Step-by-Step Instructions
Step 1: Prepare the Beef
Slice your flank steak into thin strips, approximately ¼-inch thick, cutting against the grain. This crucial technique shortens the muscle fibers, ensuring tender bites rather than chewy pieces. Place the sliced beef in a large bowl and toss with cornstarch until each piece is evenly coated. The cornstarch creates a protective barrier that seals in juices while developing a slightly crispy exterior during cooking.
Step 2: Make the Sauce
In a medium bowl, whisk together soy sauce, water, brown sugar, minced ginger, minced garlic, and red pepper flakes (if using). Stir vigorously until the brown sugar dissolves completely. This savory-sweet sauce embodies the signature flavors of authentic Mongolian beef, with the ginger and garlic providing aromatic depth that elevates the entire dish.
Step 3: Sear the Beef
Heat 2 tablespoons of vegetable oil in a large skillet or wok over medium-high heat until shimmering but not smoking. Working in batches to avoid overcrowding (which causes steaming rather than searing), add the cornstarch-coated beef in a single layer. Cook for 2-3 minutes per side until golden brown and crispy. Remove to a plate and repeat with remaining beef, adding more oil if needed. This high-heat searing locks in flavor and creates textural contrast.
Step 4: Combine and Simmer
Reduce heat to medium and add the prepared sauce to the same skillet, scraping up any flavorful brown bits from the bottom. Bring to a gentle simmer and cook for 3-4 minutes, stirring occasionally, until the sauce thickens and reduces by about one-third. The sauce should coat the back of a spoon with a glossy sheen.
Step 5: Finish the Dish
Return the seared beef to the skillet along with the green onions. Toss everything together for 1-2 minutes until the beef is heated through and completely coated in the luscious sauce. The green onions should remain slightly crisp, adding fresh flavor and color contrast.
Step 6: Serve and Garnish
Transfer your quick stir fry beef to a serving platter and sprinkle with toasted sesame seeds. Serve immediately over fluffy steamed rice or noodles to soak up every drop of that incredible sauce.

Common Mistakes to Avoid
Ensure perfect results every time by sidestepping these frequent pitfalls:
1. Cutting with the grain: Slicing beef parallel to the muscle fibers results in tough, chewy meat. Always cut perpendicular to the grain for maximum tenderness.
2. Overcrowding the pan: Adding too much beef at once drops the pan temperature, causing steaming instead of searing. Cook in batches for proper caramelization.
3. Skipping the cornstarch coating: This step is essential for achieving that signature texture. The coating creates a protective barrier and helps the sauce adhere.
4. Overcooking the beef: Since you'll return the beef to the sauce, initial cooking should be just until browned. Overcooking creates dry, tough meat.
5. Using cold ingredients: Room temperature beef sears better than cold meat straight from the refrigerator. Let it sit for 10 minutes before cooking.
6. Not reducing the sauce: The sauce needs time to thicken and concentrate flavors. Rushing this step results in a watery, less flavorful dish.
7. Low heat cooking: Mongolian beef requires high heat for proper searing and caramelization. Medium heat won't develop the same depth of flavor.
Storing Tips for the Recipe
Maximize freshness and flavor with these storage guidelines:

FAQs
Q: Can I use a different cut of beef for this recipe?
A: Absolutely! While flank steak is traditional, sirloin, ribeye, or skirt steak work beautifully. Choose cuts with good marbling for maximum tenderness. Avoid stew meat or chuck roast, as these tougher cuts require longer cooking times.
Q: Is Mongolian beef actually from Mongolia?
A: Despite the name, Mongolian beef is actually a Chinese-American creation developed in Taiwan and popularized in American Chinese restaurants. It's not traditionally eaten in Mongolia.
Q: Can I make this recipe gluten-free?
A: Yes! Simply substitute tamari or coconut aminos for regular soy sauce, and ensure your cornstarch is certified gluten-free. All other ingredients are naturally gluten-free.
Q: How can I make this spicier?
A: Increase the red pepper flakes to 1 teaspoon, add fresh sliced Thai chilies with the green onions, or drizzle with sriracha or chili oil before serving. You can also add a tablespoon of chili garlic sauce to the sauce mixture.
Q: Why is my sauce too thin?
A: The sauce thickens as it simmers due to the sugar content and residual cornstarch from the beef. If still thin, mix 1 teaspoon cornstarch with 1 tablespoon cold water and stir into the simmering sauce. Cook for 1 additional minute until thickened.
Q: Can I prepare this in advance for meal prep?
A: Yes! This 25 minute beef recipe is excellent for meal prep. Cook the complete dish, cool completely, and portion into containers with rice. It reheats wonderfully and the flavors continue to develop, making it even more delicious the next day.
Q: What's the best way to slice beef thinly?
A: Place the beef in the freezer for 30-45 minutes until firm but not frozen. This makes slicing much easier and more precise. Always use a sharp knife and cut against the grain in smooth, confident strokes.
Q: Can I add vegetables to this recipe?
A: Definitely! Broccoli, snap peas, bell peppers, and mushrooms all complement the flavors beautifully. Add heartier vegetables with the sauce, and quick-cooking vegetables with the green onions at the end.
