Ingredient Breakdown

Flank Steak

Flank steak provides:

  • Tender texture
  • Rich beef flavor
  • Quick cooking time

When sliced thinly against the grain, it becomes incredibly tender.

Noodles

Noodles add:

  • Hearty texture
  • Sauce absorption
  • Satisfaction

Lo mein noodles work best, but spaghetti can be used in a pinch.

Soy Sauce

Soy sauce contributes:

  • Umami flavor
  • Saltiness
  • Rich color

It forms the backbone of the sauce.

Brown Sugar

Brown sugar adds:

  • Sweetness
  • Balance
  • Caramel notes

It creates the signature Mongolian flavor profile.

Garlic and Ginger

These aromatics provide:

  • Warmth
  • Depth
  • Authentic Asian-inspired flavor

Equipment Needed

  • Large skillet or wok
  • Large pot
  • Mixing bowls
  • Tongs
  • Measuring cups and spoons

Step 1: Prepare the Beef

Slice the beef into thin strips.

Place in a bowl and toss with:

  • 2 tablespoons cornstarch
  • ½ teaspoon black pepper

Let sit for:

10 minutes

This helps create a tender texture and allows the sauce to cling to the meat.

Why Use Cornstarch?

Cornstarch helps:

  • Tenderize the beef
  • Create a silky coating
  • Thicken the sauce later

It’s a simple restaurant-style technique.

Step 2: Cook the Noodles

Bring a large pot of salted water to a boil.

Cook:

  • 12 oz noodles

according to package directions.

Drain and set aside.

Toss lightly with a few drops of oil to prevent sticking.

Step 3: Prepare the Sauce

In a bowl combine:

  • Soy sauce
  • Brown sugar
  • Beef broth
  • Garlic
  • Ginger
  • Hoisin sauce
  • Sesame oil

Whisk until smooth.

In a separate small bowl combine:

  • 2 tablespoons cornstarch
  • 3 tablespoons water

to create a slurry.

Step 4: Sear the Beef

Heat:

  • 1 tablespoon vegetable oil

in a large skillet or wok over high heat.

Add the beef in batches.

Cook for:

2–3 minutes per batch

until browned.

Transfer to a plate.

Why Cook in Batches?

Overcrowding the pan causes the beef to steam rather than sear.

Cooking in batches ensures:

  • Better browning
  • More flavor
  • Better texture

Step 5: Cook the Sauce

Pour the sauce mixture into the skillet.

Bring to a gentle simmer.

Cook for:

2–3 minutes

until the sugar dissolves.

Add the cornstarch slurry.

Whisk continuously.

The sauce will thicken into a glossy consistency.

Step 6: Return the Beef

Add the cooked beef back to the skillet.

Stir well.

Allow it to simmer for:

2 minutes

so the beef absorbs the flavors.

Step 7: Add the Noodles

Add the cooked noodles.

Using tongs, toss everything together.

Continue tossing until:

  • Noodles are coated
  • Sauce is evenly distributed
  • Beef is mixed throughout

What Makes This Dish Special?

The noodles absorb the rich Mongolian sauce, creating a dish where every bite is packed with flavor instead of just coating the beef.

Step 8: Garnish

Sprinkle with:

  • Green onions
  • Sesame seeds

Serve immediately.
