Roasted Vegetable Lasagne

The colder months in Stellenbosch are magical. Trees turn gold to orange to deeply auburn, then shed their colourful leaves in the streets before standing bare against the moody grey skies of the Cape.
Staying indoors brings a whole new array of cozy comforts in the shape of baked pastas, slow cooked roasts, and hearty stews. One of my go-to winter favourites have always been a classic beef lasagne al forno, but this time I’ve decided to make use of the beautiful array of seasonal vegetables for a meat-free, cheesy, creamy delight: roasted vegetable lasagne.
You can adjust the choice of vegetables to whatever you prefer – I’ve chosen butternut, broccoli, courgettes and spinach for a layered effect of yellow and green. Other great choices are tomatoes, aubergines and leeks.
I choose to make the pasta sheets from scratch, but you can also use store-bought lasagne sheets that’s been pre-cooked for a few minutes. This is a great dish to make ahead of time, just pop it into the oven 45 minutes before dinner time. It also freezes very well.


Roasted Vegetable Lasagne


Ingredients


Ingredients for roasted vegetables:

  • about 5 cups of diced vegetables of your choice
  • about 60 ml olive oil
  • 45 ml chopped fresh herbs (like thyme, rosemary, chives & basil) – or 5 ml dried herbs
  • salt & pepper for seasoning

Ingredients for bechamel sauce:

  • 125 g butter
  • 125 ml flour (1/2 cup)
  • 1 litre of milk (4 cups)
  • a pinch of ground nutmeg
  • salt & pepper for seasoning

For assembly:

  • about 250 g uncooked lasagne pasta sheets (or roughly 400 g fresh pasta sheets)
  • 250 g grated mozzarella cheese (about 2 cups)
  • 300 g ricotta cheese (about 1 cup)
  • 80 g parmesan cheese (about 1/2 cup)
  • salt & pepper for seasoning
  • some extra grated cheese for the top, a mixture of mozzarella & parmesan works best
  • a sprinkling of mixed herbs, for the top

Method


  1. Pre-heat oven to 220 C. In a large roasting tray, arrange diced vegetables, then drizzle with oil and season well with herbs, salt and pepper. Bake for 30 minutes until tender and golden brown on the edges. Remove and set aside.
  2. In a saucepan on stove top, melt butter on medium heat, then add flour and mix to form a paste. Cook for 30 seconds, stirring, then slowly add milk while stirring. Keep stirring vigorously over medium heat to form a smooth sauce. Season with nutmeg, salt & pepper, then set aside.
  3. Cook the pasta sheets in a large pot of salted boiling water until just undercooked – about 6 minutes. Drain and get ready for assembling the lasagne immediately (otherwise they might start sticking together). Please note: if you are using fresh pasta sheets, you don’t have to pre-cook them, you can go straight to assembling.
  4. In a large mixing bowl, carefully mix together the roast vegetables, mozzarella cheese, ricotta & parmesan. Season with salt and pepper.
  5. In a large deep rectangular oven dish, start layering the lasagne: start with a thin layer of white sauce, then pasta sheets, then veg mixture. Keep layering – you should repeat this about 3 times. End with a thick layer of bechamel sauce, then sprinkle with some mozzarella & parmesan, and some chopped/dried herbs. Bake at 180 C for at least 45 minutes, or until golden brown, bubbly and gooey. If the top starts to get too dark before the lasagne is cooked, cover with foil and return to the oven.
