A quick, silky miso butter spaghetti with garlic and Parmesan.
Ready in 20 minutes—simple ingredients, big umami flavor.
8 oz (225 g) spaghetti
3 tbsp unsalted butter
1 tbsp olive oil
3–4 cloves garlic, minced
2–3 tbsp white (shiro) miso paste
1/2–1 cup hot reserved pasta water, as needed
1/4 cup freshly grated Parmesan, plus more to serve
Salt and freshly ground black pepper
Optional: pinch red pepper flakes, chopped parsley, 1 tsp toasted sesame oil
1. Boil spaghetti in well-salted water until al dente; reserve about 1 cup pasta water and drain.
2. Melt butter with olive oil in a large skillet over medium heat; sauté garlic 30–60 seconds until fragrant (not browned).
3. Lower heat to medium-low; whisk in miso and 1/2 cup reserved pasta water until smooth and glossy.
4. Add spaghetti; toss to coat, adding more pasta water as needed for a silky emulsion.
5. Off heat, stir in Parmesan until melted; season with pepper and salt to taste.
6. Finish with chili flakes, parsley, or a drizzle of toasted sesame oil; serve immediately.
Use white (shiro) miso for a mild, balanced sauce—darker miso will be saltier.
Add pasta water gradually to keep the sauce emulsified and glossy.
Freshly grated Parmesan melts smoother than pre-shredded.
Best enjoyed fresh; refrigerate leftovers up to 3 days and reheat gently with a splash of water or broth.
