Step-by-Step Instructions
Preparing the Flank Steak
To start, you need to slice the flank steak thin. Cutting against the grain helps make it tender. After slicing, place the beef in a medium bowl. Add 2 tablespoons of cornstarch. Toss until the meat is well-coated. This step helps create a nice crust when cooking. Let the beef sit for about 10 minutes. This allows the cornstarch to work its magic.
Cooking the Beef to Perfection
Next, heat 2 tablespoons of vegetable oil in a large skillet or wok over medium-high heat. Once the oil is hot, add the coated beef to the pan. Cook the beef for 5 to 7 minutes. You want it to turn brown and crispy. Stir it often to ensure even cooking. When done, remove the beef and set it aside on a plate.
Making the Flavorful Sauce
In the same skillet, add the white parts of 4 chopped green onions, 4 minced garlic cloves, and 1 tablespoon of grated ginger. Stir-fry these ingredients for 1 to 2 minutes. This step brings out their rich flavors. In a separate mixing bowl, combine ½ cup of low-sodium soy sauce, ¼ cup of brown sugar, 1 tablespoon of rice vinegar, and 1 teaspoon of sesame oil. If you like heat, add ½ teaspoon of crushed red pepper flakes. Pour this sauce into the skillet and let it simmer. After a minute, return the cooked beef to the skillet. Toss the beef until it’s evenly coated with the sauce. Cook it for another 2 to 3 minutes. Finally, stir in the green parts of the chopped green onions and remove the skillet from heat.
Pro Tips
- Perfectly Tender Beef: To achieve tender meat, always slice flank steak against the grain and let it marinate with cornstarch for at least 10 minutes.
- High Heat Cooking: Use a hot skillet or wok to ensure the beef gets a nice sear and crispy texture. Don't overcrowd the pan, or the beef will steam instead of fry.
- Flavor Boost: For a deeper flavor, consider adding a splash of Shaoxing wine or dry sherry to the sauce. It enhances the umami profile significantly.
- Garnish for Presentation: Always finish with fresh green onions and a sprinkle of sesame seeds. This not only adds visual appeal but also enhances the dish's flavor and texture.
Tips & Tricks
Best Cooking Techniques for a Crispy Finish
To get crispy beef, start with cornstarch. Toss the sliced flank steak in cornstarch. This helps create a nice crust. Let the beef sit for about 10 minutes. This makes it tender and allows the coating to stick. When cooking, use a hot skillet or wok. Make sure the oil is very hot before adding the beef. Cook the beef in batches if needed. This prevents overcrowding and keeps it crispy.
How to Achieve Maximum Flavor
For great flavor, use fresh ingredients. Fresh garlic and ginger add a lot. Don’t skip the soy sauce; it gives depth. Brown sugar adds sweetness and balance. If you want heat, add crushed red pepper flakes. Mix the sauce well before adding it to the beef. Let everything simmer together. This helps the beef soak up all the flavors.
Common Mistakes to Avoid
One common mistake is not letting the beef sit after coating it. This can lead to chewy meat. Another mistake is cooking the beef for too long, making it tough. Avoid using too much sauce; it can overpower the dish. Finally, don’t forget to stir in the green onions at the end. This adds a fresh touch and enhances the flavor.

Variations
Mongolian Beef with Additional Vegetables
You can easily add vegetables to your Mongolian beef. This not only adds color but also boosts nutrition. Good choices include bell peppers, broccoli, or snap peas. Start by slicing the veggies thin. Add them to the skillet when you stir-fry the garlic and ginger. Cook them for about 2-3 minutes. This timing keeps the veggies crisp and bright. Toss the beef back in with the sauce. You’ll have a colorful and tasty dish.
Spicy Mongolian Beef Option
If you love heat, make your Mongolian beef spicy. Simply add more crushed red pepper flakes to the sauce. You can also include fresh sliced chilies. For a smoky flavor, try adding a dash of chili oil. Mix it in when you add the sauce to the skillet. This will bring a nice kick without overpowering the dish. Adjust the spice level to your taste. Enjoy the extra warmth in each bite.
Vegetarian or Vegan Alternatives
You can create a vegetarian or vegan version of Mongolian beef. Use tofu or tempeh as a protein substitute. First, press and cube the tofu. Sauté it in the skillet until golden brown. Then follow the same steps for the sauce and veggies. For a heartier option, consider using seitan. It has a chewy texture that mimics beef well. Make sure to keep the sauce vegan by using a plant-based soy sauce. This version is just as delicious and satisfying!
Storage Info
How to Store Leftovers
To keep your Mongolian beef fresh, store it in an airtight container. Make sure it cools down first. Place it in the fridge within two hours of cooking. It will last for about three to four days. If you want to save it longer, consider freezing.
Reheating Instructions for Maximum Freshness
When you're ready to enjoy your leftovers, reheat them gently. You can use a microwave or a skillet. If using a microwave, cover the container to keep moisture in. Heat in 30-second bursts until warm. If using a skillet, add a splash of water to keep it from drying out. Stir frequently over medium heat until heated through.
Freezing Guidance and Tips
If you want to freeze your Mongolian beef, do it right after cooking. Use a freezer-safe container. It can last for about three months in the freezer. When you're ready to eat, thaw it overnight in the fridge. Reheat as mentioned above. Avoid refreezing after it has been thawed. Enjoy your tasty meal later!
