Mongolian Beef

Tender strips of flank steak in a sweet, garlicky soy and ginger sauce with green onions. Slice and coat the beef ahead, then it cooks in about 10 minutes. Serve over White Rice. Serves 10.

Ingredients:

  • 3 pounds flank steak (or sirloin), sliced thin across the grain
  • 1/2 cup cornstarch
  • 1/2 cup vegetable oil, divided
  • 2 bunches green onions, cut into 2-inch pieces

Sauce:

  • 1 cup soy sauce
  • 1 cup water
  • 1 cup packed brown sugar
  • 2 tablespoons fresh ginger, minced
  • 8 cloves garlic, minced
  • 1 teaspoon sesame oil
  • 1 tablespoon cornstarch mixed with 2 tablespoons water

Instructions:

  1. Morning or afternoon: slice the beef 1/4 inch thick across the grain. Firming it in the freezer for 20 minutes makes slicing easier. Refrigerate.
  2. Mix the soy sauce, water and brown sugar in a jar and refrigerate. Mince the ginger and garlic and cut the green onions.
  3. At dinner: toss the beef with the 1/2 cup cornstarch until coated.
  4. Heat 2 tablespoons oil in a large skillet or wok over high heat. Sear the beef in 3 or 4 batches, 1 to 2 minutes per side, adding oil as needed. Move each batch to a plate.
  5. Lower the heat to medium. Add the ginger and garlic to the pan for 30 seconds, then the sauce. Simmer 3 to 4 minutes, then stir in the cornstarch slurry until glossy.
  6. Return the beef and add the green onions and sesame oil. Toss for 1 minute and serve over rice.

Cook's Notes:

  • Cooking in batches keeps the pan hot so the beef browns instead of steaming.
  • Sirloin works if flank steak is pricey.
