Ingredients

For the tomato sauce:

• 2 tablespoons olive oil
• 1 large onion, finely chopped
• 2 garlic cloves, minced
• 2 medium carrots, diced
• 2 celery stalks, diced
• 1 zucchini, diced
• 1 eggplant, diced
• 400g canned chopped tomatoes
• 2 tablespoons tomato purée
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• Salt and black pepper to taste
• 200ml vegetable stock

For the vegetables:

• 200g spinach, fresh or frozen (thawed and drained)
• 200g mushrooms, sliced
• 1 red bell pepper, diced

For the béchamel sauce:

• 50g butter
• 50g plain flour
• 500ml milk
• 100g grated cheddar cheese
• Pinch of nutmeg
• Salt and pepper to taste

Additional layers:

• 12-15 lasagne sheets (oven-ready)
• 200g mozzarella, sliced or grated
• 50g Parmesan, grated
• Fresh basil leaves for garnish (optional)

Preparing the Tomato Vegetable Sauce

1. Start with the tomato sauce base. Heat olive oil in a large pan over medium heat. Add the chopped onion. Cook for 5 minutes until soft. Stir in minced garlic. Cook for 1 minute more.
2. Add carrots, celery, zucchini, eggplant, and red bell pepper. Sauté for 8-10 minutes. Vegetables should soften but keep some bite. Stir in tomato purée. Cook for 2 minutes.
3. Pour in canned tomatoes and vegetable stock. Add oregano and basil. Season with salt and pepper. Bring to a simmer. Reduce heat. Let it cook for 20 minutes. Stir occasionally. The sauce thickens as it reduces.
4. In another pan, sauté sliced mushrooms in a little oil for 5 minutes until golden. Add spinach. Wilt for 2 minutes. Drain excess liquid. Mix these into the tomato sauce. Taste and adjust seasoning. Set aside.

This sauce forms the heart of your veg lasagne. Its chunky vegetables provide texture and nutrition. Tomatoes offer acidity to balance creamy layers.

Making the Creamy Béchamel Sauce

1. Melt butter in a saucepan over medium heat. Add plain flour. Whisk constantly for 1-2 minutes. This creates a roux. It should turn pale gold, not brown.
2. Gradually pour in milk. Whisk vigorously to avoid lumps. Keep stirring as the sauce thickens. This takes 5-7 minutes. Once bubbling gently, remove from heat.
3. Stir in 75g grated cheddar cheese until melted. Add nutmeg, salt, and pepper. The sauce should coat the back of a spoon. If too thick, add a splash of milk. If too thin, simmer longer.

Cheese in béchamel boosts flavor. Nutmeg adds subtle warmth. This sauce glues the lasagne together.

Assembling the Veg Lasagne

1. Preheat oven to 180°C (350°F). Use a 20x30cm baking dish. Spread 1 cup tomato sauce on the bottom. This prevents sticking.
2. Layer 3-4 lasagne sheets over the sauce. They may overlap slightly. Add one-third of the remaining tomato sauce. Spoon over one-third of the béchamel. Scatter some sliced mozzarella.
3. Repeat layers twice more. Finish with lasagne sheets. Top with remaining béchamel. Sprinkle Parmesan and rest of mozzarella.
4. Cover with foil. Bake for 30 minutes. Remove foil. Bake 15 minutes more until golden and bubbling. Let rest 10 minutes before cutting. This sets the layers.

Assembly is key for even cooking. Sauce-to-pasta ratio matters. Too much sauce makes it soupy. Too little dries it out.

Baking and Serving Tips

• Resting after baking is crucial. It firms up slices. Serve with garlic bread and green salad. A sprinkle of fresh basil elevates it.
• For make-ahead, assemble lasagne up to 24 hours ahead. Cover and refrigerate. Add 10 minutes to baking time if cold.
• Freeze unbaked lasagne. Wrap tightly. Thaw overnight in fridge before baking. It freezes well for up to 3 months.
• Vary vegetables by season. Swap eggplant for butternut squash in fall. Add lentils for protein boost.
• Oven temperatures vary. Check doneness by inserting a knife. It should slide easily through pasta.

This veg lasagne rivals meat versions. Vegetables mimic ragù texture. It’s lower in calories yet satisfying.
