- 1 teaspoon sesame oil – Brings a nutty, earthy flavor to the dish.
- ½ teaspoon red pepper flakes (optional) – For a little heat, but you can adjust this based on your spice preference.

Step-by-Step Instructions for Making Mongolian Beef
Step 1: Prepare the Beef
The first step in making Mongolian Beef is preparing the beef. Start by slicing the flank steak thinly against the grain. This will ensure that the beef remains tender and easy to chew. Next, toss the beef slices with cornstarch, making sure each piece is evenly coated. Let the beef sit for about 10 minutes. The cornstarch helps create that crispy texture when the beef is fried in the oil.
Step 2: Cook the Beef
In a large skillet or wok, heat the vegetable oil over medium-high heat. Once the oil is hot, add the beef in batches, ensuring that each piece is seared and crispy. Cook the beef for 2-3 minutes on each side, until golden brown. Once done, remove the beef from the skillet and set it aside.
Step 3: Make the Sauce
In the same skillet, lower the heat to medium and add the minced garlic and grated ginger. Sauté for about 30 seconds, or until fragrant. This will release the flavors and create the base for your sauce. Next, pour in the soy sauce, water, and brown sugar, stirring well to combine. Allow the sauce to simmer for 2 minutes to thicken slightly.
Step 4: Combine Everything
Return the cooked beef to the skillet, making sure to coat each piece thoroughly with the sauce. Add the sesame oil, red pepper flakes (if using), and sliced green onions. Stir everything together for another 2 minutes, allowing the beef to absorb the flavors of the sauce.
Step 5: Serve and Enjoy
Once the Mongolian Beef is ready, transfer it to a serving dish and garnish with sesame seeds. You can serve this dish with steamed rice or noodles, and it pairs beautifully with stir-fried vegetables or a side salad for a complete meal.
Tips for Making the Perfect Mongolian Beef
- Slice the Beef Thinly: The key to making Mongolian Beef tender and juicy is slicing the beef thinly against the grain. This will help ensure that the beef cooks quickly and evenly.
- Use Low-Sodium Soy Sauce: If you’re watching your sodium intake, using low-sodium soy sauce helps control the saltiness of the dish without compromising the flavor.
- Adjust the Spice: If you like your Mongolian Beef on the spicier side, feel free to add more red pepper flakes or even some chili paste to the sauce.
- Customize the Vegetables: You can add other vegetables to the dish, such as bell peppers, broccoli, or carrots. Stir-fry them alongside the beef to add more texture and color.
- Make It Gluten-Free: To make the dish gluten-free, swap out the soy sauce for tamari and check that the cornstarch you’re using is certified gluten-free.
