This recipe uses simple yet essential ingredients, each chosen to contribute to the perfect balance of flavor, texture, and a gorgeous appearance. With pantry staples like tamari and sesame oil, fresh vegetables for crunch and color, plus aromatic garlic and onions, everything comes together beautifully.

  • 4 tablespoons Tamari sauce: Adds a rich, salty umami base that's gluten-free and flavorful.
  • 1 tablespoon Mirin: Brings a subtle sweetness and depth typical of Asian cooking.
  • 1 tablespoon granulated sugar: Balances savory and tangy with a gentle touch of sweetness.
  • 1 tablespoon pure Asian sesame oil: Infuses an irresistible nutty aroma.
  • ¼ teaspoon freshly ground black pepper: Adds mild heat and nuance.
  • 8 ounces fresh Asian noodles (or dry spaghetti): The chewy, soft foundation of the dish.
  • 2 tablespoons pure Asian sesame oil: For tossing noodles and enhancing the sauce.
  • 2 tablespoons olive oil: The perfect fat to sauté your vegetables gently.
  • 1 whole onion (thinly sliced): Provides sweetness and texture.
  • 6 cloves garlic (minced): Adds aromatic punch and depth.
  • 1 ½ cups matchstick carrots (pre-cut from store): Contributes crunch and bright color.
  • 1 ½ cups bell pepper (seeded and roughly chopped): Delivers sweetness and vibrant hues.
  • Thinly sliced green onions: For fresh garnish and added layers of flavor.
  • Toasted sesame seeds: Perfect for a final nutty crunch.
  • Sriracha (optional): For a spicy kick if you like things hot.

How to Make Lo Mein Noodles with Vegetables and Sesame Sauce Recipe

Step 1: Boil the Noodles

Fill a large pot with generously salted water and bring it to a boil. Cook your fresh Asian noodles or dry spaghetti according to the package instructions until just al dente. It’s crucial not to overcook them, as they will continue to cook slightly when tossed with the sauce. Once done, drain the noodles well and toss them gently with 2 tablespoons of Asian sesame oil to prevent sticking and start infusing that lovely nutty flavor.

Step 2: Whisk the Sesame Sauce

While the noodles are cooking, mix together the tamari sauce, mirin, granulated sugar, 1 tablespoon of pure Asian sesame oil, and freshly ground black pepper in a bowl. Whisk everything well until the sugar dissolves completely, creating a luscious sauce that will envelop your noodles and vegetables with a rich, balanced flavor.

Step 3: Sauté the Vegetables

Heat 2 tablespoons of olive oil in a large, deep skillet or wok over medium-high heat. As the oil shimmers, add the thinly sliced onions and minced garlic. Stir them around for about 2 minutes until they become fragrant and slightly translucent. Next, throw in the matchstick carrots and bell pepper pieces, cooking for an additional 3 to 4 minutes. You want the veggies to soften but still keep a bit of their crunch and vibrant color.

Step 4: Toss Everything Together

Now it’s time to bring it all together. Add your cooked noodles into the skillet with the vegetables. Pour the prepared sesame sauce evenly over everything, and toss gently but thoroughly to make sure all the noodles and veggies are coated in that irresistible sauce. The heat from the skillet will further help the flavors meld together perfectly. Serve immediately for the best texture and freshness.

Garnishes

To elevate the dish visually and flavor-wise, sprinkle thinly sliced green onions and toasted sesame seeds across the top right before serving. These simple garnishes add a fresh burst of flavor and a delightful crunch, making each bite more enjoyable.

Side Dishes

Lo Mein is pretty filling on its own, but it pairs beautifully with lighter sides like steamed or stir-fried greens (think bok choy or snap peas), or a fresh cucumber salad to cut through the richness. For a heartier meal, you could also serve alongside marinated tofu or grilled chicken.

Creative Ways to Present

Try serving your lo mein in individual small bowls for a charming, restaurant-style presentation. Drizzle a little extra sesame oil or sriracha on top for added flair and zing. Another fun idea is to place it on a bed of butter lettuce leaves for a fresh wrap option — it adds a crisp texture and makes for a lovely hand-held snack.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer any leftover lo mein into an airtight container and store in the refrigerator. It will keep beautifully for up to 3 days. This makes it a convenient and tasty next-day lunch or dinner.

Freezing

While freezing is possible, keep in mind that the vegetables may become softer after thawing. If you choose to freeze, place the noodles and vegetables in a freezer-safe container or bag, removing as much air as possible. They will last up to 2 months frozen. Thaw overnight in the fridge before reheating.

Reheating

For the best texture when reheating, warm your lo mein in a skillet over medium heat with a splash of water or extra sesame oil to refresh the noodles and prevent sticking. Stir gently until heated through. Avoid microwaving if possible, as it can dry out the dish and sacrifice those lovely textures you worked hard to create.

FAQs

Can I use other noodles instead of Asian noodles?

Absolutely! If you don’t have fresh Asian noodles on hand, dry spaghetti works perfectly as a replacement. Just be sure to cook to al dente so the noodles don’t get mushy after tossing with the sauce and vegetables.

Is this recipe vegetarian or vegan?

Yes! This Lo Mein Noodles with Vegetables and Sesame Sauce Recipe is plant-based, packed with veggies and flavorful sauces that are naturally vegan. Just double-check your tamari or soy sauce to ensure it’s vegan-friendly.

Can I add protein to this recipe?

Definitely. Adding tofu, chicken, shrimp, or beef strips can turn this dish into a heartier main course. Simply cook the protein separately or in the skillet before adding the vegetables, and then combine everything in the final toss.

How spicy is this dish?

By itself, this recipe is mild and savory with no inherent heat. However, you can spice things up easily by adding sriracha or chili flakes to taste, either stirred into the sauce or drizzled on top when serving.

What can I substitute for mirin if I don’t have it?

If mirin isn’t available, a dry sherry or a mix of rice vinegar and a pinch of sugar makes a good stand-in. It provides the needed sweetness and acidity to balance the tamari sauce beautifully.

Final Thoughts

There’s just something so comforting and joyful about whipping up this Lo Mein Noodles with Vegetables and Sesame Sauce Recipe at home. It’s quick enough for busy nights but indulgent enough to savor slowly. Each bite delivers a marvelous blend of textures and flavors that always leaves me wanting more. I truly hope you enjoy making and sharing this dish as much as I do — it’s food that feels like a warm, delicious hug!

Ingredients

Sauce Ingredients

  • 4 tablespoons Tamari sauce
  • 1 tablespoon mirin
  • 1 tablespoon granulated sugar
  • 1 tablespoon pure Asian sesame oil
  • ¼ teaspoon freshly ground black pepper

Noodles

  • 8 ounces fresh Asian noodles (or dry spaghetti)
  • 2 tablespoons pure Asian sesame oil

Vegetables and Garnishes

  • 2 tablespoons olive oil
  • 1 whole onion (thinly sliced)
  • 6 cloves garlic (minced)
  • 1 ½ cups matchstick carrots (pre-cut from store)
  • 1 ½ cups bell pepper (seeded and roughly chopped)
  • Thinly sliced green onions (for garnish)
  • Toasted sesame seeds (for garnish)
  • Sriracha (optional, for serving)


Instructions

  1. Boil the Noodles: Fill a large pot with generously salted water and bring to a boil. Add the fresh Asian noodles or dry spaghetti and cook according to package instructions until al dente. Drain the noodles thoroughly to prevent them from becoming mushy.
  2. Toss Noodles with Sesame Oil: Immediately after draining, toss the hot noodles with 2 tablespoons of pure Asian sesame oil to prevent sticking and infuse them with flavor. Set the noodles aside while you prepare the rest of the dish.
  3. Whisk the Sauce: In a small bowl, combine 4 tablespoons tamari sauce, 1 tablespoon mirin, 1 tablespoon granulated sugar, 1 tablespoon Asian sesame oil, and ¼ teaspoon freshly ground black pepper. Whisk well until the sugar is dissolved and the sauce is smooth. Set aside.
  4. Sauté Aromatics: Heat 2 tablespoons olive oil in a large, deep skillet or wok over medium-high heat. Once hot, add the thinly sliced onions and minced garlic, stirring frequently for about 2 minutes until fragrant and slightly softened.
  5. Add Vegetables: Add the matchstick carrots and chopped bell peppers to the skillet. Stir-fry the vegetables for 3 to 4 minutes, or until they become tender but still retain some crunch.
  6. Toss Noodles and Sauce: Add the cooked and oiled noodles into the skillet with the vegetables. Pour the prepared sauce evenly over the noodles and vegetables. Gently toss everything together to ensure all ingredients are coated well with the sauce and heated through.
  7. Serve and Garnish: Transfer the lo mein to serving plates or bowls. Garnish with thinly sliced green onions and toasted sesame seeds. Add a drizzle of sriracha if you prefer some heat. Serve warm and enjoy!

Notes

  • Be careful not to overcook the noodles to keep them chewy and enjoyable.
  • You can substitute tamari sauce with soy sauce if you don’t have tamari but tamari is gluten-free and preferred for richer flavor.
  • Feel free to add protein such as tofu, chicken, or beef to customize your lo mein.
  • Mirin adds a subtle sweetness and depth, but you can use a sweet rice wine or a small amount of honey as a substitute if needed.
  • Adjust the amount of sriracha according to your spice tolerance.
