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!

baked Sweet Potato cubes Tips + Tricks

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

    I never liked sweet potatoes my whole life, any way they were fixed, including sweet potato pie. I made these for my boyfriend. I do not make what I won’t eat, but he is special so I made the Baked Parmesan Sweet Potatoes and I tried them and OMGosh, they are so goood I can’t wait to make more! They were gone fast and now I asked to please make more, and make extra. Yes make these you will be glad you did, Thank you for your recipe

  7. Would these be just just as good with regular potatoes? I wanted to make these for my boyfriend but he insists that he doesn’t like sweet potatoes (although I would love to try them).

    1. They are great with regular potatoes!! Try them with those first and then maybe you can convince him to try sweet potatoes. 😉

  8. These are delicious.I was looking for a recipe to make for my kids for lunch using sweet potatoes. Found this recipe, threw it together in about five minutes, and now my kids have been quiet for like TEN WHOLE MINUTES while eating these sweet potatoes. They love them. (And I can’t stop sneaking them off their plates.) Thanks!!!!!

    We love sweet potatoes and this has become our favorite way of making them. I also add chopped onion and use a LOT more garlic because we love garlic! I will also try this in the slow cooker for gatherings. Thank you for a new staple!

    Oh man, those photos are awesome. I’m actually making some in the microwave now (short on time) and plan to top with some garlic salt, parmesan cheese and italian seasoning. Thanks for the inspiration!

    This was delicious! Definitely saving this recipe. Thanks! Finally, a quick and delicious way to serve sweet potatoes!

  15. I too have just developed a taste for sweet potatoes as an adult. I made these the other night and thought they were amazing. Thanks!

    I have made this with butternut pumpkin (Im from West Australia we call them pumpkin not squash????) and they are perfect as well. But the sweet potatoe were not bad either…thanks

  17. 5 stars
    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.

  18. 5 stars
    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.

  19. 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. 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!

  20. Made these this morning before I went to work. Oh. My. Goodness! This will be added to my regular day. These are so good!! Thank you for the amazing recipe!!

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

    1. 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!

  22. 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. 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!

  23. Fantastic!!!
    I made 2 changes:
    Mixed in a bowl rather than a bag
    Used minced garlic and salt instead of garlic salt
    This is my new “go to” sweet potato recipe! Everyone loves it!

  24. I was wondering if you can peel and cube the Sweet potatos a day ahead of making. TRying To prep for thanksgiving.

  25. 5 stars
    This is my go to recipe! I did make a few changes….
    I prefer to put my dry ingredients and Olive oIl and melted butter a large boWl and toss. After everything is coated, i add the parm!! I find that it coats everything Evenly. Love this!!!

  26. 5 stars
    These were delicious!! We aren’t super huge sweet potato fans, but this will be a regular in our house. There weren’t any leftovers and even my 2 year old ate them! Yummy side dish for any MEAL!!

  27. These were a super big hit at my Christmas dinner, people that don’t even like sweet potatoes loved them! This is a keeper!!

  28. 5 stars
    This dish was a big hit at our Christmas gala. I’m making them again tonight just for the two of us. They smell so good!!

    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!!!

  31. 5 stars
    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.

    We have found one of our new favorite recipes!! Sweet potatoes with parmesan cheese & yummy!! This is a side dish we will use over & over!

    This is the first time that I have made Baked Parmesan Sweet Potatoes. Pretty sure this is the ONLY way I will be making them from now on! SO, SO GOOD!

  34. 5 stars
    Just the recipe i needed to dress up my sweet potato! so delicious, my bf who doesn’t even like sweet potatoes thought they were yummy. definitely will do this again

    1. I love that! For someone who doesn’t like them, to like it. Thank you for letting me know 🙂

  35. 5 stars
    These were a big hit and we will make them many more times! This recipe will go in our rotation of sweet potato side dishes for sure.

  36. Trying later too excited!! Can I prep the sweet potatoes in the coating and let marinate for a few hours before using?

    1. I personally haven’t, but I am sure that would still be ok 🙂 Wasn’t sure if it makes them get too soft.

    1. Yes, though I personally like them straight from the oven/fresh. This is my make ahead instructions…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.

  37. 5 stars
    These are my very favorite side! My entire family loves them, especially my 4 year old. They are so quick and easy, and taste amazing.

  38. 5 stars
    These sweet potatoes are our new favorite side dish. I never thought about adding parm to sweet potatoes, but these are so good!

  39. 5 stars
    Wow wow wow! I followed the recipe exactly, other than I had (and used) both yams AND sweet potatoes. They cooked at a similar rate and I liked the color differentiation of white and orange. This was just incredibly delicious. Pretty much the only way I’m going to be cooking these tubers from here on out. Why mess with perfect? My boyfriend just devoured most of them. A few things:

    1). You can chop up the potatoes or yams, mix up the Parmesan butter coating up to a day or two before the BIG DAY.

    2). It took about 10-15 minutes longer in my crowded oven for these to cook, so beware if you are making this as a side dish at thanksgiving.

    That being said, everyone voted for their favorite side, and this one was the clear winner!

  40. These look amazing and will be sure to try…thankyou! Wondering why the need to mix in a baggie though?, can do the same thing in a bowl and skip another plastic bag in the garbage…

  41. 4 stars
    Such an enormous amount of sodium in this recipe! There is enough sodium in the cheese itself so I couldn’t justify using garlic salt. Garlic powder is just fine. Otherwise, it’s a great recipe.

  42. 5 stars
    I made this last week and am making again today. The first time I did equal parts sweet potato and yams, just for color difference. My boyfriend RAVED about this recipe, and that’s saying something bc he really isn’t a yam or sweet potato fan. Good job you!

    Hey Kristyn, I was looking for an Italian “flavor” for sweet potatoes to go with a pork medallion & spinach recipe I was making. This was just the thing I was looking for! Thanks – It turned out great and complemented the protein exactly as I was hoping. Perfect! Just a thought for your readers though, the nutrition info that you have posted with the recipe is for the entire dish. It can put some of us who watch this type of info off from even trying the recipe. My count is somewhere about 115 cals for one serving…whew 🙂

    1. Thank you for your sweet words! And thank you for the note on the nutrition information. We’ll update that. Thanks!

    I soaked the unpeeled potatoes for 20 minutes in cool water (after cubing) and then pat dry/ allowed them to dry before coating. I also used cast iron pans instead of a foil lined baking sheet. I added a sprinkle of olive oil to the pans before adding the coated sweet potatoes. (That was probably excessive as the pans were overly oily after cooking.) The pan that in which I spaced the potatoes turned out crispy and delicious. The pan which I crowded was delicious, but did not have the crispy outer. I cannot wait to try these again!

    Thank you for your recipe!

    1. Thanks so much for sharing what you did. I’m so glad this recipe turned out tasty for you! I do love the crispy outer on the potatoes as well. 🙂

  45. 5 stars
    These came out so tender and delicious. Thank you for the recipe. I’ll be adding this to my cookbook for sure!!

    1. I’d say maybe around 10 minutes, give or take? I haven’t tried these in the air fryer yet, but that’d be a great cooking option!

  46. So I am going to make these for a work party tomorrow but am having trouble trying to figure out if I should just cook them fully and then reheat at work? Or my other option would be to cut the sweet potatoes prior, put them in water in the fridge and the quickly assemble and pop in the oven at work. What would you suggest?

    1. How fun! Either option would work honestly… I’d say it depends on how much time you have at work. You can 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. Or baking them fresh is always delicious if you have the space/time to at work. Hope the work party goes well!

    These potatoes even pleased my picky husband who doesn’t care for sweet potatoes. They were very flavorful and easy to prepare. I put mine in along with a chicken dish at 350 degrees for 40 minutes and they were perfect. ❤️

  48. 5 stars
    These were delicious…
    I only used 1 cup of flower, I also added some cumin, old bay seasoning, pepper, garlic powder, and I also minced up a bit of onion too add too them!
    I made a seeet and spicy aoli to go with it!
    Great recipe!

  49. Any chance I could use a bag of store bought frozen sweet potatoes? And if so, what adjustments would I need to make in the recipe? Thanks in advance for your help.
