Burger King Fries: The Classic Side
The plain Burger King fries are the most-ordered side on the entire UK menu, priced at £2.99 for a regular portion. They’re cooked in a shared fryer alongside breaded chicken and cheese products, so while the fries themselves carry no declared allergens, cross-contact is possible — see our full Burger King Allergen Menu for the complete breakdown if that matters to your order. Our team’s pick for anyone ordering fries as part of a meal: ask for them freshly cooked at busy times, since fries sitting under a heat lamp lose their texture faster than any other side on the menu.
Loaded King Fries Range
The Loaded King Fries range takes the standard burger king fries base and adds toppings, and it’s grown into one of the most requested sides on the burger king sides menu:
- Loaded King Fries (£5.99) — cheese sauce and seasoning over a full portion of fries.
- Loaded King Fries with Bacon (£6.49) — the same base with bacon pieces added.
- Truffle Loaded King Fries (£6.49) — part of the Gourmet Kings range, with a premium truffle-style seasoning.
A peppercorn loaded king fries variant has appeared periodically as part of the Gourmet Kings rotation — if you’ve seen this on the app or in-store, treat it as a limited-time addition to the Loaded King Fries family rather than a separate permanent line, and check our Burger King News page for the latest on any rotating specials.
Chicken Fries, Onion Rings & Cheese Bites
Beyond the fries family, the burger king sides line-up includes:
Garlic & Jalapeno Chicken Fries (£5.99) — breaded chicken strips, not to be confused with potato fries.
Onion Rings (£4.49 for 6pc) — at 198 kcal, this is one of the lowest-calorie options on the whole sides menu.
Chilli Cheese Bites (£4.99) — a crispy, cheese-and-chilli-filled snack side.
Vegan & Veggie Sides
For anyone avoiding meat, Burger King UK’s sides menu still has genuine options worth knowing about. Both the standard Fries and the specifically labelled Fries (Vegan) option are confirmed vegan-friendly at £2.99, cooked from the same simple potato base with no animal-derived ingredients declared. Halloumi Fries (£5.49) offer a satisfying veggie option beyond the potato-based sides, part of the wider Veggie & More range, and make a popular pick for anyone wanting something more substantial than a plain side. For the full plant-based picture across burgers, sides and everything in between, see our Vegan & Vegetarian Menu.
