1-First Step: Prepare the Beef Begin by slicing 1 pound of flank steak into thin ¼-inch pieces, cutting against the grain for tenderness. Partially freeze the beef for 20 minutes first to make slicing easier and more precise. Toss the slices with ⅓ cup cornstarch, shaking off any excess, and set them aside to rest while you move on.

2-Second Step: Cook the Aromatics Heat 2 teaspoons of vegetable oil in a skillet over medium-low heat. Add ½ teaspoon of minced fresh ginger and 4 cloves of finely minced garlic, cooking them until fragrant, which takes about 1 minute. This step builds a flavorful base for the sauce, drawing out the garlic and ginger’s natural aromas.

3-Third Step: Make the Sauce Stir in ½ cup low-sodium soy sauce, ¼ cup water, and ½ cup packed brown sugar into the skillet. Bring the mixture to a boil, then simmer for 3-5 minutes until it thickens slightly. Once ready, transfer the sauce to a bowl and set it aside, giving you a sweet-savory coating for the beef.

4-Fourth Step: Sear the Beef In the same skillet or a wok, heat 1 tablespoon of the remaining vegetable oil over medium-high heat. Cook the beef in small batches for about 2 minutes each, just until it browns but doesn’t cook through completely. This prevents steaming and ensures a nice sear on each piece.

5-Fifth Step: Combine and Finish Return all the beef to the skillet with the reserved sauce and heat over medium until the mixture is hot and bubbly. Stir in 2 sliced green onions for a fresh touch, and let everything simmer together for another minute to blend the flavors. Serve the Mongolian Beef right away over rice for the best experience.
