How many calories in a Cornish pasty? By size, filling and crimp

A pasty is a lunch you can eat with one hand. It is warm, filling, sold at every station and service area, and it feels like a sensible meal rather than a snack: meat, potato, vegetables, all in one.

It is a meal, and a big one. A standard 227g Cornish pasty is about 602 kcal, and the bakery sizes run to 900 and beyond. As with a sausage roll or a mince pie, about two thirds of that is pastry.

The quick answer

At about 265 kcal per 100g for a traditional beef Cornish pasty.

Calories by weight

For the half you saved, the bakery pasty with no label, or the one you weighed at home.

Where the calories actually are

A standard 227g pasty, split into its two parts.

The filling is most of the weight and about a third of the calories. Potato and swede are low-density vegetables, and even the beef is only a small part of it: under the pasty's protected status the beef has to be at least 12.5% of the whole pasty, according to the Cornish Pasty Association, which in a 227g pasty is about 28g.

The pastry is the opposite. Shortcrust made with butter, lard or a mix is about 520 kcal per 100g once baked, and a pasty needs a lot of it, because the case has to be strong enough to hold the filling in one hand. The USDA entries for pasties land in the same 250 to 290 range per 100g as UK packs.

The crimp

The crimp is the thick plaited seam along the side of a Cornish pasty. It is folded pastry with no filling in it, and on a standard pasty it weighs about 25g.

The crimp is the densest part of the pasty, at roughly twice the calories per gram of the rest. There is a popular story that Cornish miners held their pasty by the crimp with dirty hands and threw it away afterwards. It is hard to verify, but it is a good habit for anyone watching the number: leaving the crimp saves about 130 kcal and costs very little of the filling.

By filling

Every common pasty filling, at the standard 227g size.

Two things stand out. The whole range is only about 136 kcal from lightest to heaviest, because the pastry is the same in all of them. And cheese and onion, the vegetarian option, is the heaviest pasty on the shelf, 79 kcal above the traditional beef one, because the filling is mostly cheese.

The vegetable pasty is the lightest, but it only saves 57 kcal. Changing the filling is a much smaller decision than changing the size.

The lunches pasties arrive in

The meal deal and fish and chips figures come from the sandwich and fish and chips breakdowns, and the crisps from the crisps breakdown. A standard pasty on its own is lighter than a meal deal. A large bakery pasty with crisps and a can is within 80 kcal of a chip shop fish supper.

Protein for the calories

A standard pasty carries roughly 13g of protein, mostly from the beef and the flour in the pastry. That is about 46 kcal for every gram of protein.

For comparison, a 100g chicken breast is about 5 kcal per gram of protein, and two eggs about 11. A pasty is a filling, warm, high-energy lunch. It is not a protein food, and it will not do much toward the target in how much protein you need per day.

UK and US words that trip up logging

• Pasty. Said with a short "a", as in "past", not like "paste". In the US the word is mostly known in Michigan's Upper Peninsula, where Cornish miners brought the recipe in the 19th century.
• Michigan pasty. Similar filling, often with rutabaga and sometimes carrot, and frequently served with gravy or ketchup. Log the gravy: 100ml is about 35 kcal.
• Swede. Rutabaga in the US. In Cornwall it is usually called turnip, which is why a Cornish recipe that says turnip means the orange root, not a white turnip.
• Skirt. The beef cut traditionally used. Same name in both markets.
• Oggy. Cornish and West Country slang for a pasty.
• Bridie. The Scottish Forfar bridie is a horseshoe-shaped meat pastry with no potato. Similar per gram, usually smaller.
• Hand pie. The nearest general US term. An empanada is the closest equivalent in shape.

Pasty mistakes to avoid

Logging "1 pasty" from a database

Database entries run from a 150g supermarket pasty to a 340g bakery one, a gap of about 500 kcal. If there is no label, a bakery pasty that fills your hand is probably 280g or more.

Choosing cheese and onion as the lighter option

It is the heaviest common pasty, at about 681 for 227g. If you want the lighter vegetarian pasty, choose the vegetable one.

Counting it as a snack

A standard pasty is about 602 kcal, close to a third of the 2,000 kcal adult reference intake. It is lunch on its own. With crisps and a can it is 874.

Ignoring the crimp

The crimp is 25g of solid pastry and about 130 kcal. Eating it out of habit is the easiest 130 kcal of the day to skip.

Three ways to keep the pasty and lose the excess

The small pasty and a side salad (about 425 kcal)

• One 150g supermarket pasty (398 kcal)
• A side salad of leaves, cucumber and tomato, no dressing (about 25 kcal)

Adds up to: about 423 kcal. A warm lunch with something fresh alongside, and lighter than the meal deal.

The standard pasty, crimp left (472 kcal)

• One 227g pasty, eaten from the filled end
• Leave the 25g crimp
• Water or a diet drink

Adds up to: about 472 kcal, the whole filling and most of the pastry.

The bakery pasty, shared (about 451 kcal)

• Half a large 340g bakery pasty (451 kcal)
• Save the other half for tomorrow, or split it

Adds up to: about 451 kcal. Large bakery pasties are usually two meals sold as one.

The verdict

A standard 227g Cornish pasty is about 602 kcal, and a large bakery one about 901. Roughly two thirds of that is pastry, and the filling barely moves the number: the whole range of fillings is within about 136 kcal.

The size is the decision that matters. A small supermarket pasty instead of a large bakery one saves about 500 kcal. Leaving the crimp saves about 130. Swapping beef for vegetable saves 57.

If you change one thing, check the weight before you choose the pasty, not the filling.

Pairs well with: the sausage calorie breakdown, the mince pie calorie breakdown, and the sandwich calorie breakdown.
