Mongolian Beef Stir-Fry is the kind of dish that makes you wonder why you ever ordered takeout. Thinly sliced beef caramelized in a sweet and savory sauce, tossed with crisp green onions, and served over rice—this dish is pure comfort with bold flavors.
It comes together in minutes, making it perfect for busy nights when you want something flavorful but don’t have hours to spend in the kitchen. The key to its rich taste? A perfectly balanced sauce made from soy sauce, brown sugar, garlic, and ginger that thickens into a glossy coating around each piece of beef.
Unlike restaurant versions that can be overly sweet, this homemade Mongolian beef lets you control the balance of flavors. Whether you like it a little spicier, extra saucy, or loaded with vegetables, it’s easy to customize.
What Makes This Stir-Fry So Good?
Every great Mongolian beef dish starts with the right ingredients. Here’s what makes this one stand out:
- Thinly Sliced Beef – Flank steak or sirloin works best. The thin slices cook quickly and soak up all the sauce.
- Garlic and Ginger – These add bold aromatics and depth to the sauce.
- Soy Sauce and Brown Sugar – The perfect mix of salty and sweet that caramelizes beautifully.
- Cornstarch – Helps create a crispy crust on the beef while also thickening the sauce.
How to Make Mongolian Beef Stir-Fry
- Slice and Coat the Beef – Thinly slice the beef against the grain and toss it with cornstarch. Let it sit for a few minutes—this helps create that crispy texture when cooked.
- Prepare the Sauce – In a bowl, mix soy sauce, brown sugar, garlic, ginger, and a little water. Set aside.
- Cook the Beef – Heat oil in a wok or skillet over high heat. Cook the beef in batches until browned and crispy on the edges. Remove and set aside.
- Simmer the Sauce – Pour the sauce into the pan, letting it bubble and thicken. Add the cooked beef back in and toss everything together.
- Finish with Green Onions – Stir in sliced green onions for a fresh contrast to the rich sauce. Serve hot over rice or noodles.
Easy Ways to Customize It
Mongolian beef is already packed with flavor, but you can tweak it to match your preferences:
- Make It Spicy – Add red pepper flakes or a drizzle of sriracha for some heat.
- Use Chicken Instead – Swap the beef for sliced chicken breast or thighs for a lighter version.
- Add Vegetables – Broccoli, bell peppers, or snap peas work great in this stir-fry.
- Go Low-Carb – Serve over cauliflower rice or zucchini noodles instead of white rice.
Why This Recipe Works Every Time
This dish comes together fast, but every step is designed to bring out maximum flavor:
- Perfectly Crispy Beef – The cornstarch coating helps the beef crisp up before it gets coated in the sauce.
- Balanced Sweet-Savory Sauce – Just the right mix of soy sauce, brown sugar, and aromatics keeps it from being too sweet.
- Quick and Easy – From start to finish, it takes less than 30 minutes.
