Crispy Parmesan Sweet Potatoes 🥔

I started making these as a side and now they get more attention than whatever main they are sitting next to. Each sweet potato half bakes cut-side down right on a bed of butter, parmesan, and garlic, so it builds a golden, cheesy crust you can actually hear when you bite in. Five ingredients, almost no effort. They go with everything from a Tuesday chicken to the holiday table, and they always get picked clean before anything else.

Tips for Making This Recipe

  • Build the crust right on the parchment: butter first, then parmesan, then garlic powder and pepper, and set each potato cut-side down on top.
  • Use parchment paper, not foil. It keeps the cheesy crust from sticking so it lifts off in one golden piece.
  • Cut the sweet potatoes into evenly sized halves so they roast at the same rate.
  • Let them rest for at least 10 minutes after baking. The crust firms up and releases cleanly from the parchment.
  • Freshly grated parmesan melts into the best crust, but the shaker kind works in a pinch.

Frequently Asked Questions

Can I make these with regular potatoes?
Yes. The same butter-and-parmesan method works beautifully on halved Yukon Golds or red potatoes. Just adjust the time to their size.
Why bake them cut-side down?
That direct contact with the butter and cheese is exactly what creates the signature crispy, golden parmesan crust.
Can I add other seasonings?
Absolutely. A little dried Italian herb blend, smoked paprika, or fresh rosemary are all delicious additions.
How do I reheat them?
Warm them in a hot oven or air fryer to bring the crust back to life. The microwave will soften it.
