I love using flank steak for this dish. It cooks quickly and has great flavor. The cornstarch helps the beef get crispy. You want that nice crunch! Vegetable oil is best for frying. It can take high heat well.
Green onions give this dish a fresh taste. Be sure to chop both the white and green parts. Garlic and ginger add depth to the flavor. They bring warmth and spice.
For the sauce, soy sauce and brown sugar create a sweet and savory balance. Sesame oil adds that nutty taste we all love. Red pepper flakes bring a bit of heat, but you can skip them if you want.
Suggested Equipment
- Large skillet or wok
- Mixing bowls
- Whisk
Using a large skillet or wok helps cook the beef evenly. Mixing bowls are great for tossing the meat with cornstarch. A whisk is key for blending your sauce smoothly.

Step-by-Step Instructions
Preparing the Beef
- Toss the thinly sliced flank steak with cornstarch in a mixing bowl.
- Let it sit for 15 minutes. This step helps the beef absorb the cornstarch.
Cooking the Beef
- Heat 2 tablespoons of vegetable oil in a skillet over medium-high heat.
- Add the coated beef in a single layer. Brown it for 3-4 minutes on each side.
Making the Sauce
- In the same skillet, add 1 tablespoon of oil.
- Sauté the chopped white parts of the green onions, minced garlic, and grated ginger for about 1 minute. This will make your kitchen smell amazing!
- In a separate bowl, whisk together soy sauce, brown sugar, sesame oil, and red pepper flakes if you want some heat.
- Pour this sauce mix into the skillet, then add 1/4 cup of water. Stir well and bring it to a simmer.
Final Steps
- Return the browned beef to the skillet. Stir it well to coat the beef with the sauce.
- Let it simmer for 3-4 minutes. This thickens the sauce and combines the flavors.
- Stir in the chopped green onion greens and cook for an additional minute.
- Remove from heat and let it rest for a minute before serving.
Serve this flavorful dish over steamed white or fried rice. Garnish with more green onions and sesame seeds for some added flair!
Tips & Tricks
Perfecting the Flavors
To achieve that perfect brown color on your beef, coat it with cornstarch. This layer helps create a nice crust during cooking. Use high heat when cooking the beef. This step ensures that the meat gets crispy. Let the beef rest after cooking. Resting time allows the juices to settle back into the meat, making it tender and juicy.
Cooking Techniques
Stir-frying is key for this dish. It cooks the beef quickly while keeping it moist. Sautéing might not give you the same crispy texture. Always maintain high heat when cooking. This method keeps the beef from steaming and helps it brown.
Ingredient Substitutions
If you cannot find flank steak, use sirloin or ribeye instead. Both options work well and have great flavor. For a lower sodium option, you can use low-sodium soy sauce. It gives you the same taste without too much salt.
Pro Tips
- Slice Against the Grain: Always slice the flank steak against the grain to ensure tender bites. This technique breaks down the muscle fibers, making the meat easier to chew.
- Let the Meat Rest: After cooking, let the Mongolian beef rest for a couple of minutes before serving. This allows the flavors to meld and the juices to redistribute, enhancing the overall taste.
- Adjust the Sweetness: Feel free to adjust the amount of brown sugar based on your taste preference. If you enjoy a sweeter sauce, add a bit more, but taste as you go to avoid overpowering the dish.
- Garnish for Flavor: Don't skip the garnish! Adding chopped green onions and sesame seeds not only enhances the presentation but also adds an extra layer of flavor and texture to the dish.
Variations
Spice It Up
To make your Mongolian beef even more exciting, consider adding more heat. You can do this by:
- Adding more red pepper flakes: Increase the amount to suit your taste. A little more can make a big difference.
- Incorporating chili oil: Drizzle some chili oil into your sauce for a rich flavor and extra spice.
These simple tweaks can enhance the dish and give it a kick that you may love.
Vegetable Additions
Adding vegetables can boost texture and nutrients. Here are some great options:
- Bell peppers and broccoli: These colorful veggies add crunch and a fresh taste. Slice them thin and toss them in during the last few minutes of cooking.
- Snap peas or carrots: Both bring a natural sweetness and pair well with the beef. Add them early on to keep them crisp.
Feel free to mix and match based on what you have at home or your favorite flavors.
Different Proteins
If you're looking for variety, try different proteins. Options include:
- Using chicken or tofu: For a lighter meal, chicken works well, while tofu is a great vegetarian choice. Cut them into bite-sized pieces and follow the same cooking steps.
- Vegetarian alternatives: You can also use tempeh or seitan for a hearty meat substitute.
These variations can cater to different diets while keeping the dish flavorful and satisfying.
Storage Info
Refrigeration
To keep your Mongolian beef fresh, store leftovers in an airtight container. Let the dish cool down before sealing it. This helps to prevent moisture buildup. Place it in the fridge within two hours of cooking. The beef will stay good for up to three days. When ready to eat, just reheat it in a skillet or microwave until warm.
Freezing
To freeze Mongolian beef, first, let it cool completely. Then, place it in a freezer-safe container or bag. Make sure to remove as much air as possible to prevent freezer burn. You can freeze it for up to three months. To reheat, thaw it overnight in the fridge. Then, warm it up in a skillet over low heat. Add a splash of water or broth to keep it moist.
Shelf Life
Mongolian beef is best enjoyed fresh but can last in the fridge for three days. If frozen, it can stay fresh for three months. After that, the quality may decline. Always check for off smells or changes in texture before eating leftovers.
FAQs
Can I make this dish gluten-free?
Yes, you can make Mongolian beef gluten-free. Use gluten-free soy sauce instead of regular soy sauce. Brands like Tamari or Coconut Aminos work great. Check your cornstarch too; most are gluten-free, but always read the label.
What side dishes pair well with Mongolian Beef?
Mongolian beef goes well with a few sides. Here are some ideas:
- Steamed white rice
- Fried rice
- Stir-fried vegetables such as bell peppers and broccoli
- Snap peas or carrots for a fresh crunch
These sides balance the rich flavors of the beef.
How can I make Mongo Beef less sweet?
To reduce sweetness, cut back on the brown sugar. Try using only 1/4 cup instead of 1/2 cup. You can also add more soy sauce to balance the taste. If you want, add a splash of rice vinegar for some tang.
Can I use a slow cooker for this recipe?
Yes, you can use a slow cooker! Start by browning the beef first for flavor. Then, combine the sauce ingredients in the slow cooker. Cook on low for 4-5 hours or high for 2-3 hours. This method makes the beef very tender. Just remember to add the green onions near the end for freshness!
