Ingredient Spotlight

Flank Steak

Flank steak is a fantastic choice for this mongolian beef recipe because it becomes incredibly tender when sliced thinly against the grain. It’s also a good source of protein, iron, and vitamin B12.

Ginger

Fresh ginger adds warmth and depth to the sauce while providing natural antioxidants that contribute to its distinctive flavor.

How to Make Mongolian Beef Recipe

Step 1: Prepare the Beef

Place the thinly sliced flank steak in a bowl and sprinkle the cornstarch evenly over the meat.

Toss until every piece is lightly coated. Let the beef sit for about 10 minutes. This coating helps create the signature texture while also thickening the sauce later.

Step 2: Make the Sauce

In a medium bowl, whisk together:

Soy sauce
Brown sugar
Water
Hoisin sauce
Garlic
Ginger
Sesame oil

Continue whisking until the sugar dissolves completely.

Step 3: Cook the Beef

Heat the vegetable oil in a large skillet or wok over medium-high heat.

Once the oil is hot, add the beef in a single layer. Avoid overcrowding the pan. Cook in batches if necessary.

Sear the beef for 2 to 3 minutes per side until lightly browned and crispy around the edges.

Transfer the cooked beef to a plate.

Step 4: Cook the Aromatics

If needed, add a small splash of oil to the skillet.

Add the garlic and ginger and cook for about 30 seconds until fragrant. Be careful not to burn them, as they can become bitter.

Step 5: Add the Sauce

Pour the prepared sauce into the skillet.

Bring it to a gentle simmer and cook for 2 to 3 minutes, stirring occasionally.

The sauce will begin to thicken naturally.

Step 6: Return the Beef

Add the cooked beef back into the skillet.

Toss everything together so the sauce coats every piece evenly.

Cook for another 2 minutes until the beef is heated through and the sauce reaches a glossy consistency.

Step 7: Add Green Onions

Stir in the sliced green onions.

Cook for 30 to 60 seconds, just until slightly softened while still retaining some freshness and crunch.

Step 8: Serve

Transfer the beef to a serving dish.

Sprinkle with sesame seeds if desired and serve immediately over steamed rice or noodles.

Common Mistakes to Avoid

Even a simple mongolian beef recipe can go wrong if a few important details are overlooked.

Slicing the Beef Too Thick

Thin slices cook quickly and absorb more flavor. Thick pieces may become chewy.

Skipping the Cornstarch

The cornstarch coating creates the classic texture and helps the sauce cling to the meat.

Overcrowding the Pan

Too much beef at once causes steaming rather than searing.

Burning the Garlic

Garlic cooks quickly. Burnt garlic can give the entire dish a bitter taste.

Overcooking the Beef

Beef continues cooking slightly after being removed from heat. Avoid leaving it in the pan too long.

Using Too Much Soy Sauce

An excess amount can make the dish overly salty and overpower the other flavors.

Not Tasting the Sauce

Always taste and adjust sweetness, saltiness, or spice levels before finishing the dish.
