Instructions

Step 1: Prepare the Vegetable Filling

  • Heat the olive oil in a large frying pan over medium heat.
  • Sauté the onion, garlic, carrot, and celery until softened, about 5 minutes.
  • Add the courgette and mushrooms, cooking for another 5–7 minutes.
  • Stir in the chopped tomatoes, tomato purée, oregano, salt, and pepper.
  • Simmer for 15 minutes until the mixture thickens slightly.
  • Add the spinach and cook until wilted.

Step 2: Make the Béchamel Sauce

  • In a saucepan, melt the butter over medium heat. Stir in the flour to form a roux and cook for 1–2 minutes.
  • Gradually whisk in the milk, ensuring there are no lumps. Cook until the sauce thickens.
  • Add a pinch of nutmeg and the grated cheddar cheese. Stir until smooth.

Step 3: Assemble the Lasagne

  • Preheat your oven to 200°C (180°C fan) or 400°F.
  • Spread a layer of the vegetable filling on the bottom of a baking dish.
  • Cover with a layer of lasagne sheets, followed by a layer of béchamel sauce.
  • Repeat the layers, finishing with a layer of béchamel on top.

Step 4: Add the Cheese Topping

  • Sprinkle the mozzarella and Parmesan cheese evenly over the top.

Step 5: Bake the Lasagne

  • Cover the dish with foil and bake for 30 minutes.
  • Remove the foil and bake for an additional 15 minutes, or until the top is golden and bubbling.

Step 6: Rest and Serve

  • Let the lasagne rest for 10 minutes before slicing and serving.
