This Mongolian beef recipe came into my life after a long Friday at work when I was craving Chinese takeout but didn’t want to spend the money or wait for delivery. I had flank steak in the fridge, soy sauce in the pantry, and about 25 minutes — and honestly what came out of that pan was better than anything I had ever ordered from a restaurant. The sauce is sticky, sweet, deeply savory, and absolutely addictive. My family now requests this almost every week, and I am more than happy to keep making it.
Mary’s tip: Freeze the beef for 20 minutes before slicing — it firms up just enough to get those perfect paper-thin slices that cook quickly and soak up all that incredible sauce.

How to Slice Beef for Mongolian Beef
Proper slicing is essential for tenderness.
- Choose flank steak or sirloin.

Slicing against the grain shortens muscle fibers, resulting in a more tender texture.

Place the sliced beef in a bowl and toss with cornstarch. Let it rest for 10 minutes to create a crispy coating when fried.
Step 3: Heat the Oil
Heat vegetable oil in a wok or skillet over medium-high heat.
Step 4: Cook the Beef
Add the beef in batches and fry for 2–3 minutes until crispy and browned. Remove and set aside.

In the same pan, add garlic and ginger. Stir-fry for about 30 seconds until fragrant.
Step 6: Add the Sauce
Pour the prepared sauce into the pan and simmer until it thickens slightly.
Step 7: Combine the Ingredients
Return the beef to the pan and toss to coat evenly in the sauce.
Step 8: Add Green Onions
Stir in the sliced green onions and cook for an additional minute.
Step 9: Serve
