One of my favorite lasagna recipes is this beetroot lasagna. It takes a bit of time if you're roasting the beets yourself but you can speed things up by using ready roasted beets.
Preheat the oven to 225˚C/450˚F. Wash the beetroot under a tap, dry and wrap each in tin foil. Roast in an ovenproof dish for about 45-60 minutes. Prick a beet with the tip of a knife to check if it is cooked. Remove from the oven and leave to cool. Slowly fry the onions in the olive oil in a frying pan until soft and translucent.
Reduce the oven temperature to 180˚C/350˚F. Melt the butter in a saucepan, add the flour and stir until a porridge forms. Leave to cook for a while, then add the whipping cream, stirring a little at a time. Leave to thicken and season with salt, pepper and nutmeg.
Once the beetroot has cooled, slice thinly and arrange the lasagna in a small casserole dish. Start with a layer of beetroot, then a scoop of onion, then a dash of sauce. Keep adding layers until everything is ready and the dish is full.
Sprinkle the lasagna with chopped rosemary and thyme, then top with chunks of goat's cheese and Parmesan cheese. Bake the beetroot lasagne for 30 minutes and serve with a handful of rucola and fresh chives.
Notes
Use ready roasted beetroots to make the beetroot lasagna even quicker.
You can store the beetroot lasagna in the fridge for 2-3 days
Reheating can be done in the oven at 150˚C (covered with foil) for about 30 minutes or in the microwave.
