🍜 What Is Mongolian Beef?
Despite its name, Mongolian beef isn’t from Mongolia. It’s actually a beloved dish from Chinese-American cuisine — made famous by restaurants like P.F. Chang’s. The key to this dish is its sweet and savory sauce, made with soy sauce, brown sugar, garlic, and ginger, which caramelizes beautifully as it coats the beef.
It’s a balance of rich umami, mild sweetness, and a touch of spice — a combination that makes this meal so irresistible!
So if you’re looking for a quick, comforting stir-fry, this easy Mongolian beef recipe is just what you need.
🥩 Ingredients You’ll Need
You only need a few pantry staples to bring this dish together.
For the Beef:
1 lb (450 g) flank steak or sirloin, thinly sliced against the grain
2 tablespoons cornstarch
2 tablespoons vegetable oil
For the Sauce:
¾ cup soy sauce (low-sodium recommended)
½ cup brown sugar, packed
¼ cup water
1 tablespoon minced garlic (about 3 cloves)
1 tablespoon fresh grated ginger
1–2 teaspoons chili flakes or sriracha (optional for heat)
For Garnish:
3–4 green onions, chopped
Sesame seeds (optional)
🍚 Serve with: Steamed white rice, jasmine rice, or noodles for a full meal.
🔪 Step-by-Step: Easy Mongolian Beef Recipe
Step 1: Prepare the Beef
Slice your beef thinly against the grain — this keeps it tender. Toss the slices with cornstarch until evenly coated. Let it rest for 10 minutes while you prepare the sauce.
💡 Tip: Freeze your beef for 15 minutes before slicing to make cutting easier and cleaner.
Step 2: Make the Sauce
In a small bowl, whisk together soy sauce, brown sugar, water, garlic, ginger, and chili flakes. Set aside — you’ll add this once the beef is browned.
Step 3: Cook the Beef
Heat oil in a large skillet or wok over medium-high heat. Add beef slices in batches (don’t overcrowd the pan). Cook 1–2 minutes per side until browned and slightly crispy at the edges. Remove from pan and set aside.
Step 4: Combine Everything
In the same pan, pour in the sauce mixture. Bring it to a gentle simmer for about 2 minutes until it starts to thicken. Add the cooked beef back to the pan, stirring to coat every piece in the glossy sauce.
Let it cook for another 2–3 minutes until the sauce clings perfectly to the beef.
Step 5: Garnish and Serve
Turn off the heat, toss in chopped green onions, and sprinkle with sesame seeds if desired. Serve hot over rice or noodles — and enjoy the perfect balance of sweet, salty, and savory goodness!

🔥 Tips for Perfect Mongolian Beef Every Time
Slice thinly: The thinner the beef, the more tender and flavorful it becomes.
Use high heat: A hot pan sears the beef quickly and locks in juices.
Don’t skip the cornstarch: It gives the beef that crispy edge and helps the sauce cling.
Adjust sweetness: Like it less sweet? Reduce the brown sugar to ⅓ cup.
Thicken the sauce: Simmer a little longer if you want a thicker glaze.

Store cooled Mongolian beef in an airtight container in the fridge for up to 3–4 days.
