Fluffy on the inside and crispy on the outside, our fries are cut from whole potatoes. That's why they're so delicious.
No verifiable price exists for it. McDonald's sets prices branch by branch and publishes no national list, so the only accurate number is the one on the board in front of you or in the app.
Allergens McDonald's declares
None of the 14 regulated allergens is listed as an ingredient.

Everything You Need to Know About McDonald's Fries
How to order McDonald's Fries at McDonald's
You can order McDonald's Fries at the counter, at a McDonald's kiosk, or in the McDonald's app for collection or delivery. It is filed under Vegetarian. Availability is set per branch, so a smaller site may not carry it at all.
McDonald's Fries price in 2026
There is no verified McDonald's McDonald's Fries price for 2026. McDonald's prices per branch and publishes no national list for it, so the accurate figure is the one your own branch shows in 2026. Any site quoting a single exact national price for this item is guessing, and we would rather show the gap.
Allergens declared
McDonald's lists none of the 14 allergens UK law regulates as an ingredient of this item. 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.
What 337 kcal means here
337 kcal is well above the Vegetarian 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.
A lighter choice in the same section
Sugar Donut sits in the same part of the menu at 197 kcal, which is 140 fewer than this for £2.69. That swap is the single biggest change available inside this section, and it needs no substitution or special request at the counter.
Finding it near you
We list 119 McDonald's branches across 4 of the four UK nations, with the Leeds postcode area holding the most at 9. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The McDonald's app confirms it in seconds.
Pro Tips for Ordering McDonald's 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. McDonald's lists sides separately from meals for exactly this reason.
Diet marking
McDonald's marks this as vegan and vegetarian. That is the chain's own classification of the recipe rather than a statement about how it is cooked, and vegan marking in particular sits alongside shared equipment at most of these brands.
