Labour drain
Peeling, chopping and slicing consume hours of paid kitchen time every week. Those are the most expensive hours a site has.
Ready-to-use onion · UK & Ireland
Cooked Onions supplies ready-to-use Spanish onion, steam-cooked in a shelf-stable pouch, to hotels, cafés, restaurants and manufacturers across the UK & Ireland. 100% yield, 18+ months ambient, allergen-free. The prep’s already done.
Peeling, chopping and slow-cooking drain the most expensive hours a kitchen has, and raw onion loses up to half its weight before it earns a penny.
Sealed raw, cooked at 121 °C, flash-chilled. The core lines carry one ingredient, nothing added, and every drop of flavour kept.
Slow-cooked, not dehydrated. Open the bag, pour, and the dish tastes like an hour you never spent.
The problem
01
Peeling, chopping and slicing consume hours of paid kitchen time every week. Those are the most expensive hours a site has.
02
Cold chain logistics, perishability and food waste erode margin quietly, and never appear as a line on the invoice.
03
Seasonal variation in pungency and freshness makes the same dish taste different in March and in August.
04
Refrigeration, storage space and gas for raw inventory add up fast, and all of it is spent before service starts.

Cost your onion
Roughly how much raw onion does your kitchen or line buy a week? The ranges below use the same evidenced figures as the numbers above, nothing invented.
Cooked at 121 °C
Nothing added. Nothing lost.
The core lines carry one ingredient on the label: Spanish onion, steam-cooked in its own juices inside the sealed bag. See how it’s cooked
The range
The whole method
Cut the corner of the bag. That's the knife work done for the week.
Onion and its own cooking juices go straight into the pan. The flavour base pours out with it.
Same colour, same sweetness, every site, every service. No trim bin.
Where it goes: toppings, sandwiches, burgers, pizzas, pastries, cheeses, pastas, dairy, jams, desserts, croquettes, pies, sauces.
The honest comparison
| Cooked Onions | Raw onion / IQF | |
|---|---|---|
| Yield | 100% | Loses 20–50% to peel, trim and cooking |
| Pricing | Stable year-round | Exposed to seasonal swings |
| Food safety | Commercially sterile: cooked at 121 °C in the sealed pouch | Contamination potential |
| Infrastructure | None needed | Processing investment required |
| Customisation | Recipes with added ingredients | Onion only |
| Storage | Room temperature | Cold storage, −18°C to fridge |
| Energy cost | None | Ongoing refrigeration and gas |
| Shelf life | Over 18 months | Short or frozen-dependent |
A fixed specification and a steady supply mean pricing insulated from seasonal spikes, so procurement budgets hold and margins stop leaking through cold-chain bills, trim bins and thaw purge.
