Recommended Products for This Recipe
These are a few products I personally use and love when making Mongolian Beef at home. They make a real difference in the final result.
1. Carbon Steel Wok
A good carbon steel wok heats up fast and gets hot enough to give your beef that restaurant-style sear.
It distributes heat more evenly than most skillets, and the slightly sloped sides make tossing and stirring a breeze.
Once seasoned, it’s naturally non-stick and practically indestructible.
2. Premium Low-Sodium Soy Sauce
The soy sauce you use makes a huge impact on the overall flavor of this dish.
A good quality low-sodium soy sauce gives you rich, savory depth without making the sauce overwhelmingly salty.
It also gives you more control over the seasoning as you cook.
3. Toasted Sesame Oil
A small drizzle of toasted sesame oil at the end of cooking adds a nutty, aromatic finish that takes the whole dish from good to amazing.
Look for one that’s 100% pure toasted sesame oil, the flavor difference is noticeable.
4. Microplane Zester and Grater
Freshly grated ginger is so much more vibrant than the jarred stuff, and a Microplane makes it effortless.
The fine grating surface ensures the ginger blends seamlessly into the sauce without any fibrous chunks.
Step-by-Step Instructions: How to Make Mongolian Beef
1. Slice and Prep the Beef
- Place the flank steak in the freezer for 15–20 minutes before slicing. This firms it up slightly and makes it much easier to cut thin, even slices.
- Once chilled, place the steak on your cutting board and identify the direction of the grain (the lines running through the meat).
- Using a sharp chef’s knife, slice the beef against the grain into strips about ¼ inch thick. Cutting against the grain breaks up the muscle fibers and results in tender, easy-to-chew pieces.
- Pat the sliced beef completely dry with paper towels. This step is crucial, any moisture on the surface will cause the beef to steam instead of sear, and you’ll miss out on that golden-brown crust.
2. Coat the Beef in Cornstarch
- Place the dried beef slices into a large mixing bowl.
- Add â…“ cup of cornstarch over the beef.
- Toss well until every piece is thoroughly coated. The cornstarch creates a light, crispy coating that also helps the sauce cling to the beef beautifully. Don’t skip this step.
- Set the coated beef aside and let it sit for 5 minutes while you prepare the sauce. During this time, the cornstarch will slightly absorb into the surface of the meat.
3. Make the Mongolian Beef Sauce
- In a small bowl or measuring cup, combine ½ cup low-sodium soy sauce, ½ cup water, and ½ cup packed brown sugar.
- Stir until the brown sugar is mostly dissolved. The mixture should look like a thin, dark, slightly sweet sauce at this stage.
- Add 1 teaspoon of sesame oil and ½ teaspoon of red pepper flakes if using. Stir to combine.
- Set the sauce aside, it goes into the pan after the beef and aromatics are ready.
4. Sear the Beef
- Heat a large wok or skillet over high heat. Let the pan get very hot before adding any oil, this takes about 1–2 minutes. A hot pan is key to getting a proper sear.
- Add 2 tablespoons of vegetable oil to the pan and swirl to coat.
- Working in batches (don’t crowd the pan), add the cornstarch-coated beef slices in a single layer.
- Let the beef cook undisturbed for 1–2 minutes until the bottom is browned and slightly crispy. Resist the urge to stir, you want a sear, not a steam.
- Flip each piece and cook for another 30–60 seconds on the other side.
- Transfer the seared beef to a plate and repeat with the remaining beef, adding a little more oil if needed between batches.
5. Sauté the Aromatics
- Reduce the heat to medium and add the remaining 1 tablespoon of vegetable oil to the same pan.
- Add the 5 minced garlic cloves and 1 teaspoon of freshly grated ginger to the pan.
- Stir constantly and cook for about 30–45 seconds, just until fragrant. Be careful not to burn the garlic, it can go from golden to bitter very quickly at this heat level.
6. Add the Sauce and Simmer
- Pour the prepared soy sauce mixture into the pan with the garlic and ginger.
- Stir everything together and bring the sauce to a simmer over medium heat.
- Let the sauce cook for 3–4 minutes, stirring occasionally. It will reduce slightly and start to thicken as the sugars concentrate. You’ll know it’s ready when it coats the back of a spoon.
7. Combine Beef and Sauce
- Return all the seared beef back to the pan with the sauce.
- Add the sliced green onions (reserving a small handful for garnish).
- Toss everything together so the beef is evenly coated in the glossy sauce. Cook for another 1–2 minutes until everything is heated through and the sauce has clung to every piece of beef.
8. Plate and Serve
- Spoon the Mongolian Beef over a bed of steamed white rice or noodles.
- Garnish with the reserved green onions and a sprinkle of sesame seeds if desired.
- Serve immediately while the sauce is glossy and the beef is hot. Mongolian Beef is best enjoyed right off the stove.
This dish also pairs wonderfully with my homemade teriyaki sauce if you want to drizzle a little extra flavor on the side.
Tips for The Best Mongolian Beef
A few simple tricks separate a good Mongolian Beef from a truly great one. The most important? Don’t rush the sear and don’t skip the cornstarch coating.
- Freeze the beef briefly before slicing. Even 15 minutes in the freezer makes the steak firmer and dramatically easier to cut into thin, uniform slices.
- Always cut against the grain. This is non-negotiable for tender beef. Cutting with the grain leaves you with chewy, stringy pieces.
- Pat the beef completely dry. Moisture is the enemy of a good sear. Use paper towels and press firmly to remove as much surface moisture as possible.
- Don’t overcrowd the pan. Sear the beef in batches if needed. Too many pieces at once drops the pan temperature and steams the beef instead of browning it.
- Use high heat for the sear. Mongolian Beef is a high-heat, fast-cooking dish. A screaming hot wok is your best friend here.
- Taste and adjust the sauce. Before adding the beef back in, taste the sauce. Want it sweeter? Add a little more brown sugar. Want more savory depth? A splash more soy sauce does it.
- Don’t overcook the beef. The slices are thin and cook fast. Once they’re browned and the sauce is coating them, it’s time to plate.

Serving Suggestions
Mongolian Beef is incredibly satisfying on its own, but paired with the right sides, it becomes a full restaurant-quality meal at home.
Steamed jasmine rice is the classic and most popular pairing, the fluffy grains soak up all that glossy sauce beautifully.
If you want something heartier, lo mein noodles or even udon work wonderfully.
- Steamed jasmine or white rice: The go-to classic. Let the rice absorb every drop of that savory-sweet sauce.
- Lo mein or udon noodles: Toss the noodles right into the pan with the beef and sauce for a noodle bowl variation.
- Steamed or stir-fried broccoli: The slightly bitter, vegetal flavor of broccoli balances the richness of the sauce perfectly.
- Fried rice: Serve Mongolian Beef on top of fried rice for an extra satisfying combo that uses up leftover rice.
- Crispy spring rolls or One Pan Dumpling Bake: Great as a starter or served alongside for a fuller spread.
- Simple cucumber salad: A light, acidic cucumber salad helps cut through the richness of the beef and sauce.
- Steamed bok choy: A quick steam with a drizzle of sesame oil and garlic makes a beautiful, simple side.
Variations of Mongolian Beef
Once you’ve nailed the base recipe, it’s easy and fun to put your own spin on it. These are some of the most popular variations that keep things fresh and interesting.
- Mongolian Beef with Broccoli: Add a cup of blanched or stir-fried broccoli florets during the final step. It adds color, nutrition, and a satisfying crunch to the dish.
- Spicy Mongolian Beef: Double the red pepper flakes or add a tablespoon of chili garlic sauce to the sauce mixture for a bolder, spicier version.
- Mongolian Chicken: Swap the flank steak for thinly sliced chicken thighs or breast. The sauce and technique remain exactly the same.
- Slow Cooker Mongolian Beef: Skip the sear and toss everything in the slow cooker on low for 4–5 hours. The texture is different but the flavor is equally delicious. Check out this Crockpot Pepper Steak for a similar slow cooker beef approach.
- Vegetarian Mongolian “Beef”: Use extra-firm tofu or seitan in place of the beef. Press and slice the tofu, coat in cornstarch, and follow the exact same steps for a plant-based version.
- Mongolian Beef Noodle Bowl: Instead of serving over rice, toss cooked ramen or lo mein noodles directly into the pan with the sauce and beef to create a hearty noodle bowl.
- Low-Sugar Version: Reduce the brown sugar to ¼ cup and add a teaspoon of honey instead. The flavor profile stays balanced with a slightly less sweet, deeper note.

Storage and Reheating
Mongolian Beef stores well and makes excellent leftovers, if anything, the flavors deepen overnight as the beef continues to soak in the sauce.
- Refrigerator: Store leftovers in an airtight container in the fridge for up to 3–4 days.
- Freezer: You can freeze Mongolian Beef for up to 2 months. Let it cool completely before transferring to a freezer-safe container or zip-lock bag. Freeze flat for easy stacking.
- Reheating on the stovetop (best method): Add a splash of water or extra soy sauce to the pan, then reheat over medium heat for 3–5 minutes, tossing occasionally until warmed through. This brings the sauce back to life.
- Reheating in the microwave: Transfer to a microwave-safe bowl, cover loosely, and heat in 60-second intervals, stirring between each, until hot. Add a small splash of water if the sauce looks dry.
- Reheating from frozen: Thaw in the refrigerator overnight, then reheat using either stovetop or microwave methods above.
- Do not reheat more than once: For the best texture and food safety, only reheat what you plan to eat.

Health Benefits of Key Ingredients
While Mongolian Beef is definitely a treat, several of the key ingredients actually bring some real nutritional value to the table.
Flank steak is one of the leaner cuts of beef available, and it’s loaded with protein and essential minerals like iron, zinc, and B12, all critical for energy, immunity, and muscle repair.
- Flank Steak: High-quality protein that supports muscle maintenance and repair, plus iron for healthy red blood cells and sustained energy levels throughout the day.
- Garlic: Known for its anti-inflammatory and immune-boosting properties, garlic contains allicin, which has been shown to support cardiovascular health and help fight off infections.
- Fresh Ginger: Ginger is a powerful anti-inflammatory and antioxidant. It supports digestion, can help reduce nausea, and adds a bright, warming quality to the dish that goes far beyond just flavor.
- Sesame Oil: Rich in healthy unsaturated fats and antioxidants like sesamol, sesame oil supports heart health and adds a deeply nutty flavor with just a small amount.
- Low-Sodium Soy Sauce: Compared to regular soy sauce, the low-sodium version provides the same umami depth while significantly reducing sodium intake, making it a smarter choice for those monitoring blood pressure.
- Green Onions: These mild alliums are a surprisingly good source of vitamins K and C, both important for bone health, skin, and immune function.
This recipe also pairs beautifully with a side of steamed vegetables, which further boosts the nutritional profile of the meal.

FAQs About Mongolian Beef
1. What cut of beef is best for Mongolian Beef?
Flank steak is the most commonly used cut for Mongolian Beef, and for good reason. It’s lean, flavorful, and slices beautifully thin when cut against the grain.
Skirt steak is a close second if flank steak isn’t available. Sirloin or ribeye can also work, though they’re richer and slightly different in texture.
2. Why is my beef tough and chewy instead of tender?
The most common culprit is cutting the beef with the grain instead of against it. Always look for the lines running through the meat and slice perpendicular to them.
Overcooking is another common cause, thin beef slices cook very quickly, so once they’re browned, they should come out of the pan right away.
3. Can I make Mongolian Beef ahead of time?
Yes! You can slice the beef and prepare the sauce up to a day in advance, storing each separately in the fridge.
When you’re ready to eat, just sear the beef and finish the sauce, it all comes together in under 15 minutes.
You can also store fully cooked leftovers for up to 4 days in the refrigerator. The flavor actually improves as the beef soaks in the sauce overnight.
4. Is Mongolian Beef actually from Mongolia?
Despite the name, Mongolian Beef as we know it is a Chinese-American creation, not a traditional Mongolian dish.
It was popularized in Chinese-American restaurants, particularly those influenced by Taiwanese-American cuisine, and bears little resemblance to actual Mongolian cooking traditions.
The name is thought to refer to a Mongolian barbecue cooking style (teppanyaki-inspired cooking over high heat) rather than the cuisine of Mongolia itself.
5. Can I make this dish gluten-free?
Absolutely. The main swap is replacing regular soy sauce with tamari or a certified gluten-free soy sauce, the flavor is essentially identical.
Just double-check that your cornstarch is also labeled gluten-free, as some brands are processed in facilities that handle wheat.
Everything else in the recipe is naturally gluten-free, so with those two simple swaps, you’re good to go.

Nutrition
Notes
- Freeze before slicing: Chilling the flank steak for 15–20 minutes makes it much easier to cut thin, even slices — don’t skip this step.
- Always cut against the grain: Slicing perpendicular to the muscle fibers is the key to tender (not chewy) beef.
- Pat the beef dry: Removing surface moisture ensures a proper sear rather than steaming the meat.
- Don’t crowd the pan: Sear beef in batches if needed — overcrowding drops the pan temperature and prevents browning.
- Adjust sweetness: Start with ½ cup brown sugar and adjust to taste. Reduce to ¼ cup for a less sweet, more savory sauce.
- Make it spicy: Double the red pepper flakes or add 1 tablespoon of chili garlic sauce for extra heat.
- Add vegetables: Stir in blanched broccoli, snap peas, or bell peppers during the final toss for a more complete one-pan meal.
