Prep & Cook Tools
Before you start cooking, make sure you have the following tools ready:
- Chef’s knife: For slicing the flank steak and green onions.
- Cutting board: A stable surface for your chopping needs.

Mongolian Beef Recipe Made Stepwise

Step 1: Prepare the Flank Steak
Start by slicing the flank steak thinly across the grain. This ensures that the meat will be tender once cooked. Place the sliced beef in a mixing bowl and sprinkle the cornstarch over it. Toss the beef until it is evenly coated with cornstarch. This step is crucial as it helps create a crispy crust when frying.
Step 2: 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 to fry the beef, so give it a few minutes.
Step 3: Cook the Beef
Once the oil is hot, carefully add the cornstarch-coated beef to the skillet in a single layer. Avoid overcrowding the pan; you may need to cook the beef in batches. Fry the beef for about 2-3 minutes on each side until it is golden brown. Remove the cooked beef from the skillet and place it on a plate lined with paper towels to drain any excess oil.
Step 4: Prepare the Sauce
In the same skillet, add the minced garlic and ginger. Stir-fry for about 30 seconds until fragrant. Then, pour in the soy sauce, dark brown sugar, and water. Stir the mixture until the sugar is dissolved and the sauce is well combined.
Step 5: Combine Beef and Sauce
Return the cooked beef to the skillet and toss it in the sauce, ensuring that every piece is well coated. Cook for an additional 2-3 minutes, allowing the sauce to thicken slightly.
Step 6: Add Green Onions & Serve
Finally, add the sliced green onions and drizzle the sesame oil over the beef. Stir everything together and cook for an extra minute. Remove from heat, sprinkle with sesame seeds, and serve hot over rice or noodles.
How to Make It Lighter

If you’re looking to lighten up this Mongolian Beef recipe, consider the following tips:
- Replace some of the vegetable oil with a non-stick cooking spray to reduce fat content.
- Use leaner cuts of beef, such as sirloin or tenderloin, instead of flank steak.
- Reduce the amount of brown sugar in the sauce or substitute with a natural sweetener.
- Serve over steamed vegetables instead of rice for a low-carb option.
Troubleshooting Tips
Here are some common issues and solutions to make your Mongolian Beef perfect:
- Beef is tough: Ensure you’re slicing against the grain and not overcooking the beef.
- Sauce is too thick: Add a little water to the sauce while cooking to thin it out.
- Sauce is too sweet: Add a splash more soy sauce to balance the sweetness.
- Beef is greasy: Make sure to drain the cooked beef on paper towels before adding it to the sauce.
Prep Ahead & Store
This Mongolian Beef can be prepped ahead of time for convenience. Here are some storage tips:
- Slice the beef and mix it with cornstarch a few hours ahead of cooking and refrigerate.
- The sauce can be made in advance and stored in the refrigerator for up to a week.
- Cooked Mongolian Beef can be stored in an airtight container in the fridge for up to 3 days.
- Reheat the beef in a skillet over medium heat, adding a splash of water to revive the sauce.
