Notes

Ingredients
For the steak:
  • 1 lb sirloin (or flank) steak, thinly sliced against the grain
  • 1 tbsp soy sauce (or coconut aminos)
  • 1 tsp cornstarch
  • 1 tsp toasted sesame oil
For the sauce:
  • 3 tbsp soy sauce (or coconut aminos)
  • 1 tbsp rice vinegar
  • 1 tsp honey or brown sugar
  • 2 tsp cornstarch
  • ¼ cup beef broth or water
For the stir fry:
  • 2 tbsp avocado or vegetable oil, divided
  • 2 medium zucchini, sliced into half moons
  • 1 onion, sliced
  • 3 garlic cloves, minced
  • 1 tbsp fresh ginger, grated
  • 1 tsp toasted sesame oil, to finish
  • Scallions and sesame seeds, to garnish
Instructions
  1. Toss the sliced steak with the soy sauce, cornstarch, and sesame oil; rest 10 minutes.
  2. Whisk together all the sauce ingredients and set aside.
  3. Heat 1 tbsp oil in a large pan over high heat. Sear the steak in batches, 1–2 minutes, until browned. Remove.
  4. Add the remaining oil, then the onion and zucchini. Stir fry over high heat 3–4 minutes until crisp tender. Add garlic and ginger for the last 30 seconds.
  5. Return the steak, pour in the sauce, and toss about 1 minute until glossy.
  6. Finish with sesame oil, scallions, and sesame seeds. Serve immediately.
Notes
  • Slice the steak thin against the grain; freeze it 30 minutes first for easier slicing.
  • Cook over high heat in batches so the steak sears and the zucchini stays crisp.
  • Use coconut aminos and skip the honey for a paleo or Whole30 version.
  • Best served fresh; leftovers keep 3–4 days.
Storage
  • Refrigerate leftovers up to 3–4 days.
  • Reheat in a hot skillet to keep the steak tender.
  • Not ideal for freezing (zucchini softens); freeze just the steak if needed.
