What Are Mongolian Beef Noodles?

Origins of Mongolian Beef

Despite the name, Mongolian beef isn’t actually Mongolian. This flavorful stir-fry is more of a Taiwanese-American creation, often found at American Chinese restaurants. It’s known for its sweet and savory sauce, tender beef, and quick cooking time, making it perfect for busy weeknights.

Key Ingredients That Define the Dish

This Mongolian noodles recipe uses:

Lean ground beef instead of the traditional flank steak for a quicker cooking time.
Dark soy sauce, hoisin sauce, and brown sugar to build that signature sweet sauce.
Fresh ginger and garlic cloves for bold flavor.
Green beans and green onions to add texture and freshness.

Why This Dish Is a Weeknight Favorite

This recipe uses pantry staples, cooks in one large nonstick skillet, and comes together in under 30 minutes. The whole family loves it, and it’s endlessly customizable based on whatever frozen veggies you need to use up. That alone is a good reason to keep this one in the regular dinner rotation.

Choosing the Right Noodles for Mongolian Beef

Best Noodle Options

You’ve got choices when it comes to the noodles:

Udon noodles (my pick!) are thick, chewy, and perfect for soaking up every bit of the flavorful sauce. Find them in the freezer section of your grocery store.
Ramen noodles are a great pantry backup—quick and cheap.
Rice noodles are gluten-free and lighter.
Lo mein or spaghetti can work in a pinch, too.

Each brings a slightly different texture, so pick what you like best or what you already have in your pantry.

Gluten-Free and Low-Carb Alternatives

You can sub in zucchini noodles or cabbage ribbons if you want something lower in carbs. Just keep that sauce mixture rich and flavorful to compensate for the swap.

Cooking Tips for Perfect Noodles

Always cook your noodles according to package directions, then rinse with cold water to stop the cooking. This helps prevent mushy noodles and gives you that ideal, tender noodle bite.

How to Make Mongolian Ground Beef Noodles

Ingredients

1 pkg of udon noodles
1 lb lean ground beef
1/2 tsp black pepper
1/2 tsp sesame oil
3/4 cup frozen green beans
2 garlic cloves, minced
1/4 tsp fresh ginger, grated
1/4 cup brown sugar
1/4 tsp red pepper flakes
1/3 cup hoisin sauce
1/3 cup dark soy sauce or liquid aminos for a lower sodium option
2/3 cup beef broth
1 tsp cornstarch
Garnish: green onions and sesame seeds

Step-by-Step Cooking Instructions

Cook noodles according to package directions. Rinse in cold water and set aside. If using frozen udon noodles, they are fully cooked. Just add them into the pan at the end of cooking to thaw and heat up.
In a large skillet, brown the ground beef over medium heat. Drain any excess grease. Season with black pepper.
Add sesame oil, green beans, garlic cloves, and fresh ginger. Saute the beef with the green beans until they are just tender.

Whisk together dark soy sauce (or liquid aminos) and cornstarch in a small bowl. Pour into the skillet.
Add brown sugar, hoisin sauce, beef broth, and red pepper flakes. Stir everything together over medium-high heat until the sauce thickens.

Add the cooked noodles to the skillet and stir well to coat in the sauce. For frozen udon noodles, nestle them down into the pan, cover them, and allow them to thaw for a few minutes. When they are thawed, you can easily stir them into the dish.
Garnish with chopped green onions and sesame seeds. Serve and enjoy!

Pro Tip: Want a little bit of extra heat? Add more red pepper flakes or a spoonful of chili paste.

Variations and Customizations

Protein Swaps: Try ground turkey, thin-sliced flank steak, or cubed tofu for a different spin.
Veggie Add-Ins: This is the best way to use up leftover veggies! Toss in bell peppers, shredded carrots, or even broccoli.
Adjusting the Sweetness or Spice: Cut the brown sugar in half if you prefer a less sweet sauce. Add more red pepper flakes or fresh chili peppers for extra heat.

Storage, Reheating, and Make-Ahead Tips

Meal Prep Friendly: You can cook the noodles and beef mixture in advance. Store separately in airtight containers and combine just before reheating for the best texture.
How to Store Leftovers: Allow leftovers to cool to room temperature. Then, store in an airtight container in the fridge for up to 4 days. This is one of those noodle bowls that tastes even better the next day.
Reheating Tips: Reheat in a skillet over medium heat with a splash of beef broth to loosen the sauce and prevent sticking. You can also microwave it in 30-second increments, stirring after each until it reaches the desired temperature.

Quick Summary: This Mongolian beef stir-fry is fast, customizable, and makes delicious leftovers. Keep frozen veggies and udon noodles on hand for an easy weeknight win.

Serving Suggestions

Serve alongside spring rolls or a crisp Asian salad.
Pair with chili garlic edamame for a little crunch.
Sip on green tea or a light white wine for a refreshing balance.

FAQs about Mongolian Beef Noodles

Yes! Just cook them according to the package. Ramen will give a thinner, softer noodle texture, but it still works great with the sauce.

Sub in a mix of peanut butter, soy sauce, and a touch of honey or molasses to mimic the sweet-savory flavor.

You can freeze the beef and sauce mixture, but I recommend cooking fresh noodles next time for the best texture.
