Mongolian Beef Recipe

This Mongolian beef recipe is about to become your new favorite weeknight dinner! Last Tuesday night, I was staring at my fridge trying to figure out what to make for dinner when Amy piped up from the kitchen table, "Mom, can we get that yummy beef from the Chinese place?"

You know what she was talking about - that sweet, sticky beef that somehow manages to be both tender and crispy at the same time. But instead of ordering out, I decided to try making it myself. And let me tell you, after three attempts and some serious trial and error, I've cracked the code!

This Mongolian beef recipe delivers everything you love about the restaurant version but better - because it's made with real ingredients in your own kitchen. The beef comes out incredibly tender thanks to a simple marinade trick I learned in culinary school, and the sauce? It's that perfect balance of sweet and savory that makes everyone come back for seconds.

What I love most is how quick it comes together. In just 30 minutes, you've got dinner that looks like you spent hours on it. Bradley always gets excited when he sees me pulling out the wok because he knows something good is about to happen.

Mongolian Beef Ingredients You'll Need

Beef Marinade

• 1 lb flank steak - sliced into 1½ inch pieces across the grain
• ½ teaspoon baking soda - this is the secret to super tender beef
• 1 tablespoon cornstarch
• 1 tablespoon Shaoxing wine (or dry sherry if you can't find it)
• 1 tablespoon water
• 1 tablespoon soy sauce
• ¼ teaspoon white pepper
• 1 tablespoon vegetable oil
• ½ cup cornstarch - for dredging

Mongolian Beef Sauce

• ¼ cup brown sugar - I use light brown sugar
• ½ cup beef broth - low sodium works great
• ¼ cup soy sauce - regular soy sauce
• 2 teaspoons dark soy sauce - this adds that deep color
• 1 tablespoon oyster sauce - don't skip this!
• 1 teaspoon sesame oil

Cornstarch Slurry

• 1 tablespoon cornstarch
• 2 tablespoons water

Stir Fry Components

• ⅓ cup vegetable oil - for frying the beef
• ½ small yellow onion - thinly sliced
• 2 teaspoons fresh ginger - minced
• 4 cloves garlic - minced
• 6 dried chili peppers - adjust to your heat preference
• 5 stalks green onion - white and green parts separated, cut into 2-inch pieces

How To Make Mongolian Beef Step By Step

Preparing The Beef

1. Marinate the beef properly. In a large mixing bowl, combine the sliced flank steak with baking soda, cornstarch, Shaoxing wine, water, soy sauce, white pepper, and vegetable oil. Mix everything together until the beef is well coated and let it marinate for at least 30 minutes. Here's what I've learned - the baking soda is crucial for breaking down the protein fibers. It might seem weird, but trust me on this one!
2. Make your sauce ahead. In a medium bowl, whisk together the brown sugar, beef broth, soy sauce, dark soy sauce, oyster sauce, and sesame oil until the sugar dissolves completely. Set this aside - having everything ready makes the actual cooking so much smoother.

Cooking The Perfect Mongolian Beef

3. Dredge each piece of beef. Place the ½ cup of cornstarch in a large bowl. Take each piece of marinated beef and coat it evenly in the cornstarch, then shake off any excess. I like to do this step right before cooking so the coating doesn't get soggy.
4. Fry the beef in batches. Heat the vegetable oil in a wok or large skillet over medium-high heat until it's nice and hot. Working in small batches (don't overcrowd!), cook the beef pieces in a single layer for about 1 minute on each side until they're golden and crispy. Remove the beef and set aside. The key here is not to move the beef around too much - let it get that beautiful crust!

Building The Mongolian Beef Stir Fry

5. Create your flavor base. Drain most of the oil from the wok, leaving about 1 tablespoon. Heat it over medium heat, then add the sliced onion, minced ginger, minced garlic, dried chili peppers, and the white parts of the green onions. Stir-fry for about 1 minute until everything smells amazing.
6. Add the sauce and thicken. Pour in your prepared sauce and bring it to a gentle simmer for 1-2 minutes. Mix the cornstarch and water together to make a slurry, then slowly stir it into the simmering sauce until it thickens to coat the back of a spoon.
7. Bring it all together. Add the crispy beef back to the wok along with the green parts of the green onions. Toss everything together for about 30 seconds until the beef is coated in that gorgeous sauce and the green onions are just wilted.
8. Serve immediately. This Mongolian beef is best enjoyed right away while the beef is still crispy and the sauce is hot. Serve it over steamed rice and watch everyone's faces light up!

Storage & Reheating Your Mongolian Beef

Store any leftovers in an airtight container in the refrigerator for up to 3 days. I'll be honest - the beef won't be quite as crispy the next day, but it's still absolutely delicious.

For reheating, I prefer using a skillet over medium heat for about 2-3 minutes, stirring frequently. This helps maintain some of that texture better than the microwave. You can also reheat in the microwave in 30-second intervals, stirring between each one.

The flavors actually develop even more overnight, so leftover Mongolian beef makes for an incredible lunch the next day!

Tips For The Best Mongolian Beef Every Time

• Slice against the grain - This is crucial for tender beef. Look for the direction of the muscle fibers and cut perpendicular to them.
• Don't skip the marinade time - I know 30 minutes seems long when you're hungry, but it makes such a difference in tenderness.
• Get your wok really hot - You want that nice sear on the beef, which only happens with proper heat.
• Work in batches - Overcrowding the pan will steam the beef instead of giving it that crispy coating we're after.
• Have everything prepped first - Once you start cooking, things move fast! Amy learned this the hard way when she tried to help me chop vegetables mid-stir fry.

How do you know when your oil is hot enough? I drop a small piece of cornstarch-coated beef in - if it sizzles immediately, you're good to go!

Mongolian Beef Recipe Variations

• Make it spicier - Add more dried chilies or include some fresh sliced jalapeños with the aromatics
• Vegetable additions - Bell peppers, snap peas, or broccoli work beautifully in this dish
• Different proteins - This sauce works amazingly with chicken thighs or even firm tofu
• Adjust the sweetness - Use more or less brown sugar depending on your family's preferences
• Make it gluten-free - Substitute tamari for soy sauce and use rice wine instead of Shaoxing wine

Bradley actually suggested adding bell peppers once, and now it's become our go-to variation when we want extra veggies!
