Step‑by‑Step Instructions for Crispy Mongolian Beef
Step 1: Prepare the Beef
Begin by slicing the flank steak against the grain into thin strips, approximately ¼ inch thick for the best tenderness. Aim for uniform pieces to ensure even cooking. Set the sliced steak aside while you prepare the cornstarch coating, allowing the juices to marinate slightly.
Step 2: Coat the Steak
In a mixing bowl, liberally coat the steak strips with cornstarch, ensuring each piece is thoroughly covered for that crispy texture. Let the coated beef rest for about 5 minutes, allowing the cornstarch to adhere better. This step is crucial for achieving the perfectly crispy crust that defines your Crispy Mongolian Beef.
Step 3: Heat the Oil
In a large skillet, heat 2 tablespoons of vegetable oil over medium-high heat, reaching about 350°F (175°C). You can test if the oil is ready by adding a small pinch of cornstarch; it should sizzle immediately upon contact. This high heat will create a beautiful, golden-brown crust on the beef when fried.
Step 4: Fry the Beef
Carefully add the coated steak strips to the hot oil in a single layer, avoiding overcrowding the pan. Fry for about 3-4 minutes per side, or until the beef is crispy and browned. Keep an eye on the color; you want a nice golden texture to develop, giving your Crispy Mongolian Beef that appetizing look and crunch.
Step 5: Mix the Sauce
While the beef is frying, combine ¼ cup soy sauce, ¼ cup brown sugar, minced garlic, and grated ginger in a separate bowl. Stir well until the sugar is dissolved completely. This sauce will add that mouthwatering sweetness and rich flavor to your dish, balancing out the crispy beef beautifully.
Step 6: Combine and Stir
Once the beef strips are fried to perfection, carefully pour the sauce mixture over the beef in the skillet. Reduce the heat to medium and stir gently for about 1-2 minutes, allowing the sauce to coat the beef evenly and caramelize slightly. Watch for the sauce to thicken just a bit, enhancing the joy of your Crispy Mongolian Beef.
Step 7: Garnish and Serve
Remove the skillet from the heat and transfer the Crispy Mongolian Beef to a serving dish. Garnish with sliced green onions and, if desired, a sprinkle of sesame seeds to add a touch of elegance and crunch. Serve hot and enjoy this delightful dish with rice or noodles for a complete meal experience!

Expert Tips for Crispy Mongolian Beef
• Proper Slicing: Slice the flank steak against the grain to maximize tenderness. This simple trick makes a world of difference in your Crispy Mongolian Beef!
• Cornstarch Coverage: Ensure even coating of cornstarch on the beef. Let it rest for a few minutes; this helps achieve that irresistible crunch when frying.
• Hot Oil: Make sure your oil is hot enough (about 350°F) before adding the beef. If the oil isn’t hot, the meat will absorb it and lose its crispiness.
• Avoid Overcrowding: Fry the steak in batches if necessary. Overcrowding the pan lowers the oil temperature, resulting in soggy instead of crispy beef.
• Sauce Timing: Pour the sauce over the beef while it's still hot. This allows the flavors to meld beautifully and caramelizes nicely, enhancing the taste of your dish!
• Garnishing: Don't skip on garnishes! Scallions and optional sesame seeds not only add flavor but also a pop of color that makes your Crispy Mongolian Beef visually appealing.
How to Store and Freeze Crispy Mongolian Beef
Fridge: Store leftovers in an airtight container for up to 3 days. This helps maintain the flavors while keeping the meat fresh.
Freezer: For longer storage, freeze the Crispy Mongolian Beef in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating: To maintain the crispy texture, reheat in a skillet over medium heat, stirring occasionally for about 5-7 minutes, until heated through. Avoid microwaving, as it may make the beef soggy.
Serving: Once reheated, garnish again with green onions and sesame seeds to refresh the dish and restore its appetizing appeal!
Make Ahead Options
These Crispy Mongolian Beef strips are perfect for meal prep enthusiasts! You can coat and refrigerate the steak strips in cornstarch up to 24 hours in advance, which helps them stay crunchy when cooked. Additionally, mix the sauce (soy sauce, brown sugar, garlic, and ginger) and store it in an airtight container in the fridge for up to 3 days. When you're ready to serve, simply fry the coated beef for about 3-4 minutes per side until crispy, then add the sauce and stir for 1-2 minutes until well combined. This way, you’ll have a delicious, homemade meal with minimal effort, just as satisfying as takeout!
