Juicy Mongolian Beef Inspired by Chinese Takeout

Introduction

If you’re craving that sweet, savory, and slightly sticky stir-fry from your favorite Chinese takeout spot, this Juicy Mongolian Beef delivers all the flavor—without leaving your kitchen. With tender strips of beef, caramelized garlic, and a glossy soy-based sauce, it’s no wonder Mongolian beef has become a takeout classic.

Originally popularized by Chinese-American restaurants (not traditional Mongolian cuisine), this dish features a beautifully seared beef, usually flank steak, coated in a soy, brown sugar, and ginger sauce. It’s fast, bold, and comforting, making it a go-to for weeknight dinners or meal prep.

Ready in under 30 minutes and made in one pan, it’s a juicy, flavorful stir-fry you’ll want to put on repeat.

Ingredients Overview

The beauty of Mongolian beef lies in its simplicity and the contrast between tender meat and rich sauce. Here’s what you’ll need:

Key Ingredients

Flank steak:
Thinly sliced against the grain for tenderness. Flank is ideal, but sirloin or skirt steak works too.
Cornstarch:
Lightly coating the beef with cornstarch gives it that signature crispy-edged texture and helps thicken the sauce.
Garlic and ginger:
Fresh is best. They bring aromatic heat and depth to balance the sweetness.
Soy sauce:
Use low-sodium soy sauce to prevent overpowering saltiness.
Brown sugar:
Creates the signature glossy, sticky sauce with a hint of sweetness.
Water:
Helps loosen the sauce without diluting flavor.
Green onions (scallions):
Stirred in at the end for crunch and freshness.
Sesame oil (optional):
A few drops add nutty richness.

Ingredient Substitutions

Gluten-free: Use tamari or coconut aminos instead of soy sauce.
Low sugar: Cut brown sugar to 2 tablespoons or swap with monk fruit sweetener.
Vegetable swap: Add broccoli, snow peas, or bell peppers for extra nutrients.
Protein alternative: Try it with chicken, tofu, or shrimp using the same technique.

Step-by-Step Instructions

1. Prepare the Beef

Slice your flank steak thinly (about 1/4 inch) against the grain to maximize tenderness. Pat dry with paper towels.

Toss the beef in 2 tablespoons of cornstarch, coating evenly. Let it rest for 10–15 minutes while you prep the sauce. This creates a crispy sear and helps thicken the final glaze.

2. Mix the Sauce

In a small bowl, whisk together:

½ cup low-sodium soy sauce
⅓ cup brown sugar
½ cup water
1 tbsp grated fresh ginger
3 cloves garlic, minced

Set aside.

3. Sear the Beef

Heat 1–2 tablespoons of oil in a large skillet or wok over medium-high heat.

Add the beef in a single layer (work in batches if needed) and sear for 2–3 minutes per side until browned and just cooked. Remove and set aside.

Tip: Don’t overcrowd the pan or the beef will steam instead of sear.

4. Make the Sauce

In the same pan, reduce heat slightly and pour in the sauce mixture. Stir and bring to a simmer. Cook for 2–3 minutes until the sauce thickens slightly.

Return the beef to the pan and toss to coat evenly in the sauce.
Add green onions and stir for another 1–2 minutes just until softened.

5. Finish and Serve

Drizzle with a touch of sesame oil if using. Serve hot over steamed rice, jasmine rice, or stir-fried noodles.

Optional toppings: sesame seeds, chili flakes, or fresh cilantro.

Tips, Variations & Substitutions

Cooking Tips
