(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

  1. Prepare the beef: Slice the flank steak or sirloin into thin strips against the grain. This helps ensure the meat stays tender. Set aside.

  2. Make the sauce: In a small bowl, combine soy sauce, brown sugar, water, and cornstarch. Stir until the cornstarch dissolves completely. Set the sauce mixture aside.

  3. Cook the beef: Heat vegetable oil in a large skillet or wok over medium-high heat. Add the sliced beef to the skillet and cook for 3-4 minutes until browned and slightly crispy. Remove the beef from the skillet and set aside.

  4. Prepare the sauce: In the same skillet, add sesame oil, garlic, ginger, and red pepper flakes (if using). Cook for 1-2 minutes until fragrant and softened.

  5. Combine and simmer: Add the sauce mixture to the skillet and bring to a simmer. Stir the sauce for 2-3 minutes, allowing it to thicken slightly.

  6. Add beef back in: Return the cooked beef to the skillet and toss it in the sauce until fully coated. Cook for another 2-3 minutes to heat the beef through and absorb the flavors.

  7. Garnish and serve: Remove from heat and garnish with sliced green onions. Serve the Mongolian beef over steamed rice and enjoy!
