# Expert Tips:

01 -
  • It comes together faster than takeout and tastes even better because you control the sauce balance.
  • The marinade makes the beef so tender and flavorful that even skeptical eaters ask for seconds.
  • It's the kind of dish that feels impressive but honestly just requires confidence with high heat and good timing.
02 -
  • High heat is your best friend here, a medium pan will give you steamed vegetables and rubbery beef instead of the crisp, caramelized results you're after.
  • Don't fully cook the broccoli in its marinated state, it'll turn mushy when it hits the sauce, aim for crisp-tender and let the residual heat finish the job.
  • Cornstarch in both the beef marinade and the sauce is what creates that silky, glossy coating that makes takeout so addictive.
03 -
  • Prep everything before you start cooking, there's no time to chop garlic once the pan gets hot, and that's when mistakes happen.
  • If your noodles stick together after draining, toss them with just a tiny bit of oil, it's an old restaurant trick that saves so much frustration.
