BEST VEGETABLE LASAGNA WITH WHITE SAUCE RECIPES

Steps:

• Preheat oven to 375°F. Lightly coat a 9-by-13-inch baking dish with cooking spray.
• Heat oil in a medium skillet over medium-high heat. Add onion and cook, stirring often, until just tender, about 5 minutes. Add garlic and cook, stirring often, for 1 minute. Transfer the onion and garlic to a large bowl; stir in frozen vegetables and basil.
• Melt butter in the skillet over medium-high heat. Add flour and whisk to combine. Cook, whisking, for 30 seconds. Gradually add milk; cook, whisking constantly, until the mixture thickens, 2 to 3 minutes. Add Parmesan and salt; whisk until smooth. Remove from heat.
• Spread 1/2 cup of the cheese sauce on the bottom of the prepared baking dish. Layer on 3 lasagna noodles, evenly spacing the noodles crosswise in the dish. (The noodles will not cover the bottom of the dish but will expand when baking.) Top the noodles evenly with 3 cups vegetable mixture, 3/4 cup cheese sauce and 3/4 cup shredded cheese. Layer 3 lasagna noodles over the cheese; spread half the squash over the noodles and sprinkle with 3/4 cup cheese. Repeat the layers once, starting with noodles and ending with squash. Sprinkle with 3/4 cup cheese. Layer with the remaining 3 lasagna noodles; spread the remaining cheese sauce over the noodles and sprinkle with the remaining cheese.
• Lightly coat a sheet of foil with cooking spray; cover the baking dish coated-side down. Bake for 30 minutes. Uncover and bake until golden brown and bubbly, about 15 minutes more. Let stand for 15 minutes before serving. Sprinkle with basil, if desired.

Steps:

• Preheat oven to 350 degrees.
• Cook noodles according to package directions. Drain and lay flat on a sheet of aluminum foil. 
• Heat olive oil in a large skillet over medium heat. Add onions and garlic and cook for a minute. Add diced red peppers and saute for another minute or so. Add squash and mushrooms and cook for a few minutes. Pour in wine, add salt, pepper, and red pepper flakes, and stir. 
• Pour in tomatoes. Use hands to squeeze/crush them. Stir to combine and let simmer for 20 minutes or so. Stir in chopped parsley. 
• In a separate bowl, combine ricotta, eggs, Parmesan cheese, salt, and pepper. 
• To assemble, spread a little of the vegetable/tomato sauce in a lasagna pan. Layer four cooked noodles in the pan, slightly overlapping them if necessary. Spread 1/3 of the ricotta mixture on the noodles. Top the ricotta mixture with mozzarella slices. Spoon a little less than 1/3 of the veggie/sauce mixture over the mozzarella. 
• Repeat the layering two more times, ending with a large helping of vegetable sauce and a sprinkling of Parmesan. 
• Bake at 350 degrees, covered in foil, for 20 minutes, then remove foil and continue baking for 5 to 10 minutes. Remove from oven and allow to stand for 10 minutes before cutting into squares and serving.
• Serve with crusty French bread.
