Ingredients

8 oz. spaghetti (gluten-free if desired)
8 oz. mushrooms (I use cremini)
5 oz. snow peas (about 1.5 cups)
2 medium carrots
6 green onions
3–4 cloves garlic
1/4 cup tamari (or less, to taste)
Optional: 1/2 tsp. freshly grated ginger
Optional: 2 tsp. toasted sesame oil
Garnish: sesame seeds, mung bean sprouts

Equipment

Large pot for boiling pasta
Large skillet or sauté pan
Knife and cutting board
Colander
Tongs or pasta fork

Prep: how to get everything ready

Prep is the key to a fast, relaxed cooking rhythm. Clean the mushrooms with a damp towel and slice them thinly. Trim the snow peas and rinse them under cold water. Peel and julienne or shave the carrots into thin ribbons so they cook quickly. Slice the green onions on the diagonal into thin pieces, keeping the white and green parts separate if you like to add the green as a fresh garnish. Mince the garlic and, if using, grate the ginger finely so it blends smoothly into the sauce.

Step-by-step instructions

Bring the pasta water to a boil: Fill a large pot with water and bring it to a rolling boil over high heat. Salt the water lightly if desired. Add 8 oz. spaghetti and cook according to package instructions until al dente (usually a minute or two less than fully tender). Reserve about 1/2 cup of the starchy pasta cooking water, then drain the spaghetti in a colander and set it aside.
Prepare the vegetables while the pasta cooks: While the pasta is boiling, slice 8 oz. mushrooms, trim and rinse 5 oz. snow peas, and peel and julienne 2 medium carrots. Slice 6 green onions on the diagonal and mince 3–4 cloves garlic. If you’re using 1/2 tsp. freshly grated ginger, grate it now and keep it with the garlic.
Sauté the mushrooms first: Heat a large skillet over medium-high heat. Add a small splash of neutral oil or a light drizzle of water if you prefer oil-free sautéing. Add the sliced mushrooms and cook, stirring occasionally, until they begin to release their liquid and turn golden at the edges, about 4–5 minutes.
Add carrots and snow peas: Add the julienned carrots and the snow peas to the skillet with the mushrooms. Sauté for 2–3 minutes until the carrots soften slightly and the snow peas are bright green and still crisp-tender.
Introduce the aromatics: Push the vegetables to one side of the skillet and add the minced garlic and grated ginger (if using) to the cleared space. Cook for 30–45 seconds, stirring, until fragrant but not browned. Then toss the garlic and ginger with the vegetables so everything is evenly combined.
Combine the spaghetti and tamari: Add the drained spaghetti to the skillet with the vegetables. Pour in 1/4 cup tamari (use slightly less if you prefer a milder salt level). Toss everything together with tongs or two forks until the pasta is coated and the tamari is distributed evenly.
Adjust the sauce and texture: If the mixture looks dry or the tamari seems too concentrated, add 1–2 tablespoons of the reserved pasta cooking water at a time until the sauce loosens and glazes the noodles. You may not need the full 1/2 cup; just use enough to achieve a glossy coating.
Finish with green onions and sesame oil: Stir in the sliced white parts of the 6 green onions and, if using, 2 teaspoons toasted sesame oil. Taste and adjust seasoning — add a touch more tamari if you want it saltier, or a small splash of water to calm intensity.
Plate and garnish: Divide the pasta among bowls. Scatter the green parts of the green onions over the top, sprinkle with sesame seeds, and add a handful of mung bean sprouts for crunch. Serve immediately while warm.

Troubleshooting and tips

If your spaghetti sticks together after draining, toss it with a teaspoon of oil or a small splash of the reserved pasta water to loosen it before adding to the skillet.
Want more color? Add thinly sliced bell pepper, baby spinach, or shredded cabbage at the same time as the carrots.
If you like heat, add a pinch of red pepper flakes or a small drizzle of chili oil when you finish the dish.
For extra protein, stir in cooked edamame, baked tofu cubes, or shredded cooked chicken right before serving.
To make this recipe gluten-free, use a certified gluten-free spaghetti and double-check the tamari label for gluten-free status.

Make-ahead and storage

This dish is best eaten the day it’s made, but you can refrigerate leftovers in an airtight container for up to 3 days. Reheat gently in a skillet over medium-low heat with a splash of water to restore moisture, or microwave in short bursts, stirring between intervals. Add a fresh sprinkle of sesame seeds and sliced green onions after reheating to refresh the flavors and texture.

Variations to try

Sesame-Ginger Boost: Increase the grated ginger to 1 teaspoon, add 1 tablespoon rice vinegar, and finish with the toasted sesame oil for a brighter, tangier sauce.
Nutty Crunch: Stir in 2 tablespoons chopped roasted peanuts or cashews for crunch and richness.
Sriracha-Lime: Mix 1–2 teaspoons Sriracha with the tamari before tossing with the pasta, and add a squeeze of lime at the end for a tangy, spicy twist.
Herb Freshness: Toss in a handful of cilantro or basil leaves just before serving for herbal brightness.

Serving suggestions

Serve this pasta with a simple green salad or steamed vegetables to round out the meal. A cold cucumber salad or a bowl of miso soup complements the garlicky tamari flavors nicely. This dish also pairs well with pickled vegetables for a crisp, acidic contrast.

Notes on ingredients

Use 8 oz. spaghetti — traditional wheat or gluten-free — depending on your preference. The recipe calls for cremini mushrooms for their meaty texture and deep flavor, but button mushrooms work fine too. Snow peas add a pop of color and snap; if you prefer, sugar snap peas can be used instead. Tamari supplies the savory backbone of the sauce; use less than the 1/4 cup if you prefer a subtler saltiness. Garlic is essential here — the dish relies on 3–4 cloves for that robust, aromatic foundation. Optional grated ginger and toasted sesame oil add warmth and depth, but the recipe is delicious without them.
