Ingredients
- 1 cup grated Parmigiano-Reggiano or Pecorino Romano (2 ounces)
- 1/2 stick unsalted butter, softened
- 2/3 cup all-purpose flour
- 1 large egg yolk
- 1 teaspoon coarsely ground black pepper, divided
Directions
- Pulse cheese with butter in a food processor until combined. Add flour, yolk, and 1/2 teaspoon pepper, then pulse until a dough forms. Roll into a 6-inch log (1 1/2 inches thick). Wrap in parchment paper and chill until firm, at least 1 hour.
- Preheat oven to 350°F with rack in middle.
- Cut log into 1/4-inch-thick slices and arrange 1 inch apart on a baking sheet. Sprinkle with remaining 1/2 teaspoon pepper. Bake until golden, about 15 minutes. Cool to warm on a rack.
