Slow cookers prepare food over a longer period at lower temperatures. The New GreenPan Slow Cooker is perfect for busy weekdays and family dinners of stews, casseroles, soups and curries.

You don’t need to add oil to a GreenPan Slow Cooker, the ingredients won’t stick thanks to the healthy, PFAS-free, Thermolon™ ceramic non-stick coating specially designed for the higher heat requirements of electrical appliances.

So, the Slow Cooker is clearly incredibly convenient, but is it cheaper to run than an oven?

The Verdict is in …

The costs can vary depending on the size of the slow cooker, which can range from a compact 1.5 litres suitable for two people up to 7 litres for big families and batch cooking. The average energy cost of a slow cooker annually is £59, compared to £316 for a conventional oven, according to household energy specialist Utilita.

And, according to Direct Energy, a typical electric oven uses between 2,000 to 5,000 watts of energy, which is over 100 times higher than the energy consumption of a slow cooker.

Of course, don’t forget to take into account the time it takes to pre-heat the oven too and the heat lost every time you open the oven door when switched on.

The NEW PFAS-free GreenPan Slow Cooker, RRP £199, is available in Stainless Steel, Glossy Black, Blue Haze and Cloud Cream from John Lewis, Lakeland, www.greenpan.co.uk and selected retailers nationwide.
