Ingredients

  • 1 1/2 pounds flank steak cut against the grain into 1" strips, see notes
  • 1 tablespoon arrowroot flour
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1 pound broccoli florets see notes
  • 1 cup white onion sliced
  • 2 tablespoons minced garlic roughly 8 cloves
  • 1 tablespoon minced ginger
  • 1/2 cup coconut aminos
  • 1 1/2 tablespoons fish sauce

Instructions

  • Lay the flank steak strips out on a cutting board and drizzle with 1 tablespoon of oil. Evenly sprinkle with arrowroot, salt, and pepper. Using a spoon or your hands, mix well until evenly coated. 
  • Heat up a large sauté pan over medium heat for 2 minutes. Add 2 tablespoons of oil, and let that heat through for another minute. Place the flank steak strips into the pan in a single layer, being sure not to overcrowd the pan. I like to do this in 2-3 batches. Cook for 5 minutes (2-3 minutes per side) until browned and crispy on the outside. Transfer to a plate.
  • Blanch the broccoli: bring a medium pot of water to a boil. Add in the broccoli florets and cook for 3 minutes. Drain thoroughly and dry as well as possible. Set aside.
  • Turn the stove back on to medium heat. Once the pan is hot, add onions and a big pinch of salt. Sauté for about 5 minutes, stirring occasionally until soft.
  • Add garlic and continue cooking for 1 minute, stirring often. Mix in broccoli florets and cook for about 4 minutes until tender. Add in ginger and continue stirring for 1 minute.
  • Place the cooked steak strips back into the pan (with their juices) and pour in the coconut aminos and fish sauce. Cook over medium to medium-low heat until the sauce has reduced down by about 1/2 to 2/3 and has slightly thickened, about 4-5 more minutes.
  • Remove from heat and serve alongside your favorite rice or cauliflower rice. Garnish with sesame seeds.

Notes

  • Be sure you are cutting the flank steak against the grain. This means cutting it in the same direction the muscle fibers run.
  • If you are buying already trimmed florets, purchase 1 pound. If you are buying broccoli crowns, be sure you have 1 pound after you cut them into florets (this will roughly be 4-5 crowns depending on their size.)
