Low Calorie Spinach Ricotta Stuffed Shells Recipe 435

Steps:

• Cook shells according to package directions; rinse under cold water, drain and pat dry. Meanwhile, heat oil in a large saucepan over medium heat. Add onion and cook until browned, about 5 minutes. Add tomatoes, sugar and season with salt and pepper to taste. Let simmer until sauce is slightly thickened, about 10 minutes. Set aside. Preheat the oven to 375 degrees. Coat a 9 x 9 inch baking dish with cooking spray. Combine spinach, both cheeses, egg white and 1/4 teaspoon of each salt and pepper in a large bowl. Spoon half the tomato sauce into prepared dish and mix. Stuff each shell with 1 heaping tablespoon and arrange stuffed shells in baking dish. Spoon remaining sauce over shells and cover with aluminum foil. Bake until pasta is cooked through and sauce begins to bubble, about 30 minutes. Let sit 5 to 10 minutes before serving.

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:

• Bring a large pot of water to a boil and salt generously. Fill a bowl with ice water. Blanch the spinach for no more than 20 seconds, just until wilted, and transfer to the ice water, then drain. Squeeze out excess water. Bring the water in the pot back to a boil and add the pasta shells. Cook al dente, about 10 minutes, and drain and toss with the olive oil. Set aside.
• Turn on a food processor fitted with the steel blade and drop in the garlic. When the garlic is chopped and adhering to the sides of the bowl, stop the machine and scrape down the sides of the bowl. Add the spinach and pulse to chop finely. Add the ricotta and the egg and process until well blended. Add 1/3 cup of the Parmesan, the chives, and salt and pepper to taste. Pulse until well blended.
• Preheat the oven to 350 degrees. Oil a large baking dish or two 2-quart dishes. The shells should fit into the dish in one layer. Fill each shell with a scant tablespoon of the filling. Arrange in a single layer in the baking dish. Top with the tomato sauce and cover the dish with foil.
• Bake 30 minutes in the preheated oven. Remove from the heat, sprinkle on the remaining Parmesan, and serve.
