What Is Mongolian Beef?
Despite its name, Mongolian Beef didn’t originate in Mongolia. It’s a Chinese-American fusion dish that became popular through Asian-American restaurants, particularly P.F. Chang’s. The dish is known for its sweet-salty soy glaze, thinly sliced tender beef, and lightly crisp edges — all tossed in a glossy sauce that clings perfectly to each piece.
The secret lies in the balance of textures and flavors: slightly crunchy exterior, melt-in-your-mouth interior, and a sauce that’s both savory and subtly sweet.

| Ingredient | Purpose | Smart Substitutions |
|---|---|---|
| Flank steak | Tender yet flavorful cut for quick searing | Skirt steak, sirloin, or thin-sliced ribeye |
| Cornstarch | Creates velvety texture & seals juices | Arrowroot powder (gluten-free) |

💡 Chef’s Tip: Slice beef against the grain, about ⅛ inch thick, to ensure tenderness.
Step-by-Step Instructions (With Chef’s Tips)
1. Prepare the Beef
- Slice flank steak thinly against the grain.
- Toss in 2 tablespoons cornstarch and let sit 10 minutes.
🔬 Science: The cornstarch forms a micro-layer that locks in moisture and enhances browning — a technique called velveting.
2. Make the Sauce
- In a bowl, whisk together:
- ½ cup soy sauce
- ½ cup water
- ¼ cup brown sugar
- 1 teaspoon minced ginger
- 2 cloves minced garlic
Optional: Add ½ tsp red pepper flakes for mild heat.
3. Sear the Beef
- Heat 2 tablespoons oil in a wok or skillet until hot (not smoking).
- Add beef in a single layer, cook 30–60 seconds per side until browned.
- Remove beef; don’t overcrowd the pan.
⚡ Pro Tip: High heat = crisp exterior, tender inside. Overcrowding steams the beef — avoid it.
4. Create the Glaze
- In the same pan, pour in the sauce.
- Simmer 2–3 minutes until slightly thickened.
- Return beef to the pan, toss until coated and glossy.
5. Finish & Serve
- Add sliced green onions just before serving.
- Serve immediately over steamed rice, noodles, or cauliflower rice for a low-carb option.
Expert Tips for Perfect Texture & Sauce
- Use dry beef: Pat slices with paper towels before cooking — moisture kills the sear.
- Control your sugar: Sweetness should enhance, not dominate. Adjust by 1 tbsp at a time.
- Pan material matters: Carbon steel or cast iron provides ideal heat retention.
- Rest the beef: Let cooked beef sit 2 minutes before serving for maximum juiciness.
- Double the sauce: It’s so good, you’ll want extra for rice or vegetables.
Serving Suggestions & Pairings
Pair your Mongolian Beef with:
- Steamed jasmine rice or garlic fried rice
- Stir-fried broccoli, bok choy, or snap peas
- Pickled cucumber salad for a refreshing contrast
- A sprinkle of toasted sesame seeds for texture
🍶 Beverage pairing: green tea, plum wine, or a light sparkling water with citrus.

Common Questions (FAQs)
Q1: Can I use chicken instead of beef?
Absolutely. Use boneless chicken thighs or breasts; cooking time may vary slightly.
Q2: Why is my beef tough?
Overcooking or slicing with the grain can make beef chewy. Always slice against the grain and cook quickly on high heat.
Q3: Can I make this without cornstarch?
Yes. Use arrowroot or tapioca starch for similar results, or skip it for a lighter sauce.
Q4: Can I make this ahead of time?
You can prep the sauce and beef separately up to 24 hours in advance — then cook fresh for best results.
