How to Make Simple Mongolian Beef Recipe

Step 1: Prep and Coat the Beef

Start by slicing the flank steak thinly against the grain—this makes the beef tender and easier to chew. Toss these slices in cornstarch; this simple step is critical for that signature crusty texture once they hit the pan. Prepping everything first is key, because once you start cooking, things move quickly!

Step 2: Whisk Together the Sauce

While your beef is sitting, combine the brown sugar, garlic, crushed red pepper flakes if using, fresh ginger, soy sauce, and water in a separate bowl. Whisking these ingredients together ensures the flavors will be perfectly melded and your sauce silky and balanced.

Step 3: Heat the Oil and Sear the Beef

Heat 2 tablespoons of olive oil in a large skillet over medium-high heat until it’s very hot—this is where the magic begins. Cook the beef in two batches so it browns evenly; let each batch sear without disturbing it for about a minute per side before flipping. This step locks in flavor and prevents steaming, giving you that coveted crisp edge.

Step 4: Combine Sauce and Beef

After both batches have browned, add the sauce to the skillet and bring it to a bubble, scraping up those delicious browned bits on the bottom. Toss in the scallions and return the beef to the pan. Stir everything together and let it simmer for a few minutes until the sauce thickens and beautifully coats the steak.

The meat is scattered with small pieces of green onions that add a fresh green color. The pan has a dark, shiny layer of sauce coating the meat, giving it a glossy look that makes it appear flavorful and moist.

Garnishes

Scallions are already part of this recipe, but to elevate it further, sprinkle some toasted sesame seeds or add fresh cilantro leaves. These garnishes add contrasting texture and a pop of freshness that brighten every bite.

Side Dishes

This Simple Mongolian Beef Recipe pairs wonderfully with steamed jasmine rice or fluffy white rice to soak up the flavorful sauce. For a lighter crunch, serve alongside stir-fried vegetables like broccoli, snap peas, or bell peppers to balance the richness.

Creative Ways to Present

Why not transform this dish into a satisfying lettuce wrap? Spoon the beef and scallions into crisp lettuce leaves, and add a drizzle of sriracha mayo for a fun, handheld twist. You can also serve it over cauliflower rice for a low-carb option that still offers plenty of flavor.

Make Ahead and Storage

Storing Leftovers

Leftover Simple Mongolian Beef keeps well in an airtight container in the refrigerator for up to 3 days. Just make sure to cool it completely before sealing to maintain the sauce’s texture.

Freezing

You can freeze this dish by placing cooled portions in freezer-safe containers or bags. It will hold well for up to 2 months. When freezing, it’s best to leave out the scallions and add fresh ones when reheating for a brighter flavor.

Reheating

Reheat leftovers gently on the stovetop over medium heat or in the microwave until warmed through. If the sauce seems a bit thick or sticky, add a splash of water or soy sauce to loosen it up and bring back that silky consistency.

FAQs

Can I use a different cut of beef?

Absolutely! While flank steak is ideal for its tenderness and flavor, skirt steak or sirloin can also work well if thinly sliced. Just be sure to cut against the grain to keep the beef tender.

Is it possible to make this recipe gluten-free?

Yes! Simply substitute the regular soy sauce with tamari or another gluten-free soy sauce alternative, and you’ll have a delicious gluten-free version of this recipe.

Can I make this dish vegetarian or vegan?

Definitely. Swap the beef for tofu, tempeh, or even portobello mushrooms, and follow the sauce recipe as is. Adjust cooking times as necessary to ensure your plant-based protein develops a nice texture.

How spicy is the dish?

This Simple Mongolian Beef Recipe has a mild heat level by default, thanks to the optional crushed red pepper flakes. You can adjust the amount or omit it entirely if you prefer no spice at all.

Can I prep parts of this recipe ahead of time?

For sure! You can slice the beef and toss it in cornstarch up to a day in advance and store it in the fridge. The sauce can also be mixed beforehand, making weeknight cooking a breeze.
