Cool soup safely: from one deep pot to shallow portions

1. Start the clock when cooking ends

Refrigerate perishable leftovers within two hours, or within one hour when the surrounding temperature is above 32°C / 90°F. This is a discard boundary, not a target for leaving soup out.

Prepare clean containers, labels and refrigerator space before serving so cooling is not delayed by cleanup.

2. Reduce depth, not just portion count

Transfer soup from the deep pot into several shallow containers. Smaller volume and more exposed surface help heat leave faster. Very large pieces of meat should be divided where appropriate.

Small quantities may be refrigerated while still hot. For a large batch, an ice or cold-water bath can help rapid chilling before or alongside prompt refrigeration; keep outside water out of the food.

• Use food-safe shallow containers
• Leave room for safe handling and expansion if freezing
• Label name and cooking date
• Do not stack warm containers tightly

3. Store a usable meal, not one frozen block

Portion by the amount you expect to reheat. Freeze portions you will not use soon, following the storage guidance for the actual ingredients and your local authority.

Do not rely on smell or appearance to decide whether food held unsafely is safe.

4. Reheat the portion thoroughly

USDA advises reheating leftovers to 74°C / 165°F measured with a food thermometer, and bringing soups, sauces and gravies to a rolling boil. Stir during microwave reheating and check more than one place because cold spots occur.

Reheat only the amount you intend to eat. Follow the strictest instruction on the ingredient label or from your local food-safety authority.
