Entrees

Ingredients

1 pound pasta

Salt and coarsely ground pepper

1 tablespoon unsalted butter

2 cups caramelized onions

1 ½ ounces shredded Pecorino Romano cheese (3/4 cup), plus extra for serving

¼ cup chopped fresh parsley

1 tablespoon white wine vinegar

Directions

Bring 4 quarts water to boil in large pot. Add pasta and 1 tablespoon salt and cook, stirring occasionally, until al dente. Reserve 1 1/2 cups cooking water, then drain pasta and return it to pot.

While pasta cooks, melt butter in 10-inch skillet over medium heat. Add 1 tablespoon pepper and cook until fragrant, about 1 minute. Add onions and 1/2 teaspoon salt and cook, stirring occasionally, until onions are warmed through, about 4 minutes.

Add Pecorino, parsley, vinegar, onions, and 1 cup reserved cooking water to pasta and stir to combine. Season with salt and pepper to taste. Serve, adjusting consistency with remaining reserved cooking water as needed and passing extra Pecorino separately.
