Crispy Parmesan Smashed Sweet Potatoes
These Crispy Parmesan Sweet Potatoes get smashed, brushed with garlicky butter, and roasted face-down in Parmesan until they form a crackly, golden cheese crust you’ll want to peel off and eat first.

You only need about 10 minutes of prep and a handful of pantry spices to make them. Smashing the halves gives you more surface area, which means more crispy edges in every bite. Serve them as a cozy fall side dish or set them out with the Sriracha mayo as a crowd-pleasing appetizer that disappears fast.
Helpful Tips
- Dry the potatoes well: After washing, pat the sweet potatoes completely dry with a kitchen towel. Any leftover moisture will create steam and keep the cheese from crisping.
- Smash gently: Let the halves cool for a few minutes after the first roast, then press down slowly with the bottom of a cup. A gentle, even press flattens them without breaking them apart.
- Press firmly into the cheese: When you dip the cut side into the Parmesan, give it a firm press so the cheese sticks in an even layer. Good contact with the pan is what creates that cohesive, golden crust.
