A pie with a difference
I think everyone loves a good pie, and this is a pie with a difference. Who'd have thought that chopping up a few sausages and combining them with butternut, leeks and peas in a creamy, cheesy sauce and covering them with crispy pastry would be so tasty?
When you've just bought an enormous butternut from the supermarket and are wondering how on earth you are going to eat it all, this recipe is exactly what you need!
And the beauty of this pie is that any leftovers are just as tasty when served cold, so you can pop a slice into a lunch box for a delicious mid-day snack!
Why I think you'll love it
- First and foremost, this sausage pie with butternuts and leeks is economical. One packet of 6 sausages will make a pie that will easily feed a family of 4.
- It's a different way of serving sausages. I know everyone loves sausages, but sometimes it's nice to ring the changes and make something different with them.
- It's quick to make. And you can make it even faster by using a roll of store-bought shortcrust pastry (although it only takes minutes to make your own).
- There are loads of vegetables in the pie, so it's almost an entire meal in one dish.
- This is a 'proper' pie with pastry top and bottom, so it's easy to slice up leftovers to pack into your lunchbox.
- And finally (and this is a brave claim) you won't find better pastry anywhere! This pastry is soft and buttery and practically melts in your mouth.
And here's how you make it!
What you will need
Equipment
For roasting the butternut you will need a baking tray
You will also need 2 mixing bowls; a small one for mixing the egg, cream and cheese custard and a larger one for making the pastry. I like to use a large earthenware mixing bowl for pastry because it has lots of room to get your hands in to mix the pastry properly.
For frying the sausages and leeks you will need a frying pan.
To bake the pie you will need a baking dish. This pie will fit comfortably into a 9" x 12" dish, and you will need a rolling pin for rolling out the pastry.
Ingredients

This recipe will make one 9" x 12" pie.
Pie filling
Sausages - I used pork and apple sausages from my local supermarket because I thought the sweetness of the apple would go well with the butternut (and it did!). You can use your own favourite brand of sausage.
Butternut - the butternut should be peeled, the seeds removed and chopped into approximately one-inch cubes. You will need sufficient butternut to arrange in a loosely packed single layer on the bottom of the pie. The butternut will be roasted in the oven until it is just tender.
Leeks - the leeks should have the top and bottom parts removed and then be rinsed under running water to remove any residual bits of dirt from the top part. Once cleaned, the leeks should be cut half down the length and then sliced into half-inch semi-circles.
Frozen peas - if you have fresh peas, by all means, use those but I find a packet of frozen peas is so convenient to use. I like to use petit pois rather than garden peas as I think they are sweeter and have more taste.
Sage and marjoram - you can use dried herbs. If you do use fresh herbs you will need approximately 3 times as much as dried, and they should be very finely chopped.
Salt and pepper - this is to your own taste and is used to season the leeks.
Olive oil - used to brown the sausages and fry the leeks. You could use sunflower oil (or vegetable oil) if you prefer.
Cream - I used double cream. You may also know this as heavy or whipping cream. You could use single cream if you prefer, or a mixture of double cream and milk. This forms the base for the custard that gets poured over the pie filling before the pie is baked.
Milk (which I totally forgot to include in the photo) - you will need a small amount of milk to mix with the cream to thin the custard down slightly.
Egg - Use a large or jumbo-sized egg if possible - otherwise you could use 2 small eggs.
Parmesan cheese - the grated parmesan cheese gets mixed with the egg and cream to form the custard.
Pastry
Flour - you need plain or all-purpose flour to make pastry. There is no need for a raising agent, so don't use self-raising flour.
Butter - this is just unsalted butter which should be cut into smallish cubes. Use it directly from the refrigerator. Butter at room temperature will combine more easily with the flour, but your pastry will be crispier if you take the time to rub fridge-cold butter into the flour.
Salt - I think a small amount of salt improves the flavour of the pastry. If you don't use salt in your diet you can leave it out.
Water - this should be ice-cold water.
What to do
Butternut
Step 1 - Prepare the raw butternut
Peel and clean the butternut and cut it into one-inch pieces. Put it into a bowl and coat it with 1 tablespoon of olive oil and a large pinch of salt. Arrange it in a single layer on a baking tray.
Step 2 - Roast the butternut
Roast the butternut for 8 to 10 minutes until it starts to brown and becomes fork-tender. Remove from the oven and set aside to cool.
Pastry
Pro tip - The pastry needs to rest for half an hour, so make the pastry while the butternut is roasting and you can make the rest of the filling while the pastry is resting.
Step 1 - Combine the ingredients
Place the flour, salt and cubed butter into a large mixing bowl.
Step 2 - Rub in the butter
Using your fingertips, rub the cold butter into the flour until the mixture resembles breadcrumbs.
Step 3 - Add the water
Add enough of the water to form a shaggy dough. You may not need all the water. At this stage, the dough should be just starting to come together.
Step 4 - Rest the dough
Press the dough together to form a smooth ball and then cover the dough with plastic wrap and place it in the refrigerator to rest for 30 minutes.
When making the dough it is important to handle it as little as possible and do not knead.
Make the filling
While the dough is resting you can make the sausage filling.
Step 1 - Sausages
Fry the sausages lightly in oil until they are starting to brown. Don't worry about cooking them all the way through, they will continue to cook in the pie. You want them to firm up so you can cut them into pieces. Remove the sausages from the pan and set aside to cool.
Step 2 - Cut the sausages into pieces
Allow the sausages to cool and cut them in half lengthwise, and then cut each half into three or four pieces.
Step 3 - Fry the leeks
Add the leeks to the same pan along with the salt and pepper and herbs and fry them over a moderate heat until they start to soften. Add another splash of oil if necessary. Stir the leeks until they are soft.
Step 4 - Add the other ingredients
Add the peas and sausages to the leeks.
Assemble the pie
Step 1 - Divide the pastry
Cut the pastry into 2 pieces, approximately 2 thirds in one piece and 1 third in the other.
Step 2 - Line the pie dish
Roll the larger piece of pastry out to approximately 1-eighths of an inch in thickness and use it to line your baking dish.
Step 3 - Add the butternut
Arrange the cooked butternut in a single layer on the bottom of the pastry case.
Step 4 - Add the sausage and leeks
Arrange the sausage and leek mixture on top.
Step 5 - Mix the custard
Combine the cream, milk and egg in a small bowl and then stir in the cheese.
Step 6 - Add the egg and cheese mixture
Pour the egg and cheese mixture evenly over the pie.
Step 7 - Add the pastry lid
Roll out the smaller piece of pastry and use it to form a lid on top of the pie. Trim the edges of the pastry and use a fork to seal the edges. Prick holes on top of the pie to allow the steam to escape as it cooks. Brush the top of the pastry with lightly beaten egg.
Step 8 - Bake
Bake in a preheated oven (190C / 375F) for 25 to 30 minutes until the pastry is cooked and golden.

Butternut, leek and sausage pie FAQ
You can freeze the pie once it has been assembled (before it is baked) and store it for up to 3 months.
If you intend to make this pie for the freezer I would suggest assembling it in a disposable aluminium container so you don't have to keep your casserole dish in the freezer.
To use, bake from frozen but add 6 to 8 minutes to the cooking time. If the pastry seems to be browning too much due to the increased cooking time, cover it with a sheet of tin foil.
You can also freeze leftovers. Wrap them in tin foil and place them into a large freezer bag. Allow to defrost and then reheat in a hot oven for 7 to 8 minutes until piping hot.
Leftovers can be safely stored in the refrigerator, in a covered container, for up to 3 days.
No, you could use pieces of pumpkin in place of the butternut. The method of roasting them remains the same.
I like to serve a helping of freshly steamed vegetables with the pie. You may also like to smother it in your favourite gravy!
Chilling the pastry in the refrigerator allows the butter to harden resulting in a crispier pastry, with less chance of the pastry 'shrinking' as it bakes.
