Ingredients

Scale

For the Beef:

  • 2 lbs flank steak
  • 1/2 cup cornstarch
  • 46 tablespoons coconut oil or cooking oil of choice

For the Sauce:

  • 1/2 cup soy sauce (use tamari for gluten-free)
  • 1/2 cup brown sugar
  • 1/4 cup water
  • 1 tablespoon cornstarch
  • 1/4 teaspoon red pepper flakes
  • 3 green onions (white and green parts, thinly sliced)
  • 3 cloves garlic (minced)
  • 1 tablespoon fresh ginger (grated)

For Serving:

  • Cooked rice
  • Extra sliced green onions

Instructions

  1. Prepare the Beef: Slice the flank steak against the grain into thin strips. Place the steak strips into a Ziploc bag and add 1/2 cup cornstarch. Seal the bag and toss well to evenly coat all pieces in cornstarch.
  2. Make the Sauce: In a small bowl, combine 1/2 cup soy sauce (or tamari), 1/2 cup brown sugar, 1/4 cup water, 1 tablespoon cornstarch, and 1/4 teaspoon red pepper flakes. Stir thoroughly to dissolve the sugar and cornstarch.
  3. Brown the Beef: Heat a large skillet over medium-high heat. Add 2-3 tablespoons coconut oil and let it heat until hot. Shake off excess cornstarch from half the beef strips. Add them in an even layer, breaking up any chunks. Cook undisturbed for 4-5 minutes until crispy and browned. Flip with tongs and cook the other side for 2-3 minutes. Transfer cooked beef to a plate. Repeat this process with the remaining oil and beef.
  4. Cook Aromatics and Sauce: If necessary, add a bit more oil to the pan and reduce heat to medium. Add sliced green onions, minced garlic, and grated ginger. Stir and cook carefully for 1-2 minutes without burning. Pour in the prepared sauce mixture, stirring to combine. Bring the sauce to a simmer and allow to cook for 4-5 minutes until it thickens.
  5. Combine and Serve: Return the browned beef to the skillet, tossing it with the thickened sauce so the beef stays crispy. Serve immediately over cooked rice and garnish with extra sliced green onions. Enjoy your delicious Beef Teriyaki!

Notes

  • MAKE IT GLUTEN-FREE: Use tamari or a gluten-free soy sauce instead of regular soy sauce.
  • HOW TO SLICE FLANK STEAK: Slice against the grain for the most tender bite. Cut across the muscle fibers rather than along them.
  • Shake off excess cornstarch before browning the beef to ensure a light coating and optimal crispiness.
  • Serve immediately after tossing with the sauce to maintain the beef’s crispy texture.
  • Pair with steamed rice and vegetables like broccoli for a complete meal.
