Takeout Style Mongolian Beef Recipe Ingredients

To make this recipe, we will need the following ingredients:

• 1½ lbs flank steak or sirloin, thinly sliced against the grain: These lean, flavorful cuts cook quickly and stay tender when sliced thin. Cutting against the grain keeps the beef from getting chewy — essential for that classic takeout texture.
• 1 teaspoon baking soda: A simple tenderizing trick! Baking soda helps break down the meat fibers, making even tougher cuts more melt-in-your-mouth tender — especially useful for home-cooked stir-fry.
• ¼ cup cornstarch: Lightly coats the beef to help it crisp up during cooking and naturally thickens the sauce into that signature glossy, clingy texture.
• 2 tablespoons vegetable oil, divided: Neutral oil with a high smoke point — ideal for stir-frying. It helps sear the beef and build that flavorful browned exterior.
• 3 cloves garlic, minced: Adds bold, aromatic depth to the sauce. Garlic gives Mongolian beef its savory backbone and plays perfectly with the sweetness of the brown sugar. Sub: ¾ teaspoon garlic powder if using dried.
• 1 tablespoon fresh ginger, grated: Adds brightness, warmth, and that subtle zing that balances the rich sauce. Fresh ginger makes the dish pop. Sub: ½ teaspoon ground ginger if using dried.
• ½ cup low-sodium soy sauce: Brings deep umami flavor and the right amount of salty savoriness. Low-sodium keeps the dish from being overpowering.
• ¼ cup brown sugar, packed: Sweetens and thickens the sauce while giving it that sticky, caramelized finish — a signature part of Mongolian beef’s takeout-style flavor.
• ¼ cup water: Loosens the sauce slightly and helps dissolve the sugar and soy base for even coating and bubbling during the simmer.
• 1 teaspoon toasted sesame oil (optional): Adds nutty, aromatic depth — a little goes a long way. Optional, but it adds that extra layer of richness and authenticity.
• 2 green onions, sliced — white and green parts separated: The white parts are cooked with the beef for mild onion flavor, while the green tops are added at the end for color and freshness.
• 1–2 tablespoons chili crisp: Adds a punch of umami heat with crispy garlic, chili flakes, and oil. It brings both flavor and texture — adding mild spice, richness, and those irresistible little crunchy bits that cling to the beef. Totally optional, but highly recommended!
• Optional garnish: sesame seeds, more green onions: Adds visual contrast, a little crunch, and a restaurant-style finish. Sesame seeds elevate the presentation and pair well with the sesame oil.

Steps to Make Mongolian Beef

Once you’ve gathered your ingredients, we will use the following process:

Thin Slice Beef

Cut steak against the grain into small slices or chunks. Pat dry.

Toss in Cornstarch and Baking Soda

Toss in cornstarch and baking soda, coat evenly.

Make Sauce & Toss

Stir soy sauce, brown sugar, chili crisp, garlic, ginger. Stir well.

Fry

Heat oil in large skillet or wok until hot. Add beef in small batches, flipping often, until fried crunchy brown. Add dried chilies at end of cooking if using.

Cook beef and sauce

Add sauce to pan with garlic and heat. If sauce is too thin, thicken with cornstarch slurry. Mix 1 tablespoon water and 1 tablespoon cornstarch in a small bowl until well mixed. Add dried chilies if using, and dump sauce over beef, toss beef to coat. Heat until thickened, about 3-4 minutes.

Garnish & Enjoy

Sprinkle with sesame seeds, chopped green onions, if desired. Remove from heat and serve over rice or noodles. Serve immediately, and enjoy!

Tips and Tricks to Perfect Mongolian Beef

Slice the beef thin (really thin). The thinner the slices, the quicker they cook and the more tender they stay. Partially freezing the steak for 15–20 minutes makes it way easier to slice. If using thin cut top loin, cut against the grain into thin strips.

Use high heat. You want that nice golden sear on the beef, not a slow steam. Cook in batches if needed so the pan stays hot and the beef browns instead of boiling.

Cornstarch is key. It helps the beef crisp up and thickens the sauce to that glossy, restaurant-style finish. Don’t skip it!

Don’t leave sauce simmering long. The sugar in the sauce can go from perfectly caramelized to burned fast. Keep an eye on it and stir often once it starts bubbling.

Customize the heat. Add a pinch of red pepper flakes or a dash of sriracha if you like things spicy. The base recipe is mild and kid-friendly.

Serve it fresh. Mongolian beef is best right after cooking while the beef is still crispy and the sauce is hot and thick. It reheats well but loses that freshly-seared texture.

Easy Mongolian Beef FAQs

Thin cut top loin, flank steak, sirloin, or even skirt steak work great. You want a lean cut that can be sliced thin and cooked quickly.

You can, but it’ll be more like a Mongolian-style beef bowl than traditional sliced Mongolian beef. Still delicious though — just cook the beef, then add the sauce.

Cut the brown sugar down by 1–2 tablespoons, or add a splash of rice vinegar or lime juice to balance the sweetness with acidity.

Yes! Just swap the soy sauce for tamari or coconut aminos, and make sure your cornstarch and other ingredients are certified gluten-free.

You can slice the beef and mix the sauce up to a day ahead. Cook everything fresh for best texture, but leftovers reheat well for up to 3 days in the fridge.
