I take zero credit for this recipe - it's thanks to my friend Flo, who's a whizz at finding ways to use up squash :) I baked them for a cake sale and they got rave reviews, so this is to help out those who wanted the recipe.
1 large butternut squash (1.5kg), halved and de-seeded
1 onion, finely chopped
2-3 cloves garlic, to taste, finely chopped or crushed
small handful fresh sage leaves, finely chopped
125g mascarpone
1 medium egg plus another to brush on pastry
salt and pepper
500g pack puff pastry
oil for roasting and frying the onion
Oil the cut surfaces of the squash and roast at 150°C until tender. Allow to cool while you sweat off the onion and add the garlic, sage and seasoning.
Peel the cooled squash (I find it easier this way), mash half to two-thirds of it, and chop the rest.
Mix , taste and season as needed. If your squash was quite wet you might not need all the egg - a softer mix is harder to work with. You could add breadcrumbs if it's too sloppy.
Roll out the pastry to the desired size (I did it in four lots to keep things manageable) - you need to make a longish sausage that you can then cut into individual rolls. If the mixture is too soft then it's this bit will be difficult. As you can see from the pic, my rolls were full and quite narrow, and I think wider would have been better. You could also try cutting the pastry and then adding the filling.
Use beaten egg to seal the pastry and glaze the top, then bake at 200-220°C for 20-25 mins until golden brown.
Any leftover mix can be cooked in dollops on a non-stick baking mat and used a bit like felafel, e.g. with salad, in a pitta, etc. If it's quite soft it makes an awesome toastie filling!
