Updated 12 September 2026 · price from a third party listing
At 372 kcal, Large Signature Fries is the heaviest single item on KFC’s Sides list. Updated 12 September 2026.
The £2.29 figure came from a third party listing rather than from KFC, which means it may reflect a delivery menu. Delivery prices sit above in restaurant prices before any fee is added, so treat this as the ceiling rather than the till price.

Everything You Need to Know About KFC Large Signature Fries
How to order Large Signature Fries at KFC
You can order Large Signature Fries at the counter, at a KFC kiosk, or in the KFC app for collection or delivery. It is filed under Sides. Availability is set per branch, so a smaller site may not carry it at all.
KFC Large Signature Fries price in 2026
The KFC Large Signature Fries price in 2026 is £2.29 on the figures we hold. The figure came from a third party listing rather than from KFC, so read it as a ceiling. Within the Sides section that puts it 4th of 5 on price. Expect more at airport, motorway and station branches than on a high street, and more again through a delivery app.
Allergens declared
KFC lists none of the 14 allergens UK law regulates as an ingredient of this item. It does list celery, cereals containing gluten, milk and soya as a possible trace, meaning KFC cannot rule those out. A declaration covers the recipe and not the kitchen, and every one of these chains prepares food in shared fryers and on shared surfaces. For a severe allergy the only reliable check is asking staff on the day.
Where it sits on price
3 items cost less than this one in the Sides section and 1 costs more, out of 5 we hold a price for. The closest thing to it on price is Side Salad at £2.29, so those two are the real comparison when you are deciding.
A lighter choice in the same section
Large Creamy Mash sits in the same part of the menu at 248 kcal, which is 124 fewer than this for £1.59–£2.29. That swap is the single biggest change available inside this section, and it needs no substitution or special request at the counter.
What 372 kcal means here
372 kcal is well above the Sides average. That is a normal single course for most people, and it leaves room for a side. The 2,000 kcal figure printed on UK menus is a reference intake for an average adult, not a target, and it is the number these percentages are worked against.
Pro Tips for Ordering Large Signature Fries
The side is where a meal grows
Sides are priced low enough to feel incidental and carry enough energy to change a meal's total. The smaller size, or one shared between two people, keeps the main choice intact. KFC lists sides separately from meals for exactly this reason.
Finding it near you
We list 890 KFC branches across 4 of the four UK nations, with the Northern Ireland postcode area holding the most at 32. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The KFC app confirms it in seconds.
Protein for the calories
It gives 1.2g of protein per 100 kcal, against a menu average of 3.8g across everything we hold for KFC. That is a weak ratio for this menu, which matters more than the raw protein figure when you are comparing two items of different sizes. On raw protein it ranks 3rd of 8 in its section.
