Ingredients

Scale
  • 1 pound flank steak, thinly sliced against the grain
  • 2 tablespoons avocado oil or olive oil (for high-heat cooking)
  • 1 teaspoon xanthan gum (optional, helps with crispiness)
  • Salt and black pepper to taste
  • 4 cups fresh broccoli florets, washed and trimmed
  • 1 tablespoon avocado oil or olive oil
  • Pinch of sea salt
  • 3 tablespoons tamari or coconut aminos (low-sodium preferred)
  • 1 tablespoon sesame oil
  • 1 tablespoon rice vinegar
  • 1 teaspoon minced garlic (about 2 cloves)
  • 1 teaspoon freshly grated ginger
  • 1 teaspoon powdered erythritol or preferred keto-friendly sweetener
  • 1/4 teaspoon crushed red pepper flakes (optional, for a little kick)
  • Optional garnishes: toasted sesame seeds, thinly sliced green onions

Instructions

  1. Slice the flank steak thinly against the grain into 1/4-inch strips.
  2. In a bowl, combine beef slices with 1 tablespoon avocado oil, salt, pepper, and xanthan gum if using. Toss to coat evenly and let rest for 10 minutes at room temperature.
  3. Whisk together tamari, sesame oil, rice vinegar, minced garlic, grated ginger, erythritol, and red pepper flakes in a small bowl. Set aside.
  4. Heat 1 tablespoon oil in a skillet over medium-high heat. Add broccoli florets, sprinkle with sea salt, and stir-fry for 4-5 minutes until bright green and just tender. Remove broccoli and set aside.
  5. Increase heat to high. Add remaining 1 tablespoon oil to the pan. Spread beef strips in a single layer without crowding. Sear undisturbed for 2 minutes, then flip and cook for another 1-2 minutes. Work in batches if needed.
  6. Lower heat to medium. Return broccoli to the pan with beef. Pour sauce over and toss to combine. Cook for 2 minutes until sauce thickens and coats ingredients.
  7. Transfer to serving plate and garnish with toasted sesame seeds and sliced green onions if desired.

Notes

Pat beef dry before seasoning to ensure crispiness. Use high heat and avoid overcrowding the pan to prevent steaming. Marinate briefly with xanthan gum for extra crisp edges but it’s optional. Reheat leftovers gently in a skillet to maintain texture; avoid microwaving.
