Method

Beef Marinade

  1. 1

    Prepare the Flank Steak

    Slice the flank steak against the grain into thin strips, approximately 1/4 inch thick.

  2. 2

    Marinate the Beef

    In a bowl, combine 1 cup of soy sauce, brown sugar, 2 tablespoons of cornstarch, and minced garlic. Add the sliced flank steak to the marinade, ensuring all pieces are coated. Cover and refrigerate for at least 30 minutes.

Cooking the Beef

  1. 3

    Heat the Pan

    In a large skillet or wok, heat 2 tablespoons of vegetable oil over medium-high heat until shimmering.

  2. 4

    Cook the Beef

    Remove the flank steak from the marinade and let excess marinade drip off. Add the beef to the hot skillet in a single layer. Cook for 2-3 minutes on each side until browned and cooked through. Remove from the pan and set aside.

Prepare the Vegetables

  1. 5

    Sauté the Vegetables

    In the same skillet, add chopped green onions, sliced bell pepper, and grated ginger. Stir-fry for 3-4 minutes until the vegetables are tender but still vibrant.

Make the Sauce

  1. 6

    Combine Ingredients

    In a bowl, whisk together 1 cup of soy sauce, rice vinegar, water, red pepper flakes, and sesame oil.

  2. 7

    Add Sauce to the Pan

    Pour the sauce mixture into the skillet with the sautéed vegetables. Bring to a simmer and cook for 2-3 minutes.

Combine and Serve

  1. 8

    Return Beef to the Pan

    Add the cooked flank steak back into the skillet with the sauce and vegetables. Toss to coat the beef in the sauce and heat through for another 2 minutes.

  2. 9

    Cook the Rice

    In a pot, combine 2 cups of white rice and 4 cups of water. Bring to a boil, then reduce heat to low, cover, and simmer for 15-20 minutes or until the rice is cooked and water is absorbed.

  3. 10

    Serve

    Serve Mongolian beef over a bed of fluffy white rice, garnished with additional chopped green onions if desired.
