How to roast sweet potato

If you’re looking for the best way to cook sweet potatoes, you might want to try roasting them in pieces. Roasting sweet potato is similar to baking, only you save time by cutting it into small bite-size pieces. 

  1. You’ll need 2 sweet potatoes (if you’re cooking for two people), olive oil and your choice of seasonings. 
  2. Preheat the oven to 220°C.
  3. Cut the sweet potatoes into rough cubes, then put them into a large mixing bowl, along with a drizzle of olive oil and your choice of seasonings. Feel free to use any seasonings, like garlic or chilli flakes, to add a spicy twist. 
  4. Mix the seasoning and sweet potatoes together well so that all of the pieces are evenly coated, then pour them out onto a lined baking tray. 
  5. Place the sweet potatoes in the oven and bake for approximately 30-35 minutes until they are tender and golden brown.
  6. Serve these flavourful sweet potatoes with your favourite meat, fish or vegetables. 

How to boil sweet potato

For a delicious sweet potato mash, start by boiling the sweet potatoes.

  1. You’ll need 1-2 sweet potatoes (or more, depending on how many people you’re cooking for), salt and water.
  2. Peel the sweet potatoes using a potato peeler. This step is crucial, as the skin of a sweet potato can be tough.
  3. Using a chopping board and a sharp knife, cut the peeled sweet potatoes into even-sized pieces.
  4. Bring a pan of water to a boil and add a pinch of salt, then carefully pour in the pieces of sweet potato.
  5. Reduce the heat slightly and boil for around 20-25 minutes or until the potatoes are tender.
  6. Remove from the heat and drain in a collider. If you wish to mash the sweet potatoes, return them to the pan and use a potato masher.

Sweet potato fries are a tasty alternative to regular fries, and they’re also really easy to make.

  1. You’ll need 2 sweet potatoes, olive oil and your choice of seasonings. 
  2. Preheat the oven to 200°C.
  3. Cut the sweet potatoes into fries, then put them in a large mixing bowl, along with 1 tablespoon of olive oil and your choice of seasonings. Mix them together until each piece is evenly coated.
  4. Bake them in the oven for 20 minutes or until they’ve reached your desired crispiness (top tip: if you have an air fryer, you can pop them in for 20 mins at 200°C and get the same effect).
  5. Serve with your choice of dipping sauce, such as ketchup, mayonnaise or sweet chilli sauce.
All cooking appliances vary. These are guidelines only. Ensure the food is piping hot before serving. Do not reheat.
