After opening a bottle of spaghetti sauce, it is generally safe to store it in the refrigerator for about 3 to 5 days. During this time, the sauce should remain safe to consume if kept properly refrigerated.
To maximize the shelf life of the opened spaghetti sauce, follow these tips:
Store Properly: Make sure to transfer the leftover sauce to an airtight container or cover the original bottle tightly before placing it in the refrigerator. Keeping it airtight helps prevent the growth of bacteria and maintains the sauce's quality.
Keep Refrigerated: Store the sauce in the main body of the refrigerator, not on the refrigerator door. The door is subject to more temperature fluctuations, which can reduce the sauce's shelf life.
Smell and Look Test: Before using the sauce after a few days, check for any signs of spoilage, such as an off odor, mold, or unusual texture. If the sauce looks or smells suspicious, discard it to avoid the risk of foodborne illness.
If you know you won't be able to finish the sauce within 3 to 5 days, you can consider freezing the leftovers. Freezing can extend the shelf life of spaghetti sauce for several months. Just ensure you use freezer-safe containers, leaving some space for expansion, as liquids tend to expand when frozen. When you want to use the frozen sauce, simply thaw it in the refrigerator before reheating.
Always use your best judgment when it comes to food safety. If in doubt about the quality or safety of the sauce, it's better to err on the side of caution and discard it.
