Five-Ingredient Creamy Miso Pasta

Bring a large pot of salted water to a boil. Add the pasta and cook, stirring occasionally, until al dente. Reserve 1 1/2 cups pasta water, then drain the pasta.

Add the butter, miso and 1 1/4 cups pasta water to the pot and whisk over medium heat until miso breaks down and liquid is uniform, 1 to 2 minutes. Add the pasta and Parmesan and cook, stirring vigorously with tongs until cheese is melted and sauce emulsifies. (The key word here is “vigorously.” To achieve a silky smooth pasta instead of a gloppy one, put your cacio e pepe skills to work.)

Divide among shallow bowls and sprinkle with nori or furikake, if using.
