Mongolian beef is a Chinese‑restaurant dish made with thinly sliced beef that’s stir‑fried and coated in a sweet, savory sauce typically flavored with soy sauce, garlic, ginger, and a bit of sugar, then finished with green onions for freshness and aroma. Despite the name, it is not a traditional dish from Mongolia; it was created in Taiwan in the mid‑20th century, emerging from “Mongolian barbecue”–style restaurants where diners chose meats, vegetables, and sauces to be stir‑fried on a large griddle.
From there, Mongolian beef spread to Chinese‑American restaurants, where it became a popular menu staple and a familiar example of Chinese‑American takeout cuisine. Now that you have this recipe, you can easily make it at home in just about 30 minutes, so it’s perfect for busy weeknight dinners!

Ingredients You’ll Need for Mongolian Beef
- 1 lb flank steak, thinly sliced
- 1 teaspoon soy sauce
- 1 teaspoon oil
- ¼ teaspoon baking soda
- ½ cup reduced-sodium soy sauce
- 1 tablespoon oyster sauce
- 2 tablespoons water
- 2 tablespoons brown sugar
- 1 teaspoon toasted sesame oil
- ½ cup cornstarch
- Pinch of salt
- Pinch of black pepper
- 3 tablespoons oil, for frying (more as needed)
- 1½ teaspoon minced garlic
- 1 teaspoon ginger paste (or 1 tablespoon freshly grated ginger)
- Green onions, chopped, for garnish
- Sesame seeds, chili flakes (optional, for heat)
Step-by-Step Instructions
Step 1: Marinate the Beef
Place your thinly sliced flank steak in a bowl and add 1 teaspoon soy sauce, 1 teaspoon oil, and ¼ teaspoon baking soda. Mix well and let it marinate for 15–30 minutes. This helps tenderize the beef and enhance flavor.
Step 2: Prepare the Sauce
In a small bowl, whisk together ½ cup reduced-sodium soy sauce, 1 tablespoon oyster sauce, 2 tablespoons water, 2 tablespoons brown sugar, and 1 teaspoon sesame oil. This is your flavorful Mongolian beef sauce. Adjust the salt or sweetness to suit your taste.
Step 3: Coat the Beef
Mix ½ cup cornstarch with a pinch of salt and pepper. Add the marinated beef and toss until every slice is well-coated. This coating creates that signature crispiness when fried.
Step 4: Fry Until Crispy
Heat 3 tablespoons of oil in a large skillet or wok over medium-high heat. Spread the beef in a single layer and cook in batches for 1–2 minutes per side, just until golden and crisp. Avoid overcrowding the pan — this helps the beef stay crispy. Transfer cooked beef to a paper towel-lined plate to remove excess oil.
Step 5: Make the Sauce Base
In the same pan, add more oil if necessary, and sauté minced garlic and ginger for about a minute, just until fragrant. Pour in your soy sauce mixture and bring it to a gentle boil.
Step 6: Combine and Coat
Return the fried beef to the skillet and toss to coat. Cook for another 1–2 minutes until the sauce thickens into a glossy glaze and clings to every piece.
Step 7: Serve and Garnish
Serve this Mongolian Beef with rice or noodles. Top with chopped green onions, sesame seeds, and chili flakes for a pop of color and extra flavor.
Tips for the Best Mongolian Beef
- Slice thinly: Place the beef in the freezer for 20 minutes before slicing for thin, even cuts.
- Don’t overcook: Quick frying keeps the edges crisp while keeping the inside tender.
- Use fresh ginger and garlic: They give a more authentic, aromatic flavor.
- Double the sauce: Love extra glaze on your rice? Make 1.5 times the sauce mixture.
Storage and Reheating Tips
- Refrigerate: Store leftovers in an airtight container for up to 3 days.
- Reheat: Warm in a skillet over medium heat until the sauce reactivates. Avoid microwaving too long—it can make the beef soggy.
- Freeze: You can freeze cooked Mongolian Beef (without garnishes) for up to a month. Thaw overnight before reheating.
