How to Prepare Super Easy Mongolian Beef (P.F. Changs Copycat)

Step 1: Prepare the Beef
Start by slicing the flank steak against the grain into thin strips. This helps ensure that the meat remains tender during cooking. Aim for pieces that are about 1/4 inch thick for the best texture.
Step 2: Coat the Beef
In a large bowl, toss the sliced beef with cornstarch until well-coated. The cornstarch will create a crispy exterior when cooked, giving you that signature Mongolian Beef texture.
Step 3: Heat the Oil
In a large skillet or wok, heat the vegetable oil over medium-high heat. Once hot, add the coated beef strips in a single layer. You may need to cook the beef in batches to avoid overcrowding the pan.
Step 4: Cook the Beef
Cook the beef for about 2-3 minutes on each side, or until browned and crispy. Remove the cooked beef from the skillet and set it aside on a plate.
Step 5: Prepare the Sauce
In the same skillet, add the minced ginger and garlic. Sauté for about 30 seconds until fragrant. Then, add the low-sodium soy sauce, brown sugar, water, and red pepper flakes. Stir to combine and bring to a simmer.
Step 6: Combine and Serve
Once the sauce has thickened slightly (about 2-3 minutes), return the beef to the skillet. Toss the beef in the sauce until well-coated. Cook for an additional minute to heat through, then remove from heat and garnish with sliced green onions.
