Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 180°C (350°F). Lightly oil a 23x33cm (9x13-inch) baking dish and set aside. Check your gluten-free lasagna sheets packaging - some varieties need pre-cooking while others can be used dry. If needed, parboil according to package instructions, being careful not to overcook as they'll continue cooking in the oven.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>For the tomato sauce, heat 1 tablespoon of olive oil in a large saucepan over medium heat. Add the onion and sauté for 3-4 minutes until translucent. Add the garlic and cook for another minute until fragrant. Add the diced carrots and celery, cooking for 5-6 minutes until they begin to soften. The vegetables provide a flavorful base that adds natural sweetness and depth to the sauce.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Add the crushed tomatoes, tomato paste, dried herbs, salt, and pepper to the vegetable mixture. Stir well, bring to a gentle simmer, then reduce heat to low. Allow the sauce to simmer for 20-25 minutes, stirring occasionally. The slow cooking allows the flavors to meld and the sauce to thicken. Finish with balsamic vinegar for depth and brightness, then remove from heat.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>While the sauce simmers, prepare the lentil-walnut filling. In a food processor, pulse the cooked lentils and toasted walnuts until coarsely chopped but not puréed - you want to maintain some texture. Transfer to a bowl and mix in the tamari, smoked paprika, and Italian herbs. This plant-based filling provides protein and a meaty texture that beautifully mimics traditional lasagna filling.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>For the cashew béchamel, drain the soaked cashews and add them to a high-speed blender along with the plant milk, nutritional yeast, lemon juice, nutmeg, garlic powder, salt, and pepper. Blend until completely smooth and creamy, about 2-3 minutes. The cashew sauce should have a pourable consistency similar to traditional béchamel - if it's too thick, add a splash more plant milk. The nutritional yeast provides a cheesy flavor, while the cashews create richness without dairy.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Now assemble your lasagna. Spread about 120ml of tomato sauce evenly on the bottom of your prepared baking dish. Add a layer of gluten-free lasagna sheets, breaking them if needed to fit the dish without overlapping. Spread one-third of the remaining tomato sauce over the pasta, then sprinkle half the lentil-walnut mixture on top. Drizzle one-quarter of the cashew béchamel over this layer.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Add another layer of pasta sheets, followed by another third of the tomato sauce, the remaining lentil-walnut mixture, and another quarter of the béchamel. Top with a final layer of pasta sheets, the remaining tomato sauce, and pour all remaining béchamel on top, ensuring it covers the entire surface. This top layer of béchamel creates a beautiful golden crust when baked.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Cover the dish with aluminum foil, creating a slight tent so it doesn't touch the top of the lasagna. Bake for 35 minutes, then remove the foil and bake for an additional 15 minutes until the top is golden and bubbling. The initial covered baking ensures the pasta cooks through while preventing the top from burning, while the uncovered final baking creates that desirable golden finish.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Remove from the oven and let the lasagna rest for 15-20 minutes before serving. This resting period is crucial as it allows the layers to set and makes for cleaner slicing. Garnish with fresh basil leaves and a sprinkle of nutritional yeast before serving. For the perfect presentation, cut with a sharp knife and use a spatula to lift each piece cleanly.</li></ol>
