.
• Brown sugar: Balances the salty soy sauce with a touch of caramelized sweetness.
• Garlic & Ginger: Fresh aromatics that bring warmth and depth.
• Cornstarch: Used to coat the beef and thicken the sauce, giving it that signature glossy finish.
• Green onions: Add freshness and crunch, sprinkled on top for contrast.
• Red bell pepper (optional): Brings a pop of color and sweetness.
• Sesame oil: A finishing touch that adds a toasty, nutty aroma.
• Vegetable oil: For searing the beef and stir-frying.

How To Make the Mongolian Beef Noodles

Step 1: Prep and Slice

Slice the beef thinly against the grain and toss it in cornstarch. Let it sit for 10 minutes to tenderize and help it crisp up during cooking.

Step 2: Cook the Noodles

Boil your noodles according to package directions. Drain and set aside. Drizzle with a touch of oil to keep them from sticking.

Step 3: Make the Sauce

In a bowl, mix soy sauce, dark soy sauce, brown sugar, minced garlic, and grated ginger. Set it aside.

Step 4: Sear the Beef

Heat oil in a skillet over high heat. Sear the beef in batches until browned and just cooked through. Remove and set aside.

Step 5: Stir-Fry and Combine

In the same pan, stir-fry red bell pepper (if using) for 2 minutes. Add the cooked noodles, beef, and sauce. Toss everything together until the noodles are evenly coated.

Step 6: Garnish and Serve

Top with chopped green onions and a drizzle of sesame oil before serving.
