Recipe Ingredients

Pasta Water: Always reserve some pasta water before draining! The starchy water helps thicken and bind the sauce to the noodles, creating a silky smooth finish. While I typically salt my pasta water, for this recipe I didn’t, as the salted butter and white miso provide plenty of saltiness.
Salted Butter: Feel free to use unsalted butter if you prefer. If using unsalted butter, I recommend salting your pasta water and tasting the pasta before serving. Add a sprinkle of salt to taste if needed.
Japanese Chili Oil: I prefer using S&B La-Yu, a Japanese chili oil that adds great flavor without being too overpowering or spicy. It perfectly complements the savory miso, enhancing the dish with a subtle heat.
