How do you get the Parmesan crust crispy?
Bake the potatoes until tender first, then place them on shredded Parmesan and bake again at high heat until the cheese browns and crisps, roughly 10-15 minutes.
Can you make these ahead of time?
Yes, bake the potatoes fully in advance, refrigerate, then reheat and add the Parmesan crust just before serving for the crispiest result.
What type of potatoes work best?
Russet potatoes are ideal because they have a floury texture that becomes tender when baked and pairs well with a crispy cheese crust.
Can you use grated Parmesan instead of shredded?
Shredded Parmesan crisps better during baking, but pre-grated can work if it lacks anti-caking agents; shredded from a block yields superior results.
How long does the second bake take?
The second bake typically takes 10-15 minutes at the same temperature until the Parmesan is golden brown and crispy at the edges.
