Recipe
Mongolian Beef is a popular Asian-inspired dish known for its savory and slightly sweet flavors, combined with tender slices of beef.
This dish is quick to prepare and perfect for a weeknight dinner or a special occasion.
The key to achieving the perfect texture and flavor lies in properly preparing the beef and creating a well-balanced sauce.
With just a few simple ingredients, you can recreate this restaurant favorite at home.
The dish starts with thinly sliced flank steak, which is then coated in cornstarch to create a crispy exterior when cooked.
The beef is stir-fried until golden brown, and then it’s tossed in a flavorful sauce made from soy sauce, brown sugar, and fresh aromatics like ginger and garlic.
A touch of green onions adds a burst of freshness and color to the dish.
Serve this delicious Mongolian Beef over steamed rice for a complete meal.
To prepare Mongolian Beef, start by coating the flank steak slices with cornstarch and let them sit for about 10 minutes.
Heat the vegetable oil in a large skillet or wok over medium-high heat.
Add the steak in batches, cooking until each piece is crispy and browned, then remove from the skillet.
In the same skillet, sauté the minced ginger and garlic briefly until fragrant.
Next, pour in the soy sauce, water, and brown sugar, stirring until the sugar dissolves.
Return the cooked steak to the skillet and toss it in the sauce until well coated.
Add the green onions and cook for an additional minute.
Remove from heat and let the dish rest for 5 minutes before serving.
Garnish with sesame seeds if desired and enjoy hot.
For an even more tender result, consider marinating the steak slices in a tablespoon of soy sauce and a teaspoon of baking soda for 30 minutes before coating them with cornstarch.
This step helps to break down the meat fibers, resulting in a softer texture.
Additionally, make sure not to overcrowd the pan when frying the beef, as this can prevent the pieces from becoming crispy.
Feel free to adjust the sweetness and saltiness of the dish by modifying the sugar and soy sauce quantities to suit your taste preferences.
Cooking Steps
To start, coat the thinly sliced flank steak with cornstarch, ensuring even coverage, and let it rest for 10 minutes.
Heat the vegetable oil in your skillet over medium-high heat, and cook the steak in batches until it’s crispy and browned.
Next, sauté the minced ginger and garlic in the same skillet, then add soy sauce, water, and brown sugar, stirring until the sugar completely dissolves.
Step 1. Coat Steak With Cornstarch

Start by verifying your flank steak is thinly sliced, as this will help it cook more evenly and quickly.
Lay the slices out on a cutting board in a single layer.
Measure out 1/4 cup of cornstarch using a measuring cup.
Sprinkle the cornstarch evenly over the steak slices, confirming each piece is fully coated.
Use your hands to gently pat the cornstarch into the meat, creating a thin, even layer.
This coating helps lock in the juices and achieves a crispy texture when cooked.
Allow the coated steak to rest for 10 minutes.
This resting period confirms the cornstarch adheres properly to the meat, forming a protective barrier that enhances the steak’s final texture and flavor.
Step 2. Heat Oil in Skillet

While your steak rests, you’ll want to prepare the cooking surface by heating the vegetable oil.
Place your large skillet or wok over medium-high heat.
Pour in 1/3 cup of vegetable oil, making sure it evenly coats the bottom.
Allow the oil to heat until it shimmers; this indicates it’s reached the ideal temperature for frying.
You can test the readiness by carefully flicking a tiny drop of water into the oil. If it sizzles immediately, the oil is hot enough.
Maintaining consistent heat is vital, so adjust the burner if needed.
Avoid letting the oil smoke, as this indicates it’s too hot and could burn the steak.
Properly heated oil guarantees a crispy texture without absorbing excess grease.
Step 3. Cook Steak Until Crispy

You’ve prepped your skillet, and now it’s time to achieve that perfect crispy texture for your steak.
Begin by coating the thinly sliced flank steak pieces with cornstarch.
Allow them to rest for about 10 minutes; this step guarantees maximum crispiness.
With your oil heated to a shimmering state, use tongs to carefully add the steak slices in a single layer.
Avoid overcrowding to guarantee even browning.
Cook each side for about 2-3 minutes until golden brown and crispy.
Remove the steak and let it rest on a paper towel-lined plate to drain excess oil.
Step | Description |
---|---|
1 | Coat steak with cornstarch |
2 | Let rest for 10 minutes |
3 | Add steak to hot skillet |
4 | Cook each side 2-3 minutes |
5 | Drain on paper towel |
Step 4. Sauté Ginger and Garlic

As soon as the steak is set aside, focus on infusing your dish with aromatic flavors by sautéing ginger and garlic.
Begin by ensuring your skillet or wok retains medium-high heat from cooking the steak.
Add a tablespoon of minced fresh ginger and two cloves of minced garlic directly into the hot oil remaining in the pan.
Use a spatula to stir them consistently, ensuring even cooking and preventing burning.
You’re aiming for the ginger and garlic to become fragrant, which typically takes about 30 seconds to a minute.
Watch closely for the garlic to turn a light golden color, signaling it’s perfectly sautéed.
This step is essential for building the dish’s foundational flavors, so don’t rush the process.
Step 5. Dissolve Sugar in Soy Sauce
Pour the soy sauce and water into the skillet, embracing the sizzling sound as they meet the hot pan.
This step deglazes, capturing the flavors from sautéed ginger and garlic.
Immediately add the packed brown sugar, stirring continuously with a spatula.
Maintain a medium-high heat to guarantee the sugar dissolves efficiently, forming a glossy, cohesive sauce.
Watch closely as the sugar integrates, reducing any graininess.
Adjust your stirring speed to prevent any clumping or burning.
The mixture should thicken slightly, coating the back of the spatula.
Once the sugar is fully dissolved, the sauce will appear smooth and aromatic.
This balance of sweet and savory forms the backbone of your dish, ready to envelop the crispy beef in flavorful perfection.
Serving Tips
- Steamed Jasmine Rice: A classic pairing that helps soak up the savory sauce and balances the richness of the beef.
- Stir-fried Vegetables: Add some color and nutrition to your meal with a mix of bell peppers, broccoli, and snap peas.
- Egg Fried Rice: For a more indulgent side, serve with egg fried rice for additional flavor and texture.
- Cucumber Salad: A revitalizing cucumber salad with a light vinaigrette can provide a cool contrast to the warm, savory beef.
- Noodles: Toss some cooked noodles in sesame oil and soy sauce for a satisfying, slurpable side.
Reheating
Reheating:
Reheat Mongolian Beef in a skillet over medium heat until thoroughly warmed.
Add a splash of water or soy sauce to prevent drying out and to enhance the sauce’s consistency.
Final Thoughts
As you savor the flavorful Mongolian Beef, it’s clear that mastering this dish is both rewarding and achievable with some attention to detail.
Begin by ensuring your flank steak is thinly sliced for ideal tenderness. The cornstarch coating is essential—it creates a crispy exterior when fried.
Don’t overcrowd the pan; cook the beef in batches to maintain that crisp texture.
