What Cut of Beef Should I Use?

The best cut for Mongolian Beef is flank steak because it’s lean, tender, and cooks quickly. However, you can also use sirloin or skirt steak if that’s what you have on hand. The key is slicing the beef thinly against the grain to ensure it stays tender and soaks up all that incredible sauce. If you want extra tenderness, a quick marinade in a bit of soy sauce and cornstarch does wonders.

How To Make the Mongolian Beef Easy Flavor-Packed Stir Fry

Step 1: Prep the Beef

Slice the flank steak thinly against the grain. Toss the slices in cornstarch and let them sit for 10 minutes—this helps the beef crisp up beautifully during cooking.

Step 2: Make the Sauce

In a bowl, whisk together soy sauce, brown sugar, minced garlic, grated ginger, and water. Set aside.

Step 3: Cook the Beef

Heat vegetable oil in a large skillet or wok over medium-high heat. Add the beef in batches, searing each side until browned and crispy. Remove and set aside.

Step 4: Simmer the Sauce

Pour the prepared sauce into the same skillet. Let it simmer for 2–3 minutes until slightly thickened.

Step 5: Combine and Finish

Add the seared beef back into the skillet, tossing to coat it in the sauce. Cook for another 2–3 minutes so everything melds together.

Step 6: Garnish and Serve

Top with chopped green onions and sesame seeds. Serve hot over steamed rice or noodles.
