Essential Ingredients for Mongolian Beef
Flank Steak: This is the star of your Mongolian Beef, providing lean, flavorful meat that slices beautifully thin for quick cooking. I always trim any excess fat to ensure tenderness, and marinating it briefly helps it absorb those incredible flavors. Choose a fresh cut from your butcher for the best results—it’s worth it for that melt-in-your-mouth texture.
Soy Sauce and Brown Sugar: The backbone of the sauce, low-sodium soy sauce adds umami without overpowering saltiness, while brown sugar brings the sticky sweetness that defines Mongolian Beef. Together, they create that glossy caramelized coating we all love. I’ve found using dark brown sugar amps up the richness just a touch.
Garlic and Ginger: Fresh minced garlic and grated ginger infuse the Mongolian Beef with aromatic warmth and a subtle heat that balances the sweetness. These pantry staples are key to authenticity—don’t skip them, as they make the dish pop with flavor. In my kitchen, I grate the ginger for even distribution.
How to Make Mongolian Beef
Prepare the Beef
Start by slicing your flank steak against the grain into thin strips—this ensures the Mongolian Beef stays tender and doesn’t toughen up. Pat the slices dry with paper towels, then toss them in a bowl with cornstarch, a pinch of salt, and black pepper until evenly coated. In my experience, letting it sit for 10 minutes helps the coating adhere perfectly for that crispy sear. Heat oil in a wok or large skillet over high heat, and add the beef in a single layer to avoid steaming.
Cook the Beef and Aromatics
Stir-fry the coated beef for about 2-3 minutes until browned on all sides, then remove it to a plate—this step locks in the juices for succulent Mongolian Beef. In the same pan, lower the heat to medium and sauté minced garlic and ginger for just 30 seconds until fragrant, being careful not to burn them. The aroma will fill your kitchen, making it feel like a cozy night in. Now, pour in the soy sauce, brown sugar, and a splash of water, stirring to dissolve everything into a bubbly sauce.
Combine and Finish the Mongolian Beef
Return the cooked beef to the pan, tossing it in the simmering sauce for 1-2 minutes until everything is glossy and thickened—this is where the magic happens for your Mongolian Beef. Slice green onions and stir them in at the end for freshness and color. Taste and adjust with a bit more sugar if needed; I like mine with a slight kick, so a dash of red pepper flakes does the trick. Serve hot over steamed rice for the ultimate comfort meal.

Pro Tips for the Best Mongolian Beef
Slice Against the Grain: Always cut your steak perpendicular to the muscle fibers for tender Mongolian Beef that isn’t chewy.
Don’t Overcrowd the Pan: Cook in batches to get a good sear; overcrowding steams the beef instead of crisping it.
Use Fresh Aromatics: Grate ginger and mince garlic right before cooking for the brightest flavor in your Mongolian Beef.

You Must Know
- Mongolian Beef is not actually from Mongolia; it’s an American-Chinese dish inspired by stir-fry techniques.
- The cornstarch coating is crucial for the signature crispy texture on the outside while keeping the inside juicy.
- Balance is key—taste the sauce midway and adjust sweetness or salt to your preference.
- High heat is essential for that wok hei flavor, so use a hot pan or wok if possible.
How to Store Mongolian Beef
Let your Mongolian Beef cool completely before transferring it to an airtight container; it keeps in the fridge for up to 3 days without losing much texture. For longer storage, freeze portions in freezer bags for up to 2 months, though the sauce might separate a bit upon thawing. To reheat, warm it in a skillet over medium heat with a splash of water to revive the glossiness—microwaving works too but stir halfway for even heating.
Customizing Your Mongolian Beef
If you’re looking to switch things up, swap flank steak for skirt steak or even chicken for a lighter twist on Mongolian Beef. Add veggies like bell peppers or broccoli during the sauce step for extra nutrition without complicating the recipe. For a gluten-free version, use tamari instead of soy sauce—I’ve tried it and it tastes just as amazing.
What to Serve with Mongolian Beef
Pair this Mongolian Beef with steamed jasmine rice to soak up the incredible sauce, or try cauliflower rice for a low-carb option. A simple cucumber salad with sesame dressing adds crunch and freshness to balance the richness. For drinks, iced green tea or a light beer complements the Asian flavors perfectly. Don’t forget steamed broccoli on the side—it’s a classic match that makes the meal feel complete.

- 03 1 Tbsp unsalted butter
- 04 2 Tbsp neutral oil (divided*)
- 05 1 lb flank steak (thinly sliced against the grain*)
- 06 1/4 cup corn starch
- 07 1/3 cup green onions (thickly sliced (from 4 stems))

Instructions
Place beef slices in a bowl, add cornstarch and stir to completely coat.
In a bowl, combine the ingredients for the sauce and stir until well combined, set aside.
In a large skillet or wok, heat 1 Tbsp oil with 1 Tbsp butter over medium/high heat. Once the skillet is hot, add the carrot and peppers and stir fry until crisp-tender or to your desired tenderness, stirring frequently. Remove the vegetables to a separate plate.
Increase to high heat and add 1 Tbsp oil. Once hot, add the beef and sear for about 2 minutes per side to create a crispy coating. Add more oil if the skillet seems dry. Do not crowd the pan and cook the beef in batches if needed.
Add the vegetables back into the skillet with the green onion. Add the sauce and stir to combine. Turn heat to medium/low and simmer until the sauce thickens, about 3 minutes. Garnish with sesame seeds if desired and serve.

Frequently Asked Questions About Mongolian Beef
Can I make Mongolian Beef ahead of time?
Yes, you can prep the beef and sauce separately up to a day in advance, then stir-fry when ready. This saves time on busy nights, and the flavors even meld a bit more. Just store everything in the fridge until cooking.
How long does Mongolian Beef last in the fridge?
Mongolian Beef stays fresh for 3-4 days when stored properly in an airtight container. Beyond that, the texture might soften, so freezing is better for longer storage. Always reheat thoroughly to enjoy it safely.
Is Mongolian Beef spicy?
Traditional Mongolian Beef isn’t spicy, but you can add red pepper flakes or sriracha to the sauce for heat. I like a mild kick, so start small and adjust to taste. It’s flexible for all palates.
What’s the best cut of beef for Mongolian Beef?
Flank steak is ideal for this Mongolian Beef because it’s lean and slices thinly for quick cooking. Sirloin works too if you can’t find flank, but avoid tougher cuts like round. Thin slicing is key either way.
Can I use ground beef for Mongolian Beef?
Absolutely, ground beef is a great shortcut for quicker prep in your Mongolian Beef. Brown it first, then proceed with the sauce. Check out our ground beef and broccoli recipe for similar inspiration.
How do I make Mongolian Beef less sweet?
To tone down the sweetness in Mongolian Beef, reduce the brown sugar by a tablespoon and add more soy sauce or a splash of rice vinegar. Taste as you go—I’ve found this keeps the balance perfect. Fresh lime juice at the end brightens it up too.
Is Mongolian Beef gluten-free?
It can be! Swap soy sauce for gluten-free tamari, and ensure your cornstarch is certified gluten-free. This version of Mongolian Beef maintains all the flavor without the worry.
Can I air fry Mongolian Beef?
Yes, coat and air fry the beef at 400°F for 8-10 minutes, then toss in the stovetop sauce. It’s a hands-off twist on traditional Mongolian Beef. For more air fryer ideas, see our air fryer chicken skewers.
