Mongolian Beef
Mongolian Beef is a classic dish that’s incredibly satisfying to make and even more delightful to eat.

While it sounds exotic, the ingredients are readily available at most grocery stores, and the process is straightforward, making it a fantastic weeknight meal. Get ready to impress yourself and your loved ones with this restaurant-quality dish!
Ingredients:
Preparing the Beef
The key to tender Mongolian Beef is the marination. We’ll start by preparing the beef. Ensure your beef is thinly sliced. If your butcher can do it, even better! If not, partially freezing the flank steak for about 30-45 minutes makes it much easier to slice thinly.
In a medium bowl, combine the thinly sliced beef with 2 tablespoons of water, 2 teaspoons of Shaoxing rice vinegar, ½ teaspoon of Kosher salt, and ¼ teaspoon of baking soda. The baking soda is a secret weapon here; it helps to tenderize the beef by raising its pH level, allowing it to retain moisture during the cooking process. Gently mix everything together, ensuring each slice of beef is coated. Let this mixture marinate for at least 15 minutes at room temperature.
After the marination, drain off any excess liquid. Add 2 tablespoons of cornstarch to the marinated beef and toss well until every piece is lightly coated. The cornstarch will help create a slightly crispy exterior when fried and will also thicken our sauce later. Set the beef aside.
Crafting the Sauce
While the beef is marinating, let’s prepare the sauce that will bring all the flavors together. In a small bowl, whisk together 1 tablespoon of Shaoxing rice vinegar, 3 tablespoons of granulated sugar, and 2 tablespoons of regular soy sauce. Stir until the sugar is mostly dissolved. This is the foundation of our savory and slightly sweet sauce. Set this sauce aside.
The Stir-Fry Process
Now for the exciting part – cooking! We’ll be doing this in stages to ensure everything is cooked perfectly.
1. Sear the Beef: Heat 1 tablespoon of neutral oil in a large wok or a deep skillet over high heat until it’s shimmering. Carefully add the cornstarch-coated beef in a single layer. You might need to do this in batches to avoid overcrowding the pan, which can lead to steaming instead of searing. Cook for about 1-2 minutes per side, just until it’s browned and slightly crisped. Don’t overcook it at this stage, as it will cook more when combined with the sauce. Remove the seared beef from the wok and set it aside on a plate.
2. Sauté Aromatics and Vegetables: Add the minced garlic and cracked black pepper to the same wok (add a tiny bit more oil if the pan seems dry). Stir-fry for about 30 seconds until fragrant, being careful not to burn the garlic. Add the sliced yellow onion and the white parts of the green onions. Stir-fry for another 1-2 minutes until the onions begin extract to soften and become slightly translucent.
3. Combine and Sauce: Return the seared beef to the wok with the softened onions and garlic. Give the prepared sauce mixture a quick stir and pour it over the beef and vegetables. Stir everything to coat evenly.
4. Thicken the Sauce: Continue to stir-fry over high heat. The sauce will start to bubble and thicken as the cornstarch from the beef coating and the heat work together. This should only take about 1-2 minutes. Once the sauce has thickened to your desired consistency, add the green parts of the green onions and toss to combine.
5. Optional Noodle Addition: If you are using rice vermicelli, this is the time to incorporate them. If your vermicelli is pre-cooked and softened (as per package directions), add them to the wok and toss them gently with the beef and sauce until heated through. If using uncooked vermicelli that will cook in the sauce, you might need to add a tablespoon or two of water to ensure they cook through, but be careful not to make the sauce too thin. Toss everything together until the vermicelli is coated and tender.
Serve your delicious Mongolian Beef immediately over steamed rice or with your favorite noodles. The combination of tender beef, savory-sweet sauce, and crisp-tender vegetables is truly irresistible. Enjoy the fruits of your labor!

Frequently Asked Questions:
Can I make the sauce ahead of time?
Absolutely! The sauce for Mongolian Beef can be prepared a day or two in advance and stored in an airtight container in the refrigerator. This makes assembly even quicker when you’re ready to cook. Just give it a good whisk before adding it to the stir-fry.
What’s the best way to get the beef tender?
For the most tender beef, slice it thinly against the grain. Marinating the beef, even for a short period, also helps to break down the fibers and ensure a succulent texture. Using a cornstarch slurry in the marinade is a common and effective technique.
Can I add other vegetables to this Mongolian Beef?
Yes, feel free to customize! Bell peppers (any color), onions, carrots, broccoli florets, and snap peas are all excellent additions that complement the flavors beautifully.
