HOW DO YOU MAKE SPINACH LASAGNA RECIPES

Steps:

• Preheat the oven to 375 degrees F.
• Bring a large pot of lightly salted water to a boil and cook the lasagna noodles for 10 to 12 minutes. Drain the noodles and drizzle them with 1 tablespoon of the olive oil, and then set the noodles aside for later use. (If you are using no-boil noodles, skip this step.)
• Heat the remaining 2 tablespoons olive oil in a large skillet set over medium heat and cook the shallots until softened and translucent, 4 to 5 minutes. Add in the garlic and zucchini, and cook for 1 minute. Stir in the spinach and cook until wilted, 2 to 4 minutes.
• In a large bowl, stir to combine the ricotta, Parmesan, salt, pepper and egg, and set aside for a later use.
• To assemble the lasagna, spoon 1/2 cup of the Chunky Marinara Sauce into the bottom of a 9-by-13-inch baking dish. Top with 5 noodles, slightly overlapping. Spread one-third of the ricotta mixture over the noodles, then add one-third of the cooked zucchini and spinach, evenly distributing over the ricotta. Top with 2 cups of the mozzarella, then top with 1 cup of the sauce. Repeat the layering two more times, ending with a layer of noodles and a sprinkle of mozzarella.
• Cover with foil and bake for 40 minutes.
• Remove the foil and continue to bake until bubbling and cooked through, 10 to 20 minutes more. Cool for 10 to 15 minutes before serving.
• Heat the olive oil in a large saucepan set over medium heat and add the carrots, celery and onions, and cook until soft and translucent, stirring occasionally, 8 to 10 minutes.
• Stir in the garlic and cook for 1 minute, then stir in the oregano, chile flakes, tomato puree, chopped tomatoes and their juices, basil leaves and some salt and pepper. Bring to a simmer and cook until the sauce has thickened, about 30 minutes.

Steps:

• If you're using dried pasta, bring a large pot of salted water to a boil. If you're using fresh pasta sheets, cut them into long wide noodles approximately 3 inches by 13 inches, or a size that will fit into your lasagna dish. Cook the noodles (6 at a time for dried noodles) until they are tender but still underdone (they will finish cooking as the lasagna bakes); fresh pasta will take only a minute. Drain and then lay the noodles flat on a towel so they won't stick.
• Heat the oven to 400 degrees. Grease a rectangular baking dish with the olive oil, add a large dollop of tomato sauce and spread it around. Put a layer of noodles (use four) in the dish, trimming any overhanging edges; top with a layer of tomato sauce, one-third of the spinach, and one-fourth of the ricotta (use your fingers to spread it evenly), the mozzarella and the Parmesan. Season with salt and pepper if desired.
• Repeat the layers twice, and top with the remaining noodles, tomato sauce, ricotta, mozzarella and Parmesan; the top should be covered with cheese; add more ricotta and Parmesan as needed. (The lasagna may be made ahead to this point, wrapped tightly and refrigerated for up to a day or frozen. Bring to room temperature before proceeding.)
• Bake until the lasagna is bubbling and the cheese is melted and lightly browned on top, about 30 minutes. Remove from the oven and let rest a few minutes before serving, or cool completely, cover well, and refrigerate for up to 3 days, or freeze.
