For 4
500g of butternut squash (peeled, cut up into chunks and roasted in the oven with some sage,tiny bit of garlic and some oil for about 20 mins until soft). I usually do this beforehand, it will keep in the fridge overnight etc
Put about 300g of macaroni pasta on to cook in salted boiling water
For the sauce
Melt 40g butter and add 40g of flour.
Mix to a paste on a low heat with a hand whisk. Make sure all of the flour is mixed into the butter. Then add 600ml of milk and heat up on a fairly low heat.
Use a hand whisk while it is heating up and keep whisking every now and then. Eventually you will get a thickened white sauce. Add most of 175g of grated cheddar (keep a bit back for the topping). Take off the heat
When the pasta is cooked, drain and mix it with the cheese sauce and also with the cooked butternut squash pieces. Do this quickly.
Don't let the pasta get cold and sticky.
Then pour it all into an oven dish and sprinkle the leftover grated cheese on the top.
Put under the grill for 5- 10 minutes until the cheese on the top has melted and it is all bubbling
This is DS's favourite meal of all time. I only make it every 4-5 weeks as it is pretty calorific and he always eats about 3 plates of it
