Cacio E Pepe

1 . Stage

In a large pot of boiling salted water, cook pasta, stirring occasionally, until very al dente, about 3 minutes less than package directions. Reserve 2/3 cup pasta water before draining.

2 . Stage

In a large skillet over medium heat, heat oil and 1 tablespoon butter until butter is melted. Add a generous amount of pepper and toast, stirring frequently, until fragrant, about 1 minute.

3 . Stage

Add 1/2 cup reserved pasta water and bring to simmer. Whisk in remaining 1 tablespoon butter. Using tongs, add pasta, tossing into butter mixture.

4 . Stage

Remove skillet from heat. Gradually add Parmesan and pecorino and toss constantly until cheese is melty. (If sauce is too thick or clumping, loosen with more pasta water.)

5 . Stage

Divide pasta between bowls. Top with more Parmesan and pecorino.
