Step‑by‑Step Instructions for Crispy Mongolian Beef
Step 1: Prep the Beef
Begin by slicing the flank steak into thin, bite-sized pieces. In a mixing bowl, toss the beef with cornstarch, kosher salt, and black pepper until well-coated—this will create that irresistible crunch when fried. Let the beef sit for about 10 minutes to absorb the flavors while you prepare the sauce.
Step 2: Make the Sauce
In a saucepan over medium heat, combine the low-sodium soy sauce, chicken broth, dark brown sugar, and half of the fresh ginger and garlic. Stir the mixture gently, allowing it to come to a simmer. Cook for about 15 minutes, or until slightly thickened and fragrant, then set aside. This sticky glaze will enhance your Crispy Mongolian Beef beautifully.
Step 3: Fry the Beef
Heat about 1 inch of vegetable oil in a wok or large skillet over medium-high heat until shimmering (approximately 375°F). Carefully add the coated beef in batches, ensuring not to overcrowd the pan. Fry until golden and crispy, about 1-2 minutes per side. Once cooked, transfer the beef onto paper towels to drain excess oil, keeping it warm while you finish the dish.
Step 4: Finish the Sauce
Remove excess oil from the wok, leaving a little for flavor. Add the remaining garlic and ginger to the pan, sautéing until fragrant, about 2 minutes. Then, pour in the pre-prepared sauce and bring it to a gentle boil. Let it reduce for about 5 minutes until it becomes thick and sticky, perfect for coating the crispy beef.
Step 5: Combine
Once the sauce has thickened, add the crispy beef to the wok, tossing gently to coat the pieces evenly with the delicious glaze. Cook for an additional minute, ensuring every piece of beef is nicely covered in the sauce. This step is crucial to achieving that delightful flavor combination in your Crispy Mongolian Beef.
Step 6: Serve
Remove the wok from heat and transfer your Crispy Mongolian Beef to a serving platter. Garnish with sliced green onions and sprinkle with sesame seeds for extra flair. Serve immediately over fluffy white rice or alongside steamed vegetables for a complete and satisfying meal. Enjoy this quick dish with your loved ones!

Storage Tips for Crispy Mongolian Beef
-
Fridge: Store leftover Crispy Mongolian Beef in an airtight container for up to 3 days. This will help retain the flavors and ensure it stays delicious for your next meal.
-
Freezer: If you need to keep it longer, freeze the beef in an airtight container for up to 2 months. To maintain texture, believe it or not, it’s best to freeze without the sauce.
-
Reheating: When ready to enjoy, reheat by placing it in an oven or air fryer at 375°F for about 10-15 minutes to revive the crispy texture. Avoid the microwave, as it may lead to a soggy result.
-
Thawing: For frozen leftovers, thaw in the fridge overnight before reheating. This will help ensure even warming and keep your Crispy Mongolian Beef in top shape!
Expert Tips for Crispy Mongolian Beef
- Beef Preparation: Chill the flank steak in the freezer for about 10 minutes before slicing. This makes it easier to cut thin, even pieces for perfect frying.
- Cornstarch Coating: Ensure the beef is evenly coated with cornstarch. Too little won’t give you the crunchy texture, while excess can create a gummy layer.
- Frying Method: Avoid overcrowding the pan when frying. Cook in batches to ensure each piece gets crispy and golden without steaming.
- Sauce Consistency: Simmer your sauce long enough to get that thick, sticky consistency, which is essential for coating your Crispy Mongolian Beef beautifully.
- Serving Fresh: Serve immediately after tossing the beef in sauce for maximum crispiness. If reheating leftovers, do so in an oven or air fryer instead of a microwave to preserve texture.

Crispy Mongolian Beef Recipe FAQs
What type of flank steak should I use for this recipe?
Absolutely! Look for fresh flank steak that is bright red with minimal dark spots. The meat should be firm to the touch, and I recommend choosing grass-fed or organic if possible for enhanced flavor.
How should I store leftover Crispy Mongolian Beef?
Simply place leftovers in an airtight container in the refrigerator, where they can stay fresh for up to 3 days. To keep the beef juicy and flavorful, ensure it’s sealed tightly.
Can I freeze Crispy Mongolian Beef? How?
Very! To freeze, first, allow the beef to cool completely after cooking. Place it in a freezer-safe container or bag, leaving some space for expansion, and store for up to 2 months. To maintain its crispy texture, I suggest freezing the beef without the sauce; you can prepare the sauce fresh after thawing.
What should I do if the beef isn’t crispy after frying?
Not to worry! If you find the beef isn’t getting crispy, check your oil temperature—it should be around 375°F when frying. The oil needs to be hot enough to create that golden crust; if it’s too cool, the beef may steam instead. Also, ensuring not to overcrowd the pan will help each piece fry evenly and become deliciously crispy!
Is this recipe suitable for a gluten-free diet?
Absolutely! To make your Crispy Mongolian Beef gluten-free, substitute soy sauce with tamari or a gluten-free soy sauce alternative. For the broth, ensure you use a gluten-free version as well. Adjust the spice level using gluten-free sambal oelek or Sriracha. Enjoy without worry!
