Vegetable Stir Fry

  • 8 ounces Udon noodles

  • ¼ cup green onion, thinly sliced
  • 3 cloves garlic, minced
  • 2 tablespoons olive oil

Stir Fry Sauce

  • 4 tablespoons soy sauce
  • 1 tablespoon mirin sauce
  • 2 teaspoon sesame oil
  • ¼ teaspoon ground black pepper
  • 2 teaspoon cornflour


  • In a pot add 6 cups of boiling water and cook the noodles according to the package directions. Note: this will vary significantly depending on the kidn of noodle you use. Drain and set aside.

Recipe Tips
  1. This recipe is very versatile. Feel free to swap out different vegetables. Snap peas, edamame, and zucchini all make great alternatives/additions. I also recommend trying this recipe with my Thai Peanut Sauce.
  2. Cook your noodles to al dente.Udon noodles typically take less time to cook than pasta. Make sure to keep an eye on them to prevent them from getting mushy.
  • For a gluten-free option, you can easily swap out the soy sauce for Tamari and consider using brown rice noodles in place of udon noodles.
  • For a grain-free option, consider swapping out the noodles for zucchini noodles.
