Once the seal is broken and the sauce is exposed to air, its freshness begins to deteriorate. It’s crucial to refrigerate Rao’s sauce immediately after opening to slow down this process. When properly refrigerated, Rao’s sauce can last for 10 to 12 days after opening, maintaining its robust flavors and safety for consumption.

To maximize the shelf life of Rao’s Homemade Marinara Sauce once opened, it is essential to follow proper storage methods such as:

Shelf location

Store containers of Rao’s sauce on the refrigerator shelf instead of on the door. The door is often subject to temperature fluctuations each time it is opened, which can affect the quality of the sauce. Placing the sauce on the shelf at the back of the refrigerator, where the temperature is more stable will help ensure consistent cooling.


After opening, transfer Rao’s sauce to an airtight container and refrigerate it promptly. Keeping the sauce chilled slows down bacterial growth and helps preserve its freshness. Ensure the refrigerator temperature remains at or below 40°F (4°C) to maintain the sauce’s quality.


If you’re unable to use Rao’s sauce within the recommended time frame, freezing it is an excellent option for extending its shelf life. Transfer the sauce to freezer-safe containers or bags, expelling any excess air to prevent freezer burn. Properly frozen Rao’s sauce can last for 3 to 4 months, allowing you to enjoy its flavors at a later date.
