EASY VEGETABLE LASAGNA

Steps:

• Bring a large pot of salted water to a boil, then cook lasagna noodles according to package directions. To prevent the noodles from sticking after they are drained, add two teaspoons of olive oil to the pasta water. Drain, then lay flat on a sheet of aluminum foil.
• Heat the oven to 350° Fahrenheit. Lightly oil a 13-inch by 9-inch baking dish or spray with non-stick cooking spray.
• Heat the olive oil in a wide skillet with sides over medium heat.
• Add the onion and cook, stirring occasionally, until translucent, about 5 minutes.
• Add the garlic, red pepper flakes, zucchini, yellow squash, and a pinch of salt. Cook, stirring occasionally, until the veggies are softened but still have some crunch, another 5 to 8 minutes.
• Stir in the roasted red peppers and crushed tomatoes. Bring to a low simmer and cook until the liquid has thickened and reduced by half, 5 to 8 minutes. Add the basil and season to taste with additional salt and pepper.
• While the sauce cooks, stir the ricotta cheese, eggs, and a 1/2 teaspoon of salt in a medium bowl until blended.
• Toss the parmesan cheese with the mozzarella. Set aside.
• Spoon enough vegetable mixture into the baking dish to lightly cover the bottom (about 1 cup). Arrange four noodles lengthwise and side-by-side to cover the bottom. If the noodles are short on one end, you may need to cut an extra noodle and place it into the dish to cover where the other noodles have not.
• Spread half of the ricotta cheese mixture over the noodles, then sprinkle a third of the parmesan and mozzarella cheeses on top of the ricotta. Finally, scatter a third of the vegetable sauce on top.
• Add another layer of four noodles and spread the remaining ricotta cheese over them. Scatter half of the parmesan and mozzarella cheeses over the ricotta. Spread half of the remaining vegetable sauce on top.
• Finish with a third layer of noodles and the remaining vegetable sauce. Finally, finish with the remaining cheese sprinkled all over the top.
• Cover the lasagna with aluminum foil and bake for 20 minutes; uncover, then bake for 15 minutes until the cheese is crusty around the edges.
• To make the cheese golden brown on top, slide the pan under the broiler and set to high heat for 1 to 2 minutes. Let rest 10 to 15 minutes before serving.

VEGETARIAN SPINACH AND MUSHROOM LASAGNA

Steps:

• Preheat the oven and prep the pan: Preheat the oven to 350°F. Spread the one cup of reserved tomato sauce over the bottom of a large (preferably 10- x 15-inch) casserole dish. (If your casserole dish is smaller, you may need to add another layer as you go through this step.)
• Cover with foil and bake: Pull out a sheet of aluminum foil large enough to cover the casserole dish. Spread a little olive oil over the inside of the piece of foil (the side that will have contact with the lasagna). Place the foil over the casserole dish and crimp the edges. Bake at 350°F for 25 minutes, then remove the foil and bake uncovered for an additional 25 minutes. Take the lasagna out of the oven when done and let it rest 10 minutes before cutting to serve. Once made, the lasagna will last a week in the fridge.

• Top with 3 more noodles, the remaining ricotta mixture, and 1/2 cup mozzarella (no tomato sauce in this layer).
• Top the cheese with the 3 final noodles. Spread the remaining sauce over the top.
• Sprinkle with the remaining 1 cup mozzarella cheese and remaining ¼ cup Parmesan.
• Cover the lasagna with foil (be careful not to let the foil touch the top of the cheese or it will stick-I like to stick a few toothpicks in the top of the lasagna so that they are poking up and keep the foil off of the cheese). Bake it covered for 25 minutes.
• Remove from the oven, uncover, and rotate the pan by 180. Continue cooking uncovered for 15 to 20 more minutes, until it is hot and bubbly and the cheese is beginning to have brown spots.

BEST HEALTHY VEGAN LASAGNA

Steps:

• Warm up the oven to 425 degrees Fahrenheit Start with the cashew cream:
• In a blender, combine the soaked cashews, lemon juice, water, vinegar, salt, and mustard. Blend until smooth and creamy. Be sure to capture any on the side of the blender. If needed, you can add more water but not more than a 1/4 cup. Set aside.
• Mushroom Veggie Mixture:
• To a saute pan, add the oil and warm it. To that, add in the mushrooms, carrots, onions until tender. This should take about 10 minutes.
• Add the spinach and stir gently as it wilts. Then add the garlic and cook for about 30 seconds to draw out the flavor. Quickly salt and pepper and pull from the heat. Set aside.
• Layering:
• 3/4 cup of marinara goes into the 9 x 9-inch glass baking pan, spreading carefully to ensure the bottom is fully coated.
• Place three noodles into the pan, snapping off the needed noodles to get a good fit.
• In goes 1 cup of the cashew cream, followed by half of the mushroom veggie mix.
• End the layer with 3/4 cup of marinara.
• 3 more noodles, 1 cup of cashew cream (keep remaining cashew cream for later), and the mushroom veggies' last half.
• Top with the final three noodles, 3/4 cup of the marinara smoothing it out across the top.
• Take parchment paper, spray the side that will be faced down onto the baking dish with a bit of spray oil to help prevent it from sticking.
• Cover the baking dish with the prepared parchment paper followed by a sheet of aluminum foil.
• Place the baking dish onto a baking sheet to catch any juices that may overflow, and into the oven, it goes.
• Bake for 25-30 minutes in the oven at 425 degrees Fahrenheit. You want the corners to be browning and the sauce to bubble warm.
• Remove from the oven and let it rest 15-20 minutes to set up. Add the cashew cream to the top of the cooling lasagna. The creams should spread nicely with the heat from the lasagna, but if not, add water to it to thin it out the consistency before.

VEGGIE LASAGNA

Steps:

• Preheat the oven to 350 degrees F.
• Melt the butter in a large saute pan on medium heat. Add the zucchini and yellow squash and cook until slightly tender, about 4 minutes. Add the mushrooms and cook for about 3 minutes. Add the spinach and turn off the heat. Toss to combine, letting the spinach wilt. Season with salt and pepper.
• Spray a 9-by-13-by-2-inch baking dish with cooking spray. Place 3 lasagna noodles on the bottom of the baking dish, forming 1 layer (the noodles may overlap). Layer one-third of the veggie mixture, one-third of the ricotta cheese and one-third of the Cherry Tomato Sauce in the dish, spreading each layer evenly. Top with 1/2 cup of the basil. Repeat a second time with the noodles, veggie mixture, ricotta and tomato sauce; top with the remaining 1/2 cup basil. Repeat a third time, but finish the top layer with the mozzarella.

VEGETARIAN LASAGNA

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.
