What Is Mongolian Beef?

Despite its name, Mongolian beef is not actually a traditional dish from Mongolia. It was popularized by Chinese-American restaurants and is widely associated with P.F. Chang’s style cuisine. The dish features thinly sliced beef — typically flank steak — that is lightly coated in cornstarch, flash-fried until crispy, then tossed in a bold sauce made from soy sauce, hoisin, brown sugar, garlic, and ginger.

The result is an irresistible combination of sweet, salty, and umami-rich flavors with a melt-in-your-mouth texture. Green onions are classically added at the end for freshness and color.

How to Make Mongolian Beef: Step-by-Step Instructions

Follow these simple steps to make restaurant-quality Mongolian beef at home. The key is to work quickly with high heat — just like a real wok kitchen.

Step 1: Slice and Coat the Beef

Freeze the flank steak for 20–30 minutes before slicing — this firms it up and makes thin slicing much easier.
Using a sharp knife, slice the steak into thin strips (about 1/4 inch thick) cutting against the grain. This is the most important step for tender beef.
Pat the strips dry with paper towels to remove excess moisture.
Toss the beef strips in cornstarch until each piece is evenly coated. Shake off any excess. Set aside.

Step 2: Make the Mongolian Beef Sauce

In a small bowl or measuring cup, whisk together: soy sauce, brown sugar, water, hoisin sauce, sesame oil, minced garlic, grated ginger, and red pepper flakes (if using).
Stir until the brown sugar is dissolved. Set the sauce aside.
In a separate tiny bowl, mix 1 tablespoon cornstarch with 2 tablespoons cold water to create a slurry. Set aside.

Step 3: Fry the Beef

Heat vegetable oil in a large wok or heavy-bottomed skillet over HIGH heat until the oil is shimmering and almost smoking.
Add the beef strips in a SINGLE LAYER — do not overcrowd the pan! Cook in 2–3 batches if needed.
Fry each batch for 1–2 minutes per side without moving, until a golden-brown crust forms. Transfer to a plate lined with paper towels.

PRO TIP: Overcrowding the pan causes the beef to steam instead of fry, resulting in soggy rather than crispy beef. Always cook in batches for best results.

Step 4: Build the Sauce

In the same wok, reduce heat to medium-high. Add the sauce mixture and bring it to a gentle simmer.
Cook for 2–3 minutes, stirring occasionally, until the sauce starts to reduce and darken.
Pour in the cornstarch slurry and stir continuously. The sauce will thicken noticeably within 30–60 seconds.

Step 5: Combine and Finish

Return the fried beef to the wok and toss to coat every piece in the thick, glossy sauce.
Add the green onion pieces and toss for another 30 seconds just to warm them.
Remove from heat and plate immediately over steamed rice.
Garnish with toasted sesame seeds and extra green onion slices. Serve hot.

Expert Cooking Tips for the Best Mongolian Beef

These pro tips will take your homemade Mongolian beef from good to absolutely exceptional:

Tip 1: Always Slice Against the Grain

Cutting against the grain shortens the muscle fibers, making the beef significantly more tender. Look for the direction the lines run in the meat and slice perpendicular to them.

Tip 2: Use High Heat

Mongolian beef is a stir-fry dish that needs very high heat to achieve that restaurant-style sear. A cast iron skillet or a wok is ideal. Don’t be afraid to crank up the burner.

Tip 3: Don’t Skip the Cornstarch

Cornstarch is a non-negotiable in this recipe. It creates a slightly crispy crust on the beef that holds the sauce and gives the dish its signature texture. It also helps thicken the sauce naturally.

Tip 4: Taste and Adjust the Sauce

Before adding the beef back in, taste your sauce. Want it sweeter? Add a touch more brown sugar. Want more depth? Add a dash more hoisin. This is your recipe — make it yours.

Tip 5: Use Low-Sodium Soy Sauce

Regular soy sauce can make this dish very salty. Low-sodium soy sauce gives you the same umami punch without overwhelming saltiness. It also allows you to control the seasoning better.

Mongolian Beef Variations & Substitutions

One of the best things about this recipe is how versatile it is. Here are some popular variations:

Different Protein Options

Mongolian Chicken: Substitute thinly sliced chicken breast or thigh — equally delicious.
Mongolian Pork: Use pork tenderloin sliced thin for a slightly different but wonderful flavor profile.
Mongolian Tofu: Press extra-firm tofu, cube it, coat in cornstarch, and fry — great for a vegetarian version.
Mongolian Shrimp: Use large shrimp with the same coating — reduce the cooking time to 1 minute per side.

Add Vegetables

Broccoli — a classic pairing; blanch separately and toss with beef in sauce
Bell peppers (red or yellow) — add color and sweetness
Snap peas or snow peas — add fresh crunch
Mushrooms — shiitake or cremini work beautifully

Make It Spicy

To create a spicy Mongolian beef, increase red pepper flakes to 1 full teaspoon, add 1 tablespoon of sambal oelek or sriracha to the sauce, and finish with a drizzle of chili oil when plating.

What to Serve with Mongolian Beef

Mongolian beef pairs beautifully with a variety of sides. Here are the best options:

Side Dish	Why It Works
Steamed Jasmine Rice	Classic pairing; the rice soaks up the sauce perfectly
Fried Rice	Adds texture and makes it an all-in-one satisfying meal
Lo Mein Noodles	Great for a noodle bowl presentation
Cauliflower Rice	Perfect low-carb option
Steamed Broccoli	Balances the richness with fresh green flavor
Asian Cucumber Salad	Adds a cool, refreshing contrast to the savory beef

Storage, Reheating & Meal Prep Tips

Refrigerator Storage

Store leftover Mongolian beef in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen overnight, making leftovers taste even better the next day.

Freezer Storage

This dish freezes well! Let it cool completely, then transfer to a freezer-safe bag or container. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheating

Reheat in a skillet over medium heat with a splash of water or broth to loosen the sauce. Microwaving works in a pinch — cover loosely and heat in 60-second intervals, stirring in between.

Meal Prep

You can prep several components ahead of time to make this recipe even faster on a busy weeknight: slice and marinate the beef, whisk together the sauce (store in a jar), and cook the rice in advance. When ready to eat, the final dish comes together in under 15 minutes.

Frequently Asked Questions (FAQ)

Can I use a different cut of beef for Mongolian beef?

Yes! While flank steak is the most traditional cut, you can also use skirt steak, sirloin, or even ribeye. The key is to slice the beef very thin and always against the grain. Avoid stew meat or chuck — these cuts require low-and-slow cooking to become tender.

Why is my Mongolian beef sauce not thickening?

If your sauce is not thickening, it is likely that the heat is too low or you need more cornstarch slurry. Make sure the sauce is at a steady simmer before adding the slurry, and stir continuously as you pour it in. Wait at least 60 seconds before adding more thickener.

Is Mongolian beef gluten-free?

Traditional Mongolian beef is not gluten-free due to the soy sauce. To make it gluten-free, substitute tamari or coconut aminos for the soy sauce, and use a certified gluten-free hoisin sauce. Check all labels carefully.

Can I make Mongolian beef ahead of time?

You can make the sauce and prep the beef ahead of time, but for the best texture, fry the beef and combine everything fresh. If you make the full dish in advance, reheat it in a skillet rather than the microwave to help restore some of the beef’s crispiness.

What makes Mongolian beef different from beef with broccoli?

Mongolian beef is sweeter and saucier, with a bolder garlic-ginger flavor profile and a focus on green onions. Beef with broccoli has a lighter, more savory oyster-sauce-based sauce and obviously features broccoli as a key component. Both are delicious Chinese-American classics.

Conclusion

This easy Mongolian beef recipe is everything you want from a takeout-style dish — rich, savory, slightly sweet, and loaded with bold garlic-ginger flavor — made right in your own kitchen in 30 minutes or less.
