Roasted Sweet Potato Cubes – The Perfect Side

Roasted sweet potato cubes are in the bowl on the table with a piquant pistachio dressing on the chopping board | Hurry The Food Up

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.

How to roast sweet potatoes cubes

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!

First up, follow this explanation of how to cube sweet potatoes.

Or for a more visual guide, watch this video below.

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.

4 different types of roasted sweet potatoes are ready on the parchment paper on the baking tray | Hurry The Food Up

Ranked in order of deliciousness:

  1. peel + oil/salt
  2. no peel + oil/salt
  3. no peel no oil/salt
  4. 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!)

    I love roasted butternut squash and the dressing makes this extra delicious. A super versatile recipe and makes a great snack or side. Yum!

    1. Thanks a lot Shelby! Very kind of you to say. Glad you enjoyed it!

  2. 5 stars
    Wow, I like your wonderful stuff and easy to make your recipe.

    1. Tasty yet easy recipes that’s exactly that what we’re working for!! Really a pleasure to hear that! Thank you!!

  3. I AM AN Indian and when I was a kid i used to eat sweat potato cubes and Banarasi Paan Every day. I mean these are two of my favourite street food out there. Your blog throw me out back to those golden days. Thanks a lot for this awesome content.

    1. Wow! Sounds like a nice combo! Thanks for sharing these memories! 🙂

  4. I have tried a few if your recipes and I’ve made the farmer’s breakfast about five times now but this pistachio number didn’t work for me. I was intrigued by the pistachios but it was weird overall. I don’t mean to be negative but I just didn’t enjoy it. Live and learn. Next!

    1. Hey Patricia, no hard feelings! I guess everything’s not for everyone. I love this one, but I still hate mushroom soup :D. You’ll have to try another recipe now just to balance things up 🙂

  5. Help! Am I reading something wrong? In your “Nutritional Information,” this says 1,971 calories and a boatload of fat in this recipe. What am I missing

    1. Hi Irene! Woow, that is definitely a mistake from our side. Thanks a ton for pointing this out. I updated the nutri info. One serving is about 750 kcal. Still quite calorie rich, but no wonder with ingredients like pistachios, sweet potato and olive oil. All good calories though! 🙂
