What Ingredients You Will Need

This recipe uses straightforward ingredients that work together to make the sauce rich and the beef tender, with the green onions adding a fresh kick. Most of these you probably have on hand already!

Beef: 1 pound (450g) flank steak, thinly sliced against the grain (for tenderness)
Green Onions: 4-5 large stalks, sliced diagonally into 2-inch pieces (adds that signature fresh crunch)
Soy Sauce: ½ cup (120ml) low-sodium soy sauce (I prefer Kikkoman for balanced flavor)
Brown Sugar: ⅓ cup (65g), packed (provides that perfect caramelized sweetness)
Garlic: 3 cloves, minced (aromatic base for the sauce)
Ginger: 1 tablespoon fresh grated (adds warmth and a subtle zing)
Vegetable Oil: 2 tablespoons, for stir-frying (neutral oil works best)
Cornstarch: ¼ cup (30g), for dusting the beef (helps create that crispy, coated texture)
Water: ½ cup (120ml), to thin the sauce as needed
Optional: Red pepper flakes (a pinch for heat), sesame seeds for garnish

If you want a gluten-free option, swap the soy sauce with tamari or coconut aminos. Also, for a slightly healthier spin, I sometimes use coconut sugar instead of brown sugar—it still caramelizes nicely but with a different sweetness profile. For the beef, flank steak is my go-to because it’s affordable and tender when sliced thinly. Just make sure to slice it properly against the grain—that little trick makes all the difference!

Equipment Needed

Wok or Large Skillet: A wok is ideal for high-heat stir-frying, but a heavy-bottomed skillet works well too. I use my carbon steel wok because it heats evenly and develops a nice seasoning over time.
Bowl: For mixing the sauce ingredients.
Sharp Knife: Essential for slicing the beef thinly and cutting the green onions.
Cutting Board: A sturdy surface to prep your ingredients.
Tongs or Spatula: For stirring and tossing the beef in the wok.

If you don’t have a wok, don’t sweat it—just use your largest skillet. Non-stick is fine, but a stainless steel pan can give you a better sear on the beef. Also, keep your tools sharp; a dull knife makes slicing thin beef slices harder and more dangerous. I usually keep a small bench sharpener handy to maintain my knives.

Detailed Preparation Method

Prep the Beef: Slice 1 pound (450g) of flank steak thinly against the grain into ¼-inch (6mm) strips. Toss the beef slices in ¼ cup (30g) cornstarch until lightly coated. This helps create a crispy texture when cooked. Set aside for 10 minutes to let the coating stick.
Mix the Sauce: In a bowl, combine ½ cup (120ml) low-sodium soy sauce, ⅓ cup (65g) packed brown sugar, 3 minced garlic cloves, and 1 tablespoon grated fresh ginger. Stir until the sugar dissolves. Set aside.
Heat the Pan: Place your wok or large skillet over medium-high heat and add 2 tablespoons vegetable oil. Let it get hot but not smoking—about 1-2 minutes. You’ll know it’s ready when the oil shimmers.
Cook the Beef: Add the coated beef strips in a single layer (do this in batches if needed to avoid overcrowding). Stir-fry for about 2-3 minutes, until the beef is browned and slightly crispy on the edges but not fully cooked through. Remove the beef and set aside.
Make the Sauce: Lower the heat to medium. Pour the sauce mixture into the wok and bring it to a gentle boil. Let it simmer for 2-3 minutes, stirring constantly, until it thickens slightly. If the sauce gets too thick, add up to ½ cup (120ml) water to loosen it.
Combine Beef and Sauce: Return the beef to the wok, tossing it in the sauce to coat evenly. Cook for another 1-2 minutes until the beef is cooked through and the sauce clings to each piece.
Add Green Onions: Toss in 4-5 sliced green onions and cook for 30 seconds to 1 minute just to soften slightly while keeping their bright crunch.
Final Touches: Optional—sprinkle with toasted sesame seeds or a pinch of red pepper flakes for some heat. Remove from heat and serve immediately.

Quick tip: If your beef sticks to the pan, don’t scrape aggressively—let it loosen naturally as the sauce thickens. You want that little bit of caramelized goodness on the bottom! Also, slicing the beef thin and against the grain helps keep it tender, no matter how fast you cook it.

Cooking Tips & Techniques

One of the trickiest parts of Mongolian beef is getting that perfect sear without overcooking. I learned the hard way that overcrowding the pan steams the beef rather than browning it, so always cook in batches if necessary. Trust me, it’s worth the extra step.

Also, make sure your pan and oil are hot before adding the beef. This locks in the juices and creates that irresistible crust. Using cornstarch on the beef not only crisps the edges but also thickens the sauce naturally—two birds, one stone!

When making the sauce, stirring constantly helps prevent burning and keeps the sauce smooth. Adjust the sweetness or saltiness by tasting as it simmers—some soy sauces can be saltier, so a quick taste test saves you from surprises.

For timing, prep all ingredients first, then cook fast. This recipe moves quickly once the heat is on, so mise en place (everything in its place) is key. I usually slice the beef, mix the sauce, and chop green onions before turning on the stove.

Variations & Adaptations

Spicy Twist: Add ½ teaspoon chili paste or a few dashes of Sriracha to the sauce for an extra kick.
Gluten-Free Version: Use tamari or coconut aminos instead of soy sauce, and make sure your cornstarch is gluten-free.
Vegetarian Swap: Substitute beef with thick slices of king oyster mushrooms or tofu for a meaty texture without meat.
Alternate Veggies: Add bell peppers, snap peas, or shredded carrots for color and crunch.

Personally, I once tried swapping brown sugar for honey—it gave a different sweetness and slightly thinner sauce but was still delicious. If you’re experimenting with cooking methods, try cooking the beef in a cast iron skillet for a deeper sear or under the broiler for a quick finish.

Serving & Storage Suggestions

This Mongolian beef shines best served hot straight from the pan over steamed white or jasmine rice. The fluffy rice soaks up the sticky sauce perfectly. I also like it with simple steamed broccoli or snap peas for a balanced meal.

Store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, warm gently in a skillet over medium heat, adding a splash of water to loosen the sauce if it thickened too much. Avoid microwaving if possible to keep the beef tender and sauce glossy.

You know that flavors mellow and deepen after resting overnight, so if you can, make this a day ahead for an even richer taste. Just reheat gently and add fresh green onions on top before serving for that fresh pop.
