- 450 ml (2 cups) semi-skimmed milk
- ⅛ teaspoon sea salt

- ¼ teaspoon freshly grated nutmeg
For The Lasagne
- 250 g fresh egg lasagne sheets (about 6 large sheets)

Instructions
- Make the Ragu: Heat 1 tablespoon olive oil in a large sauté pan. Add the chopped onion, carrot, and celery with a pinch of salt. Cook over medium-low heat for at least 20 minutes, stirring occasionally, until the vegetables are soft. Add the garlic, fennel seeds (if using), dried oregano, and dried parsley; stir and cook for 1 minute. Add mushrooms and 1 tablespoon butter, season with salt and pepper, and cook until mushrooms are soft and have released their juices, stirring frequently. Pour in chopped tomatoes, tomato puree, and balsamic vinegar. Add vegetable stock, lentils, Henderson’s Relish, and soy sauce. Drop in bay leaves, season with salt and pepper, then reduce heat and simmer for 50-60 minutes, stirring regularly to prevent sticking.
- Make the Bechamel Sauce: In a saucepan, melt butter and stir in the flour until smooth and paste-like. Gradually pour in milk, stirring continuously to form a smooth, thick sauce. Add salt, pepper, and grated nutmeg. Set aside until needed.
- Assemble the Lasagne: Spread a small amount of ragu on the base of a casserole dish (approximately 18 x 27 cm). Place lasagne sheets on top to cover the ragu without overlapping too much. Spread half of the remaining ragu over the sheets, sprinkle some grated cheese, then pour some bechamel sauce over the cheese. Top with lasagne sheets and repeat the layering process once more. Finish with a layer of lasagne sheets, pour over the remaining bechamel sauce, and grate mozzarella, pecorino, and cheddar on top.
- Bake: Bake uncovered at 170°C (335°F) fan or 190°C (375°F) conventional oven for 25 to 30 minutes. Turn the casserole dish halfway through baking. Once the top is golden and bubbling, remove from the oven and allow to cool slightly before serving.
