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!

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

    Go to sweet potato recipe. It’s sooo good and you can’t go wrong adding extra garlic and butter

    1. Kristyn Merkley says:

      Glad you like it! Thank you so much for trying it!

  2. Amanda says:

    Going to try these tomorrow for a family dinner. If using 6 potatoes, do you think I would have to bake longer? I’m terrible with cooking and have no idea!

    1. Kristyn Merkley says:

      You probably will or you can spread it out over a bigger sheet pan & it might be the same time. You may want to double up or even triple the ingredients, since you have more potatoes. Just keep checking on the potatoes & you’ll know when they are done. 🙂 Good luck!

  3. Kaniele says:

    Yum! Can’t have cheese but will definitely try this! Thank you for sharing!

    1. Kristyn Merkley says:

      You are so welcome!! Glad to share! Let me know what you think 🙂

  4. Christin says:

    How would you suggest I reheat these? I want to make them for Thanksgiving but they will need to be reheated before eating.

    1. Kristyn Merkley says:

      I’m not sure how you’d want to reheat these. I usually bake them when I know we’ll be eating them. You could keep them in the oven on a low temp. That would be my only suggestion. I don’t think the microwave would work. They might just get soggy. Good luck!

  5. Carol says:

  8. Alisha says:

    I made these and they were delicious! However, they took way longer than 22 minutes. I was disappointed because they weren’t ready when the rest of my dinner was.

    1. Lil' Luna says:

      I am sorry they took longer, but I’m glad you liked them. I know all ovens are different & cooking times may be different. Mine is super hot, so I know things don’t cook as long as recipes suggest. Thank you for trying them!

    These are amazing. I made this and baked sweet potatoes and Brussel sprouts together.. yum. I also gave the sweet potatoe peelings to my dog and he loved them. Usually I don’t peel sweet potatoes as I eat the skin too, but for this recipie I peeled and doggie was happy.

    1. Lil' Luna says:

      Haha..glad he liked them! Thank you for stopping by and for sharing!

    These sweet potatoes have become a family favorite. I’ve also taken it to several potlucks and it’s always a winner. I live in the south so most people around here think sweet potatoes can only be baked or candied. Thanks for expanding my horizons.

    1. Lil' Luna says: are so welcome!! Thank you for giving them a try!! So glad they are a favorite!
