# Expert Suggestions:

01 -
  • It comes together in under 40 minutes, which means weeknight dinner that tastes like you actually tried.
  • The spice level is completely in your hands, so it's friendly to heat-lovers and cautious eaters alike.
  • Tender beef, chewy noodles, and vegetables that stay crisp instead of turning to mush—it's the balance that makes it crave-worthy.
02 -
  • Don't move the beef around constantly while it's searing—let each piece get a golden crust before you stir it. This is the hard-won lesson that separates a good stir fry from a steamed one.
  • Keep your ingredients prepped before you start cooking. Once the wok is hot, there's no time to chop anything, and rushed chopping leads to uneven cooking.
  • High heat is your friend, but only if your oil is hot enough first. If the oil isn't shimmering, wait another 30 seconds.
03 -
  • Don't overcrowd the wok when you're cooking the beef—work in batches if you need to, so everything gets that beautiful sear instead of steaming.
  • If your sauce seems too thin or too thick, cornstarch slurry mixed into a splash of water fixes it quickly without throwing off your flavors.
