how long does a jar of pasta sauce last in the fridge after opening

A jar of pasta sauce usually lasts about 5 to 7 days in the fridge after opening, as long as it’s kept refrigerated at 40°F (4°C) or below.

Quick Scoop

• Tomato-based jarred sauces are typically good for 5 to 7 days after opening.

• Cream-based sauces spoil faster, often within 3 to 4 days.

• If it smells sour, looks moldy, or tastes off, toss it even if it’s still within the usual time window.

Storage Tips

• Put the lid back on tightly right away and refrigerate promptly.

• Keep the fridge cold and avoid leaving the sauce out for long periods after serving.

• If you want to keep it longer, freezing is usually the better option.

TL;DR: For most opened jars of pasta sauce, plan on using it within about a week.
