Prepare the Impossible "Ragù": Heat olive oil in a large pan. Sauté onion until softened, then add garlic and cook for another minute. Add Impossible Ground and cook, breaking it up with a spoon, until browned. Stir in crushed tomatoes, 4 oz. of the marinara sauce, red wine, oregano, thyme, salt, and pepper. Bring to a simmer and cook for 15 minutes, allowing the flavors to meld.
Craft the Cashew Cream Bechamel: Blend soaked cashews, plant-based milk, nutritional yeast, olive oil, Dijon mustard, garlic, salt, and pepper until smooth and creamy.
Whip Up the Dairy-Free Ricotta: Crumble tofu into a food processor. Add nutritional yeast, olive oil, lemon juice, oregano, salt, and pepper. Blend until smooth and fluffy.
Assemble the Lasagna Masterpiece: Preheat oven to 375°F (190°C). Grease a 9x13 baking dish. Spread a thin layer of "ragù" on the bottom. Top with zucchini ribbons, lasagna noodles, then dollop with cashew cream sauce and dairy-free ricotta. Repeat, layering "ragù", zucchini, noodles, cashew cream, and ricotta until the dish is full, ending with a layer of marinara sauce and sprinkle of preferred seasoning and herbs.
Bake to Perfection: Cover the lasagna with foil and bake for 30 minutes. Remove foil and bake for another 15-20 minutes, or until bubbly and golden brown. Let cool slightly before serving.
The Grand Finale: Garnish with fresh basil or mint leaves and prepare for a standing ovation! Every bite of this plant-powered lasagna is a testament to the magic of creative ingredients and delicious ingenuity. It's a dish that will leave everyone, vegan or not, wanting more.
