Why are my roasted potatoes not getting crispy?
The usual culprits are overcrowding, not enough oil, or an oven that is not actually hot yet. Give the potatoes space in a single layer, use enough oil to lightly coat, and make sure the oven is fully preheated. A hot sheet pan helps the bottoms start browning right away, but crispness still depends on space and heat.
Do I have to parboil first?
No, but parboiling is the shortcut to that crispy-fluffy combo. If you skip it, roast longer and cut the potatoes a bit smaller, but expect slightly less crunch.
What potatoes are best for roasting?
Yukon Golds are my favorite for a creamy center and great browning. Russets get extra crisp and fluffy but can be a little more fragile. Red potatoes hold their shape well and roast nicely, just slightly waxier inside.
Can I make these ahead?
Yes. Roast them fully, cool, and refrigerate. Re-crisp in a hot oven right before serving. If you want to prep earlier in the day, you can parboil, drain, rough up, and refrigerate the potatoes for a few hours, then roast when ready.
Should I use parchment paper or foil?
For maximum browning, go straight on the pan (no parchment). If you want easier cleanup, you can use parchment, but skip preheating the pan and add a few extra minutes to the roast time. If you do preheat the pan, use caution adding parchment to a hot pan and make sure it is fully covered by the potatoes so the edges do not scorch.
