Baked Shells Recipes

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:

• Bring a large pot of water to a boil over medium heat. Salt the water, add the shells and cook for 2 to 3 minutes less than the package directions. Heads up: Remove and reserve 1 cup of cooking water just before draining.
• Meanwhile, heat a medium-sized pot or high-sided skillet over medium heat with the extra-virgin olive oil. Add the onions and garlic and saute for 3 to 4 minutes. Stir in the spinach, pulling it apart as you add it, and season with a little freshly grated nutmeg and salt, and pepper, to taste. When the spinach mixture is warmed through, transfer it to a small dish and reserve. Return the pot to the heat, add the butter and let it melt. Stir in the tomatoes and break them up with a spoon. Season with salt and pepper, to taste, add the basil leaves, and cook to thicken the sauce, about 7 to 8 minutes.
• Preheat the oven to 400 degrees F.
• Drain the pasta and return it to the hot pot. To the pasta, add the spinach, reserved pasta cooking water, ricotta cheese, and half of the Parmigiano-Reggiano. Adjust the salt and pepper, to taste, and transfer it to a baking dish. Top the pasta mixture with the tomato sauce, mozzarella, and remaining Parmigiano. Bake until the cheeses are melted and bubbly, 6 to 8 minutes. Remove the shells from the oven and serve.

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.
