Best Mongolian Beef Recipe – Tender & Flavorful

There’s something magical about the sizzle of beef hitting a hot pan, the sweet and savory aroma of garlic and ginger filling the kitchen, and the promise of a dish that’s both comforting and exciting. That’s exactly what this Mongolian Beef recipe brings to the table—tender slices of beef coated in a glossy, umami-rich sauce that’s just begging to be spooned over a steaming bowl of rice. It’s the kind of meal that feels like a warm hug, yet fancy enough to impress guests. And the best part? It comes together faster than takeout!

Ingredients You’ll Need

Before we dive into the cooking, let’s gather our ingredients. Trust me, every one of these plays a key role in creating that perfect balance of flavors:

• 1 lb flank steak or sirloin – Thinly sliced against the grain for maximum tenderness. Flank steak is my go-to, but sirloin works beautifully too.
• ¼ cup cornstarch – The secret to that crispy exterior while keeping the inside juicy.
• 3 cloves garlic – Minced. Because what’s a stir-fry without garlic?
• 1 tbsp fresh ginger – Grated. It adds that warm, zesty kick.
• ½ cup low-sodium soy sauce – A must for depth of flavor. If you only have regular soy sauce, just reduce the salt elsewhere.
• ½ cup brown sugar – For that irresistible caramelized sweetness.
• ¼ cup water – To balance the sauce.
• 2 tbsp vegetable oil – For frying. A high smoke point is key here.
• 3-4 green onions – Sliced into ribbons for a fresh finish.

Step-by-Step Instructions

Now, let’s bring this dish to life! Follow these steps, and you’ll have restaurant-quality Mongolian Beef in no time.

1. Prep the Beef

Slice your beef against the grain into thin strips—this ensures every bite is melt-in-your-mouth tender. Toss the slices in cornstarch until evenly coated, then shake off any excess. Let it sit for 5 minutes while you prep the sauce.

2. Make the Sauce

In a small bowl, whisk together the soy sauce, brown sugar, and water until the sugar dissolves. This simple trio creates magic when it hits the pan, so don’t skip the whisking!

3. Sear the Beef

Heat the oil in a large skillet or wok over medium-high heat. Working in batches (to avoid crowding the pan), fry the beef until golden and crispy, about 2 minutes per side. Transfer to a plate and set aside.

4. Bring It All Together

In the same pan, add the garlic and ginger, stirring for just 20 seconds until fragrant—be careful not to burn them! Pour in the sauce and let it simmer for 2-3 minutes until slightly thickened. Return the beef to the pan, tossing to coat evenly. Finish with a generous sprinkle of green onions.

And just like that, you’ve created a dish that’s bursting with flavor and ready to be devoured. But wait—there’s more! Let’s talk about how to make it your own and what to serve alongside it.

Pro Tips, Variations, and Substitutions

Making the perfect Mongolian Beef is all about balancing flavors and textures. Here are some expert tips and variations to help you customize this dish to your liking:

• For extra tenderness: Freeze the beef for 30 minutes before slicing—it makes cutting thin strips much easier!
• Gluten-free option: Swap soy sauce with tamari or coconut aminos for a gluten-free version.
• Spice it up: Add a teaspoon of chili flakes or a drizzle of sriracha for a spicy kick.
• Vegetarian twist: Substitute beef with portobello mushrooms or tofu for a plant-based alternative.
• Sweetness adjustment: If you prefer less sweetness, reduce the brown sugar by half or use honey as a substitute.

What to Serve with Mongolian Beef

This dish pairs beautifully with a variety of sides to create a complete, satisfying meal. Here are some of our favorites:

• Steamed jasmine rice: The classic choice—fluffy rice soaks up the delicious sauce.
• Stir-fried vegetables: Bok choy, bell peppers, or snap peas add a fresh crunch.
• Noodles: Toss with lo mein or rice noodles for a heartier meal.
• Green onion garnish: A sprinkle of fresh green onions adds brightness and color.

Storage and Reheating Tips

Mongolian Beef is just as tasty the next day! Here’s how to store and reheat it properly:

• Refrigeration: Store leftovers in an airtight container for up to 3 days.
• Freezing: Freeze in a sealed container for up to 2 months. Thaw overnight in the fridge before reheating.
• Reheating: Warm in a skillet over medium heat with a splash of water to revive the sauce. Avoid microwaving, as it can make the beef tough.

Frequently Asked Questions

Can I use a different cut of beef?
Yes! While flank steak is ideal, you can also use sirloin or ribeye. Just ensure it’s sliced thinly against the grain for tenderness.

Why is my sauce too thin?
If your sauce isn’t thickening, let it simmer a bit longer or add a cornstarch slurry (1 tsp cornstarch + 1 tbsp water) and stir until thickened.

Can I make this dish ahead of time?
Absolutely! Prepare the sauce and slice the beef in advance, then cook just before serving for the best texture.

Is Mongolian Beef the same as beef and broccoli?
No—while both are Chinese-American dishes, Mongolian Beef features a sweeter, stickier sauce and doesn’t include broccoli (though you can certainly add it!).
