Step 1: Prepare the Flank Steak
Start by thinly slicing the flank steak against the grain. This step is crucial for ensuring tenderness. Aim for slices about 1/4 inch thick. Once sliced, place the beef in a large bowl and toss it with cornstarch until fully coated. Allow it to rest while you prepare the sauce.
Step 2: Make the Sauce
In a medium bowl, whisk together the soy sauce, dark brown sugar, water, garlic, and minced ginger. Make sure everything is well combined, and set aside.
Step 3: Heat the Oil
In a large skillet or wok, heat the vegetable oil over medium-high heat. You want the oil to be hot enough that it shimmers but not smoking. This is crucial for achieving that perfect crispy texture on the beef.
Step 4: Cook the Beef
Once the oil is hot, carefully add the coated flank steak in batches. Avoid overcrowding the pan to ensure even cooking. Fry the beef for 2-3 minutes on each side until it’s golden brown and crisp. Remove the beef from the skillet and place it on a paper towel-lined plate to drain excess oil.
Step 5: Combine Everything
In the same skillet, drain any excess oil, leaving about 1 tablespoon. Pour in the prepared sauce and bring it to a simmer. Allow it to cook for 2-3 minutes until it thickens slightly. Return the cooked beef to the skillet, tossing to coat it in the sauce.
Step 6: Finish with Green Onions
Add the sliced green onions to the skillet, stirring them in to soften slightly. Cook for an additional minute, and then drizzle with sesame oil for added flavor.
Step 7: Serve
Transfer the Mongolian beef to a serving dish and sprinkle with sesame seeds for garnish. Serve hot over steamed rice or noodles for a complete meal.
Seasonal Adaptations

- Spring: Add snap peas or asparagus for a fresh crunch.
- Summer: Toss in bell peppers for a pop of color and sweetness.
- Fall: Incorporate roasted butternut squash for a seasonal twist.
- Winter: Pair with broccoli or bok choy for added nutrients.
Slip-Ups to Skip
- Do not skip coating the beef in cornstarch; it’s essential for that crispy exterior.
- Ensure your oil is hot enough before adding the beef; this prevents steaming instead of frying.
- Avoid overcrowding the skillet; cook in batches if necessary for even browning.
- Don’t skip the garlic and ginger; they are key to the dish’s flavor.
Store, Freeze & Reheat
Leftover Mongolian beef can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze the cooked beef in a freezer-safe container for up to 3 months. To reheat, thaw in the refrigerator overnight and warm gently in a skillet over low heat or microwave until heated through. Note that the crispy texture may soften during storage.
