Step-by-Step Instructions

Follow these detailed instructions to achieve perfectly tender beef with crispy edges and a glossy, flavorful sauce. Each step builds on the previous one to ensure success, even if you’re new to stir-frying. Take your time with the prep work, and the actual cooking will be quick and straightforward.

1. Prepare and Slice the Beef

Place the flank steak in the freezer for 20-30 minutes to firm up, making it much easier to slice thinly and evenly
Remove the partially frozen beef from the freezer and place it on a cutting board
Identify the direction of the muscle fibers (the grain) running through the meat
Using a sharp knife, slice the beef across the grain (perpendicular to the fibers) into strips about 1/4-inch (6mm) thick
Cut each strip into 2-3 inch (5-7cm) pieces for bite-sized portions
Pat the beef slices dry with paper towels to remove excess moisture, which helps achieve better browning

2. Coat the Beef with Cornstarch

Add the sliced beef to a large mixing bowl or gallon-sized ziplock bag
Sprinkle the cornstarch evenly over the beef pieces
Toss the beef thoroughly to coat each piece completely with cornstarch, ensuring no dry spots remain
Shake off any excess cornstarch so you have just a light, even coating on each piece
Let the coated beef sit for 5 minutes while you prepare the sauce, allowing the cornstarch to adhere properly

3. Make the Sauce

In a small bowl, whisk together the soy sauce, brown sugar, and water until the sugar dissolves completely
Continue stirring until no sugar granules remain and the mixture is smooth
Add the minced ginger and half of the minced garlic to the sauce mixture and stir to combine
Set the prepared sauce aside, keeping it within easy reach for when you need it during cooking

4. Sear the Beef

Heat 2 tablespoons of vegetable oil in your large skillet or wok over medium-high heat
Wait until the oil is shimmering and almost smoking, indicating it’s hot enough for a good sear
Working in batches to avoid overcrowding (overcrowding creates steam instead of a sear), add about half the beef in a single layer
Let the beef sit undisturbed for 1-2 minutes until the bottom develops a golden-brown, crispy crust
Flip each piece using tongs and cook for another 1 minute on the second side
Transfer the seared beef to a clean plate and repeat the process with the remaining beef, adding a bit more oil if needed
Once all beef is seared, set it aside while you finish the sauce

5. Cook the Aromatics and Sauce

Reduce the heat to medium and add the remaining 1 tablespoon of vegetable oil to the same skillet
Add the remaining minced garlic and the white parts of the sliced green onions
Stir constantly for 30-40 seconds until fragrant but not browned, as burnt garlic tastes bitter
Pour the prepared sauce into the skillet, scraping up any browned bits from the bottom of the pan with a wooden spoon
Add the sesame oil and red pepper flakes if using
Bring the sauce to a vigorous boil, stirring occasionally
Let it boil for 2-3 minutes until it reduces slightly and thickens to a glossy, syrupy consistency

6. Combine and Finish

Return all the seared beef to the skillet with the thickened sauce
Toss the beef gently to coat each piece evenly with the sauce
Cook for 1-2 minutes, stirring constantly, until the beef is heated through and the sauce clings to each piece
Remove the skillet from heat immediately to prevent overcooking the beef
Stir in most of the green parts of the sliced green onions, reserving a small handful for garnish
Transfer the Mongolian beef to a serving platter or individual plates
Garnish with the reserved green onion slices for a fresh pop of color and mild onion flavor

Tips for Success

These tips will help you achieve restaurant-quality results every single time you make this recipe. Pay special attention to the beef preparation and cooking temperature, as these factors make the biggest difference in the final dish.

Freeze the beef briefly: Putting the flank steak in the freezer for 20-30 minutes makes it much easier to slice thinly and evenly, resulting in more tender pieces that cook uniformly
Slice against the grain: Always cut perpendicular to the muscle fibers to shorten them, which makes each bite significantly more tender and easier to chew
Don’t skip the cornstarch coating: This step creates a protective barrier that keeps the beef tender while creating crispy edges, and it helps the sauce cling to each piece beautifully
Use high heat: A hot pan is essential for achieving that crispy sear on the beef without overcooking the interior, so make sure your oil is shimmering before adding the beef
Cook in batches: Overcrowding the pan lowers the temperature and causes steaming instead of searing, resulting in gray, tough beef instead of caramelized pieces
Don’t overcook: Flank steak becomes tough when overcooked, so aim for medium-rare to medium for the most tender results
Adjust sweetness: If you prefer less sweet, reduce the brown sugar to 1/3 cup and add an extra tablespoon of soy sauce for more savory depth

Variations to Try

Once you’ve mastered the basic recipe, these variations let you customize the dish to your preferences or dietary needs. Each option brings something unique while maintaining the essential character of Mongolian beef.

Spicier version: Double the red pepper flakes or add 1-2 teaspoons of sriracha or sambal oelek to the sauce for serious heat
Extra vegetables: Stir in sliced bell peppers, snap peas, or sliced onions along with the white parts of the green onions for more color and nutrition
Mongolian chicken: Substitute boneless, skinless chicken thighs for the beef, cutting them into bite-sized pieces and following the same cooking method
Lower sodium: Use reduced-sodium soy sauce or coconut aminos, and reduce the amount to 1/3 cup, balancing with extra ginger and garlic for flavor
Less sweet: Cut the brown sugar in half and add a tablespoon of hoisin sauce for complexity without excessive sweetness
Crispy beef variation: After coating with cornstarch, deep fry the beef pieces in oil heated to 350°F (175°C) until golden and crispy, then toss with the sauce
Add sesame seeds: Sprinkle toasted sesame seeds over the finished dish for extra nutty flavor and visual appeal

Storage and Reheating

Proper storage keeps your leftover Mongolian beef tasting fresh and delicious for several days. The sauce may thicken as it cools, but gentle reheating brings back the perfect consistency.

Refrigerator storage: Transfer cooled Mongolian beef to an airtight container and refrigerate for up to 4 days, storing any rice separately to prevent sogginess
Freezer storage: While fresh is best, you can freeze Mongolian beef in a freezer-safe container for up to 3 months, though the texture of the beef may change slightly
Reheating on stovetop: Add the beef to a skillet over medium heat with a splash of water or broth to loosen the sauce, stirring gently until heated through
Reheating in microwave: Place in a microwave-safe dish, cover loosely, and heat in 1-minute intervals, stirring between each interval until hot throughout
Prevent overcooking: Reheat just until warmed through to avoid making the beef tough, as overcooking is the enemy of tender meat
Best practice: Let refrigerated Mongolian beef come to room temperature for 10-15 minutes before reheating for more even warming

Frequently Asked Questions

1. Can I use a different cut of beef for this recipe?

Yes, you can substitute sirloin steak or ribeye, though flank steak is ideal because it becomes incredibly tender when sliced thin and cooked quickly. If using a more expensive cut like ribeye, you’ll get excellent results but at a higher cost.

2. Why is my sauce too thin or too thick?

The sauce should thicken as it boils and reduces. If it’s too thin, let it simmer for an extra 1-2 minutes, or whisk in a slurry of 1 teaspoon cornstarch mixed with 1 tablespoon water. If too thick, simply add water one tablespoon at a time until you reach the desired consistency.

3. Can I make this recipe ahead of time?

You can slice and coat the beef up to a day ahead, storing it covered in the refrigerator, and mix the sauce ingredients in advance. However, the actual cooking should be done just before serving for the best texture and flavor.

4. Is Mongolian beef actually from Mongolia?

No, despite its name, Mongolian beef is an American-Chinese dish created in Chinese-American restaurants. Traditional Mongolian cuisine typically features boiled or grilled meats rather than stir-fries like this one.

5. How do I prevent the beef from becoming tough?

The key is slicing thin against the grain, not overcooking the beef (aim for medium-rare to medium), and using high heat for quick searing. The cornstarch coating also helps protect the beef and keep it tender during cooking.
