The price is missing here for a reason. Harvester does not publish one we could check, and a guess dressed as a figure is worse than an honest gap.

Everything You Need to Know About Harvester Mighty One
How to order Mighty One at Harvester
You can order Mighty One at the counter, at a Harvester kiosk, or in the Harvester app for collection or delivery. It is filed under Burgers. Branch by branch availability varies, which the app reflects once you choose a location.
Harvester Mighty One price in 2026
There is no verified Harvester Mighty One price for 2026. Harvester 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.
A lighter choice in the same section
Bhaji Burger (V) sits in the same part of the menu at 1208 kcal, which is 118 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.
Finding it near you
We list 5 Harvester branches across 2 of the four UK nations, with the Birmingham postcode area holding the most at 1. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The Harvester app confirms it in seconds.
Salt worth knowing about
At 5.4g of salt it accounts for 90% 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.
What 1326 kcal means here
1326 kcal is well above the Burgers 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.
Pro Tips for Ordering Mighty One
Ordering it
The figure in the table is the standard build. Anything added at the counter sits on top of it, and anything left out comes off, which is a normal request at Harvester rather than an awkward one.
Allergens declared
Harvester declares 5 of the 14 allergens UK law requires to be listed for this item: 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.
Protein for the calories
It gives 3.1g of protein per 100 kcal, against a menu average of 4.4g across everything we hold for Harvester. That is a weak ratio for this menu, which matters more than the raw protein figure when you are comparing two items of different sizes. On raw protein it ranks 3rd of 14 in its section.
