Stuffed Shells with Marinara

Preparation

1. Step 1

   Preheat oven to 375°F. Cook shells in a large pot of boiling salted water, stirring occasionally, until very al dente; drain. Run under cold water to stop the cooking and drain again.

   Step 2

   Lightly whisk egg yolks and egg in a large bowl. Stir in ricotta, Parmesan, parsley, and 1 1/2 cups mozzarella; season with salt and pepper. Transfer filling to a large resealable plastic bag.

   Step 3

   Spread 1 1/2 cups marinara sauce in a 13x9" baking dish. Snip off 1 end of plastic bag and, working one at a time, squeeze filling into shells, arranging them in a single layer in baking dish as you go. Top with remaining 1 1/2 cups marinara sauce and remaining mozzarella. Cover pan tightly with foil and bake shells until sauce is bubbling throughout, 35–40 minutes. Let rest 5 minutes.

   Step 4

   Carefully move rack to top of oven and heat broiler. Uncover pasta and broil until lightly browned on top, about 2 minutes. Sprinkle with oregano and more Parmesan and drizzle with oil.
