I think sweet potatoes are finally getting the recognition they deserve, and if you try these roasted sweet potato cubes, I think you’ll agree with me.
They are so versatile, that they can be used happily in both sweet and savoury dishes, and it’s a toss up to decide which is better.
Of course, everyone knows and loves sweet potato fries but this time we’ve gone for Roasted Sweet Potato Cubes with a Piquant Pistachio Dressing. (You can also check out our recipes for baked sweet potatoes and sweet potato mash, if you’re so inclined)
This oven roasted sweet potato side dish was made for me by a good friend on my birthday one year, and was so popular I barely got a taste before they were all snaffled up.
A crispy sweet potato alone is insanely tasty, but the pistachio dressing is just something else.
Plus, this recipe is totally vegan AND sweet potatoes are packed with vitamins. This sweet potato side dish is really everything you could want in a recipe.
We’ve tweaked the original cubed sweet potato recipe to include some extra health benefits, and found the quickest and easiest way to get the potatoes chopped and cooked.

Look, we know that not everyone knows how to bake sweet potatoes off the top of their head, so we’ve got some good tips for you!

Make sure you have a big, sharp knife. Something like this German-bladed chef’s knife is immense, but of course you can make do with what you’ve got.
To peel or not to peel? That is the question.
And it’s a good question. Generally we follow the rule that if the skin looks nice and relatively unblemished, leave it as it is.
If it’s looking kind of gross, get rid of it! And always wash first 😉
Oil really helps for roasting, and salt adds a lot to the taste. The chunkier the salt, the better.
For your perusal, we lovingly made four different roasted sweet potato recipes. Here are the results of our kitchen experiments.
Ranked in order of deliciousness:
- peel + oil/salt
- no peel + oil/salt
- no peel no oil/salt
- peel, no oil/salt
Notes from the kitchen:
- “Oil+salt is awesome on baked potato cubes (true). I love it most when the peel is on because it gets slightly crunchy which makes it fun to eat.”
- “Funnily enough, on the other hand I think peel and no oil/salt is the worst. Just boring peel.”
- “Best way to make roasted sweet potato cubes: just add oil and salt. No need to get rid of the healthy peel.”
So there you go. Now you know everything you need to know to make perfectly roasted and seasoned sweet potatoes.
Hopefully, these dreamy little cubes will become your go-to sweet potato side dish or even a full meal (especially with that pistachio dressing!)
