Today’s Roasted Sweet Potato Cubes is one we love so much we make them almost weekly!! They’re one of our favorite side dishes and are also great in salads, burger bowls and more.
We first tried these roasted sweet potato cubes over a decade ago, inspired by our recipe for Parmesan Potatoes that we’ve always made. Since then, the entire family has fallen in love and asked that we make them regularly.
We love that they take about 5 minutes to prep and 20 minutes to bake. They are so simple and so delicious, and our go-to side along with our Roasted Brussel Sprouts and Oven Roasted Vegetables.
Why You’ll Love Them + Why They Work:
- Simple. This easy side dish takes just about 5 minutes to throw together and 20 minutes to bake.
- Flavor. The combo of sweet and savory potatoes, plus the cheese and seasonings, is incredible.
- The bag makes coating easy. Shaking the sweet potatoes with butter, oil, Parmesan, garlic, and seasonings helps every cube get covered.
- Cutting even cubes helps roasting. 1-inch pieces cook evenly and become soft and tender while baking.
Roasted Sweet Potato Ingredients
- Unsalted butter, melted (2 tablespoons): Adds flavor and helps the coating cling to the sweet potatoes.
- Olive oil (1 tablespoon): Helps the sweet potato cubes roast and prevents them from drying out.
- Grated Parmesan cheese (¼ cup): Adds salty, cheesy flavor to the coating and a crisp once it’s cooked.
- Minced garlic (2 teaspoons): Adds savory garlic flavor.
- Garlic salt (½ teaspoon): Seasons the sweet potatoes and adds extra garlic flavor.
- Italian seasoning (½ teaspoon): Adds flavor that pairs well with the Parmesan and garlic. Basil seasoning also works. To change the flavors, try a combination of cumin, garlic powder, chili powder, black pepper, and paprika.
- Sweet potatoes, peeled and cut into 1-inch cubes (2): Creates the sweet, tender base of the side dish.
- Dried parsley, optional: Adds color and a simple finished look before serving. We usually use chopped curly parsley for this.
How to Make Roasted Sweet Potato
PREP. Preheat the oven to 400°F. Line a baking sheet with foil and spray with nonstick cooking spray. Set aside.
SEASON. Place butter, olive oil, Parmesan, minced garlic, garlic salt, and Italian seasoning in a large resealable plastic bag and mix well. Peel and cut sweet potatoes into 1-inch cubes. Add to the bag and shake until well coated.
BAKE. Place coated sweet potatoes on the prepared baking sheet and spread out evenly. Bake for 18–22 minutes until fork tender.
To make them even more crispy, flip halfway through and broil for the last minute or two.
Serve warm, sprinkled with dried parsley, if desired. Serve these flavorful potatoes on salads, in burritos with black beans, or grain bowls with rice, quinoa, or farro.
Air Fryer Directions
- Preheat the air fryer to 400°F.
- Working in batches, air fry for 6-8 minutes, flip, and fry for another 6-8 minutes.
- Do not over-crowd the air fryer basket, or the potatoes will steam instead of roast.
Kristyn’s Recipe Tips
- Cut the sweet potatoes into even 1-inch cubes so they roast at the same rate.
- Use a large resealable bag so the coating has plenty of room to cover every piece.
- Spread the cubes in an even layer on the baking sheet so they roast instead of steam.
- Check for tenderness with a fork before removing them from the oven.
- To make them extra crispy, flip the cubes halfway through and broil for the last minute or two of cooking time.
- Make-ahead tip: peel and cube the sweet potatoes earlier in the day, then coat and roast them right before serving for the best texture.

This recipe was originally published October 2015.
I am confused about the amount of potatoes to use. The recipe says serves 6, and to use 2 potatoes, but in another area it says this:
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
When I go to the print version for 12 servings, it says to use 4 potatoes.
I am cooking for 8 people, and thought I’d use 12 serving measurements from the “print” version
Are the measurments accurate? It doesn’t seem to be as far as amount of potatoes
Delicious delicious no left overs you saved me for tonight’s dinner side dish thank you
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.
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!
I see the comment about reheating for 10 minutes. Is that at 400° also? Thanks!
Yes! You can reheat at 400.
Favorite sweet potato recipe. Make them every year for Thanksgiving!
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. ❤️
Oh I’m so glad!! Sounds like a perfect compliment to the chicken dish too. Thanks for sharing!
Best recipe I’ve found w/sweet potatoes. The entire family loved it! Thank you
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?
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!
Any idea how long in an air fryer for 1-2 potatoes?
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!
On the nutrition value what serving size is that based from?
I’d say about 1 cup, give or take.
These came out so tender and delicious. Thank you for the recipe. I’ll be adding this to my cookbook for sure!!
You’re welcome! So glad you enjoyed the recipe!
Delicious!!
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!
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. 🙂
So delicious!!!
Thank 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 🙂
Thank you for your sweet words! And thank you for the note on the nutrition information. We’ll update that. Thanks!
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!
Awe, thank you so much for sharing that!! Tell him, thank you!
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.
Thank you for trying it!
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…
Yes, you can totally mix in a bowl 🙂 Enjoy!!
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!
Woohoo!! Glad it was the winner! Thank you!
I would share a picture, but the disappeared SO fast!! Excellent!!!!
That’s what I love to hear! Thank you so much!
These sweet potatoes are our new favorite side dish. I never thought about adding parm to sweet potatoes, but these are so good!
Just made these again last night and they are always a huge hit with my family!
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.
These were a huge hit at Thanksgiving! So easy and everyone loved them
I am glad you had them at Thanksgiving! Thank you!
Can I make these a day ahead
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.
Trying later too excited!! Can I prep the sweet potatoes in the coating and let marinate for a few hours before using?
I personally haven’t, but I am sure that would still be ok 🙂 Wasn’t sure if it makes them get too soft.
Delicious!! the husband and I both agree to add this to our recipe book! thank you!
Glad to hear that! Thank you so much 🙂
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.
Yay!! So happy you liked them! Glad to hear they make the rotation! Thank you!!
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
I love that! For someone who doesn’t like them, to like it. Thank you for letting me know 🙂
broiling them at the end really did FINISH them off perfectly. Thanks!
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!
Just made these again last night, and they are so good! A huge hit with my family!
We have found one of our new favorite recipes!! Sweet potatoes with parmesan cheese & baked..so yummy!! This is a side dish we will use over & over!
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 https://bit.ly/2JR1wT5 was the program we used. Hope it helps someone as well.
Thanks for sharing!
These are amazing! Thank your so much to share your recipe, i love parmesan sweet potatoes.
You are so welcome!! I am glad to share 🙂 Hope you like these!
Going to make these when my sister comes to visit in October. Thanks for the idea.
You are so welcome!! Hope she likes them!! Thank you!
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!!!
Thank you so much for trying them 🙂
lOVE THIS IDEA! aLL WINTER i’VE BEEN MAKING MINE WITH SALT, PEPPER, CHOPPED GARLIC, AND SLICED ONIONS ADDED TO THE SWEET POTATOES. tHEN I PUT THEM INTO A PREHEATED 450 DEGREES OVEN AND THEY ROAST UP SO WONDERFULLY, CARMELIZING THE ONIONS, GARLIC AND POTATOES! THEY ARE SO DELICIOUS I EVEN FIND MYSELF MAKING THEM FOR MY BREAKFAST MANY TIMES!
Sounds yum! Nothing wrong with having them for breakfast! 🙂
This rec was great.
Thank you so much!
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 am glad it was a hit!! We love them at our house, too! Thank you so much!
These were a super big hit at my Christmas dinner, people that don’t even like sweet potatoes loved them! This is a keeper!!
That’s what I love to hear!! Thank you so much for letting me know!
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!!
I wasn’t either, but now I love them! Glad you liked these! Thank you!
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!!!
Sounds great!! Thank you for sharing that!
It took a lot longer to roast. Just ok tasting.
Thank you for trying them 🙂
no joke these little babies were of the showstoppers at tonight’s Thanksgiving dinner!
Woohoo!! That makes me so happy! Thank you so much for sharing that!
I was wondering if you can peel and cube the Sweet potatos a day ahead of making. TRying To prep for thanksgiving.
You sure could!! I totally know what you mean! Enjoy!
Do you know what the serVing size is for your calories listed aBove?
Wow! Those are the best sweet potAtoes ever!
I agree!! 🙂 I am glad you think so! Thank you for trying them!
These potatoes are fricken delicious. My 2 year old DEVOUREd them. Very toddler friendly…
LOL!! That makes me happy to hear!! Thanks so much for letting me know!
Can’t wait to try the sweet potato recipe. Thanks for sharing.
You are so welcome!! I am glad to share. Thank you!
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!
Yay!! I am so glad you like it! Your changes sound great, thank you for sharing!
These are really good! I will make them again.
Woohoo!! Love to hear that! Thanks for letting me know!
Go to sweet potato recipe. It’s sooo good and you can’t go wrong adding extra garlic and butter
Glad you like it! Thank you so much for trying it!
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!
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!
Yum! Can’t have cheese but will definitely try this! Thank you for sharing!
You are so welcome!! Glad to share! Let me know what you think 🙂
How would you suggest I reheat these? I want to make them for Thanksgiving but they will need to be reheated before eating.
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!
Hi Kristyn,
I just made the sweet potato recipe. It was absolutely delicious, thanks for sharing.
Oh, I am so glad you liked them! Thank you so much for letting me know!
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!!
You are so welcome!! Thank you so much!! I am so glad you liked them!
I found this recipe and now I can’t stop making it! There are delicious!
LOL!! I’m glad 🙂 Thanks so much!
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.
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.
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.
LOL..you are so welcome!! Thank you for giving them a try!! So glad they are a favorite!
Will be making these tonight!! These look fantastic!!
A nice change from the tradiTional veggie. A very tasty dish.
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
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!
Thank you for trying them! Glad, I’m not the only one!
These are DELISH! And so easy. Do you have the nutritional information?
Thank you so much for sharing????
I don’t, I’m sorry! But, they are delish!! Thank you!
Do you know the nutrition info for these? ????
Wondering the same thing ????
I was wondering the same thing.
These are amazing!
Thanks so much!!! They are 🙂

I made this last night! Delicious! Would you mind if I used your post and pictures on my blog?
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!
Thanks so much for stopping by and trying these! I hope you liked them and yours sound delish!
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!
Great ideas!! They have become a favorite in our home, too! Thanks for letting me know!
wow looks so delicious. Amazing pictures too. I love sweet potato, thanks for sharing the recipe.
Thank you Amallia! We sure love this recipe..hope you do too!
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!!!!!
YAY – I’m so glad to hear that!! They are definitely a favorite at our house too. 😉
Made this as a side for dinner tonight, so tasty!!!
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).
They are great with regular potatoes!! Try them with those first and then maybe you can convince him to try sweet potatoes. 😉
thank you so much for sharing this. I made them last night and they were DELICIOUS!!!
Just made this tonight (halved the recipe for one sweet potato). It was delicious! Thank you!
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!
