What cooks found out
Read from 149 reviews across all 32 recipes. The counts are how many cooks report it — including where they disagree.
Managing surface starch - coating pieces in cornstarch or cornflour before roasting, or soaking raw-cut potatoes in water to leach out excess surface starch - is associated with notably higher exterior crispness, though at least one reviewer found the soak-and-dry approach alone didn't meaningfully improve crispness.
Overcrowding the pan (a single large low-rimmed roasting pan instead of two sheet pans) collapses exterior crispness, while spacing pieces out in a true single layer supports it.
Cooking far longer than directed (twice the stated time) or adding a liquid ingredient like bouillon to the mix collapses exterior crispness even when interior tenderness or flavor still turns out fine - crisping needs correct timing and dry heat, not just more time or added liquid.
Roasting directly on a bare or parchment-lined sheet pan, rather than lining it with foil, is associated with better exterior crispness - foil appears to trap steam that a bare or parchment surface lets escape.
Sprinkling parmesan (with or without breadcrumbs) on the vegetables near the end of roasting, or just before a final toast under the broiler, is associated with a noticeably crisper exterior.
