Oven Roasted Sweet Potato cubes

Have you ever roasted sweet potatoes? If you haven’t, we are hoping we can convince you to because they make the greatest side dish to any meal!

Roasting sweet potatoes is easier than you think. We will show you how easy it is to do with today’s recipe for Baked Sweet Potato Cubes. It was inspired by our recipe for Baked Parmesan Potatoes that we’ve made for years.

We tried the recipe using sweet potatoes and fell in love with the combo of sweet and savory the potatoes and seasonings provide. The best part about these oven roasted sweet potatoes is that it’s super simple. It took just about 5 minutes to throw together and then we had to bake them for about 20 minutes.

They were so good and were literally gone in minutes!

How to roast sweet potato cubes

To make these roasted sweet potato cubes, you’ll begin by preheating your oven to 400 degrees.

CUBE + SEASON. From there, peel and cube the sweet potatoes into 1-inch cubes. Set these aside and combine the garlic, oil, butter, salt, Parmesan cheese and Italian seasoning in a Ziploc bag and mix well.

TOSS. Toss the potatoes in the bag until they are well coated. Place on a foil-lined cookie sheet that has been greased.

BAKE. Spread the sweet potatoes on the cookie sheet and bake for about 20 minutes. Sprinkle with dried parsley, if desired. Easy and delicious!

We love serving these cubes as is, but for even added flavor like to add:

  • chopped parsley
  • Shaved Parmesan
  • chives/green onions

How to make crispy sweet potato cubes? These cubes end up soft and a tid crispy but to make them even more crispy, be sure to flip half way through and broil for the last minute or two.

Can you reheat sweet potato cubes? Just store in an air-tight container in the fridge for 2-3 days and reheat in the microwave or back in the oven for 10 minutes to get them crispy again.

These Parmesan sweet potatoes are great for the holidays. Since the recipe only calls for 2 potatoes, take note of that when doubling, tripling or even quadrupling. Here is a guide to help with that knowing that 2 potatoes serves 2-3 people

  • 2 people – 2 potatoes
  • 5 people – 3-4 potatoes
  • 10 people – 8 potatoes
  • 15 people – 10-11 potatoes
  • 20 people – 15-16 potatoes

    Honestly looks really delicious! I used to make something super similar to this with my husband. The two best ways both me and him lost weight were from this blog’s recipes and following a proven plan. We actually lost a lot of weight following this program we found. Not sure if I am allowed to post links on here but was the program we used. Hope it helps someone as well.

    I think the butter was a bit unnecessary & unhealthy, but everything else made for a delicious combo. next time i’ll add a little more olive oil and skip the butter. I added fresh parsley after pulling the potatoes out of the oven. loved it!!!
