The Best Smashed Sweet Potatoes Recipe
I’m not sure if its just me, but there’s something undeniably irresistible and addictive about smashed potatoes. The moment I tried traditional smashed potatoes, my mind couldn’t help but wander to the idea of trying out a sweet potato twist. It’s essential to note that these aren’t “mashed” sweet potatoes; they’re “smashed” sweet potatoes. I take sweet potatoes, cut them into evenly sliced rounds, give them a gently boiling until tender and then flatten them into thin, disk-like shapes. To elevate their flavor, I brushed them with a garlicky herb butter mixture, add a sprinkle of parmesan cheese, and then let them crisp up in the oven. If that doesn’t make your mouth water, i’m not sure what will.

How to Make Smashed Sweet Potatoes
Peel the potatoes then cut them into evenly sized pieces. You can cut them into 1-inch disk-like shape but I prefer to cut them into smaller chunks to ensure that they are finger-food sized.


Boil the Sweet Potatoes
Place the sweet potato pieces in a large pot and cover them with water. Add a teaspoon of salt to the water. Bring the water to a boil for about 15 minutes until the sweet potatoes are knife tender (not fork tender). Make sure to not cook them too soft or that will affect the structure once mashed. Trust me, I tested this recipe three time!
Once the sweet potatoes are tender, drain them in a colander and let them sit for a minute to allow any excess moisture to evaporate.
Smash the Sweet Potatoes
Line a baking sheet with parchment paper (do not skip this), then place the cooked sweet potato chunks on the baking sheet. Space them out enough as they will spread after mashing. Its essential that the potatoes are not touching for optimal crispiness.
Use the bottom of a glass or bowl lined with parchment paper to gently smash each sweet potato piece. You want to flatten them to about 1/2 inch inch thick. Make sure to not over smash.



Season the Sweet Potatoes
Melt the butter in the microwave in a microwave safe bowl. Once the butter is melted, add the minced garlic, thyme, paprika, salt and pepper. Mix it well until combined. Brush the butter mixture evenly over the smashed sweet potatoes then generously sprinkle each piece with parmesan cheese.



Roast in the Oven
Roast the sweet potatoes for about 20-25 minutes or until the edges are crispy and golden. Keep an eye on them to avoid burning.
Remove the smashed potatoes from the oven, and garnish with fresh parsley. Serve with my homemade honey mustard sauce.

How to make the Easy Honey Mustard Sauce at Home:
In a small bowl, combine the regular mustard, dijon mustard, honey, mayonnaise, apple cider vinegar, salt and pepper. Whisk the mixture together until it’s smooth and well combined. Taste the sauce and adjust the seasonings if needed. Add more honey or mustard to reach desired balance of sweet and tangy.
If you have time, refrigerate the sauce for 30 minutes to allow the flavors to meld. This step is optional but can enhance the sauce’s overall taste.


What’s the Difference Between Smashed Potatoes and Mashed Potatoes
The main difference between smashed and mashed sweet potatoes lies in their texture and appearance. Smashed potatoes are crispy, with slightly crunchy outer edges potato rounds. Mashed sweet potatoes are smooth, fluffy and cream just like traditional mash potatoes. My mashed sweet potatoes recipe is infused with brown butter and sage while these smashed sweet potatoes is a different way to enjoy sweet potatoes with parmesan.
Tips For the Best Smashed Sweet Potatoes
After experimenting with this recipe on three times, I’ve gathered valuable insights. Be sure to pay close attention to these tips as they’ll make a significant difference in your smashed potatoes.
Cut the potatoes in small, Uniform pieces : As you mash the potatoes, they naturally spread into broader pieces. I found that overly large chunks may not be as visually appealing or suitable for finger-foods. Additionally, given the sweet potatoes’ soft interior, larger pieces tend to lose their shape. This also helps to ensure that all the pieces have a consistent texture and crispiness.
Use Parchment Paper: Make sure to line the baking sheet with parchment paper. The first two times I tried this recipe I did not use parchment paper and they burned really quickly even with adding grease to the pan.
Line the Cup with Parchment: Whatever object you choose to smash the potatoes with, make sure to line it with a piece of parchment paper. When I tried to mash the potatoes directly with a glass cup, they would stick to the cup and pretty much became mashed potatoes.
Gently Smash, Don’t Flatten Completely: When smashing the sweet potatoes, be gentle. The goal is to create an uneven surface with some thicker and thinner areas. Avoid completely flattening them, as this will maintain a pleasing texture contrast.
Keep an Eye on Them: Watch the sweet potatoes closely as they roast. When the edges turn golden and crispy, and the cheese is bubbling and browning, they’re ready.

Recipe Variations and Substitutes
- Healthy Fat Alternative: Instead of butter, try avocado oil or olive oil instead.
- Seasoning Variations: Try other herbs and spice combinations like rosemary and thyme, cumin and paprika, or sage and nutmeg.
