Shepherd's Pie, Reimagined: Why Ours Has a 2-to-1 Lamb to Beef Ratio

Ask a purist and they’ll tell you a shepherd’s pie is lamb. All lamb. Use beef and it becomes a cottage pie, and the shepherd has nothing to do with it.

They’re right. And we don’t do that.

Ours is two parts lamb to one part beef, and every so often someone tells us that makes it a cottage pie. It doesn’t, and the reason is worth explaining — because it isn’t about saving money.

What lamb does, and what it doesn’t

Lamb is the whole point of a shepherd’s pie. It has a depth that beef simply hasn’t got — slightly gamey, a little sweet, and it holds up against a dark gravy without disappearing into it. Take the lamb out and you’ve made something else. Perfectly nice, but not this.

What lamb doesn’t do especially well is texture.

Minced lamb is soft. Cook it long and slow the way you should for a pie filling, and it goes further towards paste than you want. On its own it can end up uniform — one note all the way through, with nothing to chew against. The flavour’s there, but the eating is flat.

What the beef is doing

Beef is coarser. It holds its shape through a long braise, so it gives the filling something to push back with. Bite into ours and you get actual pieces rather than a smooth layer.

One part in three is enough to fix the texture without touching the flavour. Go further — half and half, say — and the lamb starts losing the argument. You’d taste beef with lamb in it. At two to one, the lamb still leads and the beef does its work in the background where nobody notices it, which is exactly where it should be.

That ratio took a while to settle on. It’s the sort of thing you only find by making it wrong a few times.

What else goes in

Peas, carrots and sweetcorn. Not a garnish and not a way of padding the meat out — the sweetcorn in particular does something specific. It’s a hit of sweetness against a savoury, ale-heavy gravy, and it stops the whole thing being one long note of rich.

Plenty of British recipes leave it out. Ours has always had it, and it’s the detail people mention.

The mash on top

A shepherd’s pie is defined by its lid, and ours is a cheesy mash rather than plain potato.

It browns properly, which plain mash struggles to do — you get that patchy golden crust with darker edges rather than a pale beige surface. And the sharpness of the cheese cuts the richness of the filling underneath, which matters when you’re eating a whole one.

If you want the longer argument about why a British pie doesn’t need pastry at all, that’s here.

Shepherd’s or cottage?

The rule most people know is: lamb makes it a shepherd’s pie, beef makes it a cottage pie. Shepherds keep sheep, hence the name. It’s a good rule and it’s roughly right.

It’s also younger than people assume. The term “cottage pie” turns up in the late 1700s, when potatoes were becoming cheap enough for ordinary households, and it just meant a meat pie with a potato lid — no particular animal implied. “Shepherd’s pie” arrives about a century later and only gradually attaches itself to lamb.

So the distinction is a convention rather than a law, and it settled long after people had been making the dish for generations. Ours is lamb-led, tastes of lamb, and is a shepherd’s pie. We’ll take the argument from anyone who wants it.

How to cook it

From frozen. 400°F, 45 to 50 minutes, until the top is properly golden and the middle reads 165°F or above.

Don’t thaw it first — the mash goes wet and the filling loosens. And don’t cover it with foil, because the steam stops the top browning, which is half of what you’re after. Full cooking guide here.

Try it

Shepherd’s Pie comes in packs of 4, 8 and 12 in the shop, and it’s in both the Union Jack Sampler and the Full Monty if you’d rather taste it alongside the others.

Collect from one of our Kansas City pickup spots, or we’ll ship it frozen anywhere in the fifty states.
