Quick answer: Choose a food warming mat if you want to keep several of your own serving dishes warm on a dinner table and store it flat. Choose a warming tray for a smaller, rigid warming surface on a buffet counter. Choose chafing dishes for large buffet lines, catered events or anywhere without an outlet.

When a food warming mat is the right pick
A food warming mat is a flexible heating surface you lay on the table and set your serving dishes on. It's the easiest option for Thanksgiving or Christmas dinner, where you want the turkey, sides and gravy to stay warm through seconds without moving anything into chafers. Look for adjustable heat, a timer, a child lock and automatic shut-off. Our WarmRoll mat has all four, and the rollable touch-control mat is another option.
When a warming tray is the right pick
A warming tray is a rigid heated plate, usually with a glass or stainless top. It's a good fit for a buffet counter or sideboard where you want a defined "hot zone." See the 22-inch glass-top tray or the more compact stainless warming tray.
When chafing dishes are the right pick
Chafing dishes hold food in a pan above a water bath heated by fuel cans. They're the standard for catered buffets because each one holds a full pan, they look professional, and they don't need an outlet. Pick a roll-top chafer for one show-piece dish, a 4-pack for a full buffet line, or a 2-compartment chafer to serve two dishes from one spot.
Can you use them together?
Yes, and many hosts do: chafing dishes for the mains on a buffet line, plus a warming mat on the table for sides and rolls. Our Holiday Buffet Set pairs a 9 Qt chafer with a warming mat for less than buying them separately.
Frequently asked questions
Do chafing dishes need water?
Yes. Most chafing dishes use a water pan under the food pan. The water spreads the heat evenly and helps keep food from scorching.
How long does chafing fuel last?
It depends on the can. Common sizes are rated for roughly 2 to 6 hours, so check the label and keep spares for long events.
Can a warming mat cook food?
No. Warming mats and trays are designed to keep already-hot food warm, not to cook or reheat it.
