Stuffed Shells

Preheat oven to 375°. In a large pot of boiling salted water, cook shells, stirring occasionally, until very al dente, about 8 minutes. Drain.

In a medium bowl, mix egg yolk, garlic, ricotta, cream cheese, parsley, basil, chives, pepper, 1 c. Pecorino, and remaining 1/2 tsp. salt until well combined.

Spread bottom of a 13" x 9" baking dish with half of sauce. Fill a large piping or resealable bag with ricotta mixture. Cut a small hole in the corner. Using your non-dominant hand, hold shell and pipe in filling with your dominant hand (alternatively, fill shells with 2 spoons). Layer shells on an angle in prepared pan; it’s okay if a few overlap.

Pour remaining sauce on top. Sprinkle with mozzarella and remaining 1/2 c. Pecorino, pushing down around shell crevices to ensure coverage.

Bake stuffed shells until golden brown around the edges, 30 to 40 minutes. Let cool 10 minutes. Top with basil before serving.
