Everything You Need to Know About Burger King Sharebox
How to order Sharebox at Burger King
Sharebox is available at the till, on the kiosk screens and through the Burger King app, for collection or for delivery. It is filed under Sides. Branch by branch availability varies, which the app reflects once you choose a location.
Burger King Sharebox price in 2026
There is no verified Burger King Sharebox price for 2026. Burger King 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
Burger King declares 6 of the 14 allergens UK law requires to be listed for this item: celery, cereals containing gluten, eggs, milk, mustard and soya. 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.
A lighter choice in the same section
Loaded King Fries with Bacon sits in the same part of the menu at 454 kcal, which is 437 fewer than this. That swap is the single biggest change available inside this section, and it needs no substitution or special request at the counter.
Saturated fat
11.65g of saturates is 58% of the 20g reference intake. That figure is the one worth watching over a week rather than a meal, and it is the number that separates two items with similar calorie counts.
Salt worth knowing about
At 3.8g of salt it accounts for 63% of the 6g daily maximum the NHS recommends for adults, most of a day in one item. Salt in restaurant food is fixed in the recipe, so the only control you have is what else goes alongside it.
Pro Tips for Ordering Sharebox
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. Burger King lists sides separately from meals for exactly this reason.
What 891 kcal means here
891 kcal is well above the Sides average. That is most of a day's energy for a smaller adult in one item, so treat the rest of the order accordingly. 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.
Protein for the calories
It gives 3.9g of protein per 100 kcal, against a menu average of 3.7g across everything we hold for Burger King. That is about average for this menu, which matters more than the raw protein figure when you are comparing two items of different sizes.
