Sides are where a Burger King order quietly gets expensive. 10 items sit in this section, from £2.49, and adding two of them to a burger often costs more than the burger did.
Fries are the default at £2.49 at 275 kcal for a regular portion, with a large portion priced separately. Onion Rings sit alongside them at £2.79, and the loaded fries options run higher again on both price and calories.
Portion sizing is the thing to read here. Most sides come in two or three sizes at different prices, and the step up is rarely proportional, so the larger portion is usually better value per gram. Each item page lists every size with its own price and calorie count.
No items match those filters.
