Marinara sauce is made from a mixture of tomatoes, garlic, and herbs, which are all natural preservatives. This means that the sauce has a pretty good shelf life, even after opening. However, it's crucial to store it in the fridge at a temperature of 40°F (4°C) or below to prevent the growth of bacteria and mold.
If you want to extend the life of your marinara sauce, you can try freezing it. Yes, you read that right - freezing! Simply pour the sauce into an airtight container or ziplock bag, label it, and pop it into the freezer. The sauce will keep for up to 6 months, and when you're ready to use it, just thaw it in the fridge or at room temperature.
Now, you might be wondering, what about canned marinara sauce? Well, the good news is that canned sauce can last for up to 5 years in the pantry, as long as it's stored in a cool, dry place. But, once you've opened the can, the sauce will only last for 5 to 7 days in the fridge. So, be sure to use it up quickly or freeze it for later.
