Method

  1. Heat the butter and oil in a large frying pan. Add the onions and cook slowly over a low-medium heat, stirring every now and then, for 10-15 mins until golden and soft.

  2. Meanwhile, put the garlic and half the sage in a saucepan, add the cream and milk, and heat gently, not allowing the mixture to boil, for 5 mins. Remove from the heat and set aside to cool for 10 mins, then fish out the sage and garlic. Stir in the mustard and season well.

  3. If cooking straight away, heat oven to 180C/160C fan/gas 4. Layer the pumpkin slices, onions, most of the cheese and the infused cream into a large baking dish, finishing with a layer of cream. Once you’ve used the ingredients up, scatter with the remaining cheese and put the remaining sage leaves on top. Cover the dish with foil and bake for 45 mins.

  4. Uncover the dish and increase the heat to 200C/180C fan/gas 6. Cook for a further 20-30 mins until golden brown and tender all the way through. Leave to cool for 10 mins before serving.

Delicious! Made this with half squash and half potato as I don't like things too sweet. Served as a side to steak with red wine sauce. Will definatly be making again.

Soooo tasty! I didn't bother peeling the squash (I never do, it's such a faff) and it was fine. It benefitted from sitting for ten mins as it was a bit wet when it first came out of the oven. I served it with roast pork belly and all the normal trimmings, but it's almost a meal in itself and would be nice with just a green salad for a light supper. I'll definitely be making this one again.

I am about to make this dish and freeze it for Christmas. I can see nothing to indicate at which point it can be frozen, in the dish before baking or baked first. I assume it is the latter, but would like confirmation please.

i wondered that too! I would freeze before cooking in the oven and put in dish ready to cook from frozen as to not let the pumpkin go mushy. hope this helps!
