See the ingredient checklist
- 16 oz spaghetti
- 1/4 cup finely chopped flat-leaf parsley
- 1/4 cup toasted walnuts (chopped)
- 2 tablespoons olive oil
- 2 1/2 teaspoons coarsely ground black pepper
- 2 tablespoons unsalted butter
- 4 oz Parmesan (finely grated; about 1 1/2 cups)
- 3/4 teaspoon kosher salt (plus salt for the pasta water)
Keep the pasta water close
The starchy water is part of the sauce, so do not drain it away. A little extra loosens the spaghetti if the cheese thickens as you toss.
At the table
Serve straight from the pot while the sauce is fluid, with the walnut topping added at the table.
The cooking plan
How to make Parmesan & Pepper Spaghetti with Walnut-Parsley Crunch.
Bring 3 quarts of salted water to a boil in a large saucepan. Cook the spaghetti to al dente according to its package. Keep the pasta and its cooking water in the pan until the sauce is ready.
Mix the parsley and toasted walnuts in a small bowl. In a separate large pot, warm the olive oil over medium heat. Stir in the black pepper for 30–60 seconds, until fragrant, then turn off the heat.
Use tongs to move the spaghetti into the pepper oil. Add 1 1/4 cups of the hot pasta water and the butter. Stir continuously for about 1 minute.
Add the Parmesan in small additions, stirring vigorously as each addition melts. Continue for about 2 minutes, adding more pasta water if needed to make a glossy coating. Stir in the measured salt, tasting as you go.
Divide among bowls and scatter the walnut-parsley mixture over the top. Serve immediately.
