About This Recipe

This recipe is an arranged variation of our Teriyaki Chicken recipe. For the full teriyaki chicken recipe, see Teriyaki Chicken | Juicy & Glazed Japanese Classic Recipe.
Leftover teriyaki chicken finds its best second act in this Japanese-style one-pan pasta. The sweet-savory teriyaki glaze seeps into the noodles as they cook, combining with the umami of mushrooms, the freshness of spinach, and a soy butter finish to create something far more satisfying than the sum of its parts.
No separate pot needed — the pasta cooks directly in the pan alongside the other ingredients, absorbing the teriyaki flavor all the way through. Everything comes together in about 12 minutes, with minimal washing up.
Top with a soft-cooked egg, sesame seeds, or a scattering of green onions for a bowl that feels like a proper meal despite the humble starting point.
Easy enough for a busy weeknight, yet satisfying enough to feel like a proper meal — a Japanese-style one-pan pasta worth coming home to.

Teriyaki sauce 2–3 tbsp
See : Teriyaki Chicken | Juicy & Glazed Japanese Classic Recipe - Soy sauce 1–2 tsp
- Kombu dashi powder (or any dashi, chicken bouillon, or consommé) 1 tsp

Instructions
| 1 |
![]() | Cut the teriyaki chicken into bite-sized pieces. Cut the spinach into 4–5 cm lengths. Trim and separate the shimeji mushrooms. Grate the garlic. |
| 2 |
![]() | Heat the olive oil in a deep frying pan over medium heat. Add the shimeji mushrooms with a pinch of salt and sauté until softened and fragrant. Tip Sautéing the mushrooms thoroughly removes excess moisture, which concentrates their umami and prevents the finished dish from becoming watery. |
| 3 |
![]() | Add the water, kombu dashi powder, and grated garlic to the pan. Bring to a boil. Break the spaghetti in half, add to the pan, and cook over medium heat for the time indicated on the package. Tips

![]() | Once most of the liquid has been absorbed, add the teriyaki chicken, spinach, teriyaki sauce, and soy sauce. Toss everything together until combined. Tip Adding the chicken at this later stage prevents it from overcooking, keeping it tender and juicy. |
| 5 |
![]() | Taste and adjust with salt, pepper, or a drizzle of olive oil as needed. If there is excess liquid, simmer briefly to reduce it into a sauce-like consistency. Tip Leave a little liquid in the pan rather than reducing completely — the remaining moisture is what coats the noodles and creates the sauce. |

![]() | Plate and top with green onions, sesame seeds, a soft-boiled egg, shredded nori, or butter — whatever combination you like. |
How to Make Onsen Tamago (Soft-Boiled Egg)

Ingredients
- Eggs 2
- Water about 1 liter
Instructions
| 1 |
![]() | Bring a generous amount of water to a full boil in a pot. |
| 2 |
![]() | Turn off the heat. Gently lower the eggs straight from the refrigerator into the water. |
| 3 |
![]() | Leave undisturbed for 12–13 minutes. For a runnier yolk, go with 12 minutes; for a slightly firmer set, 13 minutes. Place on top of the pasta. Breaking the egg as you eat blends the yolk into the sauce, adding a creamy, carbonara-like richness. |
Tips
- Eggs can go straight from the refrigerator — no need to bring them to room temperature first. This actually makes timing easier and more consistent.
- Always turn off the heat before adding the eggs to prevent overcooking.
- Use plenty of water so the temperature stays stable once the eggs are added.
Variations

A few ways to customize this dish:
- Swap the mushrooms — maitake, eringi (king oyster), or button mushrooms all work well in place of shimeji.
- Top with a soft-boiled egg — the runny yolk blends into the soy butter sauce, adding a creamy, carbonara-like quality.
- Add milk or cream — stir in a splash toward the end for a Japanese-style cream pasta variation.
- Add chili — a pinch of dried chili flakes or togarashi gives the dish a spicier, more grown-up edge.
