These Smashed Sweet Potatoes are one of those side dishes that somehow steal the spotlight from the main course every single time. Thick slices of sweet potato are roasted until buttery and tender, then smashed and broiled until the edges turn beautifully crispy and caramelized. Finished with fresh Parmesan, garlic, thyme, and just a tiny pinch of nutmeg, they’re cozy, savory, slightly sweet, and completely irresistible.
The first time I made these, I honestly intended them to be “just a side dish,” but my kids kept grabbing them straight off the baking sheet before dinner even started. The crispy edges paired with the soft centers make them impossible to resist, and the garlic butter aroma filling the kitchen is reason enough to make them again.
They’re easy enough for busy weeknights but pretty enough to serve during the holidays or at family gatherings. Whether you pair them with roasted chicken, steak, or simply snack on them straight from the pan, these sweet potato rounds are pure comfort food. Love this recipe?

Ingredients
2 large sweet potatoes or 3 medium sweet potatoes, sliced into 1-inch thick rounds
¼ cup butter, melted
3 garlic cloves, minced
1 tbsp fresh thyme leaves
1 tsp kosher salt, or to taste
½ tsp freshly ground black pepper
Small pinch ground nutmeg
½ cup freshly grated Parmesan cheese
Directions
- Preheat the oven to 220°C / 425°F. Line a large baking sheet with parchment paper or lightly grease it.
- Slice the sweet potatoes into thick 1-inch rounds and place them in a large mixing bowl.
- In a small bowl, whisk together the melted butter, garlic, thyme leaves, salt, black pepper, and nutmeg.
- Pour the butter mixture over the sweet potatoes and toss until evenly coated.
- Arrange the sweet potato rounds on the baking sheet in a single layer, leaving about 1 inch of space between each piece.
- Roast for 25 to 30 minutes, or until fork tender.
- Remove the baking sheet from the oven and switch the oven to medium broil.
- Using the bottom of a glass, a potato masher, or a fork, gently press down on each sweet potato round until slightly flattened.
- Return the potatoes to the oven and broil for 3 to 5 minutes, or until the edges become golden brown and crispy. Watch carefully to prevent burning.
- Remove from the oven and immediately sprinkle with freshly grated Parmesan cheese. Serve warm.
Cooking Notes
- Try to cut the sweet potatoes evenly so they cook at the same rate.
- Don’t smash the rounds too thin or they may fall apart during broiling.
- Freshly grated Parmesan melts and crisps better than pre-shredded cheese.
- For extra crispiness, broil an additional 1 to 2 minutes if needed.
- Add chopped parsley or a drizzle of hot honey for extra flavor.

Recipe Science
Smashed sweet potatoes combine two cooking techniques; roasting and broiling; to maximize both texture and flavor. Roasting first softens the sweet potato rounds by converting starches into sugars, which enhances their natural sweetness. Once tender, smashing increases surface area, allowing more contact with direct heat during broiling for crispier edges and better caramelization.
Butter helps conduct heat and promotes browning, while garlic and thyme infuse the potatoes with aromatic flavor during roasting. Parmesan cheese contributes saltiness and umami while also creating a lightly crisp finish as it warms on the hot potatoes. Nutmeg works especially well with sweet potatoes because its warm spice notes complement the vegetable’s natural sweetness without overpowering it.
These smashed sweet potatoes are highly versatile and pair well with roasted meats, holiday meals, or vegetarian mains. Leftovers can be reheated in an oven or air fryer to restore crispness. The recipe also adapts easily with spices like smoked paprika, rosemary, or chili flakes.
This dish contains moderate sodium from Parmesan and added salt. Lower-sodium cheese or reduced salt seasoning can help reduce sodium levels while maintaining flavor balance.

FAQ
- Can I make these ahead of time?: Yes. Roast the potatoes ahead, then smash and broil right before serving.
- Can I use regular potatoes instead?: Absolutely. Yukon Gold or red potatoes work especially well.
- Why aren’t my potatoes crispy?: They may be overcrowded on the baking sheet or not broiled long enough.
- Can I make these dairy-free?: Yes. Use olive oil instead of butter and skip the Parmesan or use a dairy-free alternative.
- Do I need to peel the sweet potatoes?: No. The skin helps hold the rounds together and crisps nicely in the oven.
