Peel and dice the sweet potato into bite sized pieces
Boil them in salted water approx. 12-15mins
Once soft, strain reserving 60-80ml water
Blend, adding a knob of butter and 50ml water – if too thick add more until smooth but not runny
Mushrooms
Slice mushrooms finely
Fry in batches in oil until soft, finish with a knob of butter in the pan *see tips*
Salt mushrooms at the end as during the process it will release more water
Bechamel
Heat butter and crushed garlic in saucepan
Add flour and stir to combine
Gradually add the milk, whisking all the time so no lumps form
Season
Preparing Lasagne

Add a layer of mushrooms and sprinkle of thyme or dried herbs
Add a few blobs of ricotta – it doesn’t need to be a perfect smooth layer

Repeat until you have 3 layers

Bake @ 180c for 20-25mins
Notes
Tips/Tricks
each component can be made in advance and cooked later in the day if doing for a dinner party
once the mushrooms are cooked they will release a little more juice/liquid so just strain this off before making the lasagne
don’t crowd the frying pan when cooking mushrooms – this will just steam them and make them soggy and release more liquid. Cook in batches and add the butter at the end to finish
this dish can be reheated and will keep for a couple days in the fridge or alternatively can be frozen too
