5 Tips for Keeping Food Hot in a Cooler

Preheat the cooler first Fill it with boiling water for a few minutes, then dump it out. This warms the walls so they don’t steal heat from your food.

Pack food as tightly as possible Empty space lets heat escape. Fill gaps with towels or crumpled newspaper to keep everything snug.

Wrap each dish in foil and a towel This adds extra insulation around individual containers. Double-wrapping helps retain heat longer.

Add hot water bottles or heated bricks for longer events Wrap them in towels and place them among the food. They act as heat sinks that extend hot holding time.

Use a thick-walled cooler with a tight seal Rotomolded coolers work best. Avoid disposable or flimsy soft-sided coolers, as they lose heat too quickly.
