# Expert Advice:

01 -
  • The sauce clings to every noodle and vegetable in a way that makes you forget you're eating something you made yourself.
  • It comes together in under 40 minutes, which means dinner on a weeknight without the guilt of ordering takeout again.
  • The beef gets tender and caramelized while the vegetables stay crisp, so you get texture in every bite.
  • You can adjust the heat to match your mood, from gentle warmth to sweat-inducing fire.
02 -
  • Don't overcrowd the pan when searing the beef or it will steam instead of brown, and all that flavorful crust you're after will never form.
  • The sauce needs to be made before you start cooking because the moment you need it, you're already too busy; having it ready makes the whole process feel calm instead of frantic.
  • Fresh udon noodles are completely different from dried, and they won't hold the same way if you cook them ahead, so cook them just before you're ready to use them.
03 -
  • Keep a small bowl of water next to your stove in case the sauce starts to stick or caramelize too much—a splash of water brings it back to life.
  • Slice your beef ahead of time and let it sit with the cornstarch mixture while you prep everything else, giving the cornstarch time to work its magic.
  • Serve this immediately in a warm bowl because the noodles will continue to absorb the sauce and swell, making the dish less saucy as it sits.
