Ingredients

For the butternut squash layer

  • 2 kg butternut squash flesh cubed (about 2.5kg of squash before peeling and deseeding)
  • 2 tsp dried sage
  • 1 pinch salt and pepper

For the spinach and ricotta layer

  • 1 tbsp olive oil plus more for greasing
  • 160 g fresh spinach
  • 500 g ricotta cheese
  • 1/4 tsp ground nutmeg
  • 1 pinch salt and pepper

For the tomato layer

  • 1 tbsp olive oil
  • 1 onion
  • 2 cloves garlic
  • 800 g chopped tomatoes
  • 1 pinch salt and pepper

For the lasagne layers

  • 500 g fresh egg lasagne sheets

For the white sauce

  • 600 ml double cream
  • 100 g Parmesan cheese finely grated (or vegetarian alternative)
  • 1 pinch salt and pepper

Instructions

Make the butternut squash layer

  • Preheat the oven to 180C/350F (160C/320F fan assisted).
  • Put the butternut squash in large pan in plenty of boiling salted water. Cook for around 20 minutes until soft.
  • Drain, then chuck in the food processor with the sage and a pinch of salt of pepper. Blend until smooth.
  • Set aside in a bowl to cool and give the food processor a rinse.

Make the spinach and ricotta layer

  • Warm the olive oil in a pan over a medium heat. Add the spinach and fry for 1-2 minutes until wilted.
  • Tip the wilted spinach into a food processor along with the ricotta, nutmeg and a pinch of salt and pepper. Pulse in the food processor until smooth with green flecks. Set aside.

Make the tomato layer

  • Warm the oil in a frying pan over a medium heat. Add the onion and garlic and fry for 2-3 minutes until softening.
  • Add the chopped tomatoes and season with salt and pepper.
  • Bring to the boil, then turn down to a simmer and cook for 10 minutes until reduced by half.

Assemble the lasagne layers

  • To assemble, put half of the tomato sauce into the bottom of your greased lasagne dish, then cover with a single layer of lasagne, tearing the sheets to size if needed.
  • Next, add half the ricotta mix followed by a layer of lasagne sheets.
  • Now add half the butternut squash mix followed by another layer of lasagne sheets.
  • Repeat the pattern again: tomato sauce, lasagne, ricotta, lasagne, butternut squash, lasagne.

Make the white sauce

  • Pour your cream into a pan and add 2/3 of the Parmesan with a pinch of salt and pepper.
  • Place over a medium heat and stir for 1-2 minutes until the cheese melts. As soon the sauce is smooth, pour it over your lasagne and level off.
  • Sprinkle the remaining Parmesan over the top of the lasagne and season with black pepper.

Bake!

  • Bake for 30-45 minute or starting to brown on top.
  • Allow to cool a little before serving - it'll hold its shape better when cut.
