If you’re ordering fries at Burger King UK, you’ve actually got more choice than the counter menu suggests. This guide covers exactly what’s on the burger king fries menu, what each option costs, and which one is worth ordering, based on the current UK menu and pricing.
None of this requires guesswork once you know what to check — most of the fries range sits alongside the rest of the Sides section, and a few of the loaded options are easy to miss if you’re only looking at the burgers.
What’s Actually on the Burger King Fries Menu Right Now
Burger King UK’s burger king fries lineup breaks into two groups: the standard side, and the loaded range that adds sauces, cheese or toppings on top of the same base fries.
Standard Fries — the classic salted fries, served as a side or as part of a meal.
Loaded King Fries — fries drenched in cheese sauce.
Truffle Loaded King Fries — fries smothered in truffle sauce with crispy onions.
Gourmet Loaded King Fries — fries drizzled with toasted onion and cheese sauces, topped with pink pickled onions and bacon pieces.
Bacon Caesar Loaded King Fries and Peppercorn Loaded King Fries also appear on the current UK menu, though availability can vary by branch — check the BK app before you order if you’re set on one of these two specifically.
Garlic & Jalapeno Chicken Fries — a different item entirely: chicken fries (not potato fries) with a garlic and jalapeno coating.
For the full picture, the full Sides Menu covers onion rings, chicken nuggets and the other non-burger options if fries aren’t quite what you’re after.
Burger King Fries Prices in the UK (2026)
Burger King UK doesn’t publish separate small/medium/large till prices for standalone burger king fries the way some rivals do — the £2.99 listing above is for the standard portion. A larger size is sometimes available as a meal upgrade or through a Royal Perks app upsize offer, but the exact upsize price isn’t consistently published, so it’s worth checking the app on the day rather than assuming a fixed cost. Prices can also vary slightly by location — motorway services and airport branches tend to run a little higher than high street restaurants.
For a full breakdown of everything else on the menu, current menu prices are worth a look before you place a bigger order.
Loaded Fries: Every Flavour on the Menu
Loaded King Fries
The standard option: fries drenched in cheese sauce. Straightforward, no other toppings involved, and the cheapest way into the loaded range at £5.99.
Truffle Loaded King Fries
A step up in flavour — the same fries base smothered in truffle sauce and finished with crispy onions. This one leans richer and more savoury than the cheese-only version, and it’s the closest thing on the fries menu to a premium side.
Gourmet & Bacon Caesar Loaded King Fries
The Gourmet version adds toasted onion and cheese sauces plus pink pickled onions and bacon pieces — more going on than the standard Loaded King Fries, and closer to a meal in itself if you’re sharing. Bacon Caesar Loaded King Fries also appear on the current menu, though descriptions and availability can differ by branch, so it’s worth checking in-app or in-store what’s actually on offer that day.
Garlic & Jalapeno Chicken Fries
Worth calling out separately because it isn’t potato fries at all — this is chicken, cut into fry-shaped strips and coated in a garlic and jalapeno seasoning. If you came here looking for a spicier burger king fries option, this is the one, not a spice added to the potato range.
Are Burger King Fries Vegan?
Yes — the standard Fries at Burger King UK are suitable for vegans. That’s specifically the plain, standard fries; once you move into the loaded range, cheese sauce, bacon pieces and other toppings take most of those options out of vegan territory. If you’re ordering plant-based and want fries alongside, standard Fries is the safe choice, though as with any fast food kitchen, cross-contact with non-vegan items during frying is possible — check the allergen information in-app if that matters to you.
Burger King Fries vs McDonald’s Fries
Taste Compared
Burger King’s fries are cut thicker than McDonald’s classic fries and have a firmer bite, with a more noticeably salted finish. McDonald’s fries are thinner and tend to be crispier on the outside. Which is better comes down to preference — thick-cut fans usually favour burger king fries, thin-and-crispy fans usually favour McDonald’s.
Price Compared
At £2.99, Burger King’s standard Fries sit close to McDonald’s regular fries pricing, with both chains generally in the same ballpark for a standard portion. Loaded and specialty fries options push the price up at both chains, and exact comparisons shift often enough that it’s worth checking current pricing at both apps rather than relying on a fixed figure.

FAQs About Burger King Fries
Are Burger King fries vegan?
The standard Fries are suitable for vegans. Loaded fries options generally aren’t, due to cheese sauce, bacon or other non-vegan toppings.
What’s the largest fries size?
Burger King UK doesn’t list a separate large-size till price for standard Fries — a larger portion is sometimes available as a meal upgrade or an app-based upsize rather than a fixed standalone size. Check the BK app for what’s currently on offer.
Do fries prices vary by branch?
Yes, slightly. Motorway service stations and airport locations tend to charge a little more than standard high street branches.
If you’re watching the overall bill rather than just the fries, more ways to save at Burger King covers app deals and upsize offers that can bring the cost of a fries-heavy order down.
Final Thoughts
None of these burger king fries options are complicated to choose between once you know what’s actually on the menu — they’re mostly small differences in toppings rather than anything you need to plan around in advance. If you’d rather make something similar at home, you can also try making Onion Rings at home as a different side to pair with your burger.
