🥢 Easy Mongolian Beef Recipe

Prep Time: 15 minutes
Cook Time: 15 minutes
Total Time: 30 minutes
Servings: 4

Ingredients

For the Beef

• 1½ pounds flank steak, thinly sliced against the grain
• ⅓ cup cornstarch
• 3 tablespoons vegetable oil, divided
• ¼ teaspoon black pepper

For the Mongolian Beef Sauce

• ½ cup low-sodium soy sauce
• ½ cup water
• ⅓ cup packed brown sugar
• 4 garlic cloves, minced
• 1 tablespoon freshly grated ginger
• 1 tablespoon rice vinegar
• 1 teaspoon sesame oil
• ¼ teaspoon crushed red pepper flakes (optional)

For Serving

• 3 green onions, sliced
• 1 teaspoon sesame seeds (optional)
• Cooked white rice, brown rice, or noodles

 

👩‍🍳 How to Make Mongolian Beef

Step 1: Slice the Beef

Place the flank steak on a cutting board and slice it thinly against the grain.

This helps shorten the muscle fibers, making the beef more tender.

Lou Lou Girls Tip: Pop the steak in the freezer for about 15–20 minutes before slicing. Slightly firm beef is much easier to cut into thin, even strips.

And yes, this is one of those little tricks that makes you feel like a professional chef.

Apron optional.

Confidence required.

Step 2: Coat with Cornstarch

Place the sliced beef in a large bowl.

Add the cornstarch and black pepper.

Toss until the beef is evenly coated.

Let it rest for approximately 5 minutes while you prepare the sauce.

The cornstarch helps create a lightly crisp exterior and contributes to the sauce’s glossy finish.

Step 3: Whisk Together the Sauce

In a medium bowl, combine the soy sauce, water, brown sugar, minced garlic, grated ginger, rice vinegar, sesame oil, and optional red pepper flakes.

Whisk until the brown sugar begins to dissolve.

Set aside.

Go ahead and admire that sauce.

She’s about to do wonderful things.

Step 4: Sear the Beef

Heat 2 tablespoons of vegetable oil in a large skillet or wok over medium-high heat.

Add half the beef in a single layer.

Cook for approximately 1–2 minutes per side, until browned and cooked through.

Transfer to a plate.

Add the remaining tablespoon of oil as needed and cook the remaining beef.

Important: Don’t overcrowd the skillet!

We want beautiful golden edges, not beef having a crowded little steam bath.

Step 5: Make the Sauce

Reduce the heat to medium.

Pour the prepared sauce into the skillet.

Bring to a gentle simmer, stirring frequently.

Cook for 2–3 minutes, until the garlic and ginger are fragrant and the sauce begins to reduce.

Step 6: Bring Everything Together

Return the cooked beef and any accumulated juices to the skillet.

Toss until the beef is completely coated.

Simmer for another 1–2 minutes, until the sauce thickens slightly and becomes glossy.

If the sauce becomes too thick, add a tablespoon or two of water.

If you’d like it thicker, simmer briefly while stirring.

And just like that…

DINNER IS OFFICIALLY SHOWING OFF!

Step 7: Serve and Enjoy

Spoon the Mongolian Beef over hot rice or noodles.

Sprinkle with sliced green onions and sesame seeds.

Serve immediately.

Then prepare for the compliments.

You’re welcome.

 

🔥 Cooking Tips for Restaurant-Style Mongolian Beef

1. Always Slice Against the Grain

This is one of the biggest secrets to tender beef.

Look for the direction of the muscle fibers and slice across them rather than parallel to them.

2. Use a Hot Skillet

A properly heated skillet helps the beef brown quickly without overcooking.

3. Cook in Batches

Overcrowding lowers the pan temperature and causes steaming instead of browning.

Give those beef strips a little personal space.

4. Fresh Ginger Makes a Difference

Fresh ginger gives the sauce a bright, aromatic flavor.

Ground ginger can work in a pinch, but fresh is especially delicious here.

5. Don’t Overcook the Beef

Thinly sliced flank steak cooks quickly.

Once browned and cooked through, remove it from the skillet until you’re ready to coat it in sauce.

6. Adjust the Sweetness

Prefer a less sweet sauce?

Reduce the brown sugar to ¼ cup.

Taste and adjust to your family’s preferences.

 

🍜 Delicious Mongolian Beef Variations

Spicy Mongolian Beef

Add extra crushed red pepper flakes or a spoonful of chili garlic sauce.

Perfect for anyone who believes dinner should come with a little attitude.

Mongolian Beef and Broccoli

Add 2 cups of steamed broccoli florets when you return the beef to the sauce.

It’s colorful, delicious, and a great way to add vegetables.

Mongolian Beef Noodles

Toss the finished beef and sauce with cooked lo mein noodles or spaghetti.

Because sometimes noodles just understand us.

Mongolian Chicken

Swap the flank steak for thinly sliced boneless, skinless chicken breast or thighs.

Cook the chicken thoroughly to 165°F.

Mongolian Beef Lettuce Wraps

Serve the beef in crisp lettuce leaves with shredded carrots and sliced green onions.

Fresh, crunchy, and perfect for a lighter meal.

Extra-Garlicky Mongolian Beef

Add another two cloves of garlic.

Garlic lovers, this one’s for you.

 

👧 Kid Tips: Getting the Whole Family Excited

Mongolian Beef is a great introduction to sweet-and-savory Asian-inspired flavors.

For younger eaters, leave out the red pepper flakes.

Cut the beef into smaller, bite-sized pieces.

Serve the sauce on the side if your children prefer less sauce.

You can also serve the beef with plain rice and steamed broccoli.

And here’s a little dinner trick:

Let your kids build their own rice bowls!

Set out bowls of rice, beef, vegetables, and toppings.

Everyone gets to create their perfect dinner.

Reader question: Do your kids prefer rice or noodles?

🛒 Grocery Hacks That Save Money

We love a fabulous dinner.

We love saving money even more.

Here are a few ways to make this recipe easier on your grocery budget.

Watch for flank steak sales. Buy extra when the price is good and freeze it in meal-sized portions.

Compare other beef cuts. Sirloin can work well when sliced thinly against the grain.

Buy larger bags of rice. Rice is an affordable pantry staple that works with countless meals.

Use store-brand soy sauce. Compare ingredients and sodium levels to find a good option.

Freeze fresh ginger. Store peeled ginger in the freezer and grate it as needed.

Keep cornstarch stocked. It’s inexpensive and useful for thickening sauces and coating proteins.

Stretch the meal with vegetables. Broccoli, carrots, and bell peppers add color and help create more servings.

And here’s another idea:

Double the sauce ingredients if you’re adding extra vegetables or noodles.

Because nobody wants a sad, dry rice bowl.

Nobody.
