# Expert Suggestions:

01 -
  • Ready in 30 minutes flat, no complicated techniques required.
  • The beef stays tender when you slice it right and cook it quick, which always impresses people at the table.
  • That sesame oil fragrance filling your kitchen is worth the price of admission alone.
02 -
  • High heat is your friend here—it's what gives you that restaurant sear and keeps vegetables crisp instead of steamed.
  • Don't skip the marinade on the beef, and don't skip rinsing the noodles; both of these small steps change everything about the texture.
03 -
  • If your sauce seems thin, it's probably the cornstarch—whisk it properly so there are no lumps, and it'll thicken as things heat up.
  • Cold leftover lo mein reheats beautifully in a hot wok with a splash of water and a dash of sesame oil, making great lunch the next day.
