Boil the 1.5L of stock + when boiling add in the squash slices. Cook for 4mins to just soften. Carefully drain.
Grease a 9inch square baking tin + arrange the squash in rows stacked together.
For the sauce, se a large saucepan to a medium heat + add a spoon olive oil + the butter. Melt together + add the garlic + sage. Simmer for 2mins before pouring in the cream, nutmeg, cheese, 60ml veg stock (I saved some of this from the blanching of the squash), season with salt + pepper. Let it just combine!
Pour over squash tray making sure it is evenly distributed. Season with salt, pepper + another spoon olive oil.
Bake at 200C degrees in the middle of the oven for 35mins or until its bubbling + squash is cooked through. Eat straight away. This can be prepared the day before, just keep cream mix + squash separate + combine when needed.
