Steam Cubed Sweet Potato In Microwave

Did you ever get obsessed with a food? One that you were never that bothered for, but fall in love with and then cook with all the time?

Well, that is me with cubed sweet potatoes.

I had rarely had a sweet potato, up until 2015 when I first discovered the paleo way of life.

On paleo white potatoes are swapped with sweet potatoes and all of a sudden I am cooking with sweet potatoes all the time and love how easy and fast they cook.

But my favourite method with sweet potatoes was always to peel them and cut the sweet potato into cubes and cook them in the air fryer.

They were so crispy like regular white potatoes, and you can load them into any of your favourite dishes. Though I always had them over soup as an alternative to croutons.

But I also wanted to see how the microwave compared and what steamed cube sweet potatoes would be like.

Can You Microwave Sweet Potato Cubes?

Yes, you can. Cooking sweet potato cubes in the microwave is very easy and you are using a steamer basket to perfectly cook them.

Sweet potato cubes in the microwave are done in a similar way to other steamed microwave veggies and are also a really quick way to cook your sweet potatoes.

Fastest Way To Cook Sweet Potatoes

If you are looking for the fastest way to cook sweet potatoes, then nothing beats microwave sweet potato cubes.

If you microwave a whole sweet potato, then you will be looking at between 7-10 minutes depending on your microwave wattage.

Or if you air fry sweet potato cubes you are looking at about 12-15 minutes.

But microwave sweet potato cubes are just cooked on 5 minutes and fork tender on 8 minutes.

Just think, perfectly cooked sweet potato cubes in 8 minutes!

Parboil Sweet Potatoes

Another option is to use the microwave to parboil sweet potatoes. Simply cook for 3 minutes instead of 8 minutes and then the sweet potatoes will be cooked for long enough for you to freeze them for later.

Soften Sweet Potatoes In Microwave

Or you might be using the sweet potatoes in another meal and want them soft enough that they don’t make your skillet dinner a really slow process.

If you want to soften sweet potatoes in the microwave I would recommend 5 minutes cook time.

Pre Cut Sweet Potatoes

Or the lazy option is to buy pre cut sweet potato cubes and then you don’t have any prep to worry about.

You could then skip a step in our microwave chopped sweet potato recipe and then load them straight into your steamer basket.

As well as this you could also use pre cut veggie bags such as the sweet potato and butternut squash cube mixes from Morrisons.
