Sesame Teriyaki Chicken Spaghetti – A Savory Weeknight Favorite
This Sesame Teriyaki Chicken Spaghetti hits that sweet spot between comfort food and fresh, bright flavor. Think juicy chicken, glossy teriyaki sauce, and spaghetti that soaks it all up, finished with toasted sesame and a pop of green onions. It’s fast, satisfying, and friendly for weeknights.
You don’t need a special pan or fancy ingredients—just a few pantry staples and 30 minutes. If you like takeout-style teriyaki, this brings the vibe home with a fun pasta twist.
Ingredients
Method
- Prep the sauce. In a bowl, whisk soy sauce, water, brown sugar (or honey), rice vinegar, and mirin if using. In a separate small cup, mix cornstarch with a tablespoon of water to make a slurry. Set both aside.
- Cook the spaghetti. Boil in salted water until just shy of al dente. Reserve 1/2 cup pasta water, then drain. Toss with a teaspoon of oil to prevent sticking.
- Season and sear the chicken. Pat the chicken dry. Season lightly with salt and pepper. Heat neutral oil in a large skillet over medium-high. Cook chicken in an even layer until browned and cooked through, about 5–7 minutes. Remove to a plate.
- Sauté aromatics. In the same skillet, add a touch more oil if needed. Add garlic, ginger, and the white parts of the green onions. Cook 30–45 seconds until fragrant.
- Add veggies (optional). Toss in bell pepper, snap peas, or broccoli. Stir-fry 2–3 minutes until crisp-tender.
- Build the teriyaki. Pour in the soy mixture and bring to a gentle simmer. Stir the cornstarch slurry, then drizzle it in while stirring. Cook 1–2 minutes until the sauce thickens and turns glossy.
- Combine. Return chicken to the pan, add cooked spaghetti, and toss to coat. If it seems tight, splash in reserved pasta water a little at a time until silky.
- Finish. Turn off the heat. Stir in sesame oil, most of the toasted sesame seeds, and most of the green onion tops. Taste and adjust salt, sweetness, or acidity if needed.
- Serve. Plate and sprinkle with remaining sesame seeds and green onions. Add a pinch of red pepper flakes if you like heat.
Why This Recipe Works
This recipe blends familiar flavors with a simple technique. Spaghetti holds sauce beautifully, giving every bite a balanced mix of sweet, salty, and savory.
A quick cornstarch slurry turns the teriyaki into a silky glaze that clings to the noodles and chicken. Toasted sesame seeds and sesame oil add nutty depth, while fresh ginger and garlic keep it lively. It’s a one-pan-plus-pot situation, so cleanup stays easy.

Keeping It Fresh
Leftovers keep well for up to 3 days in an airtight container. Add a splash of water when reheating to loosen the sauce.
For best texture, reheat gently on the stove over low heat or in the microwave in short intervals, stirring in between. If you plan ahead, store the noodles and sauce-chicken mixture separately to keep the spaghetti from over-absorbing.
Why This is Good for You
- Lean protein: Chicken supports muscle repair and keeps you satisfied.
- Sesame goodness: Sesame seeds and sesame oil provide healthy fats and a satisfying nutty flavor, so a little goes a long way.
- Balanced energy: Pasta offers steady carbs; pairing with protein and veggies helps keep energy stable.
- Ginger and garlic: These bring big flavor with minimal calories and are staples in many wholesome, home-cooked meals.
Pitfalls to Watch Out For
- Overcooking the pasta: Pull it a minute early. It will finish in the sauce.
- Skipping the slurry: Without cornstarch, the sauce won’t cling.
Don’t add dry cornstarch directly—always mix with water first.
- Waterlogged veggies: Add them after aromatics and cook hot and fast to avoid sogginess.
- Too salty sauce: Brands of soy sauce vary. Taste before adding salt to the chicken, and thin with water if needed.
- Overcrowded pan: Sear chicken in batches for good browning and better flavor.
Alternatives
- Protein swaps: Use shrimp (cooks in 2–3 minutes), thinly sliced beef, or firm tofu (press and pan-sear until crisp).
- Noodle options: Swap spaghetti for udon, soba, rice noodles, or whole-wheat spaghetti. Adjust cook times accordingly.
- Gluten-free: Choose gluten-free spaghetti and use tamari or coconut aminos in place of regular soy sauce.
- Sugar options: Use honey, maple syrup, or a reduced amount of brown sugar.
Start with 2 tablespoons and add to taste.
- Veggie boost: Add mushrooms, baby spinach, or shredded cabbage. Toss greens in at the end so they wilt gently.
- Citrus twist: Finish with a squeeze of fresh orange or lime for brightness.
FAQ
Can I make the sauce ahead?
Yes. Mix the soy, water, sugar, vinegar, and mirin up to 3 days in advance and refrigerate.
Add the cornstarch slurry right before cooking so it doesn’t thicken in the fridge.
Do I have to use sesame oil?
No, but it adds a signature nutty finish. If you skip it, consider a few extra toasted sesame seeds or a drizzle of neutral oil to carry the flavors.
What if I only have chicken breasts?
That works. Slice them thinly against the grain and don’t overcook.
Breasts can dry out faster than thighs, so watch the pan closely and pull them as soon as they’re done.
Can I make it spicy?
Absolutely. Add red pepper flakes to the sauce, a squirt of sriracha, or sliced fresh chili with the aromatics. Start small and build up to your heat tolerance.
How can I thicken the sauce without cornstarch?
Use arrowroot powder in the same amount, or reduce the sauce a little longer before adding pasta.
Keep heat moderate to prevent clumping with alternative thickeners.
Is this meal good for meal prep?
Yes. Portion into containers and add a handful of quick-cooking veggies (like spinach) just before reheating for freshness. Reheat with a splash of water to keep it saucy.
