Best roast potatoes

Choosing frozen roast potatoes is an easy way to save time and effort on Sunday lunch preparations. But are Aunt Bessie’s the tastiest, or are you better off going for a pack of own label roasties?

A piping hot pile of golden roast potatoes is a glorious thing, but there’s no need to spend hours in the kitchen preparing them. Our taste test has uncovered some delicious, easy to cook frozen roast potatoes that can be on your plate in a matter of minutes. 

In September 2020, we tested Aunt Bessie’s and Bannisters roasted potatoes alongside eight cheaper supermarket own label options from the likes of Tesco, Aldi and Asda.

We uncovered some standout spuds that make an ideal accompaniment to any roast dinner. But there was also disappointment to be had, with lower scorers lacking in both flavour and crispiness.

How we tested

The products were assessed by a large panel of consumers who regularly consume roast potatoes.

The make-up of the panel broadly represents the demographic profile of adults in the UK.

Each roast potato was assessed by 68 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 roast potatoes 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
  • 20% texture
  • 5% aroma
