Sweet potatoes are rich in fibre, low in fat and high in vitamins A and E. They also have high magnesium levels, which is important for converting the food we eat into energy and the general well-being of our bodies.
You can buy sweet potatoes all year round but they are best in the UK from October to March. They are thought to have first been cultivated in Central and South America but are now a much-loved ingredient all around the world.
Sweet potatoes are a delicious alternative to regular potatoes and can be mashed, roasted or cooked as chips and crisps too.
Like potatoes, sweet potatoes do not count as one of your five a day, but they can contribute to a healthy, balanced meal.

Sweet potato recipes
Give the sweet potatoes a good scrub under cold water before cooking to remove any dirt, just as you would regular potatoes. You can trim any hard, woody roots at the end of the potato too.
You can peel the sweet potatoes but the skin contains lots of fiber and when seasoned, it tastes delicious too. How you wish to cook and serve the sweet potato will determine how you should cut it. Continue reading for our guidance and tips.
You can cook a sweet potato whole as you would a regular jacket potato. The flesh is a little sweeter but it goes just as soft and fluffy. It works with all the same jacket potato fillings you know and love including baked beans and cheese, smoked mackerel and Senior Food Writer Jessica Ransom’s favourite; tuna mayo with cheese.
To cook a whole sweet potato in the oven, follow the method in our how to cook a baked potato guide.
For a smooth mash, we recommend peeling your sweet potato before cutting it into uniform chunks. The skin is perfectly edible and if you want to up your fiber intake we recommend keeping the skin in for some added texture.
- Bring a large pot of water to the boil
- Season with salt
- Cook the sweet potato until soft and tender. Around 5-10mins.
When the sweet potato is cooked, drain and mash with butter and milk, or as your recipe states. Season and serve while hot.
Just like a regular potato, you can use the microwave to cook a whole sweet potato but you won’t get the delicious crispy skin. Some people like to cook their sweet potato for a few minutes in the microwave and finish it in the oven for around 30mins to crisp up.
A microwave is a good option for preparing sweet potato for mashing too:
- Peel and dice the sweet potato and put it in a large microwave-safe container.
- Add a couple of tablespoons of water then cover with clingfilm and pierce a few holes in.
- Cook on high in the microwave until soft for a few minutes. This is a good option if you have limited hob space but it’s not drastically quicker or easier.
If you fancy a new breakfast or you’re in need of some light lunch inspiration, sweet potato toast is an excellent choice.
- Wash the sweet potatoes then dry them and slice thinly lengthways.
- Use a mandolin for the best results.
- Pop in your toaster for a few minutes then top with sweet or savoury toppings as you would regular toast.
Experiment and use sweet potatoes in your favourite recipes that call for regular potatoes and you might find a new favourite combination.
Senior Food Writer Jessica Ransom loves a baked jacket potato as an alternative side to a steak or with barbecue beans and grilled chicken.
In America, a sweet potato dish topped with marshmallows is traditionally served at Thanksgiving. If that combination of sweet and savoury is a step too far for you, we recommend starting with a fluffy baked potato loaded with salted butter, crispy bacon, and a drizzle of maple syrup.
To freeze sweet potato it’s best to peel and dice it. Boil until just tender then allow to cool before dividing into portions for the freezer. This can then be boiled to defrost and turn into sweet potato mash.
You can also prepare and freeze sweet potato chips:
- Peel, slice, and blanch the sweet potatoes then allow to cool and freeze in portions.
- Cook from frozen in an oven preheated to 200C/Gas 4.
- Make sure the chips are in an even layer and don’t forget to season and drizzle with oil before placing in the hot oven for 35-45mins.
Sweet potato is also a delicious healthy snack for dogs so instead of throwing your offcuts away, let your pet have a good crunch.
Sweet potato mash can be stored in the fridge for a couple of days but it’s best not to keep it longer than this, especially if your recipe used butter and milk. To reheat the mash either warm it through on the hob with a little more butter or give it a quick blast in the microwave.
Roasted sweet potato can be eaten cold in salads and is delicious when mixed in with couscous too. You can reheat it in the microwave or in a low oven but it’s not likely to crisp back up.
