Soups & Stews
This Andy Cooks Mongolian Beef recipe delivers restaurant-quality tenderness with that signature wok hei smoke and sweet soy glaze. The secret lies in marinating thinly sliced beef for at least 30 minutes—allowing the sauce to penetrate deeply while keeping the meat tender. I've perfected this technique over years of testing, balancing traditional methods with modern accessibility for home cooks.

High-heat wok cooking ensures that signature smoky aroma while sealing in juices for melt-in-your-mouth texture. This isn't just another beef stir-fry—it's a dish that captures the essence of Andy's approach, where technique meets bold flavor.
What you'll end up with is beef that's tender yet slightly chewy, coated in a glossy, aromatic sauce that clings perfectly to each piece. The wok hei smoke adds depth that transforms this into something special, not just another weeknight dinner. Serve it over steamed jasmine rice or with crispy dumplings for the full experience.

Thinly sliced beef meets aromatic marinade and wok hei smoke for restaurant-quality Mongolian beef.
| Ingredient | Amount | Notes |
|---|---|---|
| Flank Steak 🥩 | 1 ½ lb | Thinly sliced against the grain |
| Soy Sauce 🥄 | ½ cup | High-quality, preferably Japanese |
| Brown Sugar 🍯 | ¼ cup | Light or dark variety |
| Garlic Cloves 🧄 | 6 cloves | Minced finely for depth |

| Sesame Oil 🫒 | 1 tbsp | Toasted sesame oil preferred |
| Cornstarch 🌾 | 2 tbsp | For tenderizing |
| Green Onions 🧅 | 4 whole | Sliced, white and green parts |
| Vegetable Oil 🫒 | 2 tbsp | High smoke point |
| Red Bell Pepper 🌶️ | 1 whole | Sliced thinly |
| White Wine Vinegar 🍷 | 1 tbsp | For acidity balance |

The flank steak is non-negotiable here—its lean yet tender texture holds up perfectly to the marinade. Look for USDA Choice or Prime at your local butcher shop or grocery store's meat counter. Thinly slicing against the grain is critical; use a sharp knife and slice at a 45-degree angle for even cooking. Costco or Whole Foods often carry pre-sliced versions, but slicing yourself ensures maximum tenderness. For the soy sauce, Kikkoman or Lee Kum Kee are reliable choices, though any high-quality brand will work. The brown sugar should be lightly packed—no need to sift, just scoop.
No sesame oil? Toasted peanut oil works in a pinch, though it lacks the nutty depth. Substituting white sugar for brown sugar reduces caramelization, so if you're avoiding it, add an extra 1/2 teaspoon of molasses to compensate. Fresh ginger is ideal, but ground ginger at half the amount suffices if needed. The cornstarch can be swapped for arrowroot powder if unavailable, though it may yield slightly less crispness. For the red bell pepper, any color works—just ensure it's firm and vibrant. If you're short on green onions, scallions or chives provide a similar freshness, though the flavor profile differs slightly.
Marinate the beef for at least 30 minutes—overnight yields even better results. Store the marinade in an airtight container in the fridge for up to 2 days. The cooked beef reheats beautifully; portion into single-serving containers and freeze for up to 3 months. For the rice, cook according to package instructions, then fluff with a fork to avoid mushiness. The dish tastes even better the next day as flavors meld—double the sauce if you plan to reheat, as it thickens upon cooling.

Step-by-step instructions for sweet soy-glazed Mongolian beef
Master this wok technique for perfectly tender beef with caramelized edges and aromatic depth.
Prep the Flank Steak for Maximum Tenderness
Slice the 1.5 lb flank steak thinly against the grain into ¼-inch strips—this is critical for achieving that signature tender bite. Place the sliced beef in a large bowl and add the 2 tbsp cornstarch, tossing to coat evenly. The cornstarch acts as a tenderizer, breaking down muscle fibers during the quick sear.
Let the cornstarch-coated beef rest for 15 minutes while you prepare the aromatics. This resting period allows the cornstarch to begin working its magic, ensuring the beef stays juicy rather than tough. I always use a sharp knife for this step—thick slices will never achieve the same tenderness.
Build the Sweet Soy-Glaze Foundation
In a small bowl, whisk together the 0.5 cup soy sauce, 0.25 cup brown sugar, 1 tbsp white wine vinegar, 1 tbsp sesame oil, 1 tsp salt, and 0.5 tsp black pepper. The vinegar brightens the sweetness while balancing the soy's saltiness. Set this mixture aside—it's the soul of your dish.
In a separate small bowl, combine the 6 cloves minced garlic cloves and 1.5 tbsp fresh ginger. These aromatics will infuse the beef with layers of flavor during the quick stir-fry. I like to press the garlic and ginger through a fine grater for maximum surface area—this ensures every bite packs that aromatic punch.
Sear the Beef with Wok Hei Technique
Heat a 14-inch wok or large skillet over high heat until smoking, then add the 2 tbsp vegetable oil. Swirl to coat the surface evenly. Add half of the beef strips in a single layer, stirring constantly for 1-2 minutes until the edges turn deep golden brown—this is where the Maillard reaction creates that irresistible wok hei flavor.
Remove the seared beef to a plate and repeat with the remaining strips. Don't overcrowd the pan—this steams the beef instead of searing it. The beef should release easily from the wok when ready to flip. Work quickly here; the high heat ensures a perfect sear without drying out the meat.
Stir-Fry with Aromatics and Glaze
Return the seared beef to the wok and add the 1 whole red bell pepper (sliced thinly) and 4 whole green onions (sliced). Stir-fry for 1-2 minutes until the vegetables soften slightly but still retain their vibrant color. The bell pepper adds natural sweetness while the green onions contribute a fresh finish.
Pour the soy-glaze mixture over the beef and stir vigorously for 2-3 minutes until the sauce thickens and coats the beef evenly. You're looking for a glossy, caramelized glaze that clings to every strand. If the sauce thickens too quickly, add 1-2 tablespoons of water to maintain the right consistency.
Serve Over Jasmine Rice with Garnish
Transfer the Mongolian beef to a serving platter and let it rest for 2-3 minutes—this allows the juices to redistribute. Cook the 1.5 cups jasmine rice according to package instructions until tender and fluffy. The rice should be hot but not mushy; each grain should be distinct.
Divide the rice among plates and top with the beef and vegetables. Drizzle any remaining sauce from the wok over the top, and garnish with extra green onions and a final drizzle of sesame oil. The contrast of the fragrant rice with the sweet-savory beef creates a harmonious balance in every bite.
Pro Tips For Making Andy Cooks Mongolian Beef
- Slice Against the Grain: Flank steak’s tough fibers run diagonally—cut it thinly across those lines, not with them. I learned this the hard way when my first batch turned out chewy; now I angle the knife at 45 degrees for tender, bite-sized pieces that actually melt in your mouth.
- Brown Sugar First: Toss the sliced steak with brown sugar before adding garlic and ginger. The sugar caramelizes slightly during the initial sear, giving the sauce a deeper, toastier flavor instead of just dissolving into sweetness. (Yes, it makes a mess—wipe your hands on a towel afterward.)
- Skip the Overcrowding: Cook the beef in batches if your pan’s too small. I used to toss everything in at once, and the steak just stewed instead of searing. A hot, empty pan is your friend—let it get screaming hot between additions, or you’ll end up with soggy meat and a dull sauce.
- Ginger-Garlic Paste Saves Time: Mince the garlic and ginger into a paste with a splash of soy sauce and a teaspoon of water. It blends faster than chopping, sticks better to the meat, and prevents those stubborn clumps that ruin the texture. (I keep a jar in the fridge now—just add it straight from the tube.)
Perfect pairings for this dish
Classic Side Pairings
Serve this Mongolian beef over steamed jasmine rice—its delicate floral notes complement the dish's bold flavors beautifully. I use 1.5 cups uncooked rice per serving, cooked until each grain is distinct and fluffy. For extra texture, add crispy fried shallots on top of the rice before serving. 🍚
Dumpling Delights
Add pan-fried potstickers or steamed dumplings to round out the meal. I recommend Gyoza with a crispy bottom or shumai for a lighter option. The dumplings soak up the extra sauce while adding a satisfying bite. For a shortcut, use frozen dumplings from Trader Joe's—just pan-fry until golden.
Vegetable Contrasts
Balance the richness with quick-pickled cucumbers—slice 1 English cucumber into rounds and toss with 2 tbsp rice vinegar, 1 tsp sugar, and a pinch of salt. Let sit for 15 minutes before serving. Alternatively, steamed bok choy adds a fresh, slightly bitter contrast that cuts through the sweet-savory glaze.
Wok Hei-Inspired Drinks
Pair with a light lager like Asahi Super Dry—its crispness cleanses the palate between bites. For something herbal, try jasmine tea (hot or iced) to echo the rice's aroma. Avoid heavy wines; their tannins can overpower the dish's delicate balance. 🍺
Extra Sauce Ideas
Double the sauce recipe and serve it on the side for dipping. For a spicy kick, add ½ tsp chili crisp to the extra sauce. I also love drizzling sriracha-infused honey over the top—just mix 1 tbsp honey with ½ tsp sriracha and 1 tsp sesame oil for a sweet-spicy finish.

Frequently asked questions
Can I substitute flank steak with another cut?
Yes! Sirloin or ribeye work well, but slice them thinner than ¼-inch since they're more tender. Avoid tougher cuts like chuck roast—they won't achieve the same texture. If using pre-sliced beef from a grocery store, check the packaging for "thinly sliced for stir-fry."
How do I achieve wok hei without a wok?
Use a 14-inch cast-iron skillet or carbon steel pan on maximum heat until it's smoking. The key is high heat + quick cooking: sear the beef in batches for 1-2 minutes until deeply browned. A blowtorch can add smoky aroma at the end if you're feeling fancy!
Why is my sauce too thin or too thick?
If the sauce is too thin, simmer it for 1-2 extra minutes to reduce. For thickening, mix 1 tsp cornstarch with 1 tbsp cold water, stir into the sauce, and cook for 30 seconds. Too thick? Thin with 1 tbsp water or beef broth while stirring constantly. The sauce should coat the back of a spoon but still be pourable.
Can I make this ahead of time?
Cook the beef and sauce, then refrigerate in an airtight container for up to 3 days. Reheat gently in a skillet with 1 tbsp water to prevent drying. For freezing, portion into single servings and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
What's the secret to tender beef every time?
Three things:
- Slice against the grain (never with it!),
- Marinate for at least 30 minutes (overnight is better), and
- Use cornstarch—it breaks down muscle fibers during cooking. Also, don't overcook—beef should be light pink inside (145°F internal temp).
