12 things you didn’t know you could do with leftover potatoes

Posted by Sainsbury's on 22 February 2017

With the equivalent of 5.8 million whole potatoes binned by UK households every day, potatoes are one of our most wasted foods, according to the Waste and Resources Action Programme (WRAP). 

And they could have been used to make one of these spud-tastic recipes...

Soup, obvs

And it’s not just classic leek and potato - chunks of leftover boiled potato or spoons of mash can be cooked into pretty much any soup to thicken it. Because, unless it’s a fancy consomme, no one wants a watery soup. A little mash works wonders in stews and gravy, too.

Crisps with real a-peel

Prepping some spuds for mash or roasties? Wash first and keep the peel. Sprinkle with salt, pepper, chilli flakes and little olive oil and roast until crisp. The perfect snack while the rest of your dinner is cooking. Watch our video here

Potato farls

This traditional Irish potato bread can be made with leftover mashed spuds. So versatile you can serve warm with butter and/or jam, or use to mop up curries and stews. Yum.

Mash ‘n’ freeze

If you buy a big bag of spuds, it’s easy to let a handful go to waste. Make extra mash with your bangers and freeze portions of the mash in sealable plastic bags. Thaw overnight in the fridge or heat gently in a saucepan, adding a little butter, milk or cream if they’re looking a little dry.

Make ‘pizza’

Well, kind of. Use up baking potatoes, or warm through any leftover baked spuds, and top with peppers, tom sauce and milky mozzarella.

Really make pizza

We mean it this time, honest! Mashed potato has long been used in pizza dough in southern Italy, while thinly sliced boiled spuds with cheese, herbs and olive oil is a classic topping. Did someone say double carbs?

Get in a bind

No breadcrumbs to bind your meatballs? Use leftover mash instead in recipes like this one for chilli cumin lamb meatballs. Same goes for beef and veggie burgers.

Blend into brownies

Yes, really. A little mashed spud bulks out cakes and brownies, so you need less sugar and fat. The potato also gives this recipe a lovely fudgy texture.
