What You’ll Need

Udon stir-fry noodles: The noodles used in this recipe are pre-cooked, which makes this dish come together in minutes. They have a squishy, chewy texture that is so satisfying. I found mine at Trader Joe’s (Thai Wheat Noodles), but Walmart also carries a similar kind (Udon Stir-fry Noodles).

Finely chopped veggies: I used green onion, carrot, and Napa cabbage which really complement the dense, chewy noodles by offering a nice crunch and lightness to the dish. You could sub out other vegetables, as well, such as broccoli, snap peas, bell peppers, and/or mushrooms.

Spicy udon sauce (recipe below): This sauce is so easy and hits all the right notes. It’s salty, savory, sweet, and just the right amount of spicy. You could definitely leave out or reduce the amount of chili garlic sauce if serving to kids or if spice isn’t your thing.

How to Make

  1. Prepare your veggies. I recommend getting all of your vegetables chopped and ready BEFORE making the sauce and starting to cook. It’ll make things go much smoother and quicker.
  2. Make the sauce. This sauce is super easy to make. Just combine all of the ingredients listed and whisk together with a fork.
  3. Sauté the veggies. Since the veggies are finely chopped, they become perfectly tender within just a few minutes.
  4. Add the sauce. This is when it really starts to smell amazing. Sautéing the veggies and sauce together for a minute or two creates depth and helps develop the flavor for the dish.
  5. Add the noodles. This step takes just a little bit of patience. Be sure to be gentle with the noodles so they don’t break. You’ll want to let them break apart on their own as they heat up.

Notes & Tips

  • Feel free to swap or add extra veggies. Others that would be lovely in this dish are broccoli, snap peas, bell peppers, and mushrooms. Depending on the specific vegetable, you may want to sauté slightly longer to make sure they’re perfectly tender.
  • If you can’t find the pre-cooked udon noodles (see notes above under ingredient information), you could substitute for other noodles. Just make sure you follow the instructions on the package for cooking prior to adding to the veggies and sauce mixture.
  • Add a protein to the dish to make it even more satisfying. Try shredded chicken, chicken meatballs, ground beef, edamame, or a fried egg.

Storage & Reheating

  • These spicy udon noodles are best served and eaten immediately, however, they can be stored in the refrigerator for up to four days after cooking.
  • To reheat, simply sprinkle with water, cover, and microwave until hot.

  1. The noodles used in this recipe are pre-cooked, like these Thai Wheat Noodles from Trader Joe’s or these Udon Stir Fry Noodles from Walmart. If you can’t find these, you can substitute another type of noodle, just make sure to follow package directions for cooking prior to adding to recipe.
  2. This is the chili garlic sauce I used. You could substitute sriracha or another hot sauces as well.
