  • Wok
  • Low Carb Brown Sugar
  • Silicone Tongs


  • 1 1/2 pounds flank steak thinly sliced
  • 4 cups frozen broccoli florets (16 ounce bag)
  • 1 tbsp vegetable oil or olive oil
  • 3 stems green onions
  • 1 tbsp toasted sesame oil
  • 1 tbsp minced garlic
  • 1 tsp minced ginger
  • 1/3 cup lite soy sauce
  • 3 tbsp low carb brown sugar or keto granulated sweetener
  • 1 tbsp sriracha or pinch red pepper flakes
  • 1/2 tsp xanthan gum


  • Place steak on a cutting board. Using a sharp knife, cut across the grain of meat, slicing the steak into very thin slices, 2 -3 inches long. Set aside.
  • Microwave or steam broccoli to crisp-tender. Drain completely and set aside.
  • To a small mixing bowl add soy sauce, garlic, ginger, low carb brown sugar and sriracha. Whisk to blend. Add sesame oil and xanthan gum to a separate small bowl. Stir until completely blended. Pour into soy sauce mixture and whisk to blend. Set aside.
  • Heat the vegetable oil in a wok or deep fry pan over MED-HIGH heat. Add the meat to the pan and toss to cook until starting to brown, about 2 minutes. Add the green onions, Keep cooking until the meat is fully done, about 2 - 3 more minutes. The onions will get soft and release their flavor.
  • Toss the broccoli into the pan and stir to combine.
  • Pour the sauce over the stir fry. Toss so that everything is coated. Keep tossing and cooking until the sauce starts to thicken, about 1-minute. Serve hot!
  • Refrigerate any leftovers in an airtight container for up to 3 days.
