Why this matters
Plant foods do not all soften at the same speed. Dense cell structure, surface moisture, starch, and piece size affect how quickly heat reaches the center and whether the outside browns. The goal is not always maximum heat: beans prefer a gentler simmer, mushrooms need room for water to escape, and tender greens often need only residual heat.
How to do it
After washing, spin leafy vegetables or spread cut vegetables on clean towels and pat thoroughly dry. Toss with oil only after surface water is gone.
What to look, hear, or feel for
Oil coats instead of beading off, and the oven produces browned edges rather than a tray of steam. Pieces should sit in one layer.
When something goes wrong
If the tray is watery, move half the vegetables to another hot tray and continue roasting. Salt very watery vegetables at the time the recipe recommends.
Try it in a real meal
Apply the lesson to sheet-pan vegetables, soups, salads, beans, and quick skillet sides.
