How long is refrigerated leftover spaghetti sauce good for?

Refrigerated leftover spaghetti sauce is generally good for 3 to 4 days.

Here are some factors that can affect the shelf life:

* Type of sauce: Tomato-based sauces tend to last longer than cream-based sauces.

* Storage: Store the sauce in an airtight container in the refrigerator.

* Temperature: Keep the refrigerator temperature at 40°F (4°C) or below.

Signs of spoilage:

* Off-odor: If the sauce smells sour or rancid, it's likely spoiled.

* Color change: The sauce may become darker or discolored.

Safety tips:

* Always reheat the sauce thoroughly before consuming.
