Ingredients You’ll Need

• 2 tablespoons olive oil
• 2 large aubergines (about 600g), cut into 2cm cubes
• 2 large courgettes (about 400g), cut into 2cm cubes
• 2 red bell peppers, deseeded and diced
• 1 large onion, finely chopped
• 4 cloves of garlic, minced
• 800g tinned chopped tomatoes
• 3 tablespoons tomato purée
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• 500g fresh full-fat ricotta cheese
• 1 large free-range egg, lightly beaten
• 100g finely grated Parmesan cheese
• 400g fresh mozzarella cheese, torn into small pieces
• 12-15 sheets of dried egg lasagna sheets (no pre-cooking required type)
• Salt and freshly ground black pepper, to taste
• Fresh basil leaves, for garnish

Tip: Using no-boil lasagna sheets is a game-changer for maintaining those clean, distinct layers. They absorb moisture from the sauce and ricotta, expanding into perfect, tender pasta without the risk of a watery, mushy result.

How to Make Ultimate Vegetable Lasagna Recipe

1. Roast the Vegetables: Preheat your oven to 200°C (180°C fan). On a large baking tray, toss the aubergine, courgette, and red pepper cubes with 1 tablespoon of olive oil, a good pinch of salt, and black pepper. Spread them in a single, even layer. Roast for 25-30 minutes, or until the edges are deeply caramelised, the aubergine looks shrunken and golden, and the kitchen smells sweet and smoky. Give them a stir halfway through for even colour.
2. Build the Tomato Sauce: While the vegetables roast, heat the remaining 1 tablespoon of olive oil in a large, deep frying pan over a medium heat. Add the chopped onion and cook for 6-8 minutes, stirring occasionally, until it becomes soft, translucent, and smells sweet. Add the minced garlic and cook for a further minute until fragrant. Pour in the tinned tomatoes and tomato purée, then add the dried oregano and basil. Stir well, bring to a gentle simmer, and cook for 15 minutes, or until the sauce has thickened and reduced slightly, turning a deeper, richer shade of red. Season with salt and pepper.
3. Prepare the Ricotta Mixture: In a medium bowl, combine the ricotta cheese, beaten egg, and half of the grated Parmesan. Mix until smooth and creamy. The mixture should be thick and spoonable, not runny. Season with a pinch of black pepper.
4. Layer the Lasagna: Spoon a thin layer of the tomato sauce (about 4-5 tablespoons) onto the bottom of a 23x33cm baking dish. This prevents the pasta from sticking. Lay down a single layer of lasagna sheets, breaking them to fit if necessary. Spread half of the ricotta mixture over the pasta in an even layer. Scatter half of the roasted vegetables on top, followed by a third of the torn mozzarella. Repeat this process: pasta, sauce, remaining ricotta, remaining roasted vegetables, another third of the mozzarella. Finish with a final layer of pasta, the last of the tomato sauce, and the remaining mozzarella. Sprinkle the top with the reserved Parmesan cheese.
5. Rest and Bake: At this point, you can cover the dish with foil and refrigerate for up to 24 hours. When ready to bake, preheat your oven to 180°C (160°C fan). Bake the lasagna, uncovered, for 40-45 minutes. You’ll know it’s ready when the sauce is bubbling enthusiastically around the edges, the cheese on top is melted and golden brown, and the whole dish is piping hot through to the centre. For an extra-luxurious, restaurant-style finish, switch the oven to a high grill for the final 2-3 minutes to create a deeply bronzed, blistering crust.
6. The Crucial Resting Period: This is the most important step for presentation. Remove the lasagna from the oven and let it rest on a wire rack for at least 15-20 minutes. This allows the layers to set and the liquids to be reabsorbed, meaning you will get clean, defined slices that won’t collapse into a puddle on the plate. The dish will still be wonderfully hot.
7. Plate with Precision: Use a sharp, thin-bladed knife to cut the lasagna into neat squares. Using a large, flat spatula, carefully lift each portion onto a warmed plate. Wipe the edges of the plate with a clean, damp cloth for a pristine finish. Garnish each serving with a few fresh basil leaves and an extra grating of Parmesan.

Tips From My Kitchen

• Roast, Don’t Sauté: Sautéing vegetables releases their water into the pan, which can make your lasagna soggy. Roasting them in a hot, dry oven drives off that excess moisture and concentrates their flavour, giving you a far superior, meatier texture.
• Season Every Layer: This is the golden rule of layered cooking. Season the roasted vegetables with salt, season the tomato sauce, and season the ricotta mixture. Bland ricotta makes for a bland lasagna. A little salt at each stage builds a deep, savoury profile.
• Embrace the Rest: Please don’t skip the 20-minute rest after baking. I know it’s tempting to serve immediately, but this rest period is the single most effective way to guarantee those beautiful, clean slices. It allows the starches in the pasta to set and the cheese to firm up just enough.
• Use Fresh Mozzarella, Not Pre-Grated: Pre-grated mozzarella contains anti-caking agents that prevent it from melting smoothly and can make it rubbery. Tearing fresh mozzarella into small pieces ensures a wonderfully stringy, creamy, and impressive melt.
• Don’t Overload with Pasta Sheets: Using too many layers of pasta can make the dish stodgy. Stick to three distinct layers of pasta, ensuring each is just slightly covered by sauce and filling. This keeps the final texture light and the vegetable flavour prominent.
• Cool Before Cutting: For the sharpest, most professional cuts, allow the lasagna to cool for the full 20 minutes. Use a chef’s knife and wipe it clean between each cut to prevent the filling from smearing across the edges of your beautiful slices.

Equipment You’ll Need

• Large baking tray
• Large, deep frying pan
• 23x33cm baking dish
• Medium mixing bowl
• Sharp chef’s knife
• Large, flat spatula
• Wire cooling rack

Delicious Variations to Try

• Spicy Version: To add a pleasant kick of heat, stir a finely chopped red chilli (deseeded for less heat) into the onion and garlic mixture as it softens. You can also add a pinch of chilli flakes to the tomato sauce for a slow-building warmth that complements the sweet roasted vegetables beautifully.
• Vegetarian/Vegan Option: To make this recipe vegan, substitute the ricotta with a blend of 400g firm tofu, crumbled, and 3 tablespoons of nutritional yeast, blended with a squeeze of lemon juice and salt. Use a high-quality vegan mozzarella style block, torn into pieces, and ensure your lasagna sheets are egg-free. The result is surprisingly creamy and satisfying.
• Different Protein: For a heartier version, you can add a layer of cooked green lentils or a meat-free mince to the tomato sauce. If you’re not strictly vegetarian, you could also add some shredded roast chicken to the vegetable layer. My husband, who’s usually picky, asked for seconds when I added a handful of toasted pine nuts to the ricotta mixture for extra texture.

What to Serve With Ultimate Vegetable Lasagna Recipe

• A fresh, crisp green salad with a sharp lemon and garlic vinaigrette to cut through the richness.
• Some lightly charred garlic bread or focaccia for soaking up any extra sauce on the plate.
• A simple side of steamed green beans or tenderstem broccoli dressed with a little butter and flaky salt.
• For a complete Italian-inspired feast, start with a light Mediterranean Pasta Salad Recipe Cold as a refreshing first course.
