What is a Bain Marie?
A bain marie is a piece of equipment used to keep food warm over longer periods of time. By keeping food warm, it stays at the right temperature and is ready to eat for a long time.
A commercial bain marie, also called a water bath or double boiler, is a large appliance that works with gastronorm pans.
Gas or electric bains marie are popular for buffets. They come in different sizes and can provide wet or dry heat for self-service areas.

Types of Bain Maries
Wet Heat Bain Marie
A wet heat bain marie uses a chamber of hot water to keep food warm. The unit gently heats the water to a set temperature, and then you place the food pan into the water.
Best Uses for Wet Heat Bain Marie:
- Sauces and Soups: Keeps them at a perfect serving temperature without reducing or thickening.
- Stews and Casseroles: Maintains the consistency and flavor by keeping the food moist.
- Pasta and Rice Dishes: Prevents them from becoming hard or clumpy.
- Vegetables: Keeps them warm and tender without drying out.
For a buffet, use a wet heat bain marie to keep dishes like lasagna, mashed potatoes, and steamed vegetables warm and tasty.
Temperature Suggestion
The ideal temperature range for a wet heat bain marie is between 70°C and 80°C. Keeping food above 65°C is important to maintain its warmth and ensure safety by killing bacteria.
TIP
For use over extended periods, the water chamber may require the occasional refill. After service, it’s important to drain any excess water – using a bain marie with drain taps will make this process safer.

Dry Heat Bain Marie
Instead of hot water, a dry heat bain marie uses a heating element that directly heats the base of the food pan.
Best Uses for Dry Heat Bain Marie:
- Fried Foods: Keeps items like French fries, chicken nuggets, and onion rings crispy and warm.
- Baked Goods: Ideal for pastries, bread, and other baked items that need to stay warm without becoming soggy.
- Roasted Meats: Maintains the integrity and texture of roast beef, chicken, and pork.
In catering, a dry heat bain marie is great for keeping fried chicken, bacon, and hash browns warm and crispy.
Temperature Suggestion
The ideal temperature for a dry heat bain marie is also around 70°C to 80°C. This ensures the food stays warm and safe without compromising its texture.
TIP
Using a dry heat bain marie can quickly dry out hot sauces such as gravy or custard. On some models, the positioning of the elements can mean some parts of the food pan get hotter than others.

Soup Kettle
A soup kettle is a good option for keeping large amounts of one item warm instead of using a wet heat bain marie. As the name suggests, you commonly use it for soup, but it is also great for holding food such as chili, curry, or gravy.
Best Uses for Soup Kettle:
- Soups: Keeps large quantities warm and ready to serve.
- Stews and Chilis: Maintains the consistency and flavor over extended periods.
- Sauces and Gravies: Perfect for keeping sauces hot and ready to pour.
TIP
Unlike a standard benchtop bain marie, soup kettles can only hold one food type inside. Are you using it to serve a soup of the day? Use chalkboard signs to let your customers know.

Chafing Dish
When there is no access to mains electricity or gas, a chafing dish is an excellent alternative. Chafing dishes keep food warm using cans of fuel below the water pan, similar to a bain marie.
Best Uses for Chafing Dish:
- Buffets and Outdoor Events: Portable and doesn’t require electricity or gas.
- Stylish Presentations: Polished stainless steel design is perfect for hotel buffets or breakfast service.
