These Savory Smashed Sweet Potatoes are so good! Notice how I said “smashed” and not “mashed.” These are not mashed sweet potatoes, although I do have recipes for traditional mashed potatoes. These are smashed potatoes – I roast sweet potatoes in the oven, smash them with a fork and sprinkle with parmesan, and then broil for a few minutes until the tops are nice and crisp. They’re a great alternative to a sweet potato fries or a baked sweet potato when you want to switch it up.

These smashed sweet potatoes would be a great side dish to serve during the holidays if you’re looking for something a little different. I used two different colored sweet potatoes because it was pretty, but it’s totally optional. I top mine with a dollop of Greek yogurt, but they’re equally tasty without it.

What is the difference between mashed potatoes and smashed potatoes?

Mashed potatoes combine boiled potatoes with usually butter and milk to make a very soft, creamy potato dish. Smashed potatoes are roasted potatoes that are lightly smashed with a fork. They are crispier and have more texture than mashed potatoes.

How to Make Smashed Potatoes

Cut the sweet potatoes into ¾-inch thick, round slices. Try to get the slices as uniform as possible so that they’ll cook in the same amount of time. Season melted butter with salt, pepper, onion and garlic powder, and thyme and pour over the potatoes.

Roast the potatoes for 25 minutes and then remove from the oven. Gently smash each potato with a fork, spray with olive oil, and sprinkle with Parmesan. Broil the potatoes for a few minutes until crispy and the cheese is melted.

Smashed Sweet Potato Variations

  • Sprinkle with mozzarella instead of Parmesan.
  • Swap the thyme for fresh rosemary.
  • Omit the Parmesan and swap butter with olive oil to keep them dairy-free.

  1. Delicious. I had an extra sweet potato leftover from my holiday cooking. I wanted to try something different so I used this recipe. Five stars. I will make it again. 

  2. soo good! i almost ate them all in one night! i was lazy and didn’t bother putting the butter and everything in a separate bowl first – instead i brushed each potato round with butter and then i just shook garlic powder and garlic salt on top (that was all I had). these turned out DELISH! I don’t think i even really needed the parmesan. Afterwards I added hot sauce and served them with some fresh guacamole. I’m adding this into regular rotation! thanks for the recipe! 🙂

  3. Absolutely delicious! Instead of tossing in a bowl, I put everything in a 1 gallon zip lock bag and gave it a thorough shake. This gave a much more uniform coating and took a fraction of the time. I WILL be making this simple and delicious recipe again!

  4. Fantastic!  Paired with your Air Fried Bacon Wrapped Pork Tenderloin this evening and it was a hit.  My husband was drooling 🤣. Cant wait to make for my 5 year old granddaughter, she will love them.

  5. Where did you find the purple sweet potato and does it taste the same as a regular sweet potato? I’m intrigued!!

  6. I LOVE these!!  I’m always looking for new ways to make sweet potatoes and these are fantastic!  Thank you for another great recipe!!

  7. These are sooooo good. I actually don’t even use the onion powder, just the garlic. It is in the menu list but not the instructions so I left it out by mistake, but I personally don’t think it’s needed. 
    I mostly make these with pork chops, but also discovered they are great for brunch with eggs over easy on top!

    I gotta say these were delicious. Made some for Thanksgiving and even the picky eater granddaughter wolfed them down.. Was hoping for some leftovers – but there were none!! Thanks for a great recipe..

    I’ve since done them in the air fryer & my NuWave oven and perfect each and every time..

  9. We made these with 1/2 t. sour cream and bacon bits on each one after baking and they were AMAZING! To eat them leftover I just put them under the broiler again (pre-sour cream and bacon). I have gotten so many great recipes from you! Thanks!

  10. These were delicious!! I used all purple sweet potatoes which I’ve never tried before and loved the flavor and texture. Reheated the leftovers in the air fryer and they were just as good. 

  11. These were sooo good.  I used sour cream instead of yogurt, and I’m not sure I’ll make sweet potatoes any different in the future they were so good.

    I guess I’m confused by the serving size. They are sliced into rounds but the serving is a half of a potato – so should I cut each potato in half before slicing and keep separate on the cookie sheet? Or should it say 1/2 cup??? Thanks!
