Notes

  • Slice the beef thinly to ensure it turns out tender instead of chewy.
  • Use low sodium broth, as the final seasoning will depend on both the broth and sauce.
  • Add the broccoli at the end of cooking to keep it bright and not overcooked.
  • Do not skip the cornstarch slurry, as it creates the thick, glossy sauce.
  • When reheating, add a splash of water or broth to loosen the sauce and restore the texture.
