FROZEN VEGETARIAN LASAGNA RECIPES

Steps:

• For the sauce: Put the olive oil and garlic in a medium pot over low heat. Cook the garlic, stirring occasionally at first and more often as it colors, until golden brown, about 7 minutes. Raise the heat to medium-low, add the onions and a large pinch of salt and cook, stirring occasionally, until the onions are softened, about 5 minutes. Add the carrots, and cook, stirring occasionally, until softened, about 5 minutes. Add the tomato paste and red pepper flakes, and cook, stirring constantly, for 2 minutes. Add the tomatoes, bay leaves, basil sprig, thyme and 1 teaspoon salt, raise the heat to medium and bring the sauce to a lively simmer. Continue to cook, stirring frequently, until quite thick (if you draw a spoon through the sauce, you'll see the bottom of the pot for a few seconds before the sauce fills back in), about 30 minutes. As the sauce thickens, turn the heat down a bit so the bottom doesn't scorch. Stir in the chopped basil. Let cool to room temperature before assembling the lasagna. (Makes 1 quart.)
• To assemble: Preheat the oven to 350 degrees F. Squeeze the spinach in your hands to remove as much liquid as possible. Put it in a large bowl, and stir in the ricotta, 1/2 cup of the Parmesan, the egg, 1 teaspoon salt and the nutmeg.
• Spread 3/4 cup of the tomato sauce on the bottom of a 9-by-13-inch baking dish. Lay 3 lasagna noodles across the sauce (they won't touch). Spread 3/4 cup tomato sauce on top. Dollop 1/3 of the ricotta mixture (about 1 cup) across the sauce, and use the back of a spoon to spread it (it will smush into the tomato sauce, which is fine). Scatter 1 cup of the mozzarella on top.
• Repeat the layering 2 more times. Top with the last 3 noodles, spread the last 3/4 cup tomato sauce over them and scatter the remaining 1 cup mozzarella and 1/4 cup Parmesan over the top. Spray a large piece of foil with cooking spray, and cover the baking dish.
• Bake until the noodles are soft and the cheese has melted, about 40 minutes. Remove the foil, and continue to bake until the cheese is bubbling and the lasagna is slightly browned around the edges, about 15 minutes more. Let rest 10 minutes before serving.

Steps:

• Preheat oven to 350º. Bring a large pot of salted boiling water to a boil and cook lasagna noodles until al dente. Drain.
• In a large skillet over medium heat, heat oil. Add onion and garlic and season with salt, pepper, and oregano. Stir in thawed and drained frozen spinach until completely combined.
• In a large bowl, stir together ricotta, egg, and Parmesan and season with cinnamon, salt, and pepper.
• In a large baking dish, layer 5 lasagna noodles so they’re slightly overlapping. Spoon over a thin layer of marinara and top with a layer of spinach mixture and ricotta mixture. Sprinkle with a layer of mozzarella. Repeat, ending with mozzarella.
• Cover with foil and bake 45 minutes, then remove foil and continue baking 15 minutes more.
• Let cool 10 minutes, then garnish with parsley, slice, and serve.
