  • 2 Tbsp vegetable oil divided

  • 2 cloves garlic minced

  • 1 Tbsp toasted sesame seeds

Lo- Mein Sauce

  • 6 Tbsp light soy sauce
  • 3 Tbsp dark brown sugar
  • 2 tsp sesame oil
  • 1 tsp sriracha sauce or to taste
  • 1 Tbsp corn starch


  • Mix all ingredients for sauce in a small bowl and set aside.
  • Bring a large pot of water to a boil.
  • While waiting for the water to boil, heat a wok or large deep skillet over medium-high heat and add 1 tablespoon of vegetable oil.
  • Add the beef and cook until no longer pink, then remove from the pan to a plate and cover with foil to keep warm.
  • Drain any liquid from the pan then add remaining one tablespoon of oil, garlic and vegetables. Meanwhile, drop the noodles in the boiling water and cook according to package directions. (5-9 minutes depending on noodle used)
  • Cook the vegetables until they begin to soften, then add the beef back to the pan. Drain the noodles and add them to the pan.
  • Pour the sauce into the pan and. Cook while tossing 2-3 minutes until heated through, the noodles are coated and sauce has slightly thickened.
  • Add sliced green onion and toasted sesame seeds and serve.


If you would prefer a darker sauce you can use 3 tablespoons of each dark and light soy sauce instead of 6 tablespoons of light.
If you don't like spice, simply omit the sriracha.
If you can't tolerate garlic, fresh ginger makes a great substitute in this recipe.
You can substitute any of the vegetables you like.  If you want to keep things really simple, go ahead and use a bag of ready-to-use stir fry vegetables.
