Match the substitute to your goal: maximum browning (use a rack) or minimal cleanup (use foil/disposable).
Create drainage: if using a rack/grates, set them over a rimmed, foil-lined sheet to catch drips.
Preheat if your food needs fast browning: preheat the pan/skillet for 2–5 minutes (carefully) before broiling.
Broil with vigilance: start 1–2 minutes early, rotate halfway (or flip if needed), and stop once the surface is browned.
Control smoke: keep a foil barrier on the drip side, avoid pooling grease, and let the broil chamber cool before handling.
