  • 300ml pot double cream
  • 100ml whole milk
  • 2 bay leaf
  • a few thyme sprigs


    This popular herb grows in Europe, especially the Mediterranean, and is a member of the mint…

  • 1 garlic clove, crushed
  • whole nutmeg, for grating
  • 1 tbsp salted butter, for greasing
  • 1 large butternut squash, peeled and thinly sliced (about 1.4kg unpeeled to give about 1.1kg prepared flesh)
  • 50g mature Double Gloucester or other hard cheese


  1. Put the cream, milk, bay, a sprig of thyme, the garlic and ¼ tsp freshly grated nutmeg in a saucepan, and bring to the boil. Take the pan off the heat and leave to infuse for 10 mins. Heat oven to 180C/160C fan/gas 4.

  2. Grease a large baking dish with the butter, then layer up the butternut squash, adding seasoning and a few thyme leaves as you go. Pour over the infused cream, leaving the bay and thyme on the top.

  3. Cover the dish with foil and bake for 30 mins. Uncover, press the squash as far under the level of the liquid as you can, then scatter with the cheese. Bake, uncovered, for 30 mins more until the butternut is tender and the whole dish is bubbling and golden. Let stand for 10 mins or so before serving.

Loved this recipe. So easy and really tasty. Could potentially mix squash and potato, maybe add a little spinach too for variation, but really good on its own, as a a side dish to a roast beef. One for my files...

Absolutely love this dish, made many times now just for us and as a dinner party side - a firm favourite and big hit with everyone. I add sliced onions in between the layers for some extra flavour, absolutely delicious.

I make this every year as a side dish to go with Christmas dinner and Boxing Day dinner. It freezes beautifully- I make two about three weeks before and cook from frozen. The whole family loves this recipe!

Made this the other evening, absolute delicious. We decided to add in a layer of leeks too which we felt only added to the dish. We have a huge glut of butternut squash this year and will definitely be making this again and again, a true winner, thank you.

Blooming lovely! The children loved it and it had all the small and taste of a potato dish but less stodgy. Easy to prepare. Biggest problem was slicing it thinly however I could of done this in the magimix with slicer attachment but I couldnt be bothered. We had ours with plain lamb chops but would work with any plain meats really. Imagine this could be a substitute for macaroni cheese for Christmas eve.

what a lovely tasty and very easy recipe... OH thought it was too sweet for him but i loved it. Served it with Roast Pork. Something different for Sunday Lunch.

Yes indeed this is truly delicious. The second time I added a layer of grilled sausages for the meat eaters and for both, with the thyme added paprika, and chilli flakes which gave it a kick. Can someone please let me know how to deal with large butternuts without using a hacksaw and cutting fingers off!!

A chef told me to put the pumpkin/butternut - no oil, nothing - in an oven preheated at 180 C. Leave it there for about 10 minutes (or longer, but beware or the outer layer will be cooked already). After that you can slice and peel the pumpkin easily. Works like a charm.
