Old-School Butter Pie Recipe: A Northern Classic That Costs Almost Nothing to Make

Butter pie is one of those proper old-school comfort foods that's been quietly feeding families for generations and somehow never made it into the same conversation as cottage pie or steak and ale.

Which is a shame, because for what it costs to make (almost nothing) and the effort it takes (barely any), it punches well above its weight.

If you've never had one — picture buttery, melt-in-your-mouth potatoes and onions cooked down slowly in a rich, savoury sauce, all under a golden short crust pastry lid. That's it. That's the whole pie. No meat, no fancy ingredients, no faffing. Just things you've probably already got in.

It's also the kind of recipe that genuinely doesn't need much from you. You bung it in the oven, do other things for an hour, come back, do one small bit of work, and then bung it back in again. It practically makes itself.

What You Need

• 1kg potatoes (Maris Piper or King Edward work brilliantly), peeled and thinly sliced

• 2 large white onions, peeled and thinly sliced

• A bunch of spring onions, chopped

• 100g butter (proper salted butter, not the spread)

• Salt and pepper, generously

• 2 tbsp plain flour

• 1 sheet of ready-rolled short crust pastry

• A splash of milk or beaten egg, for brushing the pastry

That's the whole list. Eight things. Most of which are sitting in your fridge or your cupboard right now.

Our Butter Pie Recipe

Slice everything thin. The thinner you slice your potatoes and onions, the better this works. A mandolin makes it a 30-second job. By hand, you're looking at roughly the thickness of a pound coin. Don't worry about being perfect — just keep them fairly even so they cook at the same rate.

Layer it all in a deep oven dish. Potatoes, onions, spring onions, salt, pepper, big chunks of butter scattered through. Build it up in layers — potato, onion, salt and pepper, butter, repeat — until everything's in. Make sure the top layer is potato so it bakes nicely.

Cover with foil. Into the oven at 180°C for 50 minutes.

Walk away. Do something else. The butter melts down, the onions soften completely, the potatoes go meltingly tender, and everything starts to smell incredible. You don't need to do anything during this stage.

Take it out and have a look. There should be a pool of buttery, savoury liquid at the bottom. Give the whole thing a good stir — it'll look a bit messy and that's fine. Taste it and check the seasoning. This is the moment to add more salt or pepper if it needs it. Trust your palate. It should taste rich and savoury, not bland.

Make a quick thickener. Spoon a few tablespoons of that buttery liquid into a small bowl. Add 2 tablespoons of flour. Whisk it together until you've got a smooth, runny paste with no lumps. Pour the thickener back into the pie dish and give it another good stir to combine.

Back into the oven, still uncovered, for 20 minutes. This thickens the sauce up beautifully and lets it bubble down into something rich and properly pie-like.

Add the pastry lid. Take the dish out, lay your sheet of short crust pastry over the top, trim it to size, and press the edges down to seal. Brush with milk or beaten egg if you want a golden finish. Make a couple of slits in the top so the steam can escape.

Back in the oven for another 20 minutes until the pastry is golden and crisp.

That's it. Pie made.

How to Serve It

Butter Pie Recipe. Serve Hot. Generous wedges. With baked beans on the side if you want it the traditional way, or with mushy peas, or just on its own with a bit of brown sauce. There are no rules with this — it's the kind of pie that goes with whatever you've got.

It's also brilliant the next day. Genuinely just as good cold, sliced like a quiche, packed into a lunchbox. If anything the flavours are even better the next day once everything's had time to settle.

A Few Things Worth Knowing

Don't be shy with the butter. The clue is in the name — butter pie. 100g sounds like a lot and it absolutely is, that's the point. It's what makes it taste like it does.

Maris Pipers or King Edwards genuinely work better than waxy potatoes here. They break down slightly and absorb the butter and seasoning properly. Charlotte or new potatoes will stay too firm and you'll lose that melting texture.

If your sauce is too thin after the first 50 minutes, add a bit more flour to the thickener. If it's too thick after the thickening stage, splash in a tiny bit of milk and stir. You're aiming for something between a stew and a gravy — coating the potatoes, not swimming around them.

Shop-bought pastry is completely fine. I'm not making my own. You don't have to either. A sheet of ready-rolled short crust does the job and means the whole pie is genuinely a one-bowl effort.

And don't skip the slits in the pastry. If steam can't escape, your pastry will go soggy on the bottom. Two or three small slits with a sharp knife is all you need.

What It Actually Tastes Like

Like a hug. There's no better way to put it.

Buttery, slightly sweet from the onions, deep and savoury, with the kind of soft melting texture that makes you slow down while you eat it. The pastry on top adds the crisp bit that turns it from a side dish into a proper pie.

It's the kind of food that costs almost nothing, takes almost no skill, and tastes like someone's grandmother made it for you on a Sunday. Which, depending on whose family recipe you're working from, is probably exactly where this kind of pie came from in the first place.

Make it once. You'll make it again.
