Best tinned sweetcorn

How does supermarket sweetcorn compare with Green Giant? Our taste test results reveal the crunchiest, most colourful and tastiest sweetcorn you can buy - and the best cheap options

We tested supermarket tinned sweetcorn against the branded version to see who makes the tastiest tins and if you can make savings on your supermarket shop.

In June 2021, our consumer panel blind-tasted salt-free tinned sweetcorn in water from Green Giant, alongside nine rivals - including pricey Italian La Doria sweetcorn and cheaper own-label supermarket tins from Asda, Morrisons, Sainsbury’s, Tesco and Waitrose.

Our Best Buy won tasters over with its crisp texture and subtle sweetness, while the worst lost marks for its bland taste and pale, unappetising appearance.

Whether it's worth opting for branded or not depends on where you shop; some supermarket options outshone the branded versions, while others failed to impress.

How much sugar is in tinned sweetcorn?

Woman reading sweetcorn label

None of the samples we tested have added sugar or salt, but there is some naturally occurring sugar in sweetcorn. This can vary based on the variety of corn and ripeness at time of harvesting.

The brand with the least sugar was La Doria at 3.3g per 100g. Asda has the most at 8.4g per 100g. That might sound like a lot, but it's no more than many other fruits and vegetables - a serving of sweetcorn still contains less sugar than a medium apple, for instance.

How to cook sweetcorn

Sweetcorn in microwave

You don't need to cook tinned sweetcorn, as it's ready to eat.

If you want to heat it up, most brands recommend cooking tinned sweetcorn in the microwave or on the hob in the water it comes in the can with. 

Microwaving sweetcorn usually takes two to three minutes in a covered, non-metallic dish. This will depend on how powerful your microwave is. Take a quick pause to stir halfway through cooking.

Cooking on the hob takes slightly longer – usually around three to five minutes on a low heat. Avoid boiling the sweetcorn as this can impair the flavour. You can also just add it straight to stews, casseroles or other dishes such as pasta and warm through.

How we tested tinned sweetcorn

Our tinned sweetcorn line-up was blind-tasted by a panel of people who regularly buy and eat tinned sweetcorn. 

The make-up of the panel broadly represents the demographic profile of adults in the UK. Each brand was assessed by 72 people.

The panellists rated the taste, texture, aroma and appearance of each product, and told us what they liked and disliked about each one.

The taste test was blind, so the panellists didn’t know which brand they were trying. The order they sampled the sweetcorn in was fully rotated to avoid any bias.

Each panellist had a private booth so they couldn’t discuss what they were tasting or be influenced by others.

The overall score is based on: 

  • 50% flavour
  • 25% appearance
  • 15% aroma
  • 10% texture
