What Kind of Noodles Should I Use for Mongolian Beef Noodles?

Lo mein noodles or thick udon noodles work best, but you can easily substitute with spaghetti or linguine if that’s what you have on hand. The key is to use a noodle that holds up to the sauce without turning mushy.

Ingredients for the Mongolian Beef Noodles

8 oz flank steak, thinly sliced against the grain
2 tablespoons cornstarch
2 tablespoons vegetable oil
3 garlic cloves, minced
1 tablespoon fresh ginger, grated
1/3 cup soy sauce
1/4 cup brown sugar
1/4 cup water
1 tablespoon hoisin sauce
8 oz lo mein or udon noodles, cooked and drained
1/2 cup green onions, sliced
1 teaspoon sesame oil (optional)
Sesame seeds and red pepper flakes for garnish

How To Make the Mongolian Beef Noodles

Step 1: Prepare the Beef

Toss the thinly sliced flank steak with cornstarch until evenly coated. Let it sit for 10 minutes to help create a crispy texture when seared.

Step 2: Sear the Beef

Heat vegetable oil in a large skillet or wok over medium-high heat. Add the beef in a single layer and cook until browned and crispy on both sides. Remove and set aside.

Step 3: Make the Sauce

In the same pan, add garlic and ginger. Sauté for 30 seconds until fragrant. Stir in soy sauce, brown sugar, water, and hoisin sauce. Bring to a simmer and cook for 2-3 minutes until slightly thickened.

Step 4: Combine Everything

Add the cooked noodles and beef back into the pan. Toss well to coat everything in the sauce. Stir in green onions and drizzle with sesame oil if using.

Step 5: Garnish and Serve

Top with sesame seeds and a pinch of red pepper flakes for extra kick. Serve immediately while hot.

How to Serve and Store Mongolian Beef Noodles

Serve these noodles hot, straight from the skillet. They’re delicious on their own or with a side of steamed broccoli or bok choy for added greens. For a complete meal, pair with a simple cucumber salad or miso soup.

Leftovers store beautifully! Place in an airtight container and refrigerate for up to 3 days. Reheat in a skillet or microwave, adding a splash of water or soy sauce to refresh the noodles.

Frequently Asked Questions

How thin should I slice the beef?

Slice as thin as possible against the grain. This ensures the beef cooks quickly and remains tender.

Can I use ground beef instead?

Yes, ground beef is a quicker alternative. Cook it until browned, then proceed with the sauce and noodles.

Is this recipe spicy?

Not by default, but you can add chili garlic sauce or extra red pepper flakes to turn up the heat.

Can I use gluten-free noodles?

Absolutely. Rice noodles or any gluten-free pasta can work. Just keep an eye on cooking times.

What vegetables can I add?

Try bell peppers, snow peas, shredded carrots, or baby spinach—toss them in with the sauce to slightly wilt.
