Give your family lasagne a health make-over by packing it with nutritious butternut squash and spinach. Make your life that bit easier and prepare it the day before – it’ll taste better, too, as the lasagne sheets will have time to soften in the sauce.
1 Heat the oil in a large deep frying pan. Add the squash, pepper, onion, and garlic and fry over a moderate heat for 4–5 minutes or until the onion is starting to soften. Add the mushrooms, tomatoes, tomato purée, sugar, thyme, and some salt and freshly ground black pepper. Cover with a lid and simmer over a low heat for 20–30 minutes or until the vegetables are tender. Add the spinach and toss together until just wilted.
2 Meanwhile, make the white sauce. Melt the butter in a saucepan, add the flour and stir over the heat for 1 minute. Slowly whisk in the hot milk until the sauce is smooth and thick. Season with salt and freshly ground black pepper, then stir in the mustard and half the Gruyère.
3 Spoon one-third of the tomato sauce over the base of a 2.4 litre (4 pint) wide-based ovenproof dish, then spoon one-third of the white sauce on top. Arrange a single layer of lasagne over the white sauce and scatter over half the mozzarella. Spoon half the remaining tomato sauce on top, followed by half the remaining white sauce. Arrange another layer of lasagne on top and scatter over the remaining mozzarella. Spread the rest of the tomato sauce on top, followed by the rest of the white sauce, then sprinkle with the remaining Gruyère.
4 Transfer to the fridge for at least 6 hours or overnight so the lasagne starts to soften.
5 Preheat the oven to 200 ̊c (180 ̊c fan/400 ̊F/Gas 6) then bake the lasagne for 45 minutes or until golden brown and bubbling around the edges. Serve with salad and crusty bread.
