Step-by-Step Instructions
Marinating the Beef
To start, take your flank steak and slice it thinly. This helps it cook fast and stay tender. Place the sliced beef into a medium bowl. Now, add the cornstarch. Toss the beef well until it is fully coated. This step makes the beef crispy when cooked. Let the beef rest for about 15 minutes. This resting time helps the cornstarch work its magic.
Preparing the Sauce
While the beef marinates, grab a small bowl. Whisk together the soy sauce, brown sugar, minced garlic, grated ginger, and red pepper flakes. Mix until the sugar dissolves. This sauce is where a lot of flavor comes from. Set this sauce aside for later use.
Cooking the Beef
Next, heat 2 tablespoons of vegetable oil in a large skillet or wok over medium-high heat. Once the oil shimmers, it is ready. Add the marinated beef in a single layer. You might need to cook in batches to avoid overcrowding. Sear the beef for about 2-3 minutes until it turns brown. This browning adds depth to the flavor. Once done, remove the beef from the pan and set it aside.
Final Steps
In the same skillet, add the remaining tablespoon of vegetable oil. Toss in the white parts of the green onions and sauté for about 1 minute until fragrant. This step brings out the onion’s flavor. Now, pour in the sauce and let it simmer for 2-3 minutes. This helps the sauce thicken slightly. Return the beef to the skillet and toss everything together. Drizzle with sesame oil and cook for another minute. Finally, fold in the green parts of the green onions for a nice crunch. Enjoy your Mongolian beef over jasmine rice!
Tips & Tricks
Perfecting the Marinade
Marinating beef is key. It helps tenderize the meat and adds great flavor. I suggest marinating flank steak for at least 15 minutes. This short time works well with cornstarch, which gives the beef a nice texture. When choosing flank steak, look for bright color and a good amount of fat. Fat gives the meat flavor and keeps it juicy.
Cooking Techniques
The right skillet temperature is very important. Heat your skillet over medium-high heat. This allows the beef to sear well and develop a nice crust. Don’t crowd the pan. Cook the beef in batches if needed. This way, every slice gets that perfect sear.
Enhancing Flavor
Want to adjust the spice level? You can add more or less red pepper flakes to your taste. If you prefer a sweeter sauce, add a bit more brown sugar. To switch things up, try adding hoisin sauce or oyster sauce for a unique twist. These sauces can bring new depth to your dish.
Pro Tips
- Use a Sharp Knife: A sharp knife makes it easier to slice the flank steak thinly, ensuring even cooking and a tender bite.
- Marinate for Flavor: Allowing the beef to marinate in cornstarch not only tenderizes it but also helps the sauce cling better during cooking.
- Sear in Batches: Avoid overcrowding the pan when searing the beef. Cooking in batches helps achieve that nice brown crust without steaming the meat.
- Adjust Spice Level: Feel free to modify the amount of red pepper flakes according to your heat preference for a personalized touch.
Variations
Protein Substitutions
You can change the meat in this dish. Chicken or tofu works great. For chicken, use thin slices of chicken breast. For tofu, use firm tofu and press it to remove water. Both options soak up the flavors well. You can also try other beef cuts, like sirloin or ribeye. These cuts are tasty too but may need slight adjustments in cooking time.
Vegetable Additions
Adding vegetables makes your Mongolian beef more colorful and healthy. Bell peppers add a sweet crunch. Just slice them thin and add them when you sauté the green onions. Broccoli is another great choice. It adds a nice texture and flavor. You can also try a mixed vegetable stir-fry. Use carrots, snow peas, or baby corn for a fun twist.
Dietary Modifications
If you need gluten-free options, use tamari instead of soy sauce. It tastes similar but is gluten-free. For a low-carb version, skip the brown sugar or use a sugar substitute. You can also serve the beef over cauliflower rice instead of jasmine rice. These changes keep the dish tasty while meeting your dietary needs.
Storage Info
Refrigerating Leftovers
Store your Mongolian beef in proper airtight containers. Glass or plastic containers work well. Keep the beef in the fridge for up to 3 days. After that, it may lose its great taste and texture.
Reheating Instructions
To reheat, use a skillet over low heat. This method helps keep the beef tender. Stir often and add a splash of water or broth if needed. You can also microwave the beef in short bursts, checking to avoid overcooking.
Freezing for Future Meals
If you want to freeze Mongolian beef, first let it cool. Use freezer-safe bags or containers to save space. Squeeze out air to prevent freezer burn. It can last up to 3 months in the freezer. When ready to eat, thaw in the fridge overnight. Reheat using the skillet method for the best flavor.
