Stuffed Shells Recipe 455

Steps:

• For the marinara sauce: Heat the oil in a medium heavy-bottomed pot over medium heat. Add the onions and cook, stirring occasionally, until very soft, 8 to 10 minutes. Add the garlic and red pepper flakes, if using, and continue to cook, stirring occasionally, until the garlic has softened but not browned, about 3 minutes. Stir in the tomato paste and cook for 2 minutes. Add the crushed tomatoes. Season with salt and pepper and bring to a simmer. Reduce the heat, add the basil and dried oregano, partially cover and simmer gently, stirring occasionally, until the sauce is thickened, about 45 minutes.
• Remove the basil sprig. If the sauce is still too chunky, mash the larger chunks of tomato with a potato masher. Season with salt and pepper. Let cool.
• For the shells and filling: Bring a large pot of salted water to a boil over high heat. Add the dried pasta shells cook, stirring occasionally, until softened slightly but not cooked. (The pasta shells should flexible enough to be filled but remain very al dente; they will continue to cook during baking.) Drain, then run under cold water to stop cooking. Drain well again.
• Preheat the oven to 375 degrees F.
• Mix together the ricotta, mozzarella, Parmigiano-Reggiano, parsley and egg in a large bowl until well combined and uniform. Season liberally with salt and pepper. Transfer the filling to a large disposable pastry bag or large resealable plastic bag (or use a spoon for filling directly from the bowl).
• Spread 2 1/2 cups of the marinara sauce in a 13-by-9-inch baking dish. Snip off the end of the pastry bag and squeeze the filling into the shells one at a time. Arrange the shells open-side up in a tight single layer in the baking dish as you fill them. Top with the remaining marinara sauce. Cover the pan tightly with foil and bake the shells until the sauce is bubbling throughout and the filling is heated through, about 35 minutes.
• Remove the foil from the pan and continue to bake for 10 more minutes to reduce the sauce. Let cool slightly before serving. Top with grated Parmigiano-Reggiano.

Steps:

• Preheat oven to 350 degrees F (175 degrees C).
• Bring a large pot of lightly salted water to a boil. Add pasta and cook for 8 to 10 minutes or until al dente; drain.
• In a large bowl, mix eggs, ricotta, half the mozzarella, half the Parmesan, parsley, salt and pepper until well combined. Stuff cooked shells with ricotta mixture and place in a 9x13 inch baking dish.
• In a medium bowl, stir together pasta sauce, mushrooms and reserved mozzarella and Parmesan. Pour over stuffed shells.
• Bake in preheated oven 45 to 60 minutes, until edges are bubbly and shells are slightly set.

Steps:

• Make the sauce: Heat the olive oil in a large wide pot over medium-high heat. Add the garlic and cook until golden brown, about 2 minutes. Add the tomatoes, oregano, red pepper flakes, 1/2 teaspoon salt and a few grinds of pepper. Bring to a boil, then reduce the heat to a simmer. Cook, stirring, until thickened, 15 to 20 minutes; season with salt. (You should have about 4 heaping cups of sauce.)
• Make the stuffed shells: Preheat the oven to 375˚ F. Bring a large pot of salted water to a boil. Add the pasta shells and cook as the label directs for baking, about 9 minutes. Rinse under cold water to stop the cooking. Spread out on a baking sheet.
• Heat the olive oil in a large skillet over medium-high heat. Add the spinach and cook, tossing occasionally, until wilted, 2 to 3 minutes. Remove to a large plate lined with a kitchen towel. Squeeze to remove any excess liquid, then finely chop.
• Put the spinach in a large bowl and add the ricotta, mozzarella, parsley, Parmesan, lemon zest, beaten egg, 1/2 teaspoon salt and 1 teaspoon pepper. Stir until combined.
• To assemble, spread about half of the sauce in the bottom of a 10-by-14-inch baking dish. Evenly fill the shells with the spinach-ricotta mixture using a spoon, or pipe it in using a pastry bag. Arrange the shells side by side, open-side up, in the baking dish on top of the sauce, then top with the remaining sauce.
• Cover the dish with foil and bake until heated through and the sauce is simmering around the edges, about 30 minutes. Remove the foil and bake until any shells or cheese poking through the sauce are lightly browned in spots, about 10 more minutes. Let sit 10 minutes. Top with more Parmesan and red pepper flakes.

Steps:

• Make the sauce: In a large Dutch oven or pot, heat the olive oil over medium. Add the onion and a pinch of salt and cook, stirring occasionally, until softened, 5 to 7 minutes. Add the garlic and tomato paste and cook, stirring frequently, until the paste turns one shade darker, about 2 minutes. Stir in the tomato purée, season with salt, then bring to a simmer. Cover halfway to reduce splattering, and cook, stirring occasionally, until the sauce has thickened slightly, 20 to 30 minutes.
• Heat the oven to 375 degrees. Bring a large pot of salted water to a boil.
• Make the filling: In a medium bowl, combine the ricotta with 1 1/2 cups mozzarella, 1 cup Parmesan and the egg yolks. Grate the garlic directly into the bowl, then season with 1 teaspoon salt and 1/2 teaspoon pepper. Stir to combine, then set aside.
• Add the shells to the boiling water and cook until just shy of al dente. (You'll want to cook the shells about 2 minutes less than the minimum time listed on the package, as the shells will continue to cook in the oven in Step 5.) Reserve 1/2 cup pasta water, then drain the pasta and rinse it under cold water to cool. Count out 24 shells. (You will have cooked off more shells than will fit in the dish; that's insurance in case any rip. Reserve extras for another use.)
• Stir the pasta water into the sauce, then add half the sauce to a 3-quart/9-by-13-inch baking dish and spread it in an even layer. Spoon about 2 tablespoons filling into each of the 24 shells, lining up the stuffed shells in the dish as you go. Spoon the remaining sauce over the shells, then sprinkle with the remaining 1 cup mozzarella and 1 cup Parmesan.
• Cover the dish tightly with foil and bake for 30 minutes. Remove the foil and bake, uncovered, until the cheese is melted and the sauce is bubbling, 15 to 20 minutes. (If you'd like to brown the cheese, you can broil for a few minutes.) Let sit 5 minutes, then serve.
