Understanding the Shelf Life of French Onion Soup
The longevity of French onion soup in the refrigerator depends on several factors, including the ingredients used, the storage temperature, and the presence of any preservatives. Generally, homemade French onion soup without any preservatives has a shorter shelf life compared to commercially prepared varieties.
Refrigeration Guidelines for French Onion Soup
To maximize the shelf life of your French onion soup, follow these refrigeration guidelines:
- Refrigerate promptly: After cooking, allow the soup to cool to room temperature before transferring it to an airtight container. Prompt refrigeration prevents bacteria from multiplying.
- Maintain proper temperature: Keep the soup refrigerated at a temperature below 40°F (4°C) to inhibit bacterial growth.
- Use airtight containers: Transfer the soup to airtight containers to prevent contamination and moisture loss. Glass jars or plastic containers with tight-fitting lids are ideal.
Homemade French Onion Soup: How Long Will It Last?
Homemade French onion soup, without preservatives, has a shorter shelf life due to the lack of additives. Generally, it can be refrigerated for:
- Up to 3 days: If the soup is stored in an airtight container and refrigerated promptly.
- Up to 5 days: If the soup is frozen and then thawed in the refrigerator.
Commercially Prepared French Onion Soup: Extended Shelf Life
Commercially prepared French onion soup often contains preservatives that extend its shelf life. Refer to the manufacturer’s instructions for specific storage guidelines, but it typically lasts:
- Up to 7 days: If unopened and stored in the refrigerator.
- Up to 3 months: If frozen and then thawed in the refrigerator.
