Mongolian beef

Total: 30 mins | Serves: 2
That first bite of crispy, glossy Mongolian beef, the way the sweet-spicy sauce clings to every tender slice of flank steak — it's enough to make you reconsider takeout forever. I used to think this dish required a wok at screaming heat and a laundry list of hard-to-find sauces, until I tried this version with little more than a skillet, a little cornstarch, and one egg white to keep the beef silky. The trick isn't in the heat or the pantry; it's in that single pinch of salt that makes the meat taste like it's been marinated for hours, and the sesame oil that whispers richness at the very end. You can skip the cornstarch-heavy wok shuffle and still end up with beef that crackles like tempura, thanks to that egg white glaze that crisps up just as the meat hits the oil. A handful of garlic and a whisper of ginger do the heavy lifting for flavor, while the sauce comes together in seconds — no complicated reductions, no trips to the Asian aisle for obscure ingredients. This recipe, shared by Good Food member lnguyen, proves you don’t need a restaurant kitchen to nail that glossy, caramel-kissed crust and tender beef that melts on the tongue.

Mongolian beef

Ingredients

  • One pound flank steak
  • One tablespoon cornstarch
  • One egg white
  • A small pinch of salt
  • One teaspoon sesame oil
  • Vegetable oil for frying (approximately one cup)
  • One tablespoon minced garlic
  • Half a teaspoon of grated ginger
  • Three tablespoons hoisin sauce
  • Two tablespoons water
  • One tablespoon dark soy sauce
  • Two teaspoons rice vinegar
  • Half a teaspoon Chinese five-spice powder
  • A quarter teaspoon chilli paste (adjust to taste)
  • One to three teaspoons dark brown sugar
  • Two teaspoons vegetable oil
  • Two large green onions, sliced
  • One small white onion, diced
  • One teaspoon fresh coriander leaves for garnish

Instructions

Step 1

Slice the flank steak against the grain into thin strips about ¼-inch wide and 2 inches long. Lay the pieces on a cutting board so they’re easy to grab one at a time. In a small, shallow bowl, pour ¼ cup of the marinade you’ve already mixed up. Dip each strip in the marinade, turning to coat every side. Let the beef rest on a plate while you wipe your hands and clear space—about 30 minutes gives the cornstarch time to grab onto the meat and set up a little crust you’ll love later.

Step 2

Here’s the expanded version of Step 2 with clear, engaging cooking instructions: --- Pour the vegetable oil into a small saucepan and set it over medium-low heat. Let it warm up for about 30 seconds—you’re aiming for it to shimmer but not smoke. While it heats, grab a small bowl and measure out your other sauce ingredients so they’re ready to go. Keep an eye on the oil; when it’s hot enough, you’ll just start to see a faint haze rising from the surface.

Step 3

Mince up about a tablespoon of fresh ginger and a clove of garlic until they’re finely minced—no big chunks here. Toss them into the same hot pan you used for the beef and stir for about 30 seconds just until the garlic turns pale golden and fragrant. Now drop in the soy sauce, oyster sauce, hoisin, rice wine, and cornstarch slurry, leaving the sugar behind for a moment. Keep the heat medium-high and let the sauce bubble and thicken for roughly 60 seconds, until it’s glossy and coats the back of a spoon.

Step 4

In a small bowl, whisk together the brown sugar and sauce until there are no lumps left. Then, set your skillet over medium heat and let the sauce come to a gentle simmer—just a few bubbles at first. Once it’s bubbling steadily, crank the heat up to medium-high and let it boil for about 2 minutes, stirring often so it doesn’t scorch. You’ll know it’s ready when it thickens into a glossy, syrupy coat that leaves a clear path when you drag a spoon through the middle.

Step 5

Let the beef rest for a few minutes off the heat so the juices settle back in. While it’s out of the way, give the sauce a quick taste and adjust with a tiny splash of soy sauce or brown sugar if it needs more punch. Cover the skillet loosely with foil to keep everything warm while you finish the last few steps.

Step 6

Heat your wok over medium-high until it’s shimmering hot, then pour in just enough oil to lightly coat the bottom—about 1 cup. Swirl the oil around to warm it evenly, testing with a wooden chopstick if you like; it’s ready when little bubbles cling to the stick within 30 seconds. Slide half the beef strips into the wok in a single layer so they sear instead of steam, letting them sizzle for about 90 seconds without stirring. Give the beef a quick toss, then flip and sear the other side another 30 seconds until the edges just start to turn a deep caramel color.

Step 7

Here’s the expanded version of Step 7 with the warmth, clarity, and detail you’re looking for: --- After the beef is seared and resting on paper towels, grab your slotted spoon and carefully transfer the browned pieces to a plate lined with paper towels. You’ll want to leave behind most of the oil in the wok—just tilt it slightly to let the excess drain out, then leave about a teaspoon behind to keep things moving smoothly. Set the wok back over medium-high heat for just 30 seconds to let that thin layer of oil shimmer. You’re not deep-frying here, just giving the pan a quick warm-up before the next step kicks in. The wok should be hot enough that a drop of water sizzles on contact when you test it. ---

Step 8

Here’s your expanded Step 8 with clear, step-by-step instructions: --- **Step 8:** Toss in the onions first, letting them sizzle right in the pan for about 30 seconds until they just start to soften. Then pile in the green onions and stir everything together—you’re aiming for the onions to glisten and brighten up the beef with their fresh color. Keep the heat steady so the green onions stay lively but don’t wilt into mush, about another 30 seconds should do it.

Step 9

Here’s your expanded Step 9 with all the details you need to nail it: --- Now that your beef is looking gorgeously caramelized, carefully scoop it back into the pan with the sauce. Toss everything together with a spatula so every piece gets coated in that glossy, savory glaze. Let it bubble away for about 45–60 seconds—just long enough for the sauce to thicken slightly and cling to the beef without turning gloopy. You’ll know it’s ready when the edges start to look just a shade darker and the beef looks juicy again.

Step 10

Here’s how you can expand Step 10 into clear, engaging cooking instructions: --- **Serve it up right.** Spoon your glossy, sticky jasmine rice onto a platter or individual plates, creating a soft bed for the beef. Nestle the crispy beef slices on top so every bite gets a little rice and a lot of flavor. Sprinkle fresh cilantro leaves over the top—just enough to add a pop of green and a bright herbal note.

My Tip

Slice your flank steak into ¼-inch pieces, then toss them gently with the cornstarch, egg white, salt, and sesame oil—just until each piece glistens. This little coat is your secret weapon for a silky, restaurant-worthy velvet texture that clings to every bite of sauce.

Leftovers

Keep leftover Mongolian beef in a shallow airtight container—it cools faster so the cornstarch coating stays crisp instead of turning soggy. Pop it in the fridge for up to 3 days. Reheat gently in a skillet over medium-low heat with a splash of water or sesame oil to revive the sauce without drying out the steak.

Make It Your Own

Swap the flank steak for **thinly sliced chicken thighs**—they stay juicy under the high heat and soak up the sauce like a dream. Keep everything else the same, and you’ll get that same glossy, sticky magic with even more tenderness.
