Essential Ingredients for Mongolian Beef
Flank Steak: This lean cut is the star of Mongolian Beef, offering tenderness when sliced thin and cooked quickly. I always choose grass-fed for extra flavor, but any flank works great. It absorbs the sauce beautifully, creating that signature glossy finish. In my experience, freezing it briefly makes slicing a breeze.
Soy Sauce and Brown Sugar: These form the backbone of the Mongolian Beef sauce, blending salty umami with caramelized sweetness. Low-sodium soy keeps it balanced, while dark brown sugar adds depth and stickiness. Together, they transform simple beef into something extraordinary—don’t skip the ginger for that zing.
Garlic and Green Onions: Fresh garlic infuses the Mongolian Beef with aromatic punch, while green onions add a fresh, crisp contrast at the end. I mince the garlic finely to ensure even distribution in the sauce. These elevate the dish from good to unforgettable, providing layers of texture and taste.
How to Make Mongolian Beef
Prepare the Beef
Start by slicing your flank steak against the grain into thin strips—this ensures tenderness in the final Mongolian Beef. Toss the slices with cornstarch, a pinch of salt, and black pepper to create that crispy coating. In my kitchen, I let it sit for 10 minutes while prepping the sauce; it makes all the difference in texture. Heat oil in a wok or large skillet over medium-high, then add the beef in batches to avoid overcrowding. Sear for 1-2 minutes per side until browned but still pink inside. Remove and set aside, keeping that pan hot for the next step.
Cook the Sauce
Now, lower the heat and sauté minced garlic and ginger in the same pan until fragrant—about 30 seconds, no more, to prevent burning. Pour in soy sauce, brown sugar, water, and a splash of sesame oil, stirring until the sugar dissolves into a bubbly glaze. Here’s the thing: taste it here and adjust sweetness if needed. Let it simmer for 2 minutes to thicken, creating the glossy sauce that defines great Mongolian Beef. The aroma will have everyone hovering nearby.
Combine and Finish
Return the seared beef to the pan, tossing everything to coat evenly in the sauce—cook for another 2-3 minutes until the Mongolian Beef is glossy and cooked through. Slice green onions and stir in half for freshness, reserving the rest for garnish. For extra flair, I sometimes add red pepper flakes for a mild kick. Serve hot over steamed rice, and watch it disappear. This step brings it all together into a cohesive, mouthwatering dish.

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, maintaining that great texture. For reheating, warm in a skillet over medium heat with a splash of water to revive the sauce, or microwave in short bursts. Freezing works too, up to a month—just thaw overnight and reheat gently.
Customizing Your Mongolian Beef
Swap flank for sirloin if you prefer, or go ground beef for a quicker version like in this Mongolian Ground Beef Noodles. Add broccoli or bell peppers during the sauce step for veggies. For gluten-free, use tamari instead of soy sauce. These tweaks keep the Mongolian Beef essence while suiting your needs.
What to Serve with Mongolian Beef
Steamed jasmine rice soaks up the incredible sauce perfectly. Add a side of stir-fried broccoli or egg rolls for crunch. For a fresh contrast, try cucumber salad. Don’t forget iced green tea or a light beer to complement the flavors. If you’re into bowls, layer it with fried rice for a complete meal.

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.
