Bain-Marie Buying Guide: Gas or Electric, Sizes and Uses in Buffets and Restaurants

A bain-marie holds food at serving temperature using a heated water bath. Gentle, indirect heat keeps sauces smooth and prevents food from drying or burning, which is why it is a standard in buffets, hotel kitchens and catering.

How it works

The unit has a water well heated by gas burners or an electric element. Food containers sit in the hot water, so heat is spread evenly and softly. This makes it ideal for holding rather than cooking.

What to hold in a bain-marie

  • Soups, sauces and gravies

Sizing tips

  1. Count the number of different dishes you serve at once
  2. Choose container sizes that match the dishes (full, half or third size)
  3. Leave room for refilling from the back

Complete the hot line

Pair the bain-marie with a gas range, stock pot stove and a work table. Read our gas vs electric range guide for fuel advice, or request a quote.

Frequently asked questions

What is a bain-marie used for?

It holds cooked food, sauces and soups at a safe serving temperature using gentle heat from hot water.

Gas or electric bain-marie?

Choose gas where gas is available and cheap; choose electric where gas is restricted or you need precise, quiet heating.

Does it need water?

Yes. Water in the well surrounds the food containers and spreads heat evenly. Keep it topped up.
