Ingredients

Scale

Lo Mein Sauce Ingredients

  • 1/4 cup soy sauce
  • 3 tbsp oyster sauce
  • 2 tbsp sesame oil
  • 1 tbsp brown sugar
  • 1/4 cup water
  • 1/2 tsp black pepper
  • 1 tbsp cornstarch


Instructions

  1. Prepare the sauce: In a bowl, mix together the soy sauce, oyster sauce, sesame oil, brown sugar, water, black pepper, and cornstarch until well combined and smooth, ensuring the cornstarch is fully dissolved for a thickening effect when heated.
  2. Cook the noodles: Follow the package instructions to cook your preferred noodles (e.g., egg noodles or spaghetti). Drain and set aside, ensuring they are not overcooked to maintain a perfect chewy texture.
  3. Stir-fry the noodles and add-ins: Heat a bit of oil in a large skillet or wok over medium-high heat. Add garlic and your choice of vegetables or meat, stir-frying until cooked through and fragrant. Then add the cooked noodles, tossing well to combine and heat through.
  4. Combine with sauce: Pour the prepared Lo Mein sauce over the hot noodles and stir continuously until the sauce thickens slightly and fully coats the noodles and stir-fried ingredients, ensuring every bite is flavorful.

Notes

  • You can customize this sauce by adding chili paste or fresh ginger for extra heat and flavor.
  • For a vegetarian version, substitute oyster sauce with mushroom sauce or hoisin sauce.
  • The cornstarch helps thicken the sauce when heated, so make sure it’s fully dissolved before adding it to the noodles.
  • Use fresh vegetables like bell peppers, carrots, and snap peas for a crunchier texture.
  • To make meal prep easier, sauce can be prepared ahead and stored in an airtight container for up to 3 days in the refrigerator.
