Mongolian Beef Recipe

Intro: That First Sizzle in the Pan

There’s something about the smell of seared beef hitting a hot pan that makes me instantly hungry. I still remember the first time I made this Mongolian Beef Recipe at home. I had just come back from a long day in the kitchen, craving something bold, saucy, and deeply comforting — but I didn’t want takeout. I wanted that glossy, caramelized beef with the sweet-savory sauce clinging to every bite… made in my own skillet.

As the flank steak sizzled and the garlic met the heat, the aroma shifted from sharp to rich and savory in seconds. When the soy sauce and brown sugar melted together into a dark, bubbling glaze, I knew this Mongolian Beef Recipe was going to become one of my weeknight staples.

If you’ve ever ordered Mongolian beef at a restaurant and wondered if you could recreate that same tender texture and glossy sauce at home — I promise you can. And honestly? Homemade Mongolian Beef Recipe tastes fresher, richer, and even more satisfying.

Let me show you how I make it in my kitchen.

What is Mongolian Beef Recipe?

Despite the name, Mongolian Beef isn’t actually traditional Mongolian cuisine. It’s a beloved Chinese-American dish known for its tender slices of beef coated in a glossy, slightly sweet soy-based sauce and finished with fresh green onions.

What makes this Mongolian Beef Recipe so special is the balance:

• Savory soy sauce
• Sweet brown sugar
• Aromatic garlic and ginger
• Tender, velvety beef
• A subtle heat from red pepper flakes

The sauce reduces into a thick glaze that clings beautifully to thinly sliced flank steak. Each bite is juicy, slightly sticky, savory-sweet, and deeply comforting.

The key is high heat, quick cooking, and properly slicing the beef against the grain so it stays tender.

Why You’ll Love This Homemade Mongolian Beef Recipe

• Ready in under 30 minutes
• Better than takeout
• Made with simple pantry ingredients
• Perfect over rice or noodles
• Customizable spice level
• That irresistible glossy sauce

As a chef, I adore recipes that feel restaurant-worthy but are secretly simple. This easy Mongolian Beef Recipe checks every box.

Equipment You’ll Need

• Large skillet or wok
• Sharp chef’s knife
• Cutting board
• Mixing bowls
• Tongs or spatula
• Measuring cups and spoons

A heavy-bottomed skillet works beautifully if you don’t have a wok. The goal is high heat and good surface contact for that caramelization.

Ingredients

• 1 pound flank steak, thinly sliced against the grain
• 1/4 cup cornstarch
• 2 tablespoons vegetable oil (for frying)
• 3 cloves garlic, minced
• 1 tablespoon fresh ginger, grated
• 1/2 cup low-sodium soy sauce
• 1/2 cup brown sugar (light or dark)
• 1/4 cup water
• 1/2 teaspoon red pepper flakes (optional)
• 4 green onions, sliced into 1-inch pieces
• Cooked white rice, for serving

Step-by-Step Instructions

Step 1: Slice the Beef Properly

Place your flank steak in the freezer for about 20 minutes to firm up slightly. This makes it easier to slice thinly. Cut against the grain into thin strips. Proper slicing ensures tender, melt-in-your-mouth beef.

Step 2: Coat with Cornstarch

Toss the sliced beef with cornstarch until evenly coated. Let it sit for about 10 minutes. This coating helps create that light crust and thickens the sauce later.

Step 3: Sear Until Golden

Heat oil in a large skillet over medium-high heat. Add the beef in a single layer, cooking in batches if necessary. Sear for 2–3 minutes per side until browned and slightly crispy at the edges.

You should hear that satisfying sizzle. That’s flavor building.

Remove the beef and set aside.

Step 4: Build the Sauce

In the same pan, reduce heat slightly. Add garlic and ginger. Sauté for about 30 seconds until fragrant — you’ll smell that warm, spicy aroma immediately.

Add soy sauce, brown sugar, water, and red pepper flakes. Stir and bring to a gentle simmer. Watch as the sugar dissolves and the sauce begins to thicken slightly.

Step 5: Combine and Glaze

Return the beef to the pan and toss to coat. Let everything simmer for 2–3 minutes until the sauce thickens into a glossy glaze that clings to the meat.

Add green onions and cook for another minute.

The sauce should look shiny and slightly sticky, not watery.

Step 6: Serve Immediately

Serve hot over steamed white rice. Spoon extra sauce over the top — trust me, you’ll want every drop.

My Chef Tips for Perfect Mongolian Beef Recipe

After making this countless times, here’s what I’ve learned:

• Always slice against the grain for tenderness
• Don’t overcrowd the pan — it causes steaming instead of browning
• Use high heat for quick caramelization
• Taste your sauce before adding the beef back
• Add a splash of water if the glaze thickens too quickly

This classic Mongolian Beef Recipe is all about balance and timing.

What to Serve with Mongolian Beef

This dish pairs beautifully with:

• Steamed jasmine rice
• Fried rice
• Garlic noodles
• Stir-fried broccoli
• Bok choy
• Cucumber salad for freshness

I personally love serving it with fluffy white rice and lightly steamed broccoli. The bright green next to the deep caramel sauce is just beautiful on the plate.

Storage and Reheating Tips

If you somehow have leftovers (rare in my house):

• Store in an airtight container for up to 3 days
• Reheat gently in a skillet with a splash of water
• Avoid microwaving too long — it can toughen the beef

The sauce may thicken in the fridge, but loosens beautifully when reheated.

Variations You Can Try

I love playing with this Mongolian Beef Recipe depending on my mood.

• Add sliced bell peppers for color
• Stir in mushrooms for earthiness
• Swap flank steak for sirloin
• Add a drizzle of sesame oil at the end
• Increase red pepper flakes for more heat

Cooking should feel creative, not rigid.

FAQs

Can I make Mongolian Beef Recipe ahead of time?

It’s best fresh, but you can prepare the sauce ahead and slice the beef in advance for quicker cooking.

What cut of beef works best?

Flank steak is ideal because it’s flavorful and tender when sliced correctly. Sirloin also works well.

Is Mongolian Beef spicy?

Traditionally, it’s more sweet and savory than spicy. You can adjust heat with red pepper flakes.

Yes! Use gluten-free soy sauce or tamari.

Why is my beef tough?
